增强骨骼。苹果和苹果汁富含矿物质硼。硼的摄入可以增强骨质,有效防御骨质疏松症。
Strengthen bones. Apples and apple juice contain the mineral boron, which has been shown to strengthen bones-a good defense against osteoporosis.
室温形变可使渗硼的动力学过程加速。
Room temperature deformation can accelerate boronizing dynamic process.
论述了从卤水中回收硼的试验研究情况。
So in the case of boron here, what we're starting with is the ion, and now we're going to pull one more electron out.
那么在硼的情况下,我们应该从这个离子开始,现在我们要再拿走一个电子。
So, if we want to think about what the first ionization energy is of boron, what you want to do is write out the electron configuration, because then you can think about where it is that the electron's coming out of.
如果我们要考虑,硼的第一电离能,你首先要做的是写出它的电子排布,因为在这之后,你才能知道拿走的是哪里的电子。
So, we have beryllium in the first case here, it has four electrons, that's how we know it's beryllium, boron has five electrons.
那么我们将铍作为第一个例子,它有四个电子,这也是我们为什么能知道它是铍的原因,硼有五个电子。
