非局部的

The result indicates that the reconstruction based on differentiable basis function is better than that based on non-differentiable basis function and the reconstructions based on different differentiable basis function is approximately the same.

结果表明，对于少数投影计算机层析重建，采用连续可导的局部基函数展开比采用非连续可导的脉冲基函数展开具有更高的重建精度。

E.g. control exposure to fume by local exhaust ventilation rather than personal respirators ; adapt ing to technical progress and changes in information ; seeking to ensure an improvement in the level of protection.

例如利用局部排气系统而非个人呼吸辅助器以控制烟雾的危害；随著技术发展和资讯的更新，调整做法；确保防护等级的提升。

Secondly, a rule of the choice of step-length is presented for a non-quadratic objective function of n variables, according to the rule we prove that the Gradient Method has local n-step quadratic convergence rate for a non-quadratic function under certain conditions.

其次，对于n个变量的非二次目标函数也提出了一个步长选取的准则，并在此准则下证明了当目标函数满足一定的条件时，梯度法具有局部n-步二阶收敛速度。

Base on the Fluent software,the time-average N-S equation,RNG k-ε turbulence modeling,P1 radiant modeling and particle track modeling,example for boost motor PQM-1 of Titan 4,by using flow-solid coupling boundary condition,the 2D axial symmetry gaseity fluid modeling and two phase fluid modeling were founded and the influence of coagulate particle to the flame-spread process in large aspect ratio SRM ignition transient were analyzed.

0引言固体火箭发动机点火过程是点火燃气流动与火焰传播相互耦合的过程，即包括点火燃气流动、药柱加热、局部点燃、火焰传播、室压建立等复杂的非定常过程，其中火焰传播在点火瞬态过程中占有重要地位，是发动机点火延迟、压强峰值过高、断续燃烧和熄火的主要因素，因此国内

Therefore,it can be used as an effectivemethod to study the local coordination environment of metal ions in biologicalsamples of noncrystalline or low concentration,which cannot be done with X-ray and NMR techniques.

因此它可以作为一种研究低浓度、非晶态生物样品中金属离子的局部配位环境的有效手段，发挥X-射线衍射技术和核磁共振技术所发挥不到的作用。

The aim of our work is to strengthen localized features in basis images and to impose orthonormal characteristic of Principle Component Analysis on NMF.

我们的目标是强化基底的局部特徵，以及将主轴分析演算法的正交特徵加在非负矩阵分解演算法上。

The large displacement movable boundary in chemical reaction flows was simulated by the combination of spring method and local remeshing method. Spring method was sufficient for relative small boundary displacement; local remeshing method was used to deal with large boundary displacement.

采用弹簧方法和局部网格重构法相结合的动网格技术实现了快速、优质地模拟化学非平衡流场中边界的大位移运动，为了克服网格变形或重构引起的质量不守琚A采用积分重映求取新网格上流场状态参数。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
