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

如果是一颗小行星， 能不是一个紧迫的问，能是一个有影响的问， 甚至是一个消的问。

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.

电流镜的移动相对较，们能需要慢一点，这取决于烧蚀所需的材料的反射率。

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的能量输出，这里只有 15 瓦特，有助于确保我们没有烧蚀掉材料。
