1) hydrogen to proton mass ratio
氢 质子质量比
2) carbon-hydrogen ratio
碳氢质量比
1.
For it is difficult to get the carbon-hydrogen ratio of gasoline during themeasuring of petrol fuel consumption with carbon balance method, according to therelationship between carbon-hydrogen ratio and gasoline density, a simple mathematicalmodel is derived as a new method for the measuring of gasoline carbon-hydrogen ratio inpractice.
鉴于用碳平衡法测量汽油机耗油量时汽油碳氢质量比难以测定，根据汽油碳氢质量比与汽油密度的对应关系，导出了汽油碳氢质量比与密度关系的简单数学模型，为汽油碳氢质量比的测定提供了一种新的方法。

目的运用多体素二维氢质子磁共振波谱法(1H-MRS)分析皮层下动脉硬化性脑病(BD)梗死灶和缺血灶代谢产物的代谢特征和变化规律。
4) hydrogen bond proton
氢键质子
5) proton
[英]['prəʊtɔn] [美]['protɑn]
质子，氢核
补充资料：碳氢比
碳氢比就是c/h的比例.
一般情况下,是以c的质量比上h的质量.
在化工方面有着重要意义的参数.可以表征这个化合物属于哪一种族化合物的重要参比
