A temporal and frequency domain analysis of the optical responses in tissue acted by ultra-short laser pulse ── dirichlet boundary condition and isotropic point source 超短激光脉冲作用下生物组织体光学响应的时域和频域分析&Dirichlet边界条件和无向点激励源
But to leakage accident, we can simulate the running of pipeline according to the boundary condition of start-point and end-point, the point of intersection of two pressure curve must be the leakage point. 而对于泄漏事故,分别利用起点和终点边界条件模拟管道的运行情况,两条压力曲线相交点即为泄漏点。
According to the mathematical model of saturated-unsaturated instantaneous seepage, the paper has considered the effects of different unsaturated parameters within an element and solved the problem of unstable calculation caused by sudden changes of boundary condition in a saturated zone by using the method of Gauss point. 本文根据饱和一非饱和瞬态渗流数学模型,采用高斯点法分析瞬态渗流问题,从而考虑了单元内非饱和参数不同的影响,解决了饱和区边界条件有突变时引起的计算不稳定问题。
" Love " and do not divide the national boundary, have no condition! Can decree by destiny only! The mind a point is for, mutual happiness satisfy. “爱”是不分国界,没有任何条件!只要能有缘分!心灵一点就通,互相快乐就满足了。
In boundary condition treatment of upper end imagination section, it is suggested that drilling tools under neutral point is regarded as subject investigated, making the problem simplified properly and small effect to computational accuracy. 在下部钻具组合上端假想截面边界条件的处理上,提出了以中和点以下钻具为研究对象,使问题得以适当简化,同时对计算精度的影响较小。
