First of all, the paper analyses the compositive framework of electronic commerce system ; and analyses the characteristic of enterprise applications integration ( eat ) and business to business commerce ( b2b ) applications integration, and points out that b2b applications integration is under a condition of no uniform reference point, dynamic and incompact, restricted bandwidth, however eai is contrariwise, so we say b2b applications integration is very hard
本論文首先分析電子商務系統的集成框架，闡述了電子商務系統與企業內部信息系統的集成關系；分析企業應用集成（ eai ）和企業間電子商務（ b2b ）集成的集成特點和難度，指出企業應用集成是在統一控制下的緊密集成，而企業間電子商務集成則是沒有統一控制點、動態松偶合、有限帶寬的集成，因而集成難度較大。 -
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。 -
The reasons of the signal distortion are analyzed, and the relations of receiving bandwidth with distortion degree is discussed, for the more a steady point in the amplitude modulation signal is given by the method of the statistics. looking at the point as the timing reference point of the receiver, the stability of the receiver is less than 100us
分析了接收信號失真和受干擾的原因所在，論述了接收帶寬和失真程度的關系，並在此基礎上，利用統計的方法在調幅信號的下降沿上找到了一個較為穩定的特徵點，將其作為接收機的定時參考點，定時不確定度可以達到數十微秒量級。 -
The efficiency of the controller can be 36. 36 % or 72. 73 % when data length is 1 or 2. when the data length is 4 or above, the efficiency can be 100 %. the effect that on - chip cache has on memory bandwidth is analyzed, and an on - chip cache scheme that can reduce 50 % reference data read
通過多體交錯式存取，本文設計的ddrsdram控制器在存取數據長度為1或2個字時，帶寬利用率分別為36 . 36 %和72 . 73 % ，存取數據長度為4個字時，帶寬利用率可達到100 % ，滿足了高清實時解碼的要求。 -
( 2 ) the serious recording limitations due to the finite size and resolution of ccd are discussed detailedly. it ' s shown that the setup for recording hologram with spherical reference wave can make full use of the spatial bandwidth of ccd
（ 2 ）著重討論了ccd參數對記錄條件的限制，給出了數字全息術所能記錄的物體的最大尺寸與記錄距離之間的關系，指出用球面參考光波記錄全息圖可以更為有效地利用ccd的有限帶寬。
