求组织英语语句啊，多谢

　　求组织英语语句啊，多谢。The amount of CH4 is increasing with the cycle number, the main reason is the increase of the pressure-drop. From the perspectives of thermodynamics and kinetics, the increase of pressure-drop, that is, the rise of the reaction pressure can promote reaction (8), which is a volume reducing reaction.

压力损失增大，即反应压力增大能促进反应（8），这个“即”应该怎么组织呢，总感觉这么写有问题啊，多谢。
===有问必答===
可以用 i.e., 代替 that is。

第一句有点问题。要么写成两句话，要么在the main reason is 前面加一个and，或者将其改成 which is caused by。另外，is increasing的用法是错的，用increases 就可以了。

手机打字不方便，换电脑打。既然你还不明白，那我就整段修改一下吧，供你参考。
The amount of CH4 increases with the number of cycles due to an increase of the pressure-drop. From the perspectives of thermodynamics and kinetics, the increase of pressure-drop, or equivalently, the rise of the reaction pressure can promote reaction (8), which is a volume reducing reaction.
