The adsorption time of coal sample has a positive correlation with gas content and fracture growth.
样品的吸附时间与煤层含气量及裂隙发育程度呈正相关关系。
By this model, the effects of adsorption time, concentration of chloroform in drinking water and film thickness on the adsorption efficiency were discussed.
应用此模型研究了萃取时间、水样中氯仿的本底质量浓度和高效有机吸附膜厚度等对萃取效率的影响。
The experimental results show that, with the increase of adsorption time and desorption time, the product purity increases rapidly, and then decreases, including a optimum point;
实验结果表明：随着吸附时间和解吸时间的增加，产品气纯度先升高后下降，存在一个最佳的吸附时间和解吸时间；
