本刊1992年第12期上登载的文章《谈物理量的突变问题》,(以下简称“突变”)中提到:“物理量的突变是指该物理量从某一值变到另一不连续的值历经的时间很短,以致我们认为时间可以忽略不计,”同时总结得到了:“在宏观领域,物体的能量不能发生突变的,决定一个物理量能否发生突变,要根据这一原理去考虑”的原则.对此我以为这一原则是很模糊的,若它是指总能量不发生突变,那么跟能量守恒定律毫无二致,但从 The article “Discussing the Mutation of Physical Quantity” (hereinafter abbreviated as “the mutation”) published in the 1992 issue of the Journal refers to: “A sudden change of a physical quantity means that the physical quantity changes from one value to another discontinuous value. The period of time has been so short that we think time can be neglected. “At the same time, we concluded that: ”In the macroscopic field, the energy of an object cannot be mutated, and it is necessary to consider whether or not a physical quantity can mutate." Principle. I think this principle is very vague. If it means that the total energy does not mutate, then it is the same as the law of conservation of energy, but from
