闸流管

Integrated gate commutated thyristors are the key components to assure reliable and efficient operation of high power inverters.

集成门极换流晶闸管是大容量变换器高效可靠运行的重要元件。

Gate commutated thyristor is a new high power semiconductor devices based on Gate turn-off thyristor, GCT has extensive application foreground and it is a blank in interiorly now.

门极换流晶闸管是在GTO的基础上开发的一种新型大功率半导体器件，有广阔应用的前景，目前在国内尚属空白。

Two PI adjustors were applied for wire feeding velocity control, one performed motor armature voltage feedback, the other one executed arc voltage feedback to determine the given velocity.3、 Exchanging data of power source and process controller by adapting 20mA current loop by a serial communication interface, which satisfy real time control demand.

该控制器具有焊接参数预置、记忆、锁定、数显以及自动引弧、收弧等功能。 2、焊接电源采用三相半控桥晶闸管整流电路，用不同方法计算偏差进行多变量数字解耦PI调节获得恒流、恒压、陡降和缓降四种输出静特性。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
