氩
1、一种无色、无臭的惰性气体元素,存在于空气中,占空气体积的0.94%,亦存在于火山气体中,从液态空气分离获得。主要用于金属加工和电弧焊接时作为保护性气氛,还用于白炽电灯和荧光灯泡、充气电子管以及盖革计数管作填充气体 ——元素符号为A或Ar。
像氖和氩这样的惰性气体,在它们的外电子层有8个电子。
Inert gases like neon and argon have eight electrons in their outer shell.
氯离子,与氩的电子数相同。
Chloride minus. Isoelectronic with argon.
氖、氩、和氪用于照明。
Neon, argon, and krypton are used in lighting.
氖、氩、氪都能够通过分馏液态空气获得。
K. Neon, argon, and krypton are obtained from fractional distillation of liquid air.
我们可以用氩离子。
We could use argon ion.
惰性气体氩离子清洗过程中使用。
Inert argon gas was used in ion cleaning processes.
人类没有能够探测到氩的存在的官能。
Humans possess no senses that can detect the presence of argon.
据实际情况采用锡或氩焊接。
According to the actual situation of tin or argon welding.
随后,氩作为低温液体运输。
The argon is then removed as a cryogenic liquid.
在定位焊时焊缝内侧应停止充氩维护。
At the position of the weld, the inner side of the weld should be stopped.
剩下的一些延迟消退的很慢,比如铯、碘、锶和氩。
Others decay more slowly, like some cesium, iodine, strontium, and argon.
记住,氩没有警告性特征!
Remember, argon has no warning properties!
氩属于稀有惰性气体家族。
Argon belongs to the family of rare inert gases.
如果它能得到另一个电子,它就能和氩一样是电绝缘。
If it could gain one more electron, then chlorine would be iso-electronic with argon.
他把那气体取名为氩。
He termed the gas argon.
所以如果我们谈论第3个周期,它从钠开始,一直到氩。
So if we're talking about the third period, that starts with sodium and it goes all the way up to argon.
气态氩无味,无色,无嗅,无腐蚀性,不可燃。
Gaseous argon is tasteless, colorless, odorless, non corrosive, and nonflammable.
目的评价氩激光在治疗视网膜裂孔中的应用效果。
Objective To evaluate the effects of Argon laser in the treatment of retinal hole.
氩是单原子气体。
Argon is a monatomic gas.
目的:探讨氩离子激光对视网膜裂孔的治疗效果。
OBJECTIVE: To assess the effect on argon laser in treatment of retinal holes.
即使使用氩和其它气体的混合气切割也会有粘渣倾向。
Even if use argon and other gas mixture of cutting will also have a viscous slag tendency.
很可能氪和氩也可以做路易斯碱,但显然它们不能和氟化氢竞争。
It is possible that Kr and Ar could also act as Lewis bases, but evidently they cannot compete with HF.
由于无嗅、无色、无味、无刺激性,氩没有警告性特征。
Since argon is odorless, colorless, tasteless, and non-irritating, it has no warning properties.
其它方法都无效的情况下,氩氦刀依然取得非常好的效果。
When other modalities become inefficacious , Argon-helium knife still can get very good results.
其中一些元素比较少见,但是从氩到锌的所有元素都存在于那些尘埃中。
Some elements were more common than others, but everything from argon to zinc was there.
你一不小心直视氦氩激光,暂停一轮并失去一只眼睛的视网膜。
You accidently stare at a helium-argon laser, lose one turn and a retina.
我们再考虑一次氩的s轨道,所以我们说我们在看氩的1s轨道。
Let's consider again an s orbital for argon, so let's say we're looking at the 1 s orbital for argon.
例如,火星上氩36与氩40之比,大致只有地球上的比率的九分之一。
For example, the ratio of argon 36 to argon 40 on Mars is only about one-ninth the ratio found on earth.
