Among its popular products were " negative- ion" sanitary pads that claimed to prevent menstrual cramping and cervical cancer.

最受欢迎的产品之一是“负离”卫生巾，声称可以预防经痛和宫颈癌。

Instead, the pressure arranged the helium and sodium into a kind of 3-D checkerboard pattern, forcing pairs of electrons to separate and basically hang out on their own in between the helium atoms, almost like a negatively charged ion without a nucleus.

相反，高压将氦原和钠原以类似3D立体棋盘的模式进行组合，强迫电对分开，基本上都单独悬浮于氦原之间，近似没有原核的负离。

Yes. High levels of polyatomic anions released in the atmosphere.

大量的多原负离进了大气中。

The negative ions are of help, but you could not produce such conditions. But the attempt to produce advantageous conditions is in itself of help in any case.

负离是有帮助，但你们产生不了这样的条件。但试图产生有利条件本身，在任何情况下都是有帮助的。

These particles contain both positive and negative ions within their own unitary system, for they are of course also units in themselves.

在它们自己的单元系统内，这些粒同时包含正离和负离，因为它们本身当然也是单元。

We got something! A huge release of anions.

有情况了 大量负离。

They're compounds made up of positive and negative ions, usually formed when an acid reacts with a base.

它们是由正离和负离组成的化合物，通常在酸与碱反应时形成。

You have positive ions, the protons, and you have negative ions, that's the electrons.

你有正离，也就是质，你也有负离，那就是电。

Researchers are still looking for practical uses for ortho-diethynylbenzene dianion.

研究人员仍在寻找邻二乙炔基苯二负离的实际用途。

The resulting positive and negative ions are held together by electrostatic forces a process called ionic bonding The repetitive order in which the shells are filled in each row means that elements in each column of the table.

形成的正离和负离通过静电作用力结合在一起，这个过程称为离键合。每行中电壳层依次填充的重复顺序意味着表格中每一列的元素。

Here's a video I originally titled, " Are Negative Ions Good For You? " Which is a question nobody asked ever.

这是我最初命名为“负离对你有好处吗？ ” 的视频，这是一个从未有人问过的问题。

So we get more of the earth's negative ions, or I love to hang out on my PEMF mat too.

所以我们能获得更多的地球负离，或者我喜欢躺在我的脉冲电磁场垫上。

668. It gives off negative ions.

668. 它负离。
