不幸的是，该方法能够导致无法预料且不精确的结果。

Unfortunately, that method can yield unexpected — and inaccurate — results.

这种被称作“中子激活分析”的技术甚至能对微小的样本提供精确的结果。

Known as "neutron activation," the technology provides precise results, even on tiny samples.

任何WOC系统的界定元素是，它有越多的参与者，就能得到越精确的结果。

A defining element of any WOC system is that the more participants it has, the better it gets.

So that means that we don't have to worry about things like wave functions when we're talking about Lewis structures, but because they're so simple to use and because they so often predict the electron configuration of molecules accurately, we end up using them all the time in chemistry, so it's very valuable to know how to draw them correctly and to know how to work with them.

因此这也就意味着我们在讨论路易斯结构的时候,不需要担心波函数之类的东西，但是由于路易斯结构不仅简单易用,而且用它来预测分子的电子排布,经常可以得到非常精确的结果，结果我们在化学中一直都在用它，因此知道如何正确地画出并运用,路易斯结构是非常有价值的。
