It is major work to present the tectonic time duration system of the strain rate method, which is an original exploration.(1) Principle: Its basis is the stress and strain rule depending on strain capacity in steady-state stress field, but not the radioactive decay law depending on radiation dose in invariable radiation field. This can be simplified as a process of differential stress-strain rate-strain capacity-time duration calculating.
工作重点是梳理出应变速率法构造时限定年系统，属原创性探索：①原理：不是基于放射性核素衰变规律，而是基于应力应变规律；不取决于恒定辐射场的辐射剂量，而取决于稳态应变场的应变量，可简括为差异应力-应变速率-应变值量-计算时限的求索过程。
