對于冷加工后經再結晶退火處理的zr - 4合金,軋制方向的低周疲勞壽命比橫向要大。隨著_ p的降低,兩個方向的低周疲勞壽命的差別相應增加,這是由於合金中存在織構的緣故。冷加工后經再結晶退火處理的zr - 4合金在固溶處理后,抗疲勞性能明顯降低,這主要是由於固溶處理降低了合金的schmid因子;固溶處理后在相區的退火對疲勞性能有影響,即500 1 . 5h退火的抗疲勞性能要優於750 1 . 5h退火,這主要與500 1 . 5h退火的合金中沉澱相粒子的數量較少有關。In other words, we depend on the strong ability of classification of nn to recognize the characters of a car plate ; 4 ) under the precondition of inadequate samples, we introduce the technology of additional sample in the progress of characters recognition which uses experiential knowledge to construct some sample artificially and then inserted these samples into the sample set in order to improve the performance of network

在封閉式循環中,將核廢料再次循環利用看起來就像是件理應去做的事:用比較少的燃料就可以得到同樣的能量,而且因為得儲放數千年的放射性材料減少了,所以核廢料長期存放的問題也減輕了。Main conclusions drawn from the analyses of calculating results are as follows : ( 1 ) the microwave absorption of atmosphere gas have obvious attenuation at the wavelengths for cloud detection, thereinto, the water attenuation effect changes greatly, so the 94ghz cloud detecting radar should have water vapor attenuation correction scheme. ( 2 ) when 37ghz and 94ghz radars detect clouds, the difference between the atmosphere and cloud attenuation and the large variety of radar reflectivity conduce the intension of the radar backscatter signals change. ( 3 ) for the thin cloud layer and low water content of cloud, 37 - ghz radar backscatter signals are not as good as 94 - ghz radar, that is to say that the 94ghz radar has better capability in thin clouds detection
本工作得出如下結論: ( 1 )大氣氣體的微波吸收在測雲波段產生明顯的衰減,其中水汽衰減效應變化很大;即將上天的空間94ghz測雲雷達必須有水汽衰減訂正方案; ( 2 ) 37ghz和94ghz雷達測雲,由於大氣和雲衰減不同和雷達反射率的很大差異,導致雷達回波信號強弱不同; ( 3 )對雲層較薄、含水量較少的雲,在不計雷達參數的情況下, 37ghz雷達回波信號不如94ghz測雲雷達,也就是說94ghz對薄雲有更強的探測能力;對雲層較厚、含水量大的雲,由於強衰減的作用, 94ghz雷達回波信號小於37ghz雷達; ( 4 )從大氣衰減的不利因素方面考慮,空間94ghz雷達測高層薄雲的效果最好;測低層薄雲時需要考慮氣體衰減訂正;因濃厚雲的強衰減作用,探測其中下部的能力大大減弱,不僅要進行衰減訂正,而且要藉助其他信息來反演整個雲層的含水量垂直分佈; ( 5 )為了獲得從極薄到極濃厚雲的垂直分佈探測能力,未來測雲雷達系統最好採用雙波長甚至三波長(如94 、 37和13ghz ) 。Aiming at the study actuality of fan performance monitoring system and analysis of fan performance curve changes affected by inlet - box and the different fixed - angles of guide blades in the course of installation, a fan flow monitoring model based on rbfnn in whole flow zone was established in this thesis. in the model, the method of no throttle and fan performance curve were used as basis. and on the basis of that model, fan performance curves of 4 - 73no. 8d were approached with experimental data of different speed, different opening - angles of guide blade and different resistance of pipeline, the precision and the error law of model were studied
本文針對電站風機性能監測系統研究較少的現狀,在實驗的基礎上分析了現場加裝進氣箱和由於安裝造成的導流器葉片開度不一致對風機性能曲線的影響,並在此基礎上採用無節流方法測量流量,以風機調節性能曲線為依據,建立了基於徑向基函數( rbf )神經網路的風機流量全程監測模型;以實驗室4 - 73no . 8d離心風機為研究對象,探討了rbf神經網路差壓模型在變轉速、變導流器開度和變管網阻力等工況下的應用精度和誤差分佈規律;最後用visualc + +語言開發了風機性能在線監測系統。The results indicated that the dimension, shape and purity of base material could meet the functional demand of solid lubricant ; the thermal decomposition temperature of ptfe resin exceeds 400 c, but organic and inorganic packing filler added in ptfe made the water absorption rate of composite material increased, melting temperature and decomposition temperature decreased, in the meanwhile oxidative decomposition reaction was accompanied ; polar groups such as c = o, c - o - c and so on in the carbon fiber surface is advantageous to increase compatibility with other components and interlayer shearing strength ; uniform design experimental method could help to find the relationship between formula and frictional property by relatively small tests. the developing trend of each formula ' s friction coefficient could be showed by fitting curve ; the friction coefficient with no copper powder or graphite in formula was relatively big. this fact showed that copper powder and graphite should be used cooperatively ; it was found that when the ratio of copper powder to graphite by weight is 15 : 60, 30 : 30 - 40 and 60 : 15 - 30 respectively, the friction coefficient was relatively small. the degree of crystallinity of pure ptfe reached maximum by air cooling and the abrasion loss also reached maximum among three ones ; at the same time, the abrasion loss of solid lubricant sample was also the biggest among three ones ; when solid lubricant matched with 45 # steel axle or gcrl5 steel axle, lubricant transfer film could be formed on metal surface, thus direct contact between the surface of metal friction pair rings was reduced. their working life was elongated extremely ; there was mainly much graphite, a little ptff, moo3, feso4, cus and so on in lubricant transfer film
試驗結果表明:所選原料的尺寸、形狀及純度可滿足固體潤滑劑的性能要求;聚四氟乙烯樹脂熱分解溫度超過400 ,但在ptfe中加入無機填料會使復合材料吸水率提高,熔融溫度及分解溫度降低,且伴有氧化分解反應;碳纖維表面含有c = o及c - o - c等極性基團,有利於提高其與其它組分的相容性,提高層間剪切強度;均勻設計試驗方法能夠用較少的試驗次數找出配方與摩擦性能間的關系,擬合曲線基本能表示各配方的摩擦系數發展趨勢;配方中不加銅粉或不加石墨,其摩擦系數均較高,說明銅粉和石墨應該配合使用;當銅粉15份、石墨60份時,銅粉30份、石墨30 - 40份時,銅粉60 、石墨15 - 30份時,摩擦系數均具有較低值;純聚四氟乙烯樹脂在空氣冷卻時結晶度最大,磨損量也是三者中最大的;同時,固體潤滑劑試樣在空氣冷卻時的磨損量也是三者中最大的:不論是固體潤滑劑與45 #鋼軸配副或是固體潤滑劑鑲嵌入銅套后與gcr15鋼軸配副,在金屬表面均可形成潤滑轉移膜,從而減少金屬摩擦副表面間的直接接觸,大大延長其使用壽命;轉移膜中主要含有較多的石墨、少量聚四氟乙烯、 moo 。As to the stochastic simulation of stochastic biological processes, if only use stochastic petri net, although it has standard graphics expression, which is isomorphic to markov chain, along with the increase of models ’ scale and complexity, the number of states will increase exponentially, so it is very difficult to analyze models by the method which stochastic petri net has ; if only use stochastic algorithm, which has rapid simulation speed, but lack of intuitive graphical expression
對于隨機生物過程的模擬,如果只採用隨機petri網模擬生物隨機過程,其優點是形象、直觀,缺點是隨著模型的規模和復雜性的增加,狀態的數量呈指數性地增長,出現模型狀態空間的爆炸問題,用隨機petri網本身的分析方法很難分析整個系統的性能;如果只採用隨機模擬演算法模擬,其優點是速度較快,但是缺少形象的圖形表達,不利於模擬技術的應用。Compare with 1998, the 2001 leonids was even more numerous, and the proportion of fireballs were higher. however, explosives ones which illuminate ground objects, leave a smoky train, or even produce cracking sound, are much less than 1998 shower

在土壤細菌總數上,夏季的細菌數量最多,其次分別為春、秋、冬各季;在土壤中降解氧樂果的細菌數量上,夏季土壤中的降解菌株數量也最多,其次分別為春、秋、冬各季,土壤磷的含量與降解氧樂果細菌的數量之間並沒有太大的相關性( r = 0 . 494 ) ;在降解菌占細菌總數百分比上,秋季降解菌株所佔百分比最大,為0 . 547 % ;在降解菌株中,芽孢桿菌屬( bacillus )在每一季節所佔的比例都是最大的,春、夏、秋、冬分別為44 . 44 % 、 50 . 00 % 、 48 . 15 % 、 47 . 22 % ,其它菌屬所佔比例都比較少,這可能跟土壤的基本性狀有關,春夏秋冬四季的輪換,氣溫的變化,植被的差異,耕作的不同,比較適合抗逆性較強的芽孢桿菌屬( bacillus )的生長。This incubation adjustment of parents makes the synchrony in hatching and the hatching intervals of nestlings shorter than the laying intervals of eggs. this phenomenon was perhaps resulted from the incubating behavior difference of parents in laying time and incubating time. the research also found that the growth rate and survival rate in the latest hatched nestlings in little egret were lower than the earlier hatched ones
卵的孵化時間與產卵順序呈負相關性,先產的卵比后產的卵所需孵化時間相對較長,此現象產生是由於親鳥在產卵期和產卵后的孵化行為不一致造成的,這種孵化調節使同一窩雛鳥孵出時間具有相對集中的趨勢,雛鳥出殼的時間間隔比產卵的時間間隔短;另一方面,在白鷺雛鳥的生長過程中,最晚出殼的雛鳥生長水平和成活率明顯落後于早出殼的雛鳥,而池鷺由於窩卵數和窩雛數為5的數量相對較少,雛鳥生長均衡。It was further testified that to insert a small lattice into a large one would spend less time
並進一步論證了把節點數量較少的格插入到節點多的格中比反著做更省時間。The average values of the stomatal index in the non - leaf organs in ca cereals were smaller than those of leaves. blanke put forward a new physiological process in fruit, ' fruit photosynthesis ', and featured with lower stomatal frequency ( blanke, 1989 ). the results here also showed that the significant lower stomatal frequency on non - leaf organs, indicating that the new physiological process might exist in these organs of cereals as well
