昼夜动态 meaning in Chinese
diurnal dynamics
Examples
- ( 3 ) the diurnal observation results of soil co2 dynamics in the field display the variation of soil co2 concentration and the releasing rate of co2 coming from soil surface is controlled by temperature . the correlation between co2 concentration in the top soil and temperature is very significant
( 3 )土壤co _ 2浓度和土壤释放量昼夜动态变化均受温度控制。土壤co _ 2浓度中义摘要变化与温度相关分析结果表明，土壤表层co 。浓度的变化与温度相关性显著。 - But variation of the co ; concentration in the bottom soil show that sink effect of carbonate rock on the soil air co2 ( 2 ) the diurnal observation results of soil co2 dynamics in the different vegetation show that the soil co2 concentration in the bare land is sensitive to environment , but the soil co ; concentration in the other experimental site , which covered with vegetation , restrain the variation
在土壤?大气界面上，土壤表层可为大气提供游离co _ 2 ；而土壤深部co _ 2浓度的变化则显示下覆碳酸盐岩对co _ 2有吸收作用。 ( 2 )在不同植被系统中，土壤co _ 2昼夜动态变化进程不同。观测资料表明：裸地对外界环境的变化相当敏感，而有植被覆盖的竹林和草甸对土壤co _ 2浓度动态变化有平抑作用。 - The research include : 1 ) measuring co2 concentration in the soil air and vegetation air by using co2 measuring instruments ; 2 ) measuring the releasing rate of co2 coming from soil surface by using alkaline absorbing method ; 3 ) measuring the hydrochemical indexes of soil water . the research results are as follows : ( 1 ) the author has made field observation of depth distribution of soil air co2 in the mt . jinfo karst experiment site . the results show that two concentration gradient , soil to atmosphere and soil to carbonate rock , are form
本次实验以典型的亚热带岩溶分布区?金佛山自然保护区为例，选择了岩溶洼地内的高山草甸和靠洼地边缘地带的方竹林、裸地以及石林内的乔木林4个样地，对土壤co _ 2浓度空间分布规律以及昼夜动态和日动态变化状况进行了观测，获得了如下新的认识： ( 1 )土壤中co _ 2浓度分布的观测结果表明，土壤中具有土壤-大气、土壤-碳酸盐岩两个方向的co _ 2浓度梯度。
