查询词典 exponential law

The test results show that both the permeability of sandstone and that of granite with a single fracture declines with the increasing effective pressure, following the law of exponential decay. The permeability sensitivity of granite with a single fracture to effective stress is much stronger than that of sandstone, but the recovery capability of permeability of sandstone is more stronger than that of granite with a single fracture.

试验结果表明，在围压升降过程中，砂岩和单裂隙花岗岩的渗透率均随有效应力的增加呈负指数规律减小，但单裂隙花岗岩的渗透率对有效应力的敏感程度远大于砂岩，而砂岩渗透率的恢复程度则远大于单裂隙花岗岩。

In this study, for the complicated distribution of dose rate in time and space, considering the repair of the sub-death cells, the radionuclide decay law and exponential proliferation of clonogenic cells, the dose-response relationship is built based on the known linear-quadratic model, and the concept of tumor control probability is introduced into the therapy method.
