线性反应系统和一些非线性反应系统的一个重要结构特点就是存在直线反应路线.本文指出了M~α(?)型线性反应系统中唯一可观测的直线反应路线的二维表达式的特点,并由此出发推导了该直线反应路线的初组成—射线向量的数学表达式和它与热力学平衡组成向量的关系;同时也指出了建立可逆线性反应系统和某些非线性反应系统的直线反应路线的初组成和速度常数之间的数学关系的可能性.本文利用射线向量的数学表达式作为反应系统中速度常数的线性等式约束,用可变误差多面体法求出了八碳芳烃临氢异构反应系统的相对速度常数,并在工业条件下的选择性动力学研究中得到验证.实践证明这种作法减少了曲线拟合时所估参数的不定性,从而为复杂反应系统速度常数的估值提供了一种有效的手段.
An important structural feature of the linear reaction system and some nonlinear reaction systems is the existence of a linear reaction path. In this paper, the characteristic of the two-dimensional expression of the only observable linear reaction path in the M-α linear reaction system is pointed out. Based on this, the mathematical expressions of the initial composition-ray vector of the linear reaction route and its relationship with the compositional vector of the thermodynamic equilibrium are deduced. At the same time, it is also pointed out that the linear reaction route between the system of reversible linear reaction and some nonlinear reaction systems The initial composition and the speed of the mathematical relationship between the possibility of the use of ray vector mathematical expression as a linear system of velocity constants constraints, using variable-error polyhedron method to determine the ochrocarban hydroisomerization The relative velocity constants of reaction systems are validated in selective kinetic studies under industrial conditions.It has been proved that this method reduces the uncertainty of the estimated parameters during curve fitting and thus provides an estimate of the velocity constants of complex reaction systems Provide an effective means.
