緩發臨界 的英文怎麼說
中文拼音 [huǎnfālīnjiè]
緩發臨界
英文
delayed critical-
Various attempts have been made to study the effect of electrochemical polymerization processes including temperature, electrolyte composition and the deposited location on the strength and brittle - tough properties. by the mechanical measurement and testing, we found, compared with the mixed electrolyte composition of isopropyl alcohol ( ipa ) + 5 % boron trifluoride diethyl etherate ( bfee ) + 5 % polyethylene glycol ( peg ), the better mechanical properties of conducting ppy films were given by the mixed electrolyte compositon of ipa + 5 % bfee + 5 % deg
結果發現，當添加劑peg的濃度不變時，改變bfee的濃度可以改變薄膜材料的性能，其中以30的bfee濃度為最佳；當固定電解液中bfee濃度不變時，改變添加劑的濃度對制備的薄膜性能參數影響不明顯，但以peg100為臨界；降低溫度，可以使薄膜生長減緩，有利於得到性能更好的薄膜。Water - inrush from coal floor is found to have two routes, catastrophic and slowmoving, and to have divergent character and modality softening character and so on
進一步分析，發現煤層底板突水具有突變、緩慢兩條路徑，並在突水臨界點附近具有發散性和4模態軟化等性質。Through analyzing bed ' s response to wave, in the condition that super - stratum is more hard and second - stratum is more soft in region of interest, super static interstitial hydraulic pressure amplitude die away rapidly between stratums, before in sight of boundary between hard and soft stratum, plane effective pressure increase to max. shear stress reach peak value when bed thickness is approximately 2. 7 meters, then it will decrease to the minimum on the place where the flexible soil has a common boundary with the rigidity, so the boundary is the most destroy plane on engineering. on the basis of reconnaissance in situ, in normal situation of sea, the structure slides to the basin along the boundary
通過對底床在波浪下的響應分析，對于研究區底床上層較硬而第二層較軟的情況，超靜孔隙水壓力幅值在層間交界處迅速衰減，在臨近硬、軟地層交界處前，水平有效應力增至最大，剪切應力在底床厚度大約2 . 7米左右達到峰值，然後減小，到硬、軟層土交界位置，達到最小，因此這個界面就是最容易發生破壞的工程軟弱面，現場勘查證明，即使在正常海況下，構築物也會沿坡以此交界面為滑動面，緩慢向「盆」底滑動。Secondllv in the 1 d random traffic flow model. the relation function between the correlation and the creation. disappearance. brake probabilities of the vehicles is presented. according to the statistical mechanical approach to the spatial correlation functions. the theoretical results agree with that of the computer simulation. thirdh. based on the bml model. a main - road traffic flow model with two speeds on two dimensions is designed. this model simulate the traffic situation of one main road and several branches in the cit traffic lights placed on the crossing. vehicles breaking ~ vhile running and turning to other direction while jamming. we investigate the ~ ' e1ocitv and flo ~ ~ of the model when the initial densitvthe brake and turning probabilities. the green to signal rati3. thc number of the branches and the period of the signal are changed. then the reasons causing all the kinds of phenomena are analvzed. finallv. we simulate the bml model using the method of lattice boltzmann which ~ vas brought out by liu mu - renand obtain the velocity - density graph similar to the previous result. the upper critical densiw above which there are oniv jamming configurations. and the lo ~ ver critical density below which there are only moving configurations are the same as before. the boltzmann function which is on the lattices shows the moving and jaxmning transition obviouslv. thus it proves the possibilit of this method on the traffic research
接著，建立了和研究了二維二速的主幹道模型，該模型模擬了城市交通中一條主幹道，多條支道的交通情況，在幹道與支道的交叉路口設置紅綠燈，車輛在運行中可以有對突發事件發生反應的剎車，在發生堵塞時，路口的車輛可考慮通過轉向來緩解交通等各種實際情況的發生，給出了車輛演化的演化方程，並通過計算機模擬，研究模型在改變車輛的初始密度、剎車概率、轉向概率、支道數、紅綠燈信號的綠信比、紅綠燈信號周期等各種情況下支、主幹道車輛的速度、流量的變化，並分析在各種情況下交通狀況的成因，提出改善交通的有效措施。最後，在劉慕仁提出的用格子boltzmann方法研究一維決定論交通流的思路下，將此法推廣到對二維bml模型的模擬上，得到了與用以往方法的研究結果相類似的速度-密度圖線，且車輛從運動相到堵塞相轉變的上下臨界密度是一致的，同時分別給出車輛在處于暢通相和堵塞相時， boltzmann函數在格子上的分佈情況，進一步驗證了此法的可行性。This change is a break when the outside conditions exceed a threshold value with gradually variety. the break is equal to the non - equilibrium phase transition in thermodynamics. ( 6 ) there are two kinds of stable channels
河型轉化是在外界條件緩慢變化過程中，超過某一臨界值而發生的突變，這種突變相當于熱力學中的非平衡相變，是由某些參數的漸變引起的從量變到質變的一個過程。The world economy strids forward to be knowledge, to be information and to be service step by step under the promotion of sci - tech revolution since 1970 ", and structural contradiction is prominent in china ' s economic development ; the implementation of non - equilibrium development strategy of regional economy has promoted the east coastal areas made a leap economic development, while the economic development of west areas is relatively slow, and the gap between east and west is expanding continuosly
20世紀70年代以來，在新科技革命的推動下，世界經濟逐步向信息化、網路化和服務化邁進，我國經濟發展的結構性矛盾突出，在世界產業分工體系中處于不利地位，產業結構面臨優化升級的嚴峻考驗；區域經濟非均衡發展戰略的實施，推動東部沿海地區經濟跳躍式發展，而中西部地區經濟發展相對緩慢，東西部差距不斷擴大。分享友人
