A set of experimental data which describes a curve on semilogarithmic paper may reflect the operation of a continuum of exponential processes, particularly in biological systems where variability is expected. The "backward projection" technique for graphic separation of exponential processes is most misleading when applied to systems in which the processes are distributed so that the standard deviation of halftimes is large compared to the mean halftime.
一套描述半对数纸上曲线的实验数据可能反映了一系列指数过程的运作，特别是在预期存在变异性的生物系统中。当应用于过程分布的系统时，“反向投影”技术用于图形分离指数过程是最具误导性的，因为半衰期的标准偏差与平均半衰期相比很大。
