The polyester fibre of resisting bacterium is one without which people can t live in modern times, but how to restrain the bacterium propagating excessively and keep people in health is a most important goal that fabrics and clothing industry are striving for. fibre of resisting bacterium can kill the bacterium effectively with the ratio of more than 99 % and it can restrain microbes. the polyester fibre of resisting ultraviolet radiation is also widely used. with the decreasing of ozonospheres in the atmosphere, there are more ultraviolet radiation in the sunlight which do harm to our skin, especially for those men working outdoors, it is more important to think about the way to lessen the harm. the polyester of burning - resisting has attracted more attention at home and abroad and burning - resisting textiles has been advanced definitely by law in many countries. our nation has also made strict claims in some special areas, such as fabrics in vehiciles and vessels, decorative fabrics in hotels. the everlasting burning - resisting fibres and textiles are badly needed. infrared ray fibre is also a new functional one that can absorb and reflect infrared ray after being processed physically. it s functions include physical therapy wet - ejecting and bacterium - restraining. this warm - preserving material can absorb the emitting heat from our bodies, at the same time it can also absorb and reflect the needed 4 - 14 urn wavelength ultraviolet radiation and accelerate netaboiism. fibre of resisting infrared ray is important in military areas
抗菌纖維具有永久的抗菌性，對金黃色葡萄球菌、大腸桿菌殺菌率大於99 ，能有效抑制細菌繁殖，起到抗菌防臭作用；抗紫外線聚酯纖維的用途也是異常廣泛的，隨著大氣層中臭氧層的日漸稀薄，日光中的紫外線日益增加，對人體皮膚形成極大危害，尤其對于長期從事野外工作的人，因此設法減少紫外線對人體的傷害顯得尤為重要；阻燃聚酯纖維則是一種倍受國內外人士密切關注的纖維，紡織品阻燃在許多國家已有明確法令規定，我國也逐漸在某些特殊使用范圍做嚴格要求，如車船內用紡織品，高級賓館的內裝飾織物等，而且具持久性阻燃性的纖維和織物是現在更為需要的，真可謂用途非常廣泛；遠紅外纖維也是一種經過物理改性后具有吸收並反射遠紅外線的新型功能性纖維，是一種具有優良理療功能、熱效應功能和排濕透氣抑菌功能的新型紡織材料及保溫材料，能吸收人體自身向外散發的熱量，吸收並反射回人體最需要的4 14 m波長的遠紅外線，促進人體的新陳代謝；抗紅外線纖維，則在軍事上有著重要的作用。Be opposite this of 1992 cloth " labor law " revise share 44, new after revising " labor law " have the following characteristic : suited to build the real case that realizes formal diversity with the adjustment that develops structure of system of socialist market economy, economy, state ownership already, highlight again was aimed at increasingly complex and changeful working relationship ; the maintenance that highlighted labour union function, made clear workers congress system and collective contract system shift of power of these two main thought, aggrandizement labour union organizes construction, organize broad worker in labour union to provided legal basis and safeguard for utmost ground ; increased the protective strength to labour union cadre, aggrandizement specific safeguard, make labour union cadre ok more the function that fulfils his duty to fulfill labour union responsibly ; protected labour union to produce bridge and bond effect better, fulfilled labour union to share politics, economy, culture and the approach that the society lives, made clear the essential mechanism that labor of labour union mediate concerns ; those who made clear union funds capture range, aggrandizement of union funds capture strength, ensured labour union to organize the necessary material base that develops function of labour union of activity, implementation lawfully ; set legal liability, made clear the punishment to violating principal part, enhanced law to deter force
這次對1992布的《工會法》的修改共有四十四條，新修改後的《工會法》有以下特點：既適應了建立和發展社會主義市場經濟體制、經濟結構的調整、公有制實現形式多元化的實際情況，又突出針對了日益復雜多變的勞動關系；突出了工會的維護職能，明確了職工代表大會制度和集體合同制度這兩個主要維權手段，強化了工會組織建設，為最大限度地把廣大職工組織到工會中來提供了法律依據和保障；加大了對工會幹部的保護力度，強化了具體保護措施，使工會幹部可以更加盡職盡責地履行工會的職能；更好地保護了工會發揮橋梁和紐帶作用，落實了工會參與政治、經濟、文化和社會生活的途徑，明確了工會調處勞動關系的根本機制；明確了工會經費的收繳范圍，強化了工會經費的收繳力度，保障了工會組織依法開展活動、實現工會職能的必要物質基礎；規定了法律責任，明確了對違法主體的處罰，增強了法律威懾力。With the construction of the west of our country developing at top speed and the need of construction of mountainous expressway, the tunnel engineering, especially the tunnels on the mountainous expressway, will be increased. if the design of support structures of the tunnel still adopts traditional design methods, it will be difficult to give full considerations for the reasonability in economy of the sections of the support structures and for the reliability of bearing capacity and stability of the support structures
隨著我國西部建設的高速發展和山區高速公路建設的需要，隧道工程特別是山區高速公路隧道工程將會日益增多，隧道支護結構的設計若仍採用傳統的隧道支護結構設計方法將難以充分兼顧支護結構斷面經濟上的合理性和支護結構承載力與穩定性的可靠性，往往安全系數偏大，不能達到「最優設計」的目的。Discuss the generation of test strategy for diagnosis based on information gain maximization and conditional entropy minimization. this approach can be used into the testability analysis and the optimization of test strategy for diagnosis

文摘:生物入侵是不均衡世界的一個永恆話題，尤其是當人類有意或無意地引入物種后.很多引入顯然是無害的，但另外一些則有著嚴重的後果，會給入侵地的生物以至於整個生物群落造成影響.本文總結了分佈區擴張的常見模式，概述了它們對遺傳多樣性和種群結構式樣所造成的影響.描述了如何根據以一批遺傳標記所得到的遺傳多樣性式樣來推斷入侵途徑，來揭示伴隨擴張選擇和漂變在形成種群遺傳樣式中的作用.本文對日益增多的群體遺傳學方法進行了總結，這些技術可以用來在不同的時間尺度上推斷種群規模所發生的巨大變化（瓶頸效應及種群擴張） .最後，我們以歐洲櫟癭蜂（膜翅目，癭蜂科，癭蜂族）一系列入侵的數據為例對一些方法進行了說明.從500 10000年的時間尺度上，多態的等位酶位點上等位基因頻率的數據表明: 1 ）遺傳多樣性沿入侵路線呈不斷下降的趨勢，支持了冰河期避難所作為遺傳多樣性中心的作用; 2 ）入侵地區的種群與該物種原產地的種群相比，遺傳上的分化更為強烈.這種種群結構在空間上的變異可能是被櫟癭蜂開發的資源尤其是櫟樹寄主在斑塊上出現變異的反映In order to measure the characteristics of such semiconductor optical amplifier, we adopted a set of measurement system. this measurement system can be used to measure the characteristics of all kinds of active or inactive optical passive components. such device presents good polarization insensitivity ( < 0. 9db ), wide 3db bandwidth ( > 33nm ) at 0 - 200ma and different input signal light wavelength and power, the maximum fiber - to - fiber gain of 10db, lossless operation current of 50 - 75ma for different input signal light wavelength and power, large extinction ratio ( > 50db ) and lower noise figure ( nf ) ( < 8db )
與張瑞英博士一起，首次利用該種有源區結構制備出偏振不靈敏半導體光放大器，並在0 - 200ma注入電流范圍內獲得33nm的3db帶寬，在不同信號波長，不同信號功率0 - 200ma的注入電流范圍內，偏振相關損耗均《 0 . 9db ，在耦合差損為7db / facet的條件下，最大fiber - to - fiher增益達10db ，無損操作電流為50 - 70ma ，消光比達50db以上，而噪聲指數則低於8db ，最小可達4 . 6db 。Statistically, it makes a quantitive analysis on the evolvement of the country economic structure in xi ' an city, the economic benefit of the changes in industry structure, the effect on labor resource collacation in industry structure and the effect of the increasing income of countrymen in industry structure changes, which discloses a rule of the industry structure evolvement in country. the putting forward of the non - agriculture industry in country, especially the rapid increase in country industry will promote the rise of the country industry level for a long term. the country industry structure influences a lot the increase of the farmer ' s income which is also affected by agriculture structure and planting structure, but less. the non - agriculture industry plays a main role in the increase of farmer ' s income. for the low level of the townlization and industrialization, developing industry, construction and commercial in country is very feasible to resolve the problem of spare labors in country. it is strengthening labors transferring and reducing the modulus of labor over the infield that farmers income could be kept increasing. after a theoretical analysis and twenty years practise in the regulation of country economy structure after the reform and opening policy in xi ' an, a new thought of regulating country economy structure in xi ' an is put forward that a strategic regulation must be taken in country economy structure and the agriculture structure must be optimized. moreover, an expanding agriculture must be developed and transfer the spare labors in country effectively. so the government function during the regulation of country economy structure is transferred to : the first one, making the stress policy in the regulation of country industry structure. 2ndly, strengthening the force in regulating country industry structure ; 3rdly, making a plan on the regulation of country industry structure ; 4th promoting the optimizition and upgree of industry relying on sci - tech progress ; 5th enhancing the townlization and optimizing the country industry structure ; last one, improving the quality of labors in full scale
本文在概述經濟結構理論的基礎上，第一次系統地研究了西安市農村經濟結構調整，用數據統計的方法，定量、定性地分析了西安市農村經濟結構演變的軌跡，分析了產業結構變動的經濟效益、產業結構勞動力資源配置效應、產業結構變動的農民收入增長效應，揭示了農村產業結構演變的規律。提出農村非農產業，尤其是高速增長的農村工業，對促進農村產業水平的提升起著長?推動力的作用；農民收入增長直接受農村產業結構的影響最大，農業產業結構、種植業結構對農民收入有影響，但作用不可高估；非農產業是農民增收的主要支撐力量，解決農村余勞動力在城鎮化、工業化水平不高的情況下，切實可行的選擇是在農村發展工業、建築業、商飲業等非農產業；農民收入要保持快速增長態勢必須加大農村勞動力轉移力度，減少耕地承載勞動力的系數。通過理論分析，結合西安市改革開放后20多年的農村產業結構調整的實踐，提出了西安市農村產業結構調整的發展思路及目標、原則，明確指出了政府在農村經濟結構調整過程中的職能轉變的重要方面：一是制定農村產業結構調整的傾斜政策，二是加大對農村產業調整的投入力度，三是制定產業結構調整的規劃，四是依靠科技進步促進產業優化和升級，五是加快城鎮化過程，優化農村產業結構。The results show that wavelength locates in gain zone of semiconductor optical amplifier, and have higher peak power and proper time delay between the two pulses for the second order super gauss control pulse in semiconductor optical amplifier. a high quality amplified signal pulse can be achieved. the chirp can be reduced notability by using cascading soa in cross gain modulation based on soa, and the distance and the peak power of conversion optical pulse can be increased notability, and we can let down the demand for wavelength based on xgm in soa and enhance the flexibility of wavelength conversion
我們應用二階超高斯光脈沖與高斯信號脈沖同時注入soa和應用soa與非線性光學環鏡（ nolm ）相結合的方案來對信號脈沖進行壓縮整形，模擬顯示，在調節系統合適參數的情況下，波長位於soa增益區的二階超高斯控制光脈沖在具有較高的峰值功率和適當時延下輸入soa時，最後可以得到放大的高質量超簡訊號光脈沖；在基於soa的交叉增益調制（ xgm ）全光波長轉換中，採用級聯的soa能有效地使反轉光脈沖的頻率啁啾得到有效降低，波長向下轉換的距離和反轉光的峰值能量都得到明顯提高，降低了利用交叉增益調制（ xgm ）波長轉換中對波長精度的要求，從而提高了波長轉換的靈和性。Then, by the comprehensive analysis of essential conditions for stone forest development, and the quantitative study on the evolution phases of bajiang karst catchment and the spacial coupling analysis of its hydro - geomorphological system, the paper studies the relationship between the evolution of bajiang karst drainage area and the development of stone forest, and, combined with the evolution history of the catchment, puts forward a model concerning the relationship between the evolution of bajiang karst catchment and stone forest development, in the mechanism of " tri - level erosion ", if a < s < c, the visible and actual height of stone pillars will keep on increasing, meanwhile, soil layer among stone pillars will become thicker and thicker, so the the height of stone pillars " root will become higher and higher, too
在「三重剝蝕」機制中，若a s c ，石柱的可見高度和實際高度會不斷增高，同時，石柱的根部的土層會增厚，其土下部分的高度也會不斷增大。若a c s ，說明石柱的實際高度在增加的同時，其可見高度也在增加，但土層會變得越來越薄，最終當底土被完全剝蝕掉后，氣下溶蝕和土下溶蝕的差異消失，此時a接近於c ，石柱的實際高度將停止拔高或極緩慢增長，並在各種物理、化學風化的作用下而變得日益矮小。若s a c ，石柱的可見高度將趨于變矮，但驅動石林發育的土層厚度將會增大。The payments for capital and labor are totally set by market power and capital ( labor ) suppliers of any firm have no power to alter the transaction terms with its labor ( capital ) suppliers to their advantage and thus every firm generate zero economic profit. every firm ' s value is equal to the sum of the market prices of the human assets and physical assets that it use and thus the formation and disbandment of a firm have no influence on the interest of any of its members. through an efficient comparison of production within the firm and the scattered individual production coordinated through markets, the dissertation reveals that the origin of the power relationship phenomenon within the firm is that the suppliers of the resources to the firm in real world are unable to enter into legally binding complete contracts as walras assumed
在一般均衡範式中，企業是一個追求利潤最大化的原子；企業的生產過程被描述為一個「黑箱」 ，它自動地、無摩擦地把任何一組投入轉化為既定的技術約束下所能生產的最高產出；資本和勞動僅僅是生產過程中不同類別的投入，它們之間的關系是對稱的，它們各自的報酬都是完全由市場整體的力量決定的，任何一個企業的資本（勞動）提供者都不可能為了增進其自身的利益而改變與勞動（資本）提供者的交易條件，從而任何一個企業產生的經濟利潤都為零；任何一個企業的價值都等於該企業使用的人力資產和非人力資產的市場價格之和，組成一個企業不會增進任何參與人的收益，解散一個企業也不會降低任何參與人的收益。After 1989, the increase of demand slowed down and facing the complexion of low degree of industrial concentration of product market and financial strain of medi um and small - sized enterprises caused by the circulating trap of " credit squeeze - - - bad loan ", the advantageous enterprises " " wallow in money ", specifically, those listed companies that could finance from the stock market, began to take predatory pricing strategy in succession and tried to enlarge market share and obtain high return by squeezing medium and small - sized enterprises out of the market after 1998, the vicious circle of deflation and " credit grudging " of banks in product and credit markets, overcapacity, the difficulty of retreating of loss - incurring enterprises in some industries from the market for institutional reasons and over - competition in some industries, led to the incessant decrease of enterprises " global income, persistent increase of rate of debts and constant rise of ratio of bad assets of banks, which further intensified the vicious circle of deflation and " credit grudging " of banks
如在改革開放初期，在產品市場需求旺盛和信貸市場預算軟約束的情況下，各類企業的最優決策就是採用高負債、高擴張的「負債的有限責任效應」策略來搶占市場並獲得高回報； 1989年以後，需求增速開始放緩，面臨產品市場產業集中度較低和信貸市場「信貸緊縮-不良貸款」循環陷阱導致的中小企業資金緊張的局面， 「錢袋鼓鼓」的優勢企業（尤其是那些可以通過股票市場融通資金的上市公司）紛紛採用掠奪性定價策略，試圖通過把中小企業擠出市場來擴大市場份額並獲得高收益； 1998年以後，產品市場和信貸市場形成了通貨緊縮和銀行「惜貸」惡性循環的狀況。產品市場上部分行業生產能力嚴重過剩，且由於體制等原因導致虧損企業無法退出，因此這些行業中出現了過度競爭的現象，企業總體收益的不斷下滑、負債率不斷提高以及銀行不良資產率的持續上升，又進一步加強了通貨緊縮和銀行「惜貸」的惡性循環。Note that all these structures are numerically simulated firstly and then verified by the experiments. fourthly, in accordance with the need of gain control in a wavelength division multiplexed system, a gain - clamped l - band edfa using a single fiber bragg grating ( fbg ) is proposed. based on the giles model with ase, numerical simulation for the all - optical gain - clamped edfa is carried out
最後給出一組使edfa在箱制增益的同時可以保持增益譜平坦的最佳結構和放大器參量;最後，初步介紹了光纖的非線性效應的產生機理及其對光通信系統的影響;實驗研究了應用edfa測t布里淵散射闡值的實驗裝置與方法。Every input port features a dedicated analog stage that can be switched from - 10 dbv to 4dbv, as well as a variable amp with up to 18 db gains
每個輸入埠最大的特色是能使用- 10dbv與4dbv互相切換的類比調整，也具備了可調至18db增益擴大功能。Meanwhile, if the new technology can reduce the cost sharply, the social welfare when two firms adopt the new technology may be lower than that when only one firm adopts it. this means that stronger incentive regulation and asymmetric regulation induce “ too many innovation ”. on the other hand, if the innovation is expensive and risky, and imitation is easy, the stronger incentive regulation and asymmetric regulation may increase the imitation profits of inefficient firm, so that it would adopt the waiting - imitation strategy, and this would reduce the aggressive innovation profit of efficient firm and prevent either firm from innovating
此時，若新技術能夠大幅降低生產成本，則兩個廠商都採用新技術時的社會福利可能會低於單個廠商採用新技術時的社會福利，即強激勵性規制政策和不對稱規制政策會引發「技術創新過度」 ;反之，當創新成本很高，且風險較大，模仿又比較容易時，強激勵性規制政策和不對稱規制政策可能會增加低效率廠商的模仿收益，從而使其嚴格採取等待-模仿策略，這會減少高效率廠商的進攻性創新收益，從而削弱它的創新動力，並最終阻礙自然壟斷產業的技術進步，此時，強激勵性規制政策和不對稱規制政策導致了「技術創新不足」 。In the fierce market competition, it ' s impossible for any enterprise to remain the best in all business. by uniting other up and down stream enterprises, it must set up a trade supply chain in which all enterprises share economic benefit and relevant business. therefore, they can succeed in sharing complementary advantages and make full use of all possible resources to adapt to the competitive environment of socialized mass production, making themselves more competitive in the market and becoming win - win and gaming sustaining development
任何企業在激烈的市場競爭中，都不可能在所有業務上成為最傑出者，必須聯合行業中其它上下游企業，建立一條經濟利益相連、業務相關的行業供應鏈，實現優勢互補，充分利用一切可以利用的資源來適應社會化大生產的競爭環境，共同增強市場競爭力，實現雙贏，才能獲得持久發展。Based on internal rate of return as dynamic index of financial evaluation, the authors quantitatively analyse the critical point of investment inflation for a project, which can be explained as follows. assuming that the project is in a definite time limit during which the internal rate of retum should not be less than minimun attractive rate of return ( marr ), an analysis is made on the critical value of allowable maximum inflation of investment cost. similarly, assuming that the project is in a definite investment, an analysis is made on the critical point of allowable maximum delay of time limit for the project. by critical analysis of inflation of investment and delay of time limit for a project, an investigation can be made on the capacity for a project to bear the risk of investment inflation and time limit delay ; and then a scientific basis can be offered for arranging invesetment and drawing up schedule of construetion
根據建設項目財務評價的動態評價指標? ?內部收益率，定量地分析建設項目的投資膨脹臨界點.假設在工期一定情況下，研究分析項目的內部收益率應該至少等於國家規定的行業基準收益率時，其允許投資費用的最大膨脹臨界值.類似於投資膨脹臨界分析，假設在項目投資一定情況下，得到允許建設工期的最大膨脹臨界點.通過投資與工期膨脹臨界分析，可以考察投資項目承受投資增加和工期拖延的風險能力，為合理安排投資和編制施工進度提供科學依據Then the present capacity of gsm and cdma system is analyzed and the cellular system total capacity adopting this co - frequency transmission scheme will be discussed in detail. it can be estimated that such an overlay has the potential of enhancing the overall spectrum efficiency and system capacity and it can provid e for the flexibility of spectrum utilization. finally this scheme will be simulated and then we analyze the relationship between spread spectrum processing gain, system capacity and mutual interference according to simulation results
