learning how to draw them 在学如何画他们
It is explained in this paper what the velocity component contours in slip-line-field are and how to draw them.
本文论述了滑移线场中理论速度分量等值线的概念及作法。
He covers fingers and toes in detail, demonstrating how to draw them flat and in foreshortened perspective from multiple angles.
该教程详细介绍他的手指和脚趾,演示如何从多个角度来看这些单位和透视。
However, they also rely on "integrity management programs" that require companies to draw up their own plans to assess risks like leaks and corrosion, and how to address them.
然而,他们也依靠“完整性管理计划”,也就是要求受检公司拟定他们自己的计划,以此评估诸如泄漏和腐蚀之类的风险以及如何应对风险。
And, we'll tell you all you need to know except for how to draw them.
我会对他们一一详解,然不包括怎么去画。
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。
Once you're doing this on your own, -- especially, for example, on exam 2, which is a ways down the road, you won't be able to look at those steps, so you need to make sure that you can go through them without looking at them, but for now we can look at them as we are actually learning how to draw the Lewis structures, and rather just go through them step-by-step, it's more interesting to do it with an example.
每当你要画一个路易斯结构的时候,特别是,比如,在第二次考试中,在不远的将来,你将看不到这张表,因此你需要确保自己在不看这张表,的情况下也能按照上面的流程来画,但是目前我们是可以看着这张表,来学习如何画路易斯结构的,而相比于一步一步地讲,通过例子来演示一下会更有意思。
