  1. The control tactics of space voltage vector are investigated, and the simplified algorithm which judges the sector location of reference vector and calculates switch operation time is put forward. by analyzing the current hysteresis control, the relation between switch frequency, and hysteresis bandwidth and input inductance of pwm rectifier is deduced. by applying instantaneous power theory, the principle of pwm rectifier power control is analyzed, and the direct power control by matlab toolbox through estimating active power and reactive power with virtual flux is realized, and the simulation results prove that it is correct

    對常用空間電壓矢量控制策略進行分析，提出了給定參考矢量所在區間判斷的簡化方法，以及電壓矢量作用時間的求取方法；分析了電流滯環控制策略，推導出開關頻率與滯環帶寬以及整流器輸入電感之間的關系；應用瞬時功率理論分析pwm整流器功率控制原理，通過虛擬磁鏈估計有功功率和無功功率，用matlab實現了直接功率控制，並驗證了該控制方法的正確性。
  2. This paper has proposed one new way of thought of differentiating the fault type. after observing the physical course of the single - phase grounding of transmission line, analyzing by the wavelet transformation the transient signals sampled during the fault period from the moment that single - phased grounding occurs to the moment that line breakers work, we can distinguish temporary fault from permanent one through the wave form

    本文提出了一種不同於現有故障類型判別的思路，通過考察線路單相接地故障的物理過程，利用小波變換理論分析處理線路單相瞬時性故障和永久性故障在故障發生后斷路器開斷前時間段的暫態信號，通過波形識別區分兩種故障。
  3. But technology is usually a two - side sword, web media brings the human being much benefit ; at the same tune, it seems as if opening the padola box, its " negative effect is obvious : the direct of the public opinon is not clear ; the deed of violating power off often happens ; fictitious news and fithy information are flooding. information trans ceding the region and the national boundaries makes the opion of ethics between the west and the east communicate and collide. at the same time, international media produces a new monopoly

    但是，技術從來都是一把「雙刃劍」 ，網路傳播在給人類生活帶來巨大便利的同時，也如同打開了潘多拉的盒子，其負面影響日益顯著：輿論導向模糊；侵權行為頻繁發生；虛假新聞和色情信息泛濫；信息的超地域、超國界流動使得東、西方倫理觀遭遇空前的交流和沖撞，國際傳播產生新的壟斷… …網路技術飛速發展和信息流動的瞬息萬變使得上述倫理沖突幾乎是在一夜之間凸現出來。
