The electric drive system is made detachable for ease of transportation and installation . 为了便于运输和安装，电力驱动系做成可以拆卸的。
On a land vehicle the speed input is usually obtained from the speedometer drive system . 对地面运动体，输入速度通常由测速计的驱动系统来供给。
I had traced the cause of the trouble . one of the links in the chain that drives the wheels had snapped . 我找到了毛病的症结所在：驱动轮的链条断了一环。
Purkinje fibers are driven ("over driven") by the sinus node at twice their intrinsic rate . 浦氏纤维是被较其本身频率约高一倍的窦房结所驱动（“超速驱动”）。
Initially, clock-drivers were made from discrete components or special-driving integrated circuits . 最初，时钟驱动器是由分立元件或专用的集成驱动电路构成的。
When the liquid heights change, an "error" signal is produced and amplified to drive a servomotor . 当液柱高度变化时，产生一个“误差”信号，经放大后驱动伺服马达。
A second method, software-driven, but with the help of some additional hardware, is significantly faster . 第二种方法是软件驱动，但需要一些附加硬件。这种方法速度快得多。
If the orientations of driving elements are reversed then it is necessary to change a sign in their terminal relations . 如果驱动元素的定向取反了，就必须在它们的端子关系中改变符号。
In contrast, torque-feedback response for a two-axis gyro is decidedly affected by shutting off the spin motor . 相反，对于双轴陀螺，力矩反馈的响应是决定性的受到陀螺马达是否驱动影响的。
Driving power for the cutting tool comes from the rotation of the spindle, which is a hollow shaft that rotates in bearings . 刀具的驱动力来自主轴的旋转，主轴则是一根在轴承中旋转的空心轴。
