In 1838 a differential equation was developed by Verhulst to explain what is currently termed the S-shaped curve. Reviewed here are his application of the equation to population data and significant later applications by various workers to problems in physics, chemistry, and biology. The usefulness, versatility, and convenience of this integrated equation are illustrated by examples from our own work, including superimposition of data by use of reduced variables.
1838年，韦尔哈斯特提出了一个微分方程来解释当前所谓的S形曲线。本文回顾了他将该方程应用于人口数据的情况，以及后来不同工作者将其应用于物理、化学和生物学问题的重要情况。通过我们自己工作中的例子，包括使用简化变量叠加数据，说明了这个综合方程的实用性、多功能性和便利性。
