Americium has lots of species in aquatic solution. It is difficult to measure the distribution of americium species while they can be calculated by many geochemical software.

Am在水溶液中的形态分布复杂，直接测量困难，使用相关软件依据热力学常数推算核素的形态分布简单可行。

It has been shown that penicillin amidase was very susceptible to the change of temperature, extremely apt to deactivate in the buffer; while the thermostability of enzyme could be improved by an average of 2～4 times in the reversed micelles.

结果表明，青霉素酰化酶对温度非常敏感，在水溶液中极易失活，而经反胶团包埋后，其热稳定性有很大程度的提高，热失活明显减少。

At the same temperature, k〓 in the reversed micelles was always less than k＇〓 in the buffer. According to the thermodynamic analysis for inactivation of penicillin amidase in the reversed micelles, the free energy of activation was increased by 2. 71%, while the entropies and enthalpies of activation were decreased, corresponding to 63. 9% and 76. 9% of that in pure buffer respectively.

由热力学分析可知，青霉素酰化酶在AOT/异辛烷反胶团中的热失活过程，与水溶液中相比，活化自由能△G〓增加了2.71％，而活化熵△S〓和活化焓△H〓分别减小为原来的63.9％、76.9％，从而使酶热稳定性平均提高了2～4倍。

The deactivation rates of penicillin amidase in both systems follow the first-order model. The inactivation rate constants increased gradually and α decreased slightly, with the increase of temperature.

随着温度的升高，失活速率常数k〓和k＇〓逐渐增大，α略有所降低；当体系温度相同时，该酶在反胶团中的k〓值比水溶液中的k＇〓小。

It is existed competitiveness inhibition of 6APA, non-competitiveness inhibition of PAA and substrate inhibition of Penicillin on the hydrolysis of benzylpenicillin to 6APA and PAA by an immobilized penicillin amidase. The heat conductive coefficients were determined on the vacuum elevation liquid membrane concentration. The thermodynamics and kinetics of PAA extraction were studied on the organic solvent extraction of the above solution.

研究证明固定化青霉素酰化酶裂解反应是典型的底物、产物抑制酶反应，其反应动力学数据表明，青霉素、苯乙酸以及6APA对反应分别存在底物抑制、非竞争性抑制和竞争性抑制；真空升膜浓缩适应热敏性以及粘度不大的物系，对于6APA水溶液的真空升膜浓缩过程研究得到了浓缩实验的传热系数；浓缩液萃取主要是提取出其中的苯乙酸，本文测定了不同温度以及溶剂条件下的苯乙酸溶解度，并观测了苯乙酸萃取动力学。
