元素浓度 meaning in Chinese
element concentration
Examples
- The spatial distribution of element concentration values is expressed in the form of map .
元素浓度值的空间分布应以图的形式表示。 - Research of inorganic element concentration in different diameter particulate in wusong area of shanghai
上海市吴淞地区大气不同粒径颗粒物无机态元素浓度分布 - It shows that the absorption of cu and pb for clover tend to increase gradually with the increased concentration of relevant elements in soil under experiment , but cu and pb display obvious restraining effect
结果表明，生长一个月左右的三叶草对铜和铅的吸收在实验条件下均随土壤中相应元素浓度的增加而增加，但铜和铅之间存在着明显的拮抗作用。 - 2 ) from the analysis of the aerodynamic parameters and turbulent flux transfer under different synoptic conditions we achieve the conclusion that on sands raising and sandstorm days turbulent momentum and sensible - heat fluxes are important exchange factors in the boundary layer , with turbulent exchange stronger in sandstorm weather than both on fine and sand raising days . prior to the occurrence of such an event , in particular , the super - adiabatic instability in the near - surface boundary will reinforce sandstorm weather condition . 3 ) atmospheric turbulent diffusion parameters z and y have apparent daily variation
沙尘天气下以亲地壳元素为主的气溶胶元素浓度均高于背景大气和浮尘天气，而且沙尘天气强度愈强，元素浓度的增加愈显著；背景大气、浮尘天气条件下亲地壳元素的浓度一般在10 ~ ( - 1 ) 10 ~ 0 g m ~ 3量级，扬沙、沙尘暴时一般达10 ~ 1 g m ~ 3量级，特强沙尘暴时高达10 ~ 2 g m ~ 3量级。 - Eight heavy metal elements are measured under atmospheric background and dust - sandstorm weather conditions . element - concentration under dust and sand storm is as higher 3 . 43 - 6 . 30 times as background . six heavy metal elements in precipitation are also analysed and its sharp variation geographically are found
分析了大气背景和沙尘天气下的8种重金属元素浓度和降水中的6种重金属元素浓度，结果表明，沙尘天气重金属元素浓度是背景值的3 . 43 - 6 . 30倍，降水中6种重金属元素浓度的地理分布存在不均匀性
