adj.双速的
The operational principle of VR two speed resolver is based on permeance variation in airgap so that the voltage in output winding vary with the position of rotor is induced. 磁阻式多极旋转变压器的工作原理是基于依转子位置而变化的气隙磁导与输出绕组电压成一定比例关系。
These method can be described below: directly withdraw annex rotates , withdraw annex rotates by ramp ,current memory by using two speed controller. 通过对动态速降的研究,提出了几种解决动态速降的方法,分别是附加速度直接去掉法、附加速度斜率去掉法、用速度环双调节器的电流记忆法。
One kiln,two belts with two speeds which is adjustable. 一台炉两条网带，两种速度，速度可调。
Because the operational principle of the VR resolver is different from that of the conventional construction two speed resolver, the cause producing the error is also different. 由于其工作原理与传统结构多极旋转变压器不同，产生误差机理亦不相同。
Transmission, built in the top drive power head, has two speed range? High and low. It can meet the requirements of both DTH hammer drilling and carbide bit drilling. 动力头设有变速装置,有高低两个档次,以满足潜孔锤钻进及硬质合金回转钻进方法。
Because the operational principle of the VR resolver is different from that of the conventional construction two speed resolver,the cause producing the error is also different. 由于其工作原理与传统结构多极旋转变压器不同，产生误差机理亦不相同。
