失重

The order of total weight loss rate of biomass under the same condition is as follows:fir sawdust＞corn stalk＞pine sawdust＞erythrina sawdust＞bean stalk＞rice husk＞peanut shell.

相同条件下7种生物质总失重率大小顺序为：杉木屑＞玉米秸秆＞松木屑＞刺桐木屑＞豆秆＞稻壳＞花生壳。

DSC analysis found that the behavior of PSPI-TM film containing TiO〓of 12% was greatly different from that of the corresponding ester-typePSPI film. An intense exothermal change was found on the DSC curve. TGAanalysis indicated that the curve for weight loss of the PSPI-TM film wouldnot reach a platform until 400℃.

DSC热分析表明含TM基于转化后PI的重量折算为12 ％(w／w的Ti〓的PSPI光刻胶膜的热转变行为不同于相应的酯型PSPI光刻胶膜，在300℃附近有一个很强的放热过程；TGA分析表明这种含TM的光刻胶膜直到400℃以上才达到&失重平台&。

The results showed the change of residual flexural strength was controlled by oxidation of carbon phase.

结果表明，残余抗弯强度的变化受C相的氧化控制，残余抗弯强度与失重率之间的变化规律符合指数关系。

Changes of dielectric property of gastrocnemius induced by simulated weightlessness can be observed effectively by frequency domain impedance technique.

利用频域阻抗技术可以有效地观察到模拟失重导致的腓肠肌细胞介电特性发生的改变。

Part I: Characterization of the stability and biocompatibility of PLGA conduits.1 Artificial nerve conduits were successfully fabricated using two different copolymer ratios of PLGA(85:15 and 50:50)(lactide:glycolide).2 Degradation of PLGA(85:15) and PLGA(50:50) conduits were examined in vitro for 12 weeks in phosphate buffered saline at 37℃, pH 7.4 and in vivo for up to 8 weeks following implantation into the rat dorsal muscle.

结果显示：①体内外降解条件下，PLGA(50：50)管吸水率、失重率及生物降解率显著高于PLGA(85：15)管；②两种材料样品体内生物降解率显著高于体外降解率；③扫描电镜观察显示，随降解时间延长，材料样品表现为特征性的虫蚀样破坏并进行性加重，以PLGA（50：50）管尤为明显。
