In this paper, the FIR low-pass digital filtering method is first introduced for reducing the effects of noise signals in the experiment of velocity measurement of high-temperature flue gas flowing in pipe. The experimental results indicated that, only one peak presents in the cross-correlation graph, which is in good agreement with theoretical analysis result. Secondly, the temperature and pressure pulse signals of the high-temperature flue gas, obtained by thermocouple and pressure sensor, are introduced to explain the applicability of sensor characteristics.

A new recovery technology of solid waste was made which is from furfuryl alcohol production by furfural hydrogenization. When the solid waste is placed in a vacuum drying box, and is under lower negative pressure and at 130℃, the organic materials in solid waste can be distilled and then returned to the refining workshop to produce qualified furfuraldehyde and furfuryl alcohol. The remainder is mixed with soda ash and roasted in a reverberating furnace. The sodium chromate can be obtained by leaching. Rough cupric oxide is dissolved in nitric acid and cupric nitrate is obtained. A new catalyst was prepared by the above sodium chromate and cupric nitrate and used in furfuryl alcohol production.

The experimental study on higher-temperature fusing properties of coal ash and materials shows: it is high ash content and low volatile matter content rather than the fusion point value that are the main factors which influence primary the temperature of liquid phase of cement raw meal.

本文通过灰熔点的实验方法，进行的煤灰及物料高温熔融性研究表明，煤灰灰熔点的高低并不是影响水泥生料液相初析温度的最主要原因，而煤中的高灰分及低挥发分却是关键因素。

These salamanders originally lived in cold northern areas. About 0.1 million years ago in a glacial epoch , they moved to Taiwan. They immigrated to the higher mountains above an altitude of 2,000 meters, because the temperatures in the lower areas were getting hotter and hotter.

原本山椒鱼居住在寒冷的北方，但大约十万年前的冰河时期，他们迁徙至台湾，由於较低的区域温度越来越热，他们移往海拔2000公尺以上的高山。

The accumulation of snow and ice during a glacial period increases the surface albedo, reflecting more of the Sun's energy into space and maintaining a lower atmospheric temperature.
