With the help of the electronic computers , engineers employ it to figure out nearly all kinds of engineering problems ranging from astronavigation , construction , waterpower projects , ship - building and mechanical engineering etc . owing to the strong power of finite element method , one kind of software pack which based on the method is exploited and named algor feas to resolve problems on structure analysis for trusses and shells . this paper also employ algor feas software pack to analyze and compute the cableway towers , giving the accurate result on stress and displacement both in location and whole . finally , we also bring out some advice on structure improving 在此分析過程中：首先將物理模型簡化為力學模型，主要是將塔架結構按空間桿單元簡化為空間桁架結構，目的是將力學模型變換為數學模型；這一過程主要是利用autocad2000建立塔架的計算模型；再者，利用algorfeas軟件包讀入autocad建立的塔架計算模型生成初始數據卡利用計算機進行編程進行風載計算，再將計算結論整合入algorfeas產生的初始數據卡中，生成計算數據卡；接著，利用algorfeas軟件包計算塔架在不同載荷情況下的應力圖，位移圖，并且求出在不同載荷條件下的最大位移和最大應力等；然后，對塔架的穩定性進行分析；最后；根據計算結果提出改進建議。
Single crystal silicon is the semiconductor material which is used mostly in the present electronic industry , it play a very important role in the field of aviation - astronavigation , optics , electron and micro - electronics 單晶硅材料是當代電子工業中應用最多的半導體材料,它在航空航天、光學、電子和微電子等領域發揮著十分重要的作用。
Professional astronaut besides should operate in astronavigation drive spacecraft , arrive even outside cabin execute a few special missions , if have outer space , walk , discharge or repair a satellite to wait 職業宇航員除了要在宇宙航行中操縱駕駛宇宙飛船，還要到艙外執行一些非凡的任務，如進行太空行走、施放或修理衛星等。
Titanium and titanium alloys have excellent specific strength and corrosion resisting property , and have important role in application in astronavigation facility , navigation facility , chemical industry and oil industry 摘要鈦及鈦合金具有優良的比強度和耐蝕性，在航天航空及石油化工行業中起著重要作用。
Given the abilities of generating all kinds of ideal and not ideal signals , it has been widely used in the domains of communication , radar , navigation and astronavigation 它可以產生各種理想及非理想的波形信號,是電子工程師、生產線以及教學科研的重要測試設備,廣泛用于通信、雷達、導航、宇航等領域。
Turntables are widely used in navigation , astronavigation and weapons , which have various types and usage 轉臺廣泛應用于航空、航天、兵器、航海等領域,有各種不同的類型和用途。
