分断

The reason is that soonest at the next current zero-crossing the firing pulse of thyristors can be reset.

通常的短路故障电流会大大高于这个倍数，而软启动器的晶闸管本身是没有短路分断能力的。

Also, because a knife is equipped with fuses fused switch is closed packing tube fuse, it is also very high breaking capacity.

又由于刀熔开关所配备的熔断器是有填料的封闭管式熔断器，故分断能力也很高。

Select Fast Fuse breaking capacity in general do not have to do verification because the aR-type fuses rated breaking capacity of 50KA, NGT fast fuse breaking capacity of 120KA, able to meet the general power distribution engineering.

选用快速熔断器一般不用做分断能力校验，因为aR型熔断器的额定分断能力为50KA，NGT快速熔断器的分断能力为120KA，能够满足一般配电工程需要。

Hyphenate between sy-llables and avoid un-necessary hyphens.

以连字号断字换行，应在音节分断处，还要避免不必要的断字。

Using this model system, development of quadratic mean diameter, mean height, the number of surviving trees per hectare, stand basal area, and stand volume can be simulated for various levels of initial density and site.

采用该模型系统即可以模拟落叶松人工林不同林分条件下的林分平均胸径，平均树高，每公顷株数，林分断面积和林分蓄积量的生长过程。

CCF of control kept relatively stable, but that of thinning plots firstly decreased, then increased with ages and graduallyapproached to that of control. For Cunninghamia lanceolata plantation with different initial planting density, annual average growth rate of basal area and volume of low-density stands was more than that of high density.

对不同初植密度的人工杉木林分进行断面积和蓄积的研究，发现不同初植密度对杉木林分的断面积和蓄积的生长有一定的影响，初植密度大的林分断面积和蓄积年平均生长率要小于初植密度小的林分，说明初植密度小的林分有向初植密度大的林分渐近的趋势。

By comparing the breaking velocity and time between back-up releasor and electronic releaser,the back-up one can quickly break the circuit,shortening the breaking time.

通过后备脱扣器与电子脱扣器在分断速度与分断时间进行比较，提出了后备脱扣器可迅速分断电路，缩短分断时间。

When operating current of the main circuit rises over the setting value ILC1 and ILC2,connection signal will be sent out after time duration tC1 and t C2 separatively.

若分断此路负载后，主电路运行电流低于 ILC2且持续时间tc2 后，控制器可再发出信号，指令接通已分断负荷，恢复该负载供电。

The whole stand model system was set up for Larch plantation, which was composed of 5 models mentioned as follow and models were compatible each other: 1 stand ultimate self-thinning line and definition of SDI; 1 prediction model for trend of stand density index; 3 predicting model of height-diameter curve; 4 stand basal area growth model; 5 Schumacher's stand yield model.

以落叶松人工林林分断面积生长模型为核心的全林分模型系统，由满足相容性原则的5个模型所组成：1林分最大密度线及SDI的定义；2林分密度动态预估模型；3树高曲线动态预估模型；4林分断面积生长模型；1Schumacher式林分收获模型。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
