On the base of finding out the difference of tectonic soft coal and hard coal on apparent resistivity, it expounds the gas-geology methods: to explain geology tectonics as well as tectonic soft coal, drawing a circle of around unusual area of tectonic soft coal according to the tunnel perspective data of face, and then to forecast the dangerous area of coal and gas outburst of face.

Reaction to radio tunnel perspective and general patterns of small geological structures such as washouts,caving columns faults,igneous rocks and rock like door curtain in longwall faces are introduced in this paper.

Application of small scale turbomachine in chlorine transportation;

In this paper a heat-flow coupling mathematic modeling about cascade flowing field and blade temperature field in turbomachinery is built.

It has been experimentally investigated the effects of drop-shaped pin fins on heat transfer and pressure loss for the blade trailing of turbomachinery.

The recent research and development of the sealing technology in modern turbomachinery is reviewed.

Summary of innovation of conveying technology of chlorine gas turbine;

The feasibility of developing the torpedo thermal power system turbine trial model to attack the large surface warship is analyzed.

This paper describes the industrial tests on the main gas parameters having impact on TRT power, the flow rate, pressure, temperature and dust content of the gas into turbine.

This paper gives a method of combining experiment with theoretical calculus, which can be used to obtain the precious vibration mode functions of disk bladed of turbine machinery.
