好孤立的

To understand the hyperbolic motion of the probe and give necessary orbit information not only the discrete positions to both ground-base or satellite autonomy device, we studied the variation of hyperbolic orbit and gave the variation equations like that of elliptic orbit.

这段轨道相比其它段虽然很短，但却是实现最终探测目标的关键弧段。为了更好地了解探测器的在这一关键弧段的运行状态，给地面测控系统或是星上自主设备提供必要的轨道信息，而不仅仅是探测器在一些孤立点上的位置和速度，有必要对双曲线轨道及其变化特征进行研究，给出类似于椭圆轨道及其变化的一些基本规律。

What's more, we also study some key techniques and realization difficulties of image authentication in-depth, including referent block to help tamper localizing, sign bit adjustment for binary encoding, mean quantization improvement, diagonally extension to help tamper localizing, and discard isolated error point to tolerate incidental distortion. These techniques can be used for good reference to the development of image authentication technique.

此外，我们还对数字图像鉴别的一些关键技术和实现难点进行了深入研究，主要包括有：参考点辅助定位技术、二值编码中的符号处理技术、均值量化方法的改进技术、对角扩展和去除孤立点技术等，这些技术的研究都对数字图像鉴别技术的发展具有很好的借鉴意义。

The method includes the following steps: firstly, a spherical neighborhood of present sample points is established by using the geometric spherical-modelling theory and all the sample points contained in the spherical neighborhood are adopted as candidate neighbor points, thus not only preserving the effectivity of the dimension reduction capability when data sets are sparse but also getting the advantages of low-sensitivity to isolated points and good stability of the preserved topological structure; then a data relevance matrix more matching semantics can be obtained by relevance measurement based on route clusters to update the candidate neighbor points in the spherical neighborhood and optimize the regular neighborhood space of the present sample points, thus improving the phenomenon that the dimension reduction of sample sets provided with folded curved faces is apt to suffer the integrated-structure distortion in case of heterogeneous data distribution.

首先利用几何开球原理建立当前样本点的球状邻域，将包含在球状邻域内的所有样本点作为候选近邻点，不但能够保持在数据集稀疏情况下的降维性能的有效性，而且具有对孤立点敏感性不高、保留拓扑结构稳定性好的优点。然后利用基于路径聚类的相关性度量得到更符合语义的数据相关性矩阵，用来对球状邻域内的候选近邻点进行更新，优化当前样本点的规则邻域空间，改善了当数据不均匀分布时在带有折叠弯曲面的样本集上降维容易出现整体结构扭曲的现象。

5Th,it was reported by ..that American research center's investigation showed that Obama wanted American to sell his new strategy in Afghanistan which was facing arduous tash under the surrounding which isolated feeling was increasing.49% citizen agreed America should'do not have a hand in something in the world' and let other coutries do their own things,however,44% citizen did not agree.

据法新社5日报道，美国佩尤研究中心的一项民意调查表明，在国内孤立主义情绪剧增的情况下，美国总统奥巴马要想美国公众兜售他的阿富汗新战略讲面临艰巨的任务。有49%的受调查民众同意美国&在国际上不应多管闲事&而让其他国家管好他们自己的事，44%的民众则不同意这个观点。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。
