In this, the gas stream coming in, about 6% of the content is CO2.

在这里，气体会流进来，大约6%的含量是二氧化碳。

During this process, an electric current passes through the gas, creating an electric arc, which moves in the direction of the gas stream while the arc length lengthens.

在此过程中，电流通过气体，产生电弧，电弧在气流方向上移动，同时电弧长度也随之变长。

Not only does a gas stream contain water vapor that can freeze by itself, that water vapor can also combine with hydrocarbons to create hydrates that solidify at temperatures well above freezing.

气流不仅含有可以自行冻结的水蒸气，而且该水蒸气还可以与碳氢化合物结合形成水合物， 该水合物在远高于冰点的温度下凝固。
