Our proxy product includes: SEMKRON; SIEMENS; SanKen; SANRex; FUJI; TOSHIBA; MITSUBISHI; Eupec; HITACHI; IXYS; IR; NIPPON; VICOR; LAMBDA; And so on the overseas well-known company produces GTR, IGBT, IPM,PIM, the silicon-controlled rectifier, the crystal thyratron, quicklyrestore the diode, the rectification bridge.

我们的代理产品有：三菱、三社、三垦、富士、东芝、西门子、西门康、摩托罗拉、IR、EUPEC、IXYS等国外知名公司生产的GTR、IGBT、IPM、PIM、可控硅、晶闸管、快恢复二极管、整流桥。

We can see that the equivalent of two transistors GTO current amplification coefficient ratio α2/α1 than regular thyristor large.

而GTO在设计时使α1+α2≈1.05，给门极控制关断提供了有利条件。可以看出，GTO的两个等效晶体管电流放大系数之比α2/α1比普通晶闸管的大。

It is shown that the maximum controllable current depends on the design of the current gain and emitter-shorted current.

结果表明，耦合晶体管电流放大系数及晶闸管射极短路电流的设计决定了器件的最大可关断电流。

As the ball valve open and close easily than the current pipeline and meter connections are also most of the use of ball valves.

由于球阀启闭比闸阀方便，目前管道和水表的连接也大部分采用球阀。

With control transistors cuntin horn ,Stove controller cutin voltage. So that controles stove of temperature.

通过控制晶闸管的导通角，来控制电炉两端的有效电压值，从而控制电炉的温度。

Through the simulation, the volume distributions, velocity, pressure and hydrodynamic loads on cylinder gate for some instances are obtained. The calculated result is in good agreement with experimental data.

通过数值模拟，得到不同时刻计算域内的相体积分布、圆筒闸体附近速度场、压力场以及各工况的荷载，并与模型试验实测结果进行对比分析，两者吻合较好。

The Company are the production and sale of concrete pump, pump fittings Professional manufacturer, has 31 major products, in conjunction, Chutian various brands and specifications of the concrete cylinder, master cylinder, swing cylinder, gate valves, etc..

本公司是生产和销售混凝土输送泵、泵车配件专业厂家，主要产品有三一、中联、楚天等各种品牌和规格的砼缸、主油缸、摆动油缸、闸板阀等。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
