5.The Whole Destructive Experiment of Prototype Standard Unit--Building of Framed Light--Weight Panel——the Introduction of a Timed Loading Method
6.This paper introduces application of back pressure loading unit in the actuating cylinder endurance test of K - 8 and JL - 8 aircraft The back pressure loading unit features simple structure and low test cost and well as it is not influenced by the temperature change, that could give the actuating cylinder a constant loads.
9.By means of mixing Xinjiang Long staple cotton and 20% uplands cotton,in blowing carding unit composed of china made machines without condensers in the whole process and imported single unit and spinning system,which after combing onedoubling and spun yarn with pneumatic loading system,take the process technology measures,such as light constant weight,slow speed,short gauge,strengthening combing combinaion and lightening elastic top rollers etc. All these may efficiently improve the quality of fine high counts yarn,such as CJ7 3 tex etc.
