Combined with present situation on overcurrent protection of low voltage electrified wire netting in mine,analysed several reasons on appeared mis-start or refuse-start of overcurrent protection in mine,thus provided some concrete arguments for research workers and users of overcurrent protection .

结合目前井下低压电网过流保护的现状，探讨了井下过流保护出现误动与拒动的诸多原因，以便给采用新原理的过流保护的研究者和改进现有过流保护的使用者提供一些具体的论据。

I don't, we don't have such a logic that in a cabinet if one member or several members have been studied in former Soviet Union or in any other countries, then this cabinet will be pro-Soviet Union or pro-any country.

钱其琛：钱其琛：任何一个内阁里面有人在前苏联留过学或者是在其他国家留过学，留过学或者是在其他国家留过学，就认为这个内阁一定是对哪个国家怎么样，这个内阁一定是对哪个国家怎么样，我看这个逻辑不存在。

Because of the off-phase motor running to recognize the harm caused by different fault in the implementation phase of the motor protection have had two different views: that the broken phase to the electrical damage caused by overheating point of view to the implementation of the motor overheating protection or inverse-time characteristics of overcurrent protection, thermal relays the resulting program, thermal resistance package with over-current fault protection program delay, and other programs; that the break caused by phase to the motor windings high-voltage breakdown back-EMF's view of Open-phase protection program to take instantaneous action, and some electronic-type protectors available.

由于对断相运行给电机造成的危害认识不同，因此在对电机实行断相保护时产生了两种不同的意见：认为断相给电机造成过热损坏的观点要对电机实行过热保护或过流反时限特性保护，由此产生了热继电器方案、热敏电阻方案、断相过流延时保护方案以及其他一些方案；认为断相给电机绕组造成高压反电势击穿的观点，对断相采取瞬时动作保护方案，于是一些电子式保护器问世。

In this dissertation, at first, the history and present situation of the research related to overheating is reviewed, and then the research works are carried out in following aspects the calculation of radiative properties of coal combustion, the solution of radiative transfer equation in absorbing-scattering media, the analyses of combined heat transfer processes in flue side, the computation method of steam temperature deviation of superheaters and reheaters and the inversion method of their wall metallic temperature in furnace, the numerical simulation of gas-solid two-phase flow, combustion and heat transfer in furnace, the measurement of outlet steam temperature of superheaters and reheaters, engineering reformation of overheating and optimum design of superheaters and reheaters, etc.

本文在综述了与过热器和再热器超温问题有关的研究历史与现状的基础上，在煤粉燃烧产物辐射特性的计算、含散射问题的辐射传递方程的求解、过热器和再热器烟气侧对流与辐射复合换热及汽温偏差的计算和炉内金属壁温的反演、炉内气固两相流动、燃烧、传热过程的数值模拟、过热器再热器炉外出口汽温的测量、过热器再热器超温问题的工程改造及设备的优化设计等方面进行了研究。

The dissertation presents somecontents about the vacuum precooling as follows: 1. Studies on the evaporation cooling principles of fruit and vegetable There are different optimal storing conditions for different vegetables and fruits.And the vegetable and fruit precooled by vacuum must be fit with the storingcondition. A low temperature will result in the frozen scald, and a high temperaturewill not meet the precooling objective.

本文开展了以下几个主要方面内容的研究：1、果蔬蒸发冷却规律的研究不同果蔬都有各自不同的最佳储藏条件，因此，真空冷却后的果蔬必须满足储藏要求，温度过低易引起果蔬冻伤，过高则达不到预冷的目的；湿度过低易引起干耗，减轻重量；过高则易引起腐烂变质。

Before that, he worked as a high school English teacher, an English teacher in Japan, a window cleaner, a car washer, a kitchen hand, and a furniture salesman.

在那以前，他曾在一所高中教过英文，在日本教过英文，做过蜘蛛人，洗车师傅，厨房的小工，还做过家具的销售人员。

Walked past the North-South ~~ drunk the water behind the toilet, the train aisle pressure off legs, but also, and too pro-fool mouth.

走过南~闯过北~厕所后面喝过水，火车道上压过腿，还和傻子亲过嘴。

It reminds you of a placid rivulet,meandering smoohtly through green pastures and shaded by pleasant trees,till at last it falls into the vasty sea, ball gown ;but the sea is so calm,so silent,so infifferent,that you are troubled suddently by a vague uneasiness.

它使人想起一条平静的溪流，蜿蜒畅游过绿茵的草场，浓荫遮蔽， cheap bridesmaid dresses ，最后注入烟波浩渺的汪洋大海；但是大海太过平静，太过沉默，太过不动声色，你会突然感到莫名的不安。

It reminds you of a placid rivulet, meandering smoothly through green pastures and shaded by pleasant trees, till at last if falls into the vasty sea; but the sea is so clam, so slient, so indifferent, that you are troubled suddently by a vague uneasiness.

它使人想起一条平静的溪流，蜿蜒畅游过绿茵的草场，浓荫遮蔽，最后注入烟波浩渺的汪洋大海；但是大海太过平静，太过沉默，太过不动声色，你会突然感到莫名的不安。

And you haven't lived until you have seen the dreamlike cloudscapes of Mount Huangshan, heard the thundering and pounding of the Three Parallel Rivers, breathed the fresh, moist air in Huanglong and Jiuzhaigou valleys, and experienced the moments of gusty winds whistling past the summit of Mount Everest.

穷尽一生，如果我们没有目睹过亦真亦幻的黄山云海，没有听到过三江并流的怒吼与咆哮，没有嗅到过黄龙与九寨的清新水气，没有感受过珠峰顶上雄风掠过的瞬间，生命是不是少了许多光彩？

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。
