本文导出了等温球形气体在自身引力和外压作用下平衡时的波义耳定律的修正形式，并给出了典型的p-V曲线。任何这样的气体质量如果被充分压缩，都是重力不稳定的。它还表明，一个足够大的等温气体球是不稳定的，这是比较的条件与金斯的引力不稳定性公式。
A modified form of Boyle's Law is derived for a spherical mass of gas at Uniform temperature in equilibrium under its own gravitation and an external pressure, and a typical p–V curve is shown. Any such mass of gas is gravitationally unstable if sufficiently compressed. It is shown also that a sufficiently large isothermal gas sphere is unstable, and the condition for this is compared with Jeans' formula for gravitational instability.
