Within the limits of puc the combined demographic social and economic forces give rise to hyper speed urbanization at an unseen scale 在中國人民的城市之中,人口統(tǒng)計結合社會與經(jīng)濟的力量使得的城市化進程在一個不被人所見的規(guī)模下迅猛發(fā)展。
Especially , with the requirement of the digital controlled machine tools increasing , the hyper speed , the hyper precision , the hyper reactivity , what is called zero mechanical gearing control theory , are easy to put in practice for the linear motor ' s servo system 特別是隨著數(shù)控機床加工技術要求不斷地實現(xiàn)高速和超高速化、精密和超精度化,高速反應能力地直線伺服進給技術一所謂地零傳動方式便應用而生。
