Oxygen and strontium isotopes, which are fixed in dental enamel at the time of tooth formation, were tested in 18 subjects.
在18件样本上检测了氧和锶的同位素。这两种元素在牙齿成型时，会固定在牙釉质上。
Thus, distinguishes between two kinds of battery electrolyte "fixed" way and provide oxygen to the cathode channel differently, thus the performance of the two kinds of battery also.
由此看出，两种电池的区别就在于电解液的“固定”方式和提供氧气到达负极通道的方式有所不同，因而两种电池的性能也也。
The nitrogen Deoxo Vessel contains a fixed bed of free copper catalyst which removes oxygen from the nitrogen stream by oxidation of copper to copper oxides.
氮气脱氧罐中装有一个游离铜催化剂的固定床，通过将铜氧化成氧化铜把氧气从氮气中脱除。
This might partly be relative with the fixed, extra and highly concentrated oxygen vacancies resulted from Y3 + doping, the mechanics of which were as described in the solid state chemistry.
这应部分地与固体化学所描述的Y3 +掺杂所造成固定、额外并且是高浓度的氧空位有关。
