The batch seeded isothermal desupersaturation experiments of SPM in aqueous solution were carried out and the overall crystal growth kinetics parameters were determined by the nonlinear optimization techniques. Assuming that the volume diffusion rate at growth is equal to the mass transfer rate at dissolution under the same conditions, the two-step crystal growth rate parameters can be determined. At the fow supersaturation, the surface integration rate is proportional to relative surface supersaturation.

通过测量螺旋霉素均相成核动力学，获得了表面能的值，估算出表面熵因子的值在1.41～1.56之间，从而可以推断出螺旋霉素晶体生长的表面反应速率同表面相对过饱和度成线性关系，这种生长机理同第四章得到的结果是相吻合的；利用估算的表面熵因子的值，把螺旋霉素晶体看作为简单的立方科瑟尔晶体，根据能量最低原理，对螺旋霉素的晶体生长进行了模拟。

In this study, we investigate the heat-induced inhibition of drug-metabolizing enzyme activity in mice fed with freeze-dried, heated freeze-dried or half amount autolyzed freeze-dried Brussels sprouts powder. 0.5% ethoxyquin diet was fed to another group of mice as a positive control. The study mice, four per group, were fed a diet consisting of 20% Brussels sprouts for 7 days. Each group had its own pair-fed group. We found significantly greater inductions of glutathione S- transferase, quinine reductase, and phase Ⅱ drug-metabolizing enzyme activities in groups fed within freeze-dried and heated freeze-dried Brussels sprouts than their pair-fed groups. These findings indicate that intestinal microflora still can hydrolyze glucosinolates without plant myrosinase activity, though the alteration of cytochrome- P-450 1A (CYP1A, a phase Ⅰ drug-metabolizing enzyme) induction was only 1.4-fold.

本实验欲进一步探討加热处理之抱子甘蓝对phase Ⅰ与phase Ⅱ解毒酵素活性之影响差异，实验分三组，抱子甘蓝(1)冷冻乾燥组（glucosinolate未裂解）(2)加热冷冻乾燥组(3)半量之裂解冷冻乾燥组（glucosinolate已裂解），(4)and 0.5% ethoxyquin diet was used as a positive control以2%重量混合成饲料，餵以小白鼠（4只／组）7天，结果发现，在第(2)组小白鼠GST phase Ⅱ酵素）活性显著上升，显示在植物裂解酵素不存在之状况下，肠胃道之微生物仍可促进裂解反应，但由CYP1A活性增加不显著（仅1.4倍）看来，根据定义：单独phase Ⅱ酵素活性增加，为monofunctional induction/inducer，可加速致癌物之代谢。

This study demonstrates optically and spatially band-tunable color cone lasers based on DDCLC cells with a photoisomerizable chiral dopant. The band-tunability is attributable to the recovery of the helix of the CLC resulted from the trans-cis isomerization induced decrease of the helical twisting power of the chiral dopant.The more the chiral cis-isomers are produced, the larger the tuned lasing band is.

本文主要藉由在胆固醇液晶射中加入可光致同素构化亲手性材，使胆固醇液晶所输出的彩色锥角射波段可光调控及空间调控，其射输出波段可调控的机制是由於当同素构化反应产生后，光致同素构化亲手性材的HTP值低并造成胆固醇液晶距改变，藉此间接调控输出的射波长，同素构化的程愈高，胆固醇液晶所输出的彩色锥角射波段可调控范围也愈大。
