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. 通過(guò)仿真分析，比較兩套阻尼系統的仿真結果，可以看出雙慣導水平阻尼能夠顯著(zhù)降低外速度誤差的影響，抑制經(jīng)度誤差。
The phase velocity dispersion and the numerical phase velocity errors ofelastic wave staggered-grid high-order difference method in anisotropic medium havebeen studied. 研究了各向異性介質(zhì)中彈性波動(dòng)方程交錯網(wǎng)格高階差分法求解的數值相速度色散和數值相速度誤差。
