例如，“裂解”在催化剂和加热下，将大分子的碳氢化合物破坏成小的。

For example, "cracking" involves breaking larger hydrocarbons into smaller ones with either heat or catalysts.

因此，把质子结合到更可极化的气体上，会释放很多能量，利于成键。 当然，这要求有小的、电负性的共配物。

Attachment of a proton to the more polarizable gases therefore gives significant energy toward bonding.

蔗渣磨木木素在隋性气体氛围下，热化学裂解形成大量含苯环的木素基本结构单元衍生物，部分进一步降解成小分子化合物。

The result indicated that MWL was degraded to lots of basic structure unit ramifications contained phenyl of lignin, some of which were decomposed to compound of small molecular weight.
