When PWRDWN is HIGH, the outputs switch in phase and frequency with CLK.

当PWRDWN为高电平时，输出开关和时钟频率的阶段。

If it is pressed down, pull up the emergency stop button by hands in a clockwise direction.

检查急停开关是否被按下，如按下则把它用手顺时针方向拔起来。

This paper features the work of rotating platform,to be adopted high-speed switching valve control system to control the rotating platform clockwise and counterclockwise rotation of the reciprocating movement.

本文针对旋转平台的工作特点，拟采用高速开关阀控系统来控制旋转平台的顺时针和逆时针的往复旋转运动。

The Clos Type network can satisfy this need quite well, so it is being used widely.

著名的 Clos- Type网 [3 ]能很好的满足这些要求，因此得到了广泛的研究 [4～ 9] 和应用，例如 NEC用于宽带ISDN的原子开关 [10 ]就是基于 3级 Clos- Type网，IBM的 SP2并行计算机的内部网络在功能上也等价于 Clos- Type网[11] 。

When the switch is on, the circuit is closed and electricity goes through.

当开关开着的时候，电路是闭合的，就通电。

With the control turned on, zero resistance or a closed circuit should be expected.

将冷冻开关打开，，就会显示0电阻或闭合电路的状况。

Once the switch is closed, the magnetic path has a lower reluctance.

一旦开关闭合，磁路则具有较低的磁阻。

The tenants have reflected this situation to the heating sector, staff Safety valves emergency examination revealed that 4 shortlisted cell thermal wells for heating pipe valve was closed, the switch handle is cut the same time, the well of the heating return pipe valve doors were also damaged, apparently caused by man-made.

住户们将这一情况反映给供暖部门，工作人员紧急检查发现，小区热力井里这4栋楼的暖气管道阀门被人关上后，开关手柄被砸断，同时井内的暖气回水管道阀门也遭到破坏，明显是人为所致。

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。

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。
