tap-field control

The control proves to be mechanically strong and rigid by testing, and a hand electric drill equipped with it can be used as motordriven tap, wrench, screwdriver, etc.

经测试，机械特性硬，手电钻配上此控制器后，能作电动攻丝、板手、螺丝刀等作业，实现一机多用。

The easy JTAG is introduced to control Test Access Port ( TAP) by computer parallel port.

采用简易JTAG接口，通过计算机并口控制测试访问端口。

This finding extends the well-known power of music to tap into brain circuits controlling emotion and movement, to actually control the brain circuitry of sensory perception.

这一发现把音乐的力量从人们熟知的可以进入大脑回路从而控制人的情绪和动作延伸到实际可以控制感官知觉的大脑回路。

A unified pattern to transform three kinds of control variables, i.e., reactive power compensation, transformer tap and nodal voltage of generator, into integer variables is also presented.

提出了将无功补偿容量、变压器主变抽头和发电机节点电压3种类型的控制变量采用统一模式转化成整型变量的方法。

For substations, reactive voltage control is to guarantee volage quality and reduce active power loss of power system by adjusting the tap changer of transformer and devoting or removing some compensators of reactive power, which can make the powe system operate economically and safely.

对于变电站来说电压无功控制就是通过调节可调变压器的分接头和投切一定量的无功补偿设备以保证电网电压质量和降低电网的有功损耗，达到电网安全经济运行的目的。
