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

烧蚀物质在流星后面留下道发光痕迹，我们称之为“train”。

And if it's an asteroid it may not be a burning question, it might be an impacting question, or even and ablating question.

如果颗小行星， 可能个紧迫问题，可能个有问题， 甚至个消融问题。

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，但们可能需要慢点，这取决于烧蚀所需材料反射率。

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。
