摘 要:
以黑洞为例，在不考虑满足幺正性的情况下得到了在背景辐射中Schwarzsehild黑洞的质量随时间变化的微分方程，并对该方程进行了必要的研究和讨论，作为对《新概念物理教程·力学》和《新概念物理教程·热学》中提到的负热容量系统的不稳定性的另一个注释．文章最后用Runge-Kutta法数值模拟了Schwarzschild黑洞的质量演化过程，使广大学生能够更直观地理解这一过程．[著者文摘]

Abstract:
A differential equation of the mass of system with negative heat capacity in background radiation, for example Schwarzschild black hole,is obtained ignoring an underlying unitary theory. A necessary study and discussion on the equation, mentioned in《Mechanics of new concept physics》, and《Heat of new concept physics》 are made. At the end a numerical simulation of the mass evolvement is carried out using Runge-Kutta method. It helps students understand the system with negative heat capacity more easily.[著者文摘]
Key words:
