An equation, describing @C01434@ kinetics, of the form: \[1 - \varphi _{c} = \text{e}^{K\ t^{n}}\] where \(\varphi _{c}\) is the crystalline @V06643@ developed at time \(t\) and constant temperature, \(K\) and \(n\) are suitable parameters. \(K\) is temperature dependent. According to the original theory, \(n\) should be an integer from 1 to 4, the value of which should depend only on the type of the statistical model; however, it has become customary to regard it as an adjustable parameter that may be non-integral.
