实验室水平的吸附式天然气（ANG）储气只需用CNG约1/6的压力即可达到其3/4的体积能量存储密度。

The volumetric storage density of ANG can be 3/4 of CNG at 1/6 the gas pressure in laboratory research.

形成黑洞的关键环节，就是要像脉冲星崩溃时出现的情况一样，把足够大的质量或能量压缩到足够小的体积。

The key to forming a black hole is cramming enough mass or energy into a small enough volume as happens when a massive star collapses.

因为电池能存储的总能量依赖于它电极的体积，一个小的电池是不能长时间供电的。

The amount of energy a battery can store depends on the volume of its electrodes, so a thin battery does not last long.

In other words, if we don't have to worry about entropy or volume equilibrium is achieved when energy is at a minimum.

换句话说，如果我们不担心熵,和体积的平衡,那么能量就得是最小的。

I mean, if the energy is lower to occupy a smaller volume, then if I have this room and a bunch of molecules of oxygen, and nitrogen and what have you in the air, and there are weak attractions between them, why don't they all just sort of glum together and find whatever volume they like.

我的意思是，如果占据小的体积会使能量降低，如果我有这样一个空间,和一些氧气，氮气和其他空气中有的气体，并且分子之间还有微弱的相互作用，为什么他们不黏在一起,然后占据他们所想要占据的体积。
