拉普拉斯（Laplace)定律 P=2T/r 。 P 代表肺泡回缩力，T代表表面张力，r代表肺泡半径。肺回缩力与表面张力成正比，与肺泡的半径成反比。
考虑到掺质和尺寸效应，得到了金刚石烧结体系中拉普拉斯第二定律的一个普适性方程和相应的界面结合特征方程。
In consideration of the doping and dimension effects a universal equation of Laplace second law and the interface binding characteristic equation in the sintering system of diamond were obtained.
电场的数学基础包括：库仑定律的积分形式、高斯定理的积分形式，拉普拉斯公式和泊松公式，散度定理。
Topics for the electric field mathematics include: The integral form of Coulomb's Law, Gauss's Law, the equations of Laplace and Poisson, and the divergence theorem.
这种情形下的宿命论是显而易见的，但拉普拉斯进一步假定存在着某些定律，它们类似地制约其他每一件东西，包括人类的行为。
Determinism seems fairly obvious in this case, but Laplace went further to assume that there were similar laws governing everything else, including human behavior.
