修匀

The discrete curvature vector based method to fair mesh by modifying vertex positions We first low-pass filter the discrete curvature vector function to make it change more gradually and uniformly, and then modify the vertex positions according the resulted function to improve the fairness of mesh.

以此为基础，给出了两个算法：网格改点光顺的离散曲率向量法基本思想是先用低通滤波算子修匀曲率向量，并由此修改顶点的位置以改善网格的光顺性。具体算法吸取了优化问题中Zoutendijk可行方向法的基本思想。

Also using the experience life table (2000~2003) of our country's insurance business to compare with the smoothing results.

并结合目前我国刚刚投入运行的人寿保险经验生命表（2000～2003），比较修匀结果。

Not only the shortcoming that the smoothing constant and order of the model are not changed for the exponential smoothing model during the process of prediction has been overcome, but also the theory of threshold model has been further developed.

这不但克服了指数修匀模式在预报过程中修匀常数和模式形式一直不变的缺陷，也进一步发展了门限模式的理论。

This paper sets up an optimal model to calculate the design flood hydrograph based on similar principle and uses particle swarm of cross operator optimization algorithm to solve it.

针对设计洪水过程线同频率放大法中手工修匀的不足，提出采用计算机优化方法实现洪水过程的自动放大。

The original data of age and sex specific constitution of population from the four censuses of China after smoothed by moving mean are ultilized to analyse the change of two sex age specific survival rates and their difference during intercensal periods and age specific sex ratios of each census at older ages.

本文选用我国4次全国人口普查资料中分年龄性别人口构成的原始数据经移动平均修匀后分析了两性高老龄各年龄队列人口在相邻普查期间的生存率及其差异随龄变化，以及每次普查人口高老龄组年龄别性别比。

We use Hodges-Lehmann statistic to do significance test for those factors. The multiplication model is applied in the quantitative analysis and weighted least squares method is introduced to solve the multiplication model. Although the matrix of coefficients is not of full rank and the solutions of the multiplication model are not unique, we prove that all those solutions are equivalent in some sense.

本文用Hodges-Lehmann统计量对风险因子作显著性检验，将乘法模型用于数据修匀和风险因子的定量分析中，并提出了用加权最小二乘法求解风险因子的风险度量，在系数矩阵不满秩、解不唯一的情况下证明了所有解在某种意义下的等价性。

As the use of the depicting, the problems of smoothing and perturbation of reliability function are studied.

作为这种刻画的应用，讨论了可靠度函数的修匀和摄动问题。

Sinceβkernel is non-symmetric, there will be problem in the precision of graduation if using kernel graduation method, because, generally, kernel function is supposed to be symmetric in kernel graduation method, thus will cause boundary deviation in actual application.

但β核为非对称核，如果使用核修匀方法，在修匀精度上仍会存在问题，因为一般核修匀方法中均假设核函数具有对称性，在实际应用中将导致出现边界偏差现象。

Symmetric kernel graduation ; non-symmetric kernel graduation ; Gamma kernel ; boundary bias

对称核修匀；非对称核修匀； Gamma核；边界偏差

Non-symmetric kernel density estimation is first used for life-table graduation in order to solve boundary bais of symmetric kernel used in the standard kernel density estimator,and compare the symmetric kernel graduation with non-symmetric kernel graduation and obtain the satisfied result.

针对以地称核修匀方法存在着边界偏差这种现象，将非对称核密度估计用于生命表数据修匀中，提出了非对称核修匀方法，并与对称核修匀方法进行比较，得到了令人满意的结果，从而使核修匀方法得到了进一步的推广。

For a big chunk of credit-card losses; the number of filings (and thus charge-off rates) would be rising again, whether
