Actually , if we can look on activities of stock market as a series price competition and dealing process in a fixed system , then we can choose p / e as the process variable to study the venture of stock market with spc ( statistic process control ) theory 股票市场的运动演进可视为一个系统内的投资者连续竞价交易的过程,因此可选择表征股票市场的风险的市盈率作为过程变量,应用过程控制理论研究股票市场的风险。
Pointed out the problems after the open ringed servo electrical machinery system chooses pid algorithm , and concluded it into two points , firstly , the control transfer curve is not smooth , secondly , direct current servo ' s fix system can not reach its optimized point 摘要指出了开环伺服电机系统选择pid控制算法后存在的问题,概括为两点:其一是控制传递曲线不平滑;其二是直流伺服线性定常系统辨识不能达到最优值。
This paper focuses on the core part of the il & sm fixture system - information process system ( ips ) . after relevant information is obtained from the current part , ips designs the roughcast and the parameters of stuffing , matches or designs rational locating box , positions all the locating bolt , finishes the procedure of datum conversion and ensures the communications between state shaping system , part fixing system and nc programming system 本文的研究对象为il & sm夹具系统的核心部分? ?信息处理系统( informationprocessingsystem ? ips ) ,它通过获取零件的相关信息,进行毛坯与填料厚度的设计,设计或配置出合理的寻位箱,智能布置寻位元件,完成基准转换,并负责与状态成型系统、工件安装系统、 nc编程系统等模块的通讯。
