本文闡述了研究礦山壓氣系統的意義和壓氣管網計算的基本理論及優化原理，並運用運籌學的分析方法，對雲南錫業集團公司老廠錫礦壓氣系統的現狀進行了詳細的調查研究。針對目前老廠錫礦壓氣系統存在的管網長、漏氣多、壓力損失大等主要問題，採用「圖論」中最小樹原理，對壓氣管網進行了優化研究。With the elimination of twiddling hempen threads by hand, masidun is disappearing gradually because of aging and being destroyed
但隨著手工績麻的淘汰，麻絲墩正在逐漸老化、損毀和消失。Several materials with large coefficient of expansion were selected to make packaging components, and it was found that the packaging materials have good temperature sensitivity and compatibility with optical fibers. experimental accuracy and repetition of fbg temperature sensitivity and compensation were discussed. have selected several materials which has bigger coefficient of expansion to do packaging components, have made many temperature experiments, there have not flaws, such as aging, crackle, absciss layer, packaging materials have good temperature sensitivity and compatibility with optical fiber ; have designed the simple and practical packaging components, have performed a serials of experiments about accuracy and repetition of fbg wave - length, have obtained the first step conclusion ; have analyzed the result and made comparison between the result of different experiment, have summarized the best packaging effect and several rules to reduce mistskes
本文所做的主要工作包括以下幾個內容：一、選取了常見的熱膨脹系數大的材料製作封裝元件，經過多次一80到80反復測試，封裝元件沒有出現老化開裂、封裝裂紋、空洞、離層等缺陷，封裝材料具有良好的溫敏穩定性及復用性，與光纖相容性較好；二、對光纖光柵進行簡單、實用的封裝處理，就封裝效果的優劣性、波長測量的準確度、重復性和封裝時產生的波長損失等方面進行了一系列的實驗，得出了初步的結論；三、對溫敏和溫度補償式封裝的實驗數據進行了詳細的分析和對比，從數字上對溫變過程中光纖光柵中心波長的改變及溫變曲線進行了定量的分析，在大量實驗數據分析結果的基礎上，總結出哪種材料封裝效果更好，以及如何有效的減小實驗誤差。And reached the following specific conclusions : rubber content with the increase of resistance to ageing rubber modified asphalt increased ageing after less than for low - temperature service, the quality of reduced losses, soften point increase needle into a normal degree. summed up the aging asphalt and modified asphalt laws made spent rubber for asphalt modified agents, the principles of the size options and dosage of rubber powder for spent rubber modified asphalt road asphalt in the application provided a good technical support
得出了隨膠粉含量的增加膠粉改性瀝青的抗老化性能提高，老化后低溫延度比減小、質量損失量減小、軟化點提高，針入度呈正態分佈及改性瀝青老化的規律，提出了廢膠粉用作瀝青改性劑時粒徑選擇和摻量確定的原則，為廢膠粉改性瀝青在公路瀝青路面中的應用提供了良好的技術支持。Undoubtedly, deterioration and damage accumulation occur in high temperature and high pressure. with the consumption of their use, the failure accidents occur more frequently, which will bring threatening to the life of people and the poverties of enterprise. so the failure analysis and the residual life assessment of the main steam pipe become more and more urgent and important
以蠕變性能作為設計指標的主蒸汽管道是發電廠的關鍵部件，由於長期在高溫高壓的惡劣工況下運行，容易發生材質老化和損傷積累，突發性事故也會頻頻發生，給企業職工的生命安全和國家財產帶來嚴重威脅，因此對主蒸汽管道進行失效分析與壽命預測尤為迫切和重要。Standard test method for effects of heat aging on weight loss, cracking, and chalking of elastomeric sealants
