On the basis of finite element numerical simulation technology and s - n curve data base of welded joint, the course of fatigue test of physical prototype was simulated with computer and the fatigue life of welded structure was predicted, so as to let the development of anti - fatigue design becoming possible in the designing stage of product
基於有限元數值模擬技術及焊接接頭s - n曲線數據庫，在計算機中模擬物理樣機的疲勞試驗過程，預測焊接結構的疲勞壽命，使產品在設計階段開展抗疲勞設計成為可能。 -
On the base of the data, itgices some useful design plans to reinforce the coast. then it generally analysis and evaluates the construction measures of the coast. at last this article analysis the sensitivity of different kinds of rock and soil, and researches the theory of physical destroy of the road entrenchment coast. the method which is given in the article is useful to the similar coast
文中還對滑坡體各類巖土參數進行了敏感性分析，並對張清公路路塹滑坡力學破壞機制進行了重點研究。本文提出的滑坡治理設計方法對治理類似滑坡有指導作用。 -
After deeply studying all kinds of problems of current actualization methods, we put forward to a new actualization method of the technology of physical isolation on the base of cpld. we make a lot of research on data encryption and describe the design method of the encryption chip on the base of lfsr ( linear feedback shift register ). after putting forward to the whole design procedure, we design an encryption chip on the base of lfsr, which can provide the high - quantity data stream of encrtption
在深入研究了常見物理隔離技術實現方案中存在的各種問題后，提出了一種基於cpld的全新實現方案；同時，對于存儲信息的加密也進行了研究，詳細闡述了基於移位寄存器的非線性組合序列密碼的設計方法，提出了完整的設計流程，並設計了一個基於fpga的非線性組合反饋序列密碼晶元，該晶元能提供高質量的偽隨機密鑰流。
