1.A tuning fork socket tester is also needed to do final test without damaging the balls.
2.Since solder balls do oxidize quickly and builds an oxide coat that reduces the soldering characteristic of the ball, the chips should be vacuum sealed shortly after the reball process.
3.Methods Absorbable balloon was produced the diameter of which was (1.9) cm,using absorbable high polymer materials PDLLA-CL made from the homoconjugate DL-lactic acid and ε-caprolactone with ratio of 70:30.The in vitro degradation and animal tests were done for the sake of observing the healing results of the tibial upper end bone returned-graft and degradation of the ballon.
4.The results showed that young leaves and shoot-tips are the best explants for PLB induction.
5.In stem tip culture of Phalaenpsis aphrodite in N_6 medium at 25 ℃ and 2 000 lx,the protocorm of it can be induced after two months.
6.To improve the embryogenic capability of the calli induced from micro-cross section explants cut from corms of in vitro plantlets of banana (Musa AAA Cavendish subgroup cv. Brazil), the effects of nitrogen source and x[NH~+_4]/[NO~-_3] ratio on the callus induction were investigated.
7.The effects of different basic media(1/3 MS,1/2 MS,MS,VW), different organic compounds (coconut milk, potato, banana and apple ) and hormone on the propagation of Phalaenosis PLB (Protocorm like-body) were studied by adopting phalaenopsis PLB for explant culture.
8.After grafting, ready- made acetabular prostheses were implanted in 9 hips, while special prostheses were used in 24 hips, chiefly computer- aided custom- made acetabular prostheses, including winged prostheses, 2- layer metal mesh, acetabular reinforcing rings (ARR), bi- spherical prostheses, crested prostheses and saddle type prostheses.
9.The results showed culture medium of MS+ 6-BA(0.8～1.2)mg/L+NAA 0.1mg/L+Suger 30g/L+Agar 7g/L was suited for the regeneration of Begonia tuberhybrida leaf for the flower industry or reproduction process.
10.Based on the above results,the transformation procedures were as follows: used astransformation recipients ,the cotyledon petioles of AB-Naihan line were treated 3 dayson pretreat medium supplemented with 2,4-D 0.1mg/i and NAA 0.1mg/I ,and cocultured1-2 days with agrobacterium ,then transferred to MS induction medium containing 6-BASmgll and NAA 0.lmg/1;
