If venting rates are fast (gas flux q>-0 kg/m-a) in the earlier stage of the seeping system, the vent gas has almost the same composition as the source gas, and the heaviest possible hydrates are crystallized at the surface.

在海底天然气渗漏系统演化的早期(高速渗漏，q＞～0 kg／m~-a)，海底渗漏天然气几乎具有与气源天然气一致的天然气组成、形成的水合物具有最重的天然气组成。
