1.The cell-centered symmetric finite volume arithmetic and Runge-Kutta time stepping scheme are performed to solve Euler equation. The two order and four order artificial dissipation is introduced for stability, local time stepping and implicit residual smoothing technique is applied to save computer time.
在求解Euler方程方面，采用格心格式的有限体积法进行空间离散，四步Runge-Kutta法作时间推进，二阶、四阶人工耗散作为稳定措施，还采用当地时间步长和隐式残值光顺提高收敛速度。收藏指正
2.The Newton-Raphson increment iterative method is adopted with accelerating convergence technique as line search, DOF predictor, and automatic time stepping.
计算时,采用Newton-Raphson 迭代方法,并辅助了线性搜索技术、应用预测和自适应下降等加速收敛技术。收藏指正
3.That, of course, destroyed the embryos, so their technique is only a stepping stone to the desired outcome of working with a single cell from each embryo.
因此他们的新技术，只是实现仅用胚胎中的单一细胞就可以进行试验，这一目标的手段。收藏指正
