The shortage of B-stability brings some substantive difficulties to their quantitative convergence analysis.
稳定性的缺少给此方法的定量收敛分析带来了实质困难。

The turbulence eddy viscosity was simulated by B L model and region time steps with the multigrid techniques being used in the code in order to accelerate the convergence.
计算程序使用分布体力方法模拟粘性，用局部时间步长和多重网格方法加速收敛。

Moreover, we discuss the convergence for randomly weighted sums of B-valued martingale difference series.
