the simulated result indicated that the retardation factor (rd) of 3h was about 1.
模拟结果表明,3h在饱和黄土中迁移的延迟因子约为1。
both simple random sampling and latin hypercube sampling were applied to simulate the model of the soil retardation factor of the herbicide mefenacet by monte carlo method.
采用简单随机抽样和拉丁超立方抽样两种不同方法对除草剂苯噻草胺的土壤滞留因子模型进行蒙特卡洛模拟。
the moving boundary is introduced to indicate the notable change in the clay retardation factor with the increase of solute concentration.
模型引入了移动边界以说明当溶质在粘土孔隙水中的浓度达到某一较高值后,阻滞因子将发生显着变化。
but the mental factor, retardation factor and total negative factor lower than non-smoking patients (p0.05).
