The material on the surface vaporizes and blows away — a process called ablation.

其表质随之蒸发并被吹走——这一过程被称为烧蚀。

Experts say most of the eight-ton craft would have burnt off in its rapid descent.

专家称这个八吨重航天器多数部件将在快速下降过程中烧蚀销毁。

That ablated material leaves a glowing trail behind the meteor, which we call a " train" .

烧蚀质在流星后留下一道发光痕迹，我们称之为“train”。

The goal here is ablation, which is a fancy word for removing material from the surface of something.

这里目标烧蚀，这一个花哨词，表示从某表去除材料。

This method is called laser ablation, and it was first developed in the 1970s to get something called black crust off marble.

这种方法被称为激光烧蚀，它最初在 20 世纪 70 年代开发，目从大理石上去除一种叫做黑色外壳东西。

The low rate of ablation also means that this is great for pushing debris and dust out of the way, almost like a broom.

低烧蚀率也意味着这非常适合将碎尘推开，几乎就像扫帚一样。

Dropping the pulse width in conjunction with lower energy output, just 15 watts here, helps to make sure that we aren't ablating away the material.

降低脉冲宽度加上更低能量输出，这里只有 15 瓦特，有助于确保我们没有烧蚀掉材料。

Most of the spacecraft's components burned up during the re-entry, and a small amount of debris fell into the predetermined safe waters of the South Pacific.

货运飞船绝大部分器部件在再入大气层过程中烧蚀销毁，少量残骸落入南太平洋预定安全海域。

The galvo mirrors are moving relatively quickly, but they may need to be slowed down a bit, depending on the reflectivity of the material in order to ablate it.

电流镜移动相对较快，但它们可能需要慢一点，这取决于烧蚀它所需材料反射率。
