We also strongly suggest that the recently reported chaperone acitivity of periplasmic PDI-ase and PPIase assayed by traditional substrate should be reexamined using periplasmic proteins as substrate due to the significant difference between those two classes of proteins, the possible chaperone fuctions of PDIase and PPIase in vivo should be reappraised.

同时，由于本实验结果显示膜间质蛋白与常用的分子伴侣测活底物蛋白在聚集行为上存在极显著的区别，我们建议对最近报导的膜间质蛋白二硫键异构酶和脯氨酸顺反异构酶分子伴侣活性以膜间质蛋白为底物再进行验证，对其在膜间质是否发挥分子伴侣功能重新慎重考虑。

First, 2 molecules of acetone coordinatedwith aluminum by electrostatic attraction . One atom of hydrogen ofacetone migrated to aluminum because of the pulling of the negativeoxygen of aluminum, and then aldol condensation occured.

该催化反应可以认为是氧化铝分子与两分子丙酮分子发生静电络合作用，然后借助氧原子的负电荷导致脱氢并实现缩合。

Through taken the measurements of pH, TOC, UV-Vis spectra and high-performance liquid chromatograph in the degrading process of solution ,it was found that the COD of dye solution increased, pH continuing declined and TOC reduced gradually. The UV-Vis spectra and high-performance shown that though dye molecules had been destroyed, Strong Chromophore Azo Double Bond of dye was certainly under attack, the big conjugated system was vandalized and dye molecules were decolorized degradation, but they were not completely changed into carbon dioxide and other inorganic matter by mineralization, it appeared accumulation of aromatic ring and double benzene nucleus, so it is thus evident that complete destruction of aromatic ring is more difficult than the double benzene.

通过测定直接大红染料脱色过程中的溶液pH、TOC、紫外可见光谱图和高效液相色谱图可知，在脱色处理时间(6h)范围内，染料溶液的COD值增大， pH值持续下降，TOC值逐渐降低，结合紫外可见光谱图和高效液相色谱图，说明染料分子虽然已经遭到破坏，染料分子内强生色基团偶氮双键确实遭到攻击，大的共轭体系被破坏，染料分子被脱色，却没有完全被彻底矿化成二氧化碳等无机物，出现了芳环和萘环结构的累积现象，可见完全破坏芳环比破坏偶氮双键发色团更困难。
