用质量数之比代替质量之比并没有错

It's Not Wrong that Nuclear Mass Number Ratio Replaces Nuclear Mass Ratio

指出《一种错误不能再流传了》一文中用质量数之比代替质量之比并没有错,这样的代替所带来的误差是很微小的,分析计算并举例说明了它的可行性.

It is pointed out that there is no wrong about the mass number ratio of atomic nuclear being used instead of the nuclear mass ratio in the article 《Stopp making this mistake》,since the error is infinitely small in doing so.And the feasibility of this substitution is analysed,calculated and illustrated by examples.
