You got to sublimate yourself, your ego and, yes, your identity.

你得升华你自己，你的自我，没错，还有你的身份。

The comet's ice begins to sublimate, or turn directly into gas.

彗星的冰开始升华，也就是直接变成了气体。

Of course, ice by itself can also sublimate, which is why ice cubes shrink in their trays over time.

当然，冰本身会升华，这是冰块在冰格里会逐渐缩小的原因。

Frost-flowers on sea ice, for example, form when water vapor sublimates from warm ice into air too cold to hold it.

比如，因冰中产生的水蒸气升华到空气中太冷而无法保持形态，从而在海冰面形成了霜花。

His actions were sublimated by his mind.

他的思想使他的行为升华了。

As solid CO2 sublimates in summer, it powers 400 kilometer per hour winds.

当固体二氧化碳在夏季升华时，它为时速 400 公里的风提供动力。

Or maybe it used to be one big lump, but over the eons the ice in the middle sublimated more, leaving behind the two lobes.

又或许它曾经是一个大冰块，但无数年后，其中间的冰升华得更多，留下了两个叶瓣。

We've visited comets up close and found them to be lumpy, with vents in the surface that release the gas as ice sublimates.

我们曾近距离观察过彗星，发现它们是块状的，表面有排气口，当冰升华时会释放出气体。

As the ice sublimates, the bits of rock and gravel and dust embedded in it can be freed and leave the nucleus as well.

当冰升华时，嵌入其中的岩石、碎石和灰尘也会被释放出来并离开原子核。

Most likely, these methane particles are uplifted  by sublimating nitrogen ice, the process by which a substance changes phase from solid to gas.

最有可能的是， 这些甲烷颗粒是通过氮冰升华而升起的，这是物质从固态相变到气态的过程。
