Krypton in today「s atmosphere is somewhat heavier than solar krypton, and the krypton embedded in meteorites known as carbonaceous chondrites is even heavier than that.
氪在今天的大气层中比太阳能的氪更重一些,这些氪比埋入了陨星,也就是通常熟知的碳质球粒状陨石中的氪还有重很多。
Argon emitted blue and green light, krypton several other colours, and mixing the two gases made a laser that could emit across the visible spectrum.
氩气产生蓝色和绿色的光,氪产生其他几种颜色,两种气体的混合可以产生整个可见光谱中的颜色。
K. Neon, argon, and krypton are obtained from fractional distillation of liquid air.

「They assume that since they don」t see solar-type krypton today in this one reservoir, that it was never there,」 Pepin says.
Pepin说:「他们假设因为他们没有在一个观察对象中看到今天的氪气,就觉得这种氪气也不存在于气体观察对象之中。」
The operation theory of violet lasing in krypton ion laser and the construction design of the plasma tube are discussed.
本文讨论了氪离子激光器中紫色激光作用的工作原理,放电管的结构设计。
In particular, the researchers were studying the isotope ratios — or the comparative abundances of the different forms of a particular element — of the gaseous elements krypton and xenon.
特别值得一提的是,研究人员研究了氪和氙两种气体元素的同位素比值。同位素比值是指一种特定元素中各种同位素之间的丰度之比。
After they are sealed up, krypton and argon gasses are pumped into the space in between.
当它们被密封之后,就向其中注入氪气和氩气。
The krypton and xenon isotope ratios in the gas samples provided a surprising result: They did not match the ratios found in the primordial cloud that spawned the solar system.
气体采样中的氪和氙同位素比值产生了一个令人吃惊的结果:这些比值跟在形成太阳系的原始云团中所发现的比值不一致。
With pressure and electricity, the laser creates dimers by passing electrical current through mixtures of reactive gases, such as fluorine or chlorine, and inert gases, such as krypton or argon.
用压力和电能,所述激光通过使电流通过反应性气体,如氟或氯,和惰性气体,如氪或氩气的混合物产生二聚体。

介绍了医用YAG激光机的维修经验。着重叙述了氪灯电路的修理和光路的调整。
So, selenium 2 minus is what「s going to be isoelectronic, because if you add two electrons to selenium, you」ll get the same electron configuration that you have for krypton here.
负二价的硒离子将是等电子的,因为如果你给硒原子加上两个电子,你会得到,和氪原子相同的电子排布。
Neon, argon, and krypton are used in lighting.
