The dilute solution of the absorption apparatus of the refrigeration system serially backflows to the low, middle and high temperature solution heat exchangers and generators in turn and reflows to the absorption apparatus finally, thereby achieving the reasonable utilization of different grade energy and having relative high thermal efficiency of the unit.

该制冷系统吸收器的稀溶液串联倒流依次进入低、中、高温溶液热交换器和发生器，最后流回吸收器，能够实现对不同品位能量的合理利用，其机组热效率也相对较高。

Today, the two standard frequencies for generation, transmission, and distribution of electric power in the world are 60 Hz (in the United States, Canada, Japan, Brazil) and 50 Hz ( in Europe, the former Soviet republics, South America except Brazil, India, also Japan). The advantage of 60-Hz systems is that generators, motors, and transformers in these systems are generally smaller than 50-hz equipment with the same ratings. The advantage of 50-Hz systems is that transmission lines and transformers have smaller reactances at 50 Hz than at 60 Hz.

今天，60Hz(在美国，加拿大，日本和巴西使用)和50Hz(在欧洲，前苏联，除巴西以外的南美洲，印度以及日本使用)是世界上发电，输电和配电的两个标准频率。60Hz系统的优点在于系统中的发电机，电动机和变压器通常比同等级50Hz系统的设备小。50Hz系统的优点是传输线和变压器的电抗在50Hz时较60Hz时小。

The probability of injecting cold water into the steam generators in operation in the internal structures and connected pipings to prevent thermal shock or fatigue should be reduced by considerations in design.

应该在设计时考虑并降低在蒸气发生器中注入冷水使内部构造和相连管道运转以防止热冲击或材料腐朽的可能性。

"After practical generators were devised in the 19th century, many experimenters applied electric power to tube s of gas."

19世纪做出实用的发电机后，许多实验者对气体管施加电功率。

The use wood gas generators need not be limited to transportation applications.

使用木材气体发生器不必局限于运输应用。

RCSC has appealed within China for donations and supply of tents, 20KW and 40KW diesel oil generators, winter quilts and clothes.

中国红十字会已经开始呼吁捐赠和提供帐篷、20千瓦和40千瓦柴油发动机、棉被和衣服。

In addition, the region has introduced some 700 wind-driven generators.

使用这些无污染能源对保护环境起到了重要作用。

It is based on the experiment and research of Wind Wheel series of the Wind Generator which is provided by the financial aid of National Natural Science Foundation.[Approval number: 59776033], which is a basal experimental study for the questions existed in wind rotor blade of MW wind generators in China.

以国家自然科学基金资助项目《风力发电机风轮系列化的实验与研究》[批准号：59776033]为资助，针对我国兆瓦级风力发电机组风轮叶片存在问题，进行了兆瓦级风力发电机组风轮叶片基础实验研究。

This paper presents a wind vane sensors without the use of cases, combining with gyroscopes and hill-climbing algorithm to control the yaw institutions, can accurately capture the wind direction signal, rapid-conditioning the cabin of the deflection angle, so that wind generators wind wheel normal direction of the wind direction and change is always consistent for maximum capture of wind energy control strategies.

针对风力发电机组的风向变化绝对值小于15°的风能捕获率问题，提出一种在不使用风向标传感器的情况下，采用陀螺仪和爬山算法相结合的方法来控制偏航机构，能够准确的采集到风向信号，快速调节机舱的偏转角度，使风力发电机风轮法线方向与变化的风向始终保持一致，实现最大捕获风能的控制策略。

Chinese traditional virtue is humility and wariness,the compliment and praise to the others should be declination
