当发动机的功率耗尽时，电池在10分钟内就会耗竭——如果连续不充电，它们还能靠化学反应支撑的话。

With the engine performing at full capacity, the batteries would be drained in the space of 10 minutes -- if they were even chemically capable of withstanding such a rapid discharge.

他们担心阿泰斯特会像以前一样桀骜不驯，并破坏这支刚刚获得总冠军球队中的化学反应。

They feared that Ron Artest would destroy the chemistry of a team that had just won a championship with his volatile personality.

浸出过程属于混合控制，即表面化学反应与通过不溶硅、铁矿物相的扩散为过程的控制步骤。

The leaching process is controlled by mixed steps:the surface chemical reaction and the diffusion passing through the silicon and iron mineral phases.

Versus looking at, for example, helium or neon or argon, these are all inert gases, inert meaning essentially do not react, those were grouped together in the periodic table.

相反，他发现氦，氖，氩，都是惰性气体，惰性的意思是基本不参与化学反应，因此把它们放在周期表中的同一类里。

I couldn't have told you, for example, if we look at a phosphate group, that that's going to be incredibly important in DNA, that it's also an incredibly important group when you're dealing with proteins and whether you're turning the function of a protein on or off.

怎么和化学反应相联系起来的，更不记得其它我更不感兴趣的规律,我不能告诉你，如果我们看磷酸盐,它们对于构成DNA十分重要,也是构成蛋白质的重要组份,它是否能打开或关闭一个蛋白质的功能。
