Marine Oxygen-isotope stage 3 深海氧同位素三阶段
At 3, 776m the mountain is high enough to cause altitude problems, and we were not alone in being grateful for oxygen later on.
富士山顶海拔3 776米,足以引起高原反应,我们也不是后来仅有的使用了氧气的人。
Most species prefer a micro-aerobic atmosphere (containing 3-10% oxygen) for growth.
多数菌种喜欢微氧生长环境(含3-10%的氧气)。
Like the 1-2-3 phase material, the oxygen content not only influences the phase, zero-resistance temperature of the sample, but also influences the transport property of normal state.
如同1-2-3相材料一样,氧含量不仅影响样品的成相规律、零电阻温度,而且还严重影响其正常态的输运性质。
So oxygen gets 3 pairs, and each chlorine gets 3 pairs, so now we're up to 9 pairs.
那么氧都有三对,每个氯有三对,那么现在我们用了九对了。
Well, oxygen, we'll put a hydrogen here, 1 2 3 4 hydrogen here, and one, two, three, four.
如果把一个氢放在这边,另一个氢这边,然后。
So it's going to be a sigma bond, 1s and we have oxygen 2 s p 3 and hydrogen 1 s.
它是sigma键,我们有氧2sp3和氢。
