中文摘要：

对于为论证球形液滴附加压强的Young—Laplace公式而设计的一个理想实验，有文献试图借助吉布斯自由能函数进行证明，本文给出符合这一条件的证明方法．

英文摘要：

A known ideal experiment used to prove the Young-Laplace equation of spherical liquid drop is analyzed by using the Gibbs free energy. We point out the mistakes of the reference [ 7 ] and give the correct formulation.
