Exploration of mechanics in wood collapse;

Study on Reduction of Collapse of Eucalyptus Wood in Drying;

Methods From July 2001 to September 2003, twenty-two patients (average age 28, 19～36 years old; 18 males and 4 females; 15 right knees and 7 left; 9 from sports injury, 7 from traffic accident and 6 by sprain injury) with symptomatic laxity and confirmed elongation with rupture of structure were operated with bipolar radio frequency thermal shrinkage under arthroscopy.

Taking the winding heads CW6 by Barmag Germany,analysis is done to the factors causing the craping deforming of bobbins FDY in process of varieties of long fiber production.

Objective: To investigate the effects on blastocysts survival and subsequent in vitro and in vivo viability of “artificial shrinkage” before vitrification of mouse expanded blastocysts using cryoloops technique.

Objective To observe the effect of Nd:YAG Laser on the treatment of capsule contraction syndromeafter cataract phacoemulsification.

The results showed that: collapse depth, volume contractive rate and collapse factor of the heartwood gradually decrease in the stem height direction, collapse factor is bigger in the middle of the total-tree height.
