The results indicate that the reconstructed quintic spline curve can ensure the cutter transit well for corner contour, and that the cutting performance is superior to that of the quadratic one.

同时也重构了一条四次样条曲线与五次样条曲线作对比分析，结果表明，五次曲线能使裁刀获得良好的且较四次曲线优越的轮廓拐角加工性能。

与假定辐射效率为常数的模型对比，结果表明辐射效率的变化对黑洞质量的增长有较明显的影响，使黑洞的增长延迟。

First, we have proved that the constraint of local constant gradient angles is equivalent to the minimization of total variation. Based on this, a stronger continuity constraint of gradient angle is presented. The interpolation formula (a 3-degree-PDE) derived from the constraint can ensure the continuity of level lines and reduce the width of edges. The contrast invariant of the regularizer of the formula is also proved.

首先证明了局部恒定的梯度角约束插值等价于总变分最小化；在此基础上，提出一个具有更强连续性的梯度角约束，由这个约束条件导出的三阶偏微分方程使插值的图像既可以保证水平线方向的连续性，又减小图像边缘的宽度；最后证明了插值方程中正则项的对比不变性。

Analysis of performance for five research schemes indicates that the residue is the main structural feature in this peptide system, and residue characterization can be used to describe the entire peptide. This will make characterization simpler and more efficient.

通过对五种表征方案进行对比分析发现，多肽的结构特征主要表现在氨基酸的残基上，可以用残基的矢量描述子来表征整个多肽的结构，从而使表征过程更为简洁有效。

The coherent inversion method and rootmeansquare velocity conversion method are jointly applied to build the interval velocity model. The tomographic imaging technique is used to optimize the geologic model. Based on the research of depth migration method and comparison of migration effects, the approaches and steps for building accurate migration velocity field are summarized, thus greatly improving the effects and efficiencies of velocity modeling and migration imaging.

采用相干反演法与均方根速度转换法联合建立层速度模型，利用层析成像技术优化地质模型，通过深度偏移方法研究和偏移效果的对比，总结了建立精确偏移速度场的方法和步骤，使速度建模和偏移成像在效果和效率上都得到了很大的改善。

Contrast, metre and seriation are also important for aesthetic feeling and artistic charm in costume design.

另外服装设计的对比、韵律与系列化也是使作品具有美感与魅力的重要条件。
