By tracking this ratio over time, he can determine how long gas has taken to reach the surface and gain clues to the chemical, thermal, and mechanical state of the rocks the gas is passing through.
通过追踪该比率随时间的变化，他可以确定氡气到达地表需要花费多长时间，同时获得气体所通过的岩石的化学、热力学和机械状态。
The result shows:The reaction time for using of the oxide was shorter and the ratio surface of the super-thin oxide was smaller.
结果表明：利用微波加热技术制备的超细氧化物所需反应溶液的浓度低、所用的反应时间短、比表面积大。
The effects of different temperature, time and the ratio of solid to solution on the extraction yield of Ganoderma lucidum polysaccharides (GLP) were optimized with response surface methodology.
本研究采用响应曲面法对影响GLP提取率的三个主要影响因素即提取温度、提取时间和液固比进行了优化。
