single-throw contact

Test plate method belongs to contact-type detection, is easy to cause secondary damage of the surface shape. Interferometer method belongs to non-contact, but it usually detects single-chip and costly.

样板法属于接触性检验，容易对面形造成二次损伤；干涉仪法属于非接触法，但干涉仪造价昂贵，而且通常只能对单个镜片进行检验。

Normally Single Row Angular Contact Ball Bearings are used a combination of two or more bearings.

通常情况下单列角接触球轴承的用途是两个或两个以上的轴承组合.

The models of total contact time and single contact time aiming at the pan rotary dryer and tube rotary dryer are set up.

提出了间接式干燥机内物料与干燥机加热壁面总接触时间的计算方法模型，并提出了针对旋转圆盘式干燥机和旋转列管式干燥机的每一个理想接触过程的接触时间计算模型；

All vocal polyps with wide bases either single or bilateral, had increased CQ and F 0, the main abnormalities were steep in contact opening phase and flat in wave peak.

单或双侧广基息肉使CQ及F0升高，电声门图分别以接触开放相陡直和波峰平坦为主。

A novel over-load relay realized by low-waste single-chip microcomputer is introduced, here are some charac ˉ teristic such as dispense with additional power supply, using no-contact SCR.

介绍了一种用低功耗单片机实现的新型电机过载继电器，其无需外加工作电源，采用无触点晶闸管输出。

Based on the G-W contact model and Hertz theory, the contact status between polishing pad and wafer is analyzed at first. A mathematic model of material removal in polishing is obtained by means of the grinding action of single abrasive.
