This thesis is mainly concerned with mechanism of air preheater after-burning and air preheater hot spots detection technique based on image of temperature field.

本文主要研究了电站锅炉空气预热器发生二次燃烧的机理以及基于温度场分布图的空预器热点检测系统。

This essay analyzes the method and procedure of ice-making recorded in Huai Nan Wan Bi Shu, and creatively proposes that the principle of "ice-making in summer" is refrigeration through the quick evaporation of water to absorb heat under low pressure, and that ice is made on the fine silk at the mouth of an urn, but not inside the urn at its bottom as it was conventionally thought. The essay points out three necessary conditions which should be fulfilled in order to realize "making ice in summer": low relative humidity (less than 26%), large volume of the urn (about 100 L) and proper air temperature (about 20℃).

分析《淮南万毕术》所载制冰方法和过程，提出低压下水快速蒸发吸热制冷是"夏造冰"的制冰原理；结冰的部位不是传统观点所认为的瓮底，而是在瓮口的嫌上；指出要实现"夏造冰"，需满足三个条件：相对湿度低（低于26%）、瓮的容积大（100升左右）、空气的温度适当（20℃左右）。

According to characteristic of ultrasonic spreading in the air, the data disposal method of ultrasonic range finder, the hardware realization of the equipment and the method of temperature compensation used in order to improve the measuring precision had been discussed.

详细研究了高温氧化行为的粉加工Ni3Al （燃烧合成的，被动压，和反应挤出）在空气中在两个不同的温度（ 1000年和1200年 C ）作为400 H获得开展。

Study results show that the thermal transmission characteristic of the radiation recuperator is variable during the heat treating process,and the average preheating temperature of air is not capable of achieving the rated design value of the recuperator.

结果表明，燃气辐射换热器的传热特性在整个热处理过程中是不断变化的，空气平均预热温度并不能达到换热器的额定设计值，故在周期式热处理炉上使用辐射换热器并不完全合适。

To lessen the strain on heating and air-conditioning equipment, builders of skyscrapers have begun to use double-glazed panels of glass, and reflective glasses coated with silver or gold mirror films that reduce glare as well as heat gain. However, mirror-walled skyscrapers raise the temperature of the surrounding air and affect neighboring buildings.

为了减轻取暖设备或空调设备的压力，摩天大楼的建造者们已经开始使用双面上釉的玻璃镶板和涂上了金色或银色反光薄膜的反光玻璃，来减少强光照射和热量的增加；但是，镜面的摩天大楼会提高周围空气的温度并会对附近的建筑物产生影响。
