From the burden increased aspect clarify set up the necessity of station, then pass to drew up to set up generalize of transformer substation and line direction to consider, and pass to analysis of carry the data, safety, economic and dependable consider and made sure the 110 kV, 35 kV, 10 kV and station use electricity of lord connect line, then again through burden calculation and power supply scope made sure main number, capacity and model number of the transformer set, also in the meantime make sure the station uses capacity and model number of transformer, end, according to biggest keep on work electric current and short circuit calculating of calculation result, to the high pressure Rong break a machine, insulate a switch, female line, insulate son and wear a wall set tube, electric voltage with each other feeling machine, electric current with each other the feeling machine carried on choose a type, thus completed a 110 kV electricity a part of design.

本文首先根据任务书上所给系统与线路及所有负荷的参数，分析负荷发展趋势。从负荷增长方面阐明了建站的必要性，然后通过对拟建变电站的概括以及出线方向来考虑，并通过对负荷资料的分析，安全，经济及可靠性方面考虑，确定了110kV ，35kV ，10kV 以及站用电的主接线，然后又通过负荷计算及供电范围确定了主变压器台数，容量及型号，同时也确定了站用变压器的容量及型号，最后，根据最大持续工作电流及短路计算的计算结果，对高压熔断器，隔离开关，母线，绝缘子和穿墙套管，电压互感器，电流互感器进行了选型，然后进行配电装置和平面布置的设计以及防雷的设计，从而完成了110kV 电气一次部分的设计。

Regaining new stable equilibrium he rose uninjured though concussed by the impact, raised the latch of the area door by the exertion of force at its freely moving flange and by leverage of the first kind applied at its fulcrum, gained retarded access to the kitchen through the subadjacent scullery, ignited a lucifer match by friction, set free inflammable coal gas by turningon the ventcock, lit a high flame which, by regulating, he reduced to quiescent candescence and lit finally a portable candle.

30他重新获得了稳定均衡，尽管因猛烈撞击而受震荡，却没有负外伤就站了起来。他使劲扳院门搭扣的那个活动金属片，凭着加在这一支轴上的初级杠杆的作用，把搭扣摘开，穿过紧挨着厨房地下的碗碟洗涤槽，绕道走进厨房。他擦着了一根安全火柴，转动煤气开关，放出可燃性的煤气。他调节那燃旺了的火焰，捻小成发白的文火为止。最后，点上一支便于携带的蜡烛。

The switch of electromotion appliance should be designed to prevent actuation accidently, in order to ensure the safety of the user.

电动工具的开关应被设计成能阻止意外或不小心的触发，从而保护使用者的安全。

Underneath the center display are two movable climate control vents, the emergency flasher switch and a passenger-airbag off light.

该中心的显示下方有两个可移动的气候控制系统的通风口，紧急闪光器开关和一个乘客过轻安全气囊。

In the data acquisition system, CD4051 and AD574- the A/D transform, are used as hard core to receive the signal from the infra-red ray temperature sensor; the data acquisition depend on CPU; in the keyboard/ display system, a 74LS48 as the driver to drive LED works; in the warning circuit, I used two color LED and a buzzer as one unit to work; DAC0832 converter is the center of the D/A transform; execution unit, I used DDZIII type electromotive unit; the auto-man, it is a disabling of the other control circuit, this can secure production all the time.

在数据采集部分，以多路开关CD4051和AD574模/数转换器为核心接收来自红外线传感器的信号；数据处理依赖CPU；键盘/显示部分，以74LS48驱动LED数码管工作；报警单元，采用了双色LED加蜂鸣器的组合；D/A转换采用了DAC0832转换器；执行器采用DDZIII型电动执行器；手/自动切换装置则屏蔽了之前的电器部分，安全可靠。

The digital input can be used in conjunction with an external safety interlock switch.

数字输入可以和外部安全联锁开关联结在一起。

A knife switch with iron shell shall be installed in the power supply line, which is exclusively for this oven, and the outer plate shall be grounded for safety.

应在供电线路中安装铁壳的闸刀开关一只，供此箱专用，并将外壳接地。以保证使用安全。

If you take woodwork / metalwork / Design Technology or similar classes, have you seen over-ride switches or safety devices on equipment that are more difficult for a left-hander to use?

如果你把木工/金属/设计技术或类似的课程，你看到的预约开关或安全装置的设备，更难以对左撇子使用？

The modification includes a hazardous area motor and separate wall-mounted starter with intrinsically safe control circuit.

改装包括危险场所电机和带有本质安全回路的墙壁安装的启动开关。

An input phase voltage is divided into a main range and a transition range in which new P, M, N conditions and PM, NP, MN transition conditions are defined, some null vector is selected and the condition combination sequence of bidirectional power switches are adjusted in each modulation period to realize the safe, reliable and rapid commutation and the stable operation of the matrix converter.

本发明属于矩阵变换器控制技术，为一种用于矩阵变换器的控制方法，通过把输入相电压划分为主区间和过渡区间、在过渡区间定义新的P、M、N状态和PM、NP、MN暂态以及在每个调制周期内选择特定的零矢量并调整双向功率开关状态组合顺序，实现矩阵变换器安全、可靠、快速换流和稳定运行。

And Pharaoh spoke to Joseph, saying, Your father and your brothers have come to you.

47：5 法老对约瑟说，你父亲和你弟兄们到你这里来了。

Additionally, the approximate flattening of surface strip using lines linking midpoints on perpendicular lines between geodesic curves and the unconditional extreme value method are discussed.

提出了用测地线方程、曲面上两点间短程线来计算膜结构曲面测地线的方法，同时，采用测地线间垂线的中点连线和用无约束极值法进行空间条状曲面近似展开的分析。
