测量与控制

The system,mainly controlled by the minimum system which consists of the single-chip microcomputer and FPGA,is designed based on the basic principles of digital oscilloscope,which achieves the function of the measured signal's sampling,storages and playbacks of the ordinary oscilloscope,adds the equivalent sampling and sample-and-hold function,which greatly improves the measurement range of the system.

基于数字示波器的基本原理，以单片机和FPGA组成的最小系统为控制核心，实现了普通示波器对被测信号的采样、存储与回放，并且增加了等效采样和采样保持功能，极大地提高了系统的测量范围。

Roll wear is a factor difficult to determine and there is no suitable theoretical model till now In this paper,the theoretical model of roll wear is established from the view of tribology,and the roll wear on finishing train of 2050 CVC hot strip mill has been measured The calculated results agree well with the measured,so the model for roll wear is of important significance for shape control

轧辊磨损是当前生产中难以定量确定的因素，磨损预报至今尚无精确的理论模型可利用。本文从摩擦学原理出发建立了轧辊磨损的理论模型，并对宝钢 2 0 5 0 CVC热连轧机精轧机组的轧辊磨损量进行实际测量，计算结果与实测值吻合较好，对提高磨损预报精度、提高板形控制技术水平具有重要意义

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
