Well, that has to do with something called impedance matching.

嗯，涉及到个叫做阻抗匹配的概念。

And by the way, this impedance mismatch is exactly what you were talking about with regards to that server versus client rendering environment, right?

顺便提，阻抗不匹配正你之前讨论服务器与客户端渲染环境差异时提到的，对吧？

So in Swift 4, we have vastly simplified this by removing all this impedance, and now strings are range-replaceable collections of characters.

所以在 Swift 4 里，我们极大地简化了个过程，去除了阻碍，现在字符串以大范围替换字符集了。

So there's almost this impedance mismatch where developers come to using a function and then they expect that everything that they're used to in the Node.

所以里几乎存在阻抗失配，开发者开始使用函数，然后他们期望在Node.js世界中习惯的切都能开箱即用，失配有时就道小伤口。

This article presents an image reconstruction method for open electrical impedance tomography (OEIT) combined with inversion mapping and contour representation to address the profile and medium distribution measurement requirements of adhesion cavitation.

本文提出了用于开放式电阻抗层析成（OEIT）的图重建方法，结合了反转映射和轮廓表示，以解决粘附空化的轮廓和介质分布测量需求。

So by impedance matching, you give yourself a much larger area to push against all the air at the outlet, which makes for a more effective chain reaction of molecules crashing into your eardrum.

因此， 通过阻抗匹配， 你为自己创造了更大的面积来推动出口处的所有空气，使得分子撞击你的耳膜形成更为有效的连锁反应。
