During long - term drug therapy , the extent of absorption is the more important measurement because average concentration depends on it ; the degree of fluctuation is related to the absorption rate constant 在长期药物治疗期间，吸收的分量测量指标更重要，因为平均浓度就是根据它来计算的，而浓度的波动程度则与吸收速率常数有关。

It is indicated by quantum chemistry calculation that dissociation energy of ti , c and si is 108kj / mol , 499 . 7 kj / mol and 626 . 1 kj / mol , respectively , coincided well with the experimental ones found in literatures 量子化学计算表明其离解能分别为108kj mol 、 499 . 7kj mol和626 . 1kj mol ，与文献报道的试验值吻合。离解能数据及速率常数的计算均证明ti的离解较为容易。
The intrinsic chemical reaction rate constant was insensitive to the precursor and the calcinations history of cao , but the product layer diffusivity was affected by these two factors in the initial stage and decreased to a constant value with increasing conversion of cao 化学反应速率常数不受氧化钙的先驱物与其锻烧程序所影响，但产物层扩散系数在初始阶段则受到上述两因素的影响，并随著氧化钙的转化而减少至一定值。
In the last , we find that the reaction rate c onstant and the cross - section have the similar rule for the quantum numbers j and m . finally , at present our calculated results are one of the most accurate results of the reaction h + cd4 hd + cd3 最后比较各个量子态的速率常数，我们也看出随量子数j的增加，速率常数升高，随量子数m的增加速率常数降低，这些曲线在我们的图中都呈现相似的下降趋势，这和散射截面的规律是吻合的。
The photocatalytic dynamics of two important and representative organic substances - methylene blue and methylene orange . those two organic substances could be directly degraded without tio _ ( 2 ) by uv lamp . the type of reaction belonged to typical first - degree reaction 由实验可知，在无光催化剂时，紫外线可直接降解有机物，其反应机理属于典型的一级反应，降解甲基橙和甲基蓝的反应速率常数分别为0 . 0013min ~ ( - 1 )和0 . 004min ~ ( - 1 ) 。

The crystallization property were investigated by dsc . it was shown that the joining of ommt has a little effect on melting point of pp , the crystallization temperature of pp was improved obviously and the degree of crystallinity was increased ; through studying on kinetics of isothermal crystallization , the constant ( k ) of crystallization speed and crystallization speed ( g1 / 2 ) were lowered with rising of crystallization temperature ; half period of crystallizations and ( tp ) were delay with rising of crystallization temperature Dsc研究结晶行为表明：有机蒙脱土的加入对pp熔点的影响不大，使pp的结晶温度明显提高，结晶度增大；通过等温结晶动力学的研究，结晶速率常数k和结晶速率g _ ( 1 2 )均随结晶温度的升高而降低；半结晶期t _ ( 1 2 )和t _ p都随结晶温度的升高而延长。
The results showed that the mic was controlled by three factors ( the content of ag ~ , the proportion of surface and the status of crystal ) at normal temperature with which matched m = amoexp ( - kc ~ 3 . it also showed that when the ag ~ was on the powder ' s surface , the anti - bacterial capacity of power was controlled by the action of cell death . 4 ) the toxicological test the toxicological properties of the powders , which was prepared in different route , was tested 建立了抗菌粉体的抗菌机制：粉体的最小抑菌浓度由银离子含量、粉体比表面积和二氧化钛的结晶状况三种因素控制，它们遵循m am _ 0exp ( - kc _ ( ag ) )关系；当粉体表面的银离子过量时，粉体的抗菌能力受细胞死亡反应控制，为一级反应，粉体的抗菌能力越强，细菌的死亡速率常数越小。
A piezoelectric immunosensor was developed by immobilized transferring antiserum on the surface of quartz crystal to especial answer transferring , it can be get good answer to determined in the range of 3 . 92 ~ 79mg / l ; the adsorption and desorption of consult serum on the quartz crystal monitored with tr - antibody , determined the rate constant of immuno - reaction was 2 . 14xl07 ( mol / l ) ' 1xs ' 1 , the association constant of the immuno - reaction ( k1ss ) was 6 . 75xl07 ( mol / l ) ~ l Oz vomg l范围内的参考血请中的转铁蛋白进行了定量测定，获得很好的响应；利用石英晶体微天平技术在线监测了参考血清在固定了转铁蛋白抗体的石英晶振上的吸附与解吸过程，测得了其抗原抗体免疫反应的速率常数为2 14xl0 ’ （ mol l ） ’ xs “ ‘ ，结合常数为6
