The kinetic curves properties response aging time and temperature were obtained with the coefficientof compression stress relaxation as index of aging property change.
用压缩应力松弛系数作为老化性能变化指标，得出了性能随老化时间和温度变化的动力学曲线。

During form-finding of catenoid, when the viscosity coefficient was not more than0.7, the dynamic relaxation method taking damp into account had good convergence and the nodes distributed more even.
对悬链面找形时发现，当黏性系数不大于0.7时，动力松弛法收敛，网格节点分布较无阻尼时均匀。

The study also goes to the influence, upon stress waves, of the piles relaxation time, the equivalent viscous damping coefficientof soil around the pile and the unit rigidity of soil below the pile.
