Electrical power on the back panel is not "on", please open "on" state.

后面板电源键没有打在"ON"状态，请把电源键打在"ON"状态。

This paper studies the electrode combination of 3D tunnel DC focused method. At first, the authors calculate and analyze the current distribution of two point power sources with the same electrical property, and indicate that as currents exclude each other, current density has a maximum at a certain depth along the perpendicular bisector of the two point power sources and the depth is directly proportional to the distance between them.

本文研究了三维坑道直流聚焦法电极组合，首先计算分析了两个同性点电源的电流分布规律，指出由于电流的相互排斥作用，电流密度在这两个点电源的中垂线下一定深度处产生最大值，这个深度与这两个点源之间的距离成正比。

Bistable circuit is the active devices need power to work, as long as the power supply normal, long-term stability can save information, so called static memory.

双稳态电路是有源器件，需要电源才能工作，只要电源正常，就能长期稳定的保存信息，所以称为静态存储器。

Of the development as new and high technology and equipment of solar energy form a complete set perfect, solar energy power source regards a country as bourg eventually with power source of provide for oneself gumshoe entered an innumberable families.

随着高新技术的发展和太阳能配套设备的完善，太阳能电源终于作为农村村镇和家庭的自备电源而静静走进了千家万户。

These units can be recharged by plugging them into a USB port, household outlet, vehicle DC outlet or by using Brunton's solar panels.

这些单位可充电插入到USB端口，家用电源插座，汽车直流电源，或使用顿的太阳能电池板。

The television power supply demands low ripple voltage, and the passive RC buffer circuit used in television before, decreased the power effect.

电视机电源要求非常低的纹波电压，过去电视机所采用的是大的无源RC缓冲电路，使电视机的电源效率比较低下。

Electronic equipment produces busywork and harmonic components that not only increase unnecessary loading and power consumption in public power equipment. But also harmonic components insert into public power system that causes deteriorating of power quality. Risks increase into break and mistake of precision instrument.

而电力设备所产生的虚功与谐波不仅无谓的加重公用电源设备的负担，增加无谓的功率消耗，更因为谐波成份的加入而使得电源品质恶化，增加精密设备损坏与误动作的风险。

The main woks include the design of charger, control and main circuit of inverse change, framing the circuit and calculating the related parameters.

本文首先介绍了小灵通机站长延时不间断电源的构成和后备式不间断电源的现状及其发展的趋势，并对小灵通UPS的要求及其技术指标进行了综述。

The basic concept and modeling of PDS are firstly narrated, then the method of calculating target impedance of a circuit PDS is introduced. At last a simulating and analyzing method using SPECCTRA Quest PI is put forward to verify the PDS.

结合PDS在不同频率时存在不同的输入阻抗，介绍了如何计算电源分配系统目标阻抗的方法，通过SPEC-CTRA Quest Power Integrity软件对电路的电源分配系统目标阻抗进行了仿真与分析。

This can also be divided into two categories: one is to discuss the influence of power factor by way of dividing power circuit into capacitive and emotional under the circumstance of unchangeable voltage and frequency of output power, and the other is discussed the influence from voltage and frequency of power to power factor with the situation of constant component parameters.

具体又分为两种情况：一种是在电源的输出电压和频率都不变的条件下，把电路分为容性和感性，讨论了元件参数对功率因数的影响，另一种是讨论了在元件参数不变的条件下，电源的频率和电压对功率因数的影响。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。

Galvanizes steel pallet is mainly export which suits standard packing of European Union, the North America. galvanizes steel pallet is suitable to heavy rack. Pallet surface can design plate type, corrugated and the gap form, satisfies the different requirements.

镀锌钢托盘多用于出口，替代木托盘，免薰蒸，符合欧盟、北美各国对出口货物包装材料的法令要求；喷涂钢托盘适用于重载上货架之用，托盘表面根据需要制作成平板状、波纹状及间隔形式，满足不同的使用要求。
