由双指数函数描述的反应对于许多生物过程是典型的。这些反应的动力学描述的超越无理方程互连的试剂浓度，时间和速率常数。同时，它们在半对数坐标系中的图示可以分解为两条相交成一定角度的直线。提出了描述这些反应的方程的渐近数值解的新的简单方法。这些方法允许使用初始物质浓度的动力学数据来确定速率常数，所述初始物质浓度根据双组分模型、顺序模型或竞争模型转化为最终产物。(C)2000 Elsevier Science B.V.保留所有权利。
Reactions that are described by biexponential functions are typical for many biological processes. The kinetics of these reactions is described by transcendental irrational equations interconnecting the reagent concentrations, time and rate constants. Meantime, their graphical representation in the semi-logarithmic coordinates can be decomposed into two straight lines that intercept at some angle. New simple methods for asymptotic numerical solution of the equations describing these reactions are suggested. These methods permit determining the rate constants using the kinetic data of initial substance concentration, which transform into final product according to a two-component model, a sequential model or a competitive model.
