Secondly, the silver based catalysts modified by phosphorus, zirconium, zinc, potassium and so on using molecular sieve as carrier, which were produced by ion-exchange method, had also good catalytic performance for 1,2-propane glycol oxidation to methylglyoxal.

The same methods were used to study toluene dinitration, and the results indicated that the thermal runaway risks of these reactions were low too; prolonging dosing duration was helpful to the conversion of all nitrotoluene; decreasing the molar ratio of nitric acid to mononitrotoluene would make an insufficient conversion; among the given temperatures, rising reaction temperature couldn\'t markedly change the yield coefficient, but lead more heat generation and higher thermal runaway risk.

采用同样的方法对二段硝化反应进行研究，结果表明：二段硝化反应的热失控危险性也较低；延长加料时间，有利于反应完全；而随着硝酸与一硝基甲苯摩尔比的减小，硝化难以进行完全；在选定温度范围内升高温度，产物得率无显著变化，反而易导致放热加剧，增加体系的热失控危险。

Finally, in discussing different industry's classifications, it observes the electrical industry is not influenced by the selected parameters of this research while setting conversion premium, but the conversion premium of the nonelectrical industry is influenced by debt-convertible dummy, debt ratio and issue size.

There had been a moment during the breakfast meeting, though, after the backslapping and the small talk and when all of us were seated, with Vice President Cheney eating his eggs Benedict impassively and Karl Rove at the far end of the table discreetly checking his BlackBerry, that I witnessed a different side of the man.
