Hence, reproducing kernel function has not only the advantage of calculation, e.g.it can transform the integration into the sum of finite function values, but also theadvantage of local characteristic of wavelet function.

所以再生核函数既具有计算优势，如能将积分计算准确地转换成有限个函数值的和来计算，又具有小波函数的局部刻画优势。

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.

Results:Whith the time and doses of ART incubation extended, ART significantly inhibited the proliferation of SGC-7901 cells and the inhibited effect shows dose-and -time-dependent. Obvious changes of apoptotic morphology were observed by invert microscope, fluorescence microscope, scanning electron microscope and transmission electron microscope, they showed that cells had marked nuclear condensation or the fragmentation of chromation as well as apoptotic , mitochondrial edema and vesicle , with the time of incubation extended , the proliferation rate become slow and the volume became small and transformed. FCM assay indicated that most of the cells were arrested in Go/Gi and the apoptotic peak appeared. During the prolong of incubation time, the apoptosis rate was increased. At the same time, the number of S and G2/M phase cells were decreased. The result of TUNEL indicant that there are apoptosis and necrosis.
