查询词典 exponential

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.
