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.

The theoretic solutions of position response characteristic of two-dimensional tetra-lateral PSD illuminated by the static and moving light source were solved.

Use static elements or relative static elements in the changing graph to get the main moving point and its relations with other known conditions to correctly calculate the orbit equation.

Using Lorentz alterrnate, this paper bears out force of motion electric charge acting on static charge.
