adding ratio of hydrogen的用法和样例：
- Dimethoxymethane possesses higher quantity of oxygen, higher ratio of hydrogen to carbon and lower flash point.
- The key to the surprising discovery is tequila's ratio of hydrogen, oxygen, and carbon, which lies within the "diamond growth region.
- It can avoid the influence of crystal water and adsorbed water in catalyst in the process of determining the content of hydrogen of coke. So the method can improve the precision of determining the ratio of hydrogen to carbon of coke on catalyst.
这种测定方法避免了在测氢过程中催化剂结晶水和吸附水对测定结果的影响 ,大大提高了催化剂上焦碳H C的测定精度
- Water is composed of hydrogen and oxygen.
- The photochemical Micro-reaction of hydrogen and chorine and the condition, such as the light intensity, the purity of the gas the volume ratio of the mixed gas, the time interval is discussed.
