They fill the container with pure air made by evaporatingliquid nitrogen and liquid oxygen, and add water vapour and some trace gases.
他们将容器充满由蒸发液态氮和液态氧得到的纯空气，再加入水蒸气和一些痕量气体。

Simulating results show that laminar, turbulent and wavy flow states are simultaneously subsisting in the evaporatingliquid thin-film, and turbulence appears in the arched wave before wipers.
模拟结果表明，蒸发液膜呈现层流、湍流、波动流等复杂流动形态，湍流主要出现在刮膜器前的弓形波内。
