累积限制控制允许的数据流数量和总速率。
Aggregate limits control the total rate for and number of data flows allowed.
此后，总速率由颗粒外表层内的扩散速率决定，符合一级动力学微分方程。
Hereafter, the general rate is determined by the diffusing rate in the exterior surface layer of the particle, which accord with lst-grade dynamic differential equation.
实验结果表明，从开始到吸附量达一定数额这段区域内，总速率由界膜内的扩散速率决定，且为一常数。
The experimental results show that, in the range from the beginning to a certain amount of adsorption, a general rate is decided by the diffusing rate in the scope film and it displays a constant.
