的存在和行为的拐点时间(在速率-时间依赖性的转折点)已被调查的自催化反应中的组分的初始浓度的函数。对于一组速率方程,它示出的拐点时间是一个严格的自催化剂的初始浓度的递减函数。当自催化剂的初始浓度固定时,拐点时间可以达到最大值和最小值,或者可以在任何地方随着底物的初始浓度增加而增加。即使当速率方程是对称的时,两个分量的影响的差异仍然存在。实例和一些实际的后果进行了讨论。
The existence and the behaviour of the inflection time (the turning-point in the rate–time dependence) has been investigated as a function of the initial concentrations of the components in autocatalytic reactions. For a group of rate equations it is shown that the inflection time is a strictly decreasing function of the initial concentration of the autocatalyst. When the initial concentration of the autocatalyst is fixed, the inflection time may attain maxima and minima or may be everywhere increasing with increasing initial concentration of the subtrate. The difference in the influence of the two components remains even when the rate equation is symmetric. Examples and some practical consequences are discussed.
