1. The simulation results show that the level damp of DINS can reduce the influence of the external velocity error, and restrain the error of longitude effectively.
   通过仿真分析，比较两套阻尼系统的仿真结果，可以看出双惯导水平阻尼能够显著降低外速度误差的影响，抑制经度误差。
2. The phase velocity dispersion and the numerical phase velocity errors ofelastic wave staggered-grid high-order difference method in anisotropic medium havebeen studied.
   研究了各向异性介质中弹性波动方程交错网格高阶差分法求解的数值相速度色散和数值相速度误差。
