通常讲，具有更少的晶体缺陷，更光滑的外形、更高的晶体密度，则有利于降低炸药的感度，提高安全性。
Usually, if explosive particles have less crystal defects, more smooth surface, and higher crystal density, the explosives have lower sensitivities and better safety.
密度测量结果意味着这些物质一定是水晶，而被许多人珍视的钻石，实质是碳元素的单质晶体。 也就是说，那颗行星的大部分可能都与钻石类似。
The density means that this material is certain to be crystalline, that is, a large part of the star may be similar to a diamond.
这个密度意味着它一定达到了晶体的密度，也就是说，这颗星球的一大部分也许与钻石类似。研究者解释道。
The density means that this material is certain to be crystalline: that is, a large part of the star may be similar to a diamond, the team explained.
