Studies on the enantioselective recognition of carbamate-type molecular clefts derived from lithocholic acid;

This paper analyses elongation transformation of warp and off loom shrinkage are affected by the shape of shed of shuttle loom and gripper loo,provide reference for looms of different kinds to design and develop new products.

The dynamic problems of shed warp in the process of weaving ,emphatically the transverse micro vibration of shed warp,the problems of its parameter resonance and transverse resonance were researched in this paper.

Effect on the forming of weft direction defects in weaving stretching weft yarn caused by weft yarn tension control,yarn releasing timing control,heald leveling,shed control,false selvage and leno fastening taking-up motions are analyzed with some reasonable and effective solutions put forward,which can reduce and avoid mispick,kinky weft and so on,and improve elastic denim quality.

Design of Weaving Mechanism for Lead Web on the Shuttle Loom;

The essay analyzes shuttle cracks produced in the middle of the reinforced concrete beam, and deals with a few aspects of common shapelessness, it also discusses the main reason why the shuttle cracks appear and offers what should be paid attention to in designing and carrying, and some general managing methods after the cracks come.
