  1. In this thesis, first, reasons and factors for the stability of loose rock dams were summarized according to the field surveys and certain expert ' s experiences. then, researches on block stability problems were reviewed, and according to the relationship between grain size and incipient velocity, it is found that the block weight is in direct proportion to 6 - 9 power of incipient velocity, and 50 % increase of the velocity will result in about 40 times change of the block weight. after that, experiments were conducted in a flume, focusing on the relationship between incipient velocity and some main factors including block weight, water depth over the dam, cross - section size, block material and river bed material

    本文首先根據散拋石壩損毀情況的現場調查資料，結合有關專家多年的整治經驗，總結出壩體的損毀原因及影響因素；對現有塊體穩定性的研究成果進行回顧和總結，並針對散拋石壩的直接損毀現象，結合山區河流的水流、地形特點，利用塊體粒徑與起動流速的關系，提出塊體穩定重量與起動流速高次方成正比的概念，流速50的增長可能導致塊體穩定重量接近40倍的變化；通過二維變坡水槽試驗，研究了壩體穩定的主要影響因素，包括塊體重量、壩頂水深、斷面尺寸、塊體材料（塊石和卵石兩種） 、護底等，結果表明對于山區河流，試圖僅僅通過增加壩體單個塊體重量或斷面尺寸來提高壩體穩定性效果甚微；最後，根據西部地區的自然、經濟、交通等條件，提出可以採用柔性混凝土鉸鏈體等一類整體性較好的護面層作為散拋石壩的防沖毀措施，以期取得良好的工程效果。
  2. In this paper, the fundamentals of cable forces by frequency method are introduced. the curve fitting method is utilized to get the correcting formula of cable forces and frequency through the experiment. on the other hand, a kind of catenary line cable element is introduced in this paper, owing to the inaccuracy caused by correcting struss element in fem

    本文還介紹了頻率法測索力的基本原理，並通過試驗，利用曲線擬合法得出索力頻率之間的修正關系式；其次，由於有限元計算中，索元所採用的修正桿元所帶來的不精確性，對于長索其精度更難保證，因此，本文介紹了一種計算精度高、工作量小的懸鏈線索元。
  3. The high specificity of dot - ppa - elisa was proved by the specific blocking test, and also by the cross - reaction test in which the diaphragm did n ' t react with the antibodies against pasteurellosis, streptococcosis, colibacillosis, chlamydiosis, hcv, ppv, brucellosis, prv and foot - mouth disease. the diaphragm has good sensitivity and could detect some salmonella - positive test serum which has been diluted to 1 : 2048. stored at 4 for at least 6 months or at 10 - 25 " c for 4 months, the sensitivity and specif icity of the diaphragm did n ' t change, so it has good stability

    本研究制備的診斷膜片特異性強：不與豬衣原體病、豬口蹄疫病、豬大腸桿菌病、豬布氏桿菌病、豬瘟、豬偽狂犬病、豬細小病毒病、豬巴氏桿菌病、豬鏈球菌病的陽性血清發生交叉反應；診斷膜片具有良好的敏感性，能夠檢測到1 ： 2048稀釋的動物試驗陽性血清；膜片的保存期長，在10 25可保存4個月、 4條件下至少可保存6個月其靈敏度不變。
