The paper studies acting force and movement law of the carrying electricity dust, and sets up hydromechanics equation of the air dust.

Developed a high-powder,efficient and practical air powder vacuum cleaner after studing its working principle in order to suck up air powder,the vacuum cleaner is vevy practical.

Effect of space dust impact on high temperature thermal pipes for spacecraft;

On the research progress in damage effects of space dust environment on external materials in spacecraft;

With the development of space technology, the cumulative hypervelocity impact damage effects of micro-size space debris and micrometeoroid (space dust) are getting more attention.

The installation of fine dust on-line monitoring equipment in the BF gas dust-removing system and the entrance pipes of TRT unit can efficiently control the efficacy of dust bags and realize the on-line detecting of gas dust content in TRT unit entrance pipes,thus ensuring the running conditions of TRT unit and its long-term, high-efficient and safe running.

The initiation of the cracks was caused by stress corrosion resulting from the co-effect of the corrosive gas dust and the axial tensile stress.

Installation of dust on-line monitor device in the dusting system of blast furnace gas and in inlet pipe of TRT set could effectively control cloth-bag dusting effect and realize on-line examination of gas dust content in the inlet pipe of TRT set.

The pneumatic bridge sensor of the measuring system for separating sulfur from flue gas and dust is studied.
