输入功率

A cluster of metal steam above welding pool and its obvious effect on reducing the laser energy input was found by real time image sensing. Side-blowing shield gas could remove the metal steam, and the effective power of the laser was elevated.

通过实时的图像采集，观察到熔池表面存在的团状金属蒸气，其对激光能量的输入造成较大影响，通过侧吹气体可以将其去除，提高激光有效功率。

The weight coefficient determined by peak frequency in power spectrum is employed to evaluate its smooth-going characteristic. And about SF32601's handle stability, the following six aspects are considered: the steady and transient respond characteristic of the redirector under steps input; the straight performance to go back; the angular speed frequency respond characteristic of balance weight; the steering performance under typical operating mode and Straight line mode.

用功率谱密度中峰值频率所给定的加权系数对其平顺性进行了校核并从转向盘角阶跃输入下稳瞬态响应特性、转向回正性能、横摆角速度频率响应特性、典型工况行驶性能和直线行驶能力六方面对其操纵稳定性进行了研究。

Then, flaw of existing full-digital voltage commutation method is pointed out after the change of the critical area which switch sequence will encounter corresponding to the variety of displacement angle at the input-side of converter has been explicated, then several rules have been presented and used to instruct detailed voltage commutati.

通过分析输入侧功率角变化对矩阵变换器全数字电压换流技术的影响，指出现有全数字化电压换流方案的缺陷，并提出新的改进原则，接着给出详细的数字化电压换流策略实现方法，分析新方法对变换器换流次数的影响。

Then, flaw of existing full-digital voltage commutation method is pointed out after the change of the critical area which switch sequence will encounter corresponding to the variety of displacement angle at the input-side of converter has been explicated, then several rules have been presented and used to instruct detailed voltage commutation method built. Increment of switches' commutation-times, thanks to the new method employed, is analyzed in succession.

If so, the following three conditions are not caused by outside: Enter the loop by a diode bridge rectifier breakdown; high-voltage electrolytic filter capacitor C5, C6 was the breakdown; inverter power switch Ql, Q2 damage.

若是，则不外如下三种情况造成：输入回路中某个桥式整流二极管被击穿；高压滤波电解电容C5、C6被击穿。；逆变功率开关管Ql、Q2损坏。

A television or FM broadcast station, operating at relatively low power that receives a distant input signal, amplifies it, and retransmits it on the same channel.

电视或调频广播站，功率相对较低，接收到一个远端输入信号，进行放大，然后在相同的信道上将放大后的信号再发射出去。

Finally, according to market conditions and market products this article paper analyzes the trends in the development of camera technology, and designs a color night vision camera.

最后根据市场情况和市面上产品的情况分析了摄像机技术的发展趋势，并设计了一款彩色夜视摄像机。

Only person height weeds and the fierce looks stone idles were there.

只有半人深的荒草和龇牙咧嘴的神像。
