It has long been known that the chemical atomic weight of hydrogen was greater than one-quarter of that of helium, but so long as fractional weights were general there was no particular need to explain this fact, nor could any definite conclusions be drawn from it.
人们早就知道氢的化学原子量大于氦的四分之一,但只要分数权重是一般的,就没有必要特别解释这个事实,也不能从中得出任何明确的结论。
