The author defines the lshikawa iteration process with errors for a sequence nonlinear generalized quasi contractive mapping in convex metric space s and prove that the iterative scheme converges to the unique common fixed point of the sequence of nonlinear generalized quasi contractive mapping.

在凸度量空间内，对非线性广义拟压缩映射序列定义了带误差的 lshikawa迭代序列，证明了带误差的 lshikawa迭代序列收敛于非线性广义拟压缩映射序列的唯一公共不动点。

Isomap is one of the representative techniques of nonlinear dimensionality reduction.It extends classical multidimensional scaling by considering approximate geodesic distance. However,Isomap is sensitive to noise because the approximate geodesic distance is constructed on the basis of Euclidean distance. In this paper,a kernel-induced distance metric defined in the feature space is introduced instead of the Euclidean distance to evaluate the geodesic distance and construct the corresponding neighborhood graph.

采用核方法在特征空间推导出一类异于欧氏距离的新度量，代替等度规特征映射中的对噪声敏感的欧式距离，用新度量构造测地距离和相应的最小近邻图，提高Isomap算法的抗噪声能力。

These two poets can be said to represent the birth of two major American poetic idioms-the free metric and direct emotional expression of Whitman, and the gnomic obscurity and irony of Dickinson-both of which would profoundly stamp the American poetry of the 20th century.

The solution is to play a soft, unobtrusive grace note on the beat and a main note with its metric value intact.

解决的办法是在一拍里弹奏一个柔和的、不突出的装饰音而且必须确保主音的音值长度的完整。

The fact that it extends the metric value of the bass is no cause for alarm; this effect may be exactly what the composer intended and the reason he uses the grace note.

事实上，延长了低音的音长并没有引起恐慌；这些音乐效果证明，作曲家的意图和运用倚音的理由是正确的。

We must never deduct the metric value of the grace note from that of the main note and shorten it; instead we should add the value of the grace note to the value of the beat.

我们决不从主音中扣除倚音，而且也不将其缩短；相反，我们还要增加倚音拍长的时值。
