Connected with the practice of design on the integrated wiring system, this thesis will discuss three problems : the difference between frequency bandwidth and transmitted velocity, the selection of shield and non shield twisted pair, the design of systematical protection on electricity. 结合综合布线系统设计实践,论述了频率带宽与传输速率的区别,屏蔽与非屏蔽双绞线的选择及系统电气防护设计三个问题。
The mill, consists of a 18-stands mill, 8-pass non - twisted block mill and a 4-pass sizing mill. 生产线由18架轧机、8道次无扭线材轧机和4道次定径机组成。
Chinese stock market possesses the systematical defects with its birth, the existence of a large number of non - negotiable stocks make the Chinese stock market be strongly twisted. 中国股市具有与生俱来的制度性缺陷,大量非流通股的存在使中国证券市场被强烈扭曲。
