The result shows that areal density has more effect on insulating ability than needling density and needling density has more effect on peel bond strength,and the processing technology is designed according to it.

The relationship between needling density, the depth of needle penetration and the properties of nonwovens, such as basic physical properties, mechanical properties and filtration properties is analyzed thoughout experiment and theory analyses.

To probe into the anatomic structure,safe needling depth and angle of points Fengmen(B12) and Feishu(B13),steely-needle marked method and layer anatomy method were used in 46 adult corpses.

The research includes four terms as follows:1 Research the records of ancient acupuncture books and Science 01" Acupunciion and Moxibustion, Science of Acupoints of past editions about the needling depth of acupoints on back.

Stab sensitivity should be higher under secured safe condition.

Among those QTLs,12 QTLs which controlling different type needle length were mapped on the same intervals,forming 5 clusters in 4 linkage groups that could control more than one trait,suggesting that there be some pleiotropic effects genes could control the length of different types needle.
