A new airborne AgI flare seeding generator was described in the aspects of the development process,structure,alteration,and application,which was developed in the project of the national key research project Demonstration of Precipitation Enhancement Techniques.

Application of chlorine dioxide gas and exploitation of the generator;

Technology of numerical control super high pressure machine tool in abrasive water jet cutting generator system;

Design improvement of open low pressure acetylene generator;

Based on this issue, it describes the details of the sealing dynamic system including Hydrogen Generator and Titanium Absorption Pump.

The longitudinal vortex generator is a new technique of enhanced heat transfer,this paper presents the effects of the longitudinal vortex in horizontal rectangled duct on the heat transfer coefficient and pressure drop.

Delta winglet vortex generators (DWVGs) can generate longitudinal vortexes in a channel.

This paper studies the heat transfer enhancement when fixing triangle vortex generators on the horizontal heating surface, while keeping low wall temperature (less than 120 ℃), making air in the condition of forced convection and Re number be in the range of 800 to 7 000.
