    空氣節能熱水器是創新一代熱水設備，它成功地運用逆卡諾原理，用電能驅動熱泵，通過熱泵裝置中的構成部件-蒸發器，熱泵，冷凝器和膨脹閥，促使工質不斷完成蒸發（吸收空氣中的熱量）壓縮冷凝節流蒸發的熱力循環過程，從而環境的熱量轉移到水中，將空氣中大量免費的熱量轉移到生活中水中
  2. Motion control is a comprehensive subject. modern ac drive is a important embranchment in the field of motion control. however, it is difficult to rea1ize high - performance ac drive systems because induction motors are a kind of strongly - coupled nonlinear system with many variables and the torque is not easy to control. with vector control technology decoupling and torque control of ac motor are solved. the basic idea of vector control is that three - phase system is equiva1ent to two - phase system by coordinate transformation and it realizes the decoupling between field current and torque current of the stator in order to control the flux and current respectively, thus induction motor can be considered dc motor and high performance is achieved easily. with the progress of electric and electronic technology and the development of computer, high - integrated special modules and high - precision digital signal processor ( dsp ) are applied to ac drive so that vector control has been developed rapidly

    但是高性能的交流調速系統實現很困難，這是因為交流電機是多變量、強耦合的非線性系統，不易實現高性能轉矩控制。矢量控制技術則解決了交流電機解耦與轉矩控制問題，其基本思路? ?應用坐標變換將三相等效為二相，實現定子勵磁電流分量與轉矩電流分量之間的解耦，達到對交流電機磁鏈與電流分別控制的目的，交流電機等效為直流電機實現高性能調速。隨著電力電子技術的進步，計算機技術飛躍發展，高度集成的專用模塊和高精度的數字信號處理器應用於交流傳動系統中，促進矢量控制迅猛發展，日趨成熟。
  3. Based on the current helicopter operation at home and abroad on transmission line and its technical development trend, the paper has carried on research and demonstration on feasibility to apply helicopter in cruising inspection of yang - huai 500kv transmission line from various aspects as its significance, necessity, selection of operating management mode and technical working plan as well as its rationalization economically etc. applying helicopter to operate on power transmission has been tendency of the world power industry. on using helicopter to cruise, inspect and maintain the yang - huai 500kv transmission line, the first objective is to insist on flying safety. two steps should be taken seperately for short term and long term objective. first, to rent helicopters and then, to buy them

    採用直升機進行電力作業已經成為世界電力工業的潮流，應用直升機巡視和維護500千伏陽淮線，應堅持把安全飛行作為首要目標，宜分近期和遠期兩個目標分階段實施，先租機，再購機；直升機的選型，主要從安全性和經濟性兩方面考慮，在起步階段租賃bo - 105c直升機；要根據作業項目和方法選擇機載儀器設備；用直升機進行輸電線路巡檢，能極大地提高勞動生產率，具有明顯的經濟效益，並將提高我國直升機運用水平，促進我國通用航空事業的發展，從而帶動相關行業的發展。
