作者： Yao-Wen Zhang Qing Li Chun-Xiao lv xiu-Jia Liu Xiao-Hui Chen Kai-Shun Bi School of Pharmacy Shenyang Pharmaceutical University Liaoning Institute for Drug Control National and Local United Engineering Laboratory for Key Technology of Chinese Material Medica Quality Control Shenyang Pharmaceutical University

A rapid, simple and practical high-performance liquid chromatography method coupled with diode array detector（HPLC–DAD） was developed to evaluate the quality of Alisma orientale（Sam.） *** a simultaneous determination of four major active triterpenes using a single standard to determine the multi-components（SSDMCs）. Alisol B 23-acetate was selected as the reference compound for calculating the relative response factors. All calibration curves showed good linearity（R240.9998） within test ranges. RSDs for intra- and inter-day of four analytes were less than 3.6% and 2.3%; the overall recovery was 92.1–110.2%（SSDMC）. The proposed method was successfully applied to quantify the four components in 20 samples from different localities in China. Moreover, significant variations were demonstrated in the content of these compounds. In addition, hierarchical clustering analysis（HCA） and principal components analysis（PCA） were performed to differentiate and classify the samples based on the contents of Alisol C 23-acetate, Alisol A, Alisol A 24-acetate and Alisol B 23-acetate. This simple,rapid, low-cost and reliable HPLC–DAD method using SSDMC is suitable for routine quantitative analysis and quality control of A. orientale（Sam.） Juz.

经典的听觉注意计算模型主要针对声音强度、频率、时间等初级听觉特征进行研究,这些特征不能较好地模拟听觉注意指向性,必须寻求更高级的听觉特征来区分不同声音.根据听觉感知机制,本文基于声源方位特征和神经网络提出了一种双通路信息处理的自下而上听觉选择性注意计算模型.模型首先对双耳信号进行预处理和频谱分析;然后,将其分别送入where通路和what通路,其中where通路用于提取方位特征参数,并利用神经网络提取声源的局部方位特征,接着通过局部特征聚合和全局优化法得到方位特征显著图;最后,根据方位特征显著图提取主导方位并作用于what通路,采用时频掩蔽法分离出相应的主导音.仿真结果表明:该模型引入方位特征作为聚类线索,利用多级神经网络自动筛选出值得注意的声音对象,实时提取复杂声学环境中的主导音,较好地模拟了人类听觉的方位分类机制、注意选择机制和注意转移机制.
