详细论证了动力学体系中存在的多种共线性情况,以及在此情况下二维数据阵的秩与独立反应数及组分数的关系 分析了通过增秩这一方式来判断体系组分数的条件 讨论了反应间存在物质交换对数据阵秩的影响.建立起一套通过秩分析判断未知动力学体系中存在的反应组分数、独立反应数以及可能反应机理的方法.将秩分析技术应用到聚苯胺与质子酸反应,初步分析了该体系存在的多种吸光性结构及结构变化.确定了[H+]=0.01-0.1mol·L-1范围内,聚苯胺与质子酸反应存在一个三结构两步互变过程.
The multi-collinearity in dynamical system is discussed in detail, and in this case the relationship between the rank of two-dimensional data array and the number of independent reactions and the number of components is analyzed. The conditions for determining the number of system components by increasing rank are analyzed The effect of material exchange between the reactions on the data array rank was discussed and a set of methods to determine the number of reaction groups, the number of independent reactions and the possible reaction mechanism in the unknown kinetic system were established by using rank analysis.The rank analysis technique was applied to poly Aniline and protonic acid reaction, preliminary analysis of the system of the existence of a variety of light-absorbing structure and structure changes.It is determined that the [H +] = 0.01-0.1mol·L-1 range, polyaniline and protonic acid reaction there is a three structure two Step-by-step process.
