收敛

The authors investigated the singular limits of stiff relaxation and dominant diffusion for general 2×2nonlinear systems of balance laws, that is,τ=o,ε→ 0, the relaxation time τtends to zero faster than the diffusion parameter ε. If there exists a priori L∞ bound that is uniformly with respect to ε for the solutionsof a system, then the solution sequence converges to the corresponding equilibrium solution of the system.

研究一般扩散占优的2×2双曲平衡律系统奇异松弛极限，用补偿紧性方法，在松弛时间τ比扩散系数ε趋于零快时，即τ=o，ε→ 0时，得到其解的整体存在性一般框架：如果上述系统的解存在对ε一致的先验L∞估计，则其解序列收敛于上述系统的对应平衡状态解。

This algorithm does not need either a priori knowledge or a posteriori probability, and has convergence with excellent stability.

In this paper, a new kind of T2 axiom called strong T2 separation in topological systems is introduced. Characterizations of T2 separation by net convergences and by filter convergences are given.

Based on the tree martingale decomposition theorem and the con-vergence of locally finite tree martingales,a tree martingale convergence theorem isverified.

再基于树鞅分解定理和局部有限树鞅收敛定理，证明了一个树鞅收敛定理。

Moreover,in the light of constructingan one-to-one mapping which preserves ordering,it is shown that each locally fmitetree martingale is isomorphic to a Cairoli-Walsh martingale,and in virtue of which,the convergence of locally finite tree martingales is shown by the use of Cairoli-Walshmartingale theory.

进一步，通过构造一个保序一一映射，证明了每个局部有限树鞅同构于一个多指标鞅(Cairoli-Walsh鞅)，这就在树鞅与多指标鞅(Cairoli-Walsh鞅)之间建立了联系，接着利用这种联系与Cairoli-Walsh鞅收敛理论证明了局部有限树鞅收敛定理。

The hyperfine effects emerging in all spectra of atomic Rydberg states are due to the nuclear effects including hyperfine structure and isotope shifts. The autoionizing Rydberg states converging to 6p〓 and 4f〓 5d6s 〓 [3/2] 〓 limits were investigated by three photon excitation. In the study of the spectra for those converging to 6p〓 limit, the ICE (Isolated-core excitation) model has been proved to be suitable for describing the excitation of the autoionizing Rydberg states with a lowly excited core.

Under the given project scheduling specified by the upper-level algorithm, combined with a critical chain-based heuristic, the lower-level genetic algorithm reallocates the resources to shorten the project duration so that the rate of converging to the global optimum district is improved, and a variable mutation probability is developed to avoid premature convergence.

在由上层算法确定的调度顺序下，下层遗传算法结合基于关键链的启发式算法，对系统资源重新优化配置，使算法加速向最优解区域收敛，并在下层设计了随迭代代数增加的可变变异概率，以避免早熟收敛。

A large difference exists between the convergence of the results with and without taking account of autoionization resonance broadening when the autoionization resonance broadening is the major broadening mechanism.

研究中考虑与不考虑自电离共振展宽，对x-射线透射谱计算的收敛速度大不一样，考虑了此效应，收敛速度快很多，而且得到的透射谱与实验测量谱符合更好。

They weren't aggressive, but I yelled and threw a rock in their direction to get them off the trail and away from me, just in case.

他们没有侵略性，但我大喊，并在他们的方向扔石头让他们过的线索，远离我，以防万一。

In slot 2 in your bag put wrapping paper, quantity does not matter in this case.
