Moreover, the radius of attraction of memorized sample patterns is presented. A Hybrid neural network model for pattern recognition is presented. The model consists of a cascade connection of three neural networks, which are hetero—associative NN、2—D local—connected NN and classification NN respectively.

When based on dual wavelength chromatographic data analysis, a new method, namely dual wavelength characteristic information analysis, used for the base line correction, determination of number of components and region of pure components signal.

但色谱峰的重叠给多组分的同时分析带来了困难，因此针对色谱重叠峰的解析提出了不少方法，如曲线拟合、神经网络、小波变换、窗口因子分析、直观推导式演进特征投影分析等 [1～ 7] 。

Results Fibronectin existed in dental pulp and predentin, and also in space between the wall of dentinal tubule and process of odontoblast in mature dentin. They were mostly distributed in odontoblast layer and round blood vessels and nerves. In the crown pulp, integral optical density, length density and volume density were 0.49±0.33,38.44±20.7 and 24.56±10.8 respectively.

We postulate that the "ridged band", with its unique structure, tactile corpuscles and other nerves, is primarily sensory tissue and that it cooperates with other components of the prepuce.

我们认为，Ridged Band是一个特殊的结构，包含了触觉小体以及其他神经，是包皮上的主要敏感组织而且它和包皮的哦其他部分协作。

The number of window-like holes and dells of neuron cell membrane induced by salvianolic acid B increased obviously, this appearance may be relevant to strengthening the effect of substance exchange between exterior and interior cell, and promoting the signal transduction of intra-cellular.

丹酚酸B诱导神经干细胞分化的神经元细胞膜的窗孔样结构与小凹明显增多，可能与增强细胞内外物质交换功能和促进细胞内信号转导有关。

The algorithm is designed to work directly on the wavelet compressed domain which possesses the following characters: First of all, the multi-level gradient energy presentation of face pattern is proposed, which not only can highlight the facial parts in possible face patterns, but also can address effectively the problem of unknown size in face detection in compressed domain and therefore avoid the complex resolution transform in arbitrary ratios ; secondly, the skin-color model in YCbCr space is ameliorated to improve the reliability of skin segmentation; finally, a hierarchical detector which integrates the simply rule-based classifiers and complex neural network based classifier is designed to further improve the processing speed.
