将这一方法应用于铂电极上铁氰化钾还原反应体系中的研究结果表明，超声功率与电极反应电流幅值信号呈正比的关系，反映了超声能量对电极表面传质过程的影响程度的对应关系；电流信号幅值与超声作用距离的反比例关系则反映了超声振动能量随其辐射距离增大而衰减的规律性。

The results from the study on the decoloring conditions of strain 3# showed that the pH range for decoloring reaction was 5～11 with 6 ～7 being the optimum, the temperature range was 10～30℃ with 30℃ being efficiency optimal. The decoloring efficiency was higher under the presence of oxygen than that lack of oxygen. Strain 3# could more strongly decolor malachite green under optimum conditions. The decoloring rate was above 50%, 70% and 90% in 4, 12 and 24 h treatment, respectively.

对3#菌株的脱色反应条件进行初步研究表明，3#细菌的脱色反应的pH为5～11，最佳范围pH 6～7；温度10～30℃，最佳温度30℃；有氧气情况下的脱色效果较缺氧情况下好；在最佳条件下该菌对孔雀绿染料的脱色作用较强，处理4、12、24 h后，色度去除率分别达到50%以上、70%以上和90%以上。

In Chapter 2 of this thesis, the kinetic equation of substrate reaction in presence of denaturant has been derived. A re-examination of the effect of high concentrations of guanidine hydrochloride on the inactivation of papain, taking into consideration the effect of high concentrations of guanidine hydrochloride on the Michaelis constant, showed that, for papain, the substrate gives no protection on its inactivation.

我们在第二章中推导了变性剂存在下的底物反应动力学方程，并在考虑了高浓度盐酸胍对酶催化反应米氏常数的影响的前提下，根据推导的动力学方程重新分析了盐酸胍存在下木瓜蛋白酶的失活动力学，结果表明底物对木瓜蛋白酶的失活没有保护作用。

因为介白素十号(IL-10)有压抑细胞性免疫反应（例如杀手细胞及吞噬细胞），却提升体液性免疫反应的作用，而EB病毒晚期基因BCRF 1与介白素十号有相似的基因序列（又称vIL-10），也可能具有相似的功能。

EDD and NEDD of external iliac artery in vivo (measured with high-resolution ultrasound), serum lipids, NO, NOS, plasma ET, ADMA, symmetric dimethylarginine and L-arginine, the area of AS plaque in thoracic aorta (dyeing with Sudan Ⅳ), the degree of AS lesion in abdominal aorta and external iliac arteries, NOS activity on the wall of the abdominal aorta, the expression of iNOS mRNA and eNOS mRNA on the wall of the abdominal aorta and the contractive and dilatant functions of abdominal aorta and external iliac arteries in vitro; B. the activities of dimethylarginine dimethylaminohydrolase in kidney (including the establishment of the determining method). 3. In the third part of the study, normal aorta strips were used. The following were surveyed: their response to using ADMA alone, influence of treating with ADMA, intervention of polydatin, influence of using ADMA and PD together on Emax and Kd that were contracted by PE.

The results of further experiments show that most of the metallic oxides give a catalytic effect on NO/CO reaction, while pre-reduced Ni2O3 sample shows remarkable catalytic activity to the direct decomposition of NO.

大部分金属氧化物以对NO/CO反应的催化作用为主，而Ni2O3的预还原试样对NO的直接分解反应表现了极强的催化活性。

DTA and experiments of thermal explosion show that the Ti-B_4C reaction can be happened at a relative lower temperature by the ejective heat from Al-Ti reaction because of Al working as a catalyst in Al-Ti-B_4C system.

DTA和热爆试验表明，由于Al起催化剂作用，Al-Ti间反应放出的热量，使得Ti-B_4C间的反应在一个相对较低的温度条件下发生。
