Then we'll talk about engineering of DNA and why this has been such - not only a rapidly growing and advancing area but one that's so important for Biomedical Engineering.

然后我们会谈论DNA工程,以及为何它不仅,是一个向前飞速发展的领域,而且对生物医学工程十分的重要

All right, so one thing that I want to point out, which I said many, many times on Friday, and this is perhaps the last time I'll say it, but one last time is we can think about why we only see a line for the 2 p orbital, versus we don't see separate lines for a 2 p x, a 2 p y, and a 2 p z.

好的，我还要指出一个问题，这个问题我在上周五已经说了很多很多次了，这可能是我最后一次提到它，但是这最后一次让我们来考虑一下,为什么我们只看到了一条，对应于，2，p，轨道的线,而不是分别对应于，2，p，x，2，p，y，2，p，z，的线？
