大气中氧 meaning in English
aerial oxygen
Examples
- As the atmosphere slowly became rich in oxygen, life changed to take advantage of oxygen as a source of energy .
随着大气中氧慢慢地增多，生命也就变得喜欢用氧作为自己的能源。 - Life ' s long journey from single - celled organisms to multicellular plants and animals may have depended upon the increasing presence of oxygen in the atmosphere , a new study suggests
一项新的研究表明，地球生物从单细胞的有机体一直发展到多细胞的植物和动物这样一个漫长的旅途很有可能依赖于大气中氧含量的增加。 - Thirdly , tio _ ( 2 ) thin film has the good properties of sensitiveness on gas , which can make thin film sensor to test the tail gas of car , the oxygen content in the air and the leakage hydrogen
作为气敏膜，用它制备的传感器可用于汽车尾气及大气中氧含量的检测，氢气的泄露检测等，而且使用寿命长，不易中毒。 - In section one , by using fice scheme and time - gcm , a model of trace gases and oh airglow affected by gravity wave is set up , then the propagation of nonlinear gravity wave and the effect on trace gases and oh airglow are analyzed . the result shows gravity wave excited by tropospause forcing can propagate stably to the mesosphere through the stratosphere so that energy and momentum can be transferred from one region to another . in this process , gravity wave undergoes growth , overturning , convection and breaking
在第一部分的工作中，利用全隐欧拉格式和全球热层-电离层-中间层-电动力学环流耦合模式（ time - gcm ） ，对重力波的非线性传播及其在传播过程中对中高层大气中氧族和氢族成分和与之密切相关的oh气辉辐射的影响进行了数值模拟，结果表明，从对流层向上传播的重力波经历了产生、发展、饱和、对流产生直至破碎的非线性演化，大气的非等温结构加速了重力波在中层顶区的破碎，重力波的非线性传播是小尺度对流和湍流产生的一个重要的源。
