| 中文摘要:用热活化技术 ,对兰州盆地庄浪河剖面野狐城组地层中石膏样品的g=2.004峰ESR信号进行了平均寿命的估算。实验结果表明 ,一级动力学方程可能不适于g=2.004峰ESR信号平均寿命的估算。研究中采用几种方法估算了g=2.004峰ESR信号平均寿命 ,并进行了比较。用双二级动力学双活化能模式估算石膏g=2.004峰ESR信号在20℃时平均寿命为2.22×108a。 |

| Abstract:The average life was estimated for ESR intensities of the sample at g =2.004 from Yehucheng strata along Zhuanglanghe section in Lanzhou Basin by thermal activation technique. The experimental results show that the first order kinetics equation is not suitable for estimating the average life in gypsum at g =2.004. The average life of ESR intensities at g =2.004 was estimated and compared by several calculation methods. It is about 2.22×10 8 years at 20 ℃,which was estimated by the model of two second-order kinetics equation with different activation energies. |
