  1. The research consist of four parts. the first part is multiplication, purification and electron microscope examination of the avian encephalomyelitis virus. a 1 : 5 dilution of isolate - nh937 of aev and control group of pbs were inoculated to susceptible 6 - day - old chickens embryos. respectively. after incubation for 10 days, the urinay vesicle liquid was collected. making a comparison the size of the chickens embryos between the test group and the control group, the results showed that the size of the control group is bigger than that of the test group. purified virions were examined under the electron microscope, the result revealed that there are a lot of virions and the aev - nh937 was multiplicated in embryos. the second part was seguence analysis of the genome of the aev - nh937. nine pairs of primers were designed according to published calnek vaccine strain of aev

    本研究共分四個部分：第一部分為aev的增殖，純化和電鏡觀察，用1 : 5倍稀釋的aev - nh937株和陰性對照pbs分別經卵黃囊接種於6dspf雞胚，繼續孵化10d后，收集尿囊液。比較接種組和健康對照組雞胚的大小，結果顯示，健康對照組雞胚明顯大於接種組。分離、提純aev ，把純化的病毒在電鏡下觀察，證明確有大量aev病毒粒子存在，說明aev在雞胚中成功擴增；第二部分是aev - nh937基因組的序列測定工作。
  2. Abstract : at first, the shaking table test of a gravity pier model was done. the comparison between the test data and the theoretical analysis results of the model showed that they are identical to each other. the dynamic model of a whole bridge with gravity piers and lead - rubber bearings was set up. the positive role of lead - rubber bearings on lowering the seismic responses of railway bridge and the seismic character of gravity piers were analysed. some earthquake resistance measures of railway bridge with gravity piers were put forward

    文摘:首先進行了重力式橋墩模型振動臺模擬地震試驗，試驗與理論分析結果基本一致;然後建立了採用鉛芯橡膠支座的重力式橋墩橋梁全橋體系動力分析模型，計算分析了鉛芯橡膠支座對橋梁的減、隔震作用及重力式橋墩的抗震性能，提出了重力式橋墩橋梁的抗震措施。

    本文用「前三階中心矩相等」法，提出了兩種新檢驗，分別用卡方統計量和f統計量去逼近（ f _ （ gls ） （ ） ） ，並與wu ， holt和holmes （ 1988 ）提出的修正f檢驗進行了比較。
  4. The technical and economic evaluation of thin - type spunbond nonwoven project has mainly finished the following research work : ( 1 ) utilize the theory and method of < marketing > for market investigation, research and forecast, analyze the developing trend and market requirement of the nonwocen abroad and at home, conduct quantitative forecast for raw materials and product price, and explain that during the essential period when liaoyang petrochemical company regulates the structure of industries and product and remodels the main business items, selecting to build up the production device for thin - type spunbond nonwoven is suitable. ( 2 ) introduce techniques of different companies to form different schemes. after analyzing the features of various schemes in the thesis, through building up the target system of four levels and utilize technical comprehensive evaluating way to conduct technical evaluation of four schemes for the thin - type spunbond nonwoven project and get the prior sequence from schemes d, b, a to c. ( 3 ) different technical schemes have various cash circulation amounts, economic evaluation is first based on evaluating and confirming feasibility of each scheme by the single scheme finance, select and use the method of multiple schemes comparison selecting - inutual repelling type multiple schemes optimization, select introducing the scheme of d company technique as the optimum, then conduct undetermined analysis to further test and verify feasibility of schemes
