The proposed method can detect certain object boundaries, for which the original method is not applicable. E.g. it can automatically detect interior and exterior contours of an object and edges of multi-objects, starting with only one initial curve whose position is anywhere in the image. Moreover, active contours can move into boundary concavities and perform better in the presence of weak boundaries.

它能够解决原方法所不能解决的一些图像分割问题，例如，能够从任意选取的一条初始曲线出发自动检测目标物体的内外轮廓，检测多目标物体以及深度凹陷区域的边缘，并能较好地提取目标物体的弱边界。

However, along with the use in a deep going way, most users find that the forest reserves map which is built by traditional vector data models in GIS is different from the real.:In traditional forest distribution map, we give tacit consent to the fact that the forest is represented by a polygon, whose boundary is taken as a abrupt change between different types and the interior of the polygon is regarded as uniform.

随着应用的深入，很多用户发现通过传统GIS的矢量模型模式构建的森林资源图上所表示的信息与客观世界中森林的分布是有差别的：基于传统的GIS矢量模型下构建的森林分布图中，多边形的边界默认为一种突变，同时森林内部被认为是均匀的。

对于传统的运输问题，应用线性规划内点算法的基本理论，结合运输问题模型的特殊性，提出了运输问题内点算法的基本理论和一般步骤。

Around this one problem, deng Xiaoping replied to want to cast off poverty to be able to take what road, practical approach only theoretically, how key of deploy, job and how to handle correctly interior and external the problem such as the relation.

围绕这一问题，邓小平理论回答了要摆脱贫困只能走什么道路、现实途径、怎样部署、工作重点以及如何正确处理内部与外部的关系等问题。

The full space calculation model, which suits for the asymmetric structure sometimes even including air below the surface of medium, can enable simulative result to approach real one. The FDTD algorithm based on the mixed ABCs is proper to calculate the transmission line where the electromagnetic wave is transmitted in order to send electromagnetic energy along central conductor. The calculation efficiency will be raised if the PML absorbing boundary condition is set on both planes of transmitting direction and so is the MUR two-order absorbing boundary condition in the other planes.

全空间计算模型是适合所有的不对称结构的待研究体的，而且包括了介质下面的空气部分，使仿真更加的接近实验真实情况；基于MUR-PML混合吸收边界条件的时域有限差分法非常适合计算传输线这种结构，因为传输线是传送电磁波的，电磁能量主要是沿着中心导带行进，因此在两个传输端面上设置PML完全匹配层吸收边界条件，在其他面上设置MUR二阶吸收边界条件，会大大提高计算效率，而且计算结果与XFDTD仿真软件计算结果相比较，基本趋于一致。

In the third part, we discuss a simple class of Sturm-Liouville problems with Dirichlet boundary condition in the first boundary condition and an affine function in the second one.

第三部分我们讨论了一类参数边界条件的Sturm-Liouville问题，其第一边界条件为Dirichlet条件，第二个边界条件为特征值参数的线性函数。

A stress function involving several unknown co efficients was constructed in the solution process, and the stress and displacement expressions were obtained through traditional Airy stress function methodology. After the fixed end boundary condition was treated with two methods, the unknown coefficients in stress function were determined with stress and displacement boundary conditions, and the analytical solutions were achieved.

在求解过程中，构造了一个含待定系数的应力函数，通过Airy应力函数解法，给出了应力和位移的表达式，对固支端边界条件采用两种处理办法，利用应力和位移边界条件，确定应力函数中的待定系数，得到了应力和位移的解析解结果。
