茶树品种分类的探讨

  It is generally accepted that tea plant (Thea sinensis L.) is originated in China, where has numerous varieties,  According to the literature, the selected work of tea plants may be traced as early as to the 3rd-5th century A.D.  The number of varie- ties discovered in recent years reached more than 300.  Besides, a large number of wild species were discovered. In all tea varieties, the crown canopy, leaf size and the date of sprouting were different.  It was proposed that according to the crown canopy, leaf size and the date of sprouting.   The  principle of the classification  of Chinese tea varieties may be 3 orders.  The first order named “group”, it contains macrophanerophyte group, microphanerophyte group, and frutex group.  The second order named “type”, it contains extreme large leaf size, large leaf size, medium leaf size and small leaf size.  The third order named “species”, it contains the early- sprouting species, medium-sprouting species and late-sprouting species.       

实践性知识:教师专业发展的知识基础

教师在从事日常教育教学工作中自身如何发展 ?教师的专业发展具有什么知识基础 ?为什么教师学了教育学、心理学 ,还是不会教书 ?教师如何提高自我专业发展的意识和能力 ?———这些问题是本文探讨的焦点。文章从教师的知识构成入手 ,将教师的知识分成“理论性知识”和“实践性知识” ,然后对教师实践性知识的定义、内容、状态和形成机制进行分析 ,并强调了“教师实践性知识”这一概念的赋权意义和专业建设意义。     

Probability Density Function Method for Observing Reconstructed Attractor Structure

Probability density function (PDF) method is proposed for analysing the structure of the reconstructed attractor in computing the correlation dimensions of RR intervals of ten normal old men. PDF contains important information about the spatial distribution of the phase points in the reconstructed attractor. To the best of our knowledge, it is the first time that the PDF method is put forward for the analysis of the reconstructed attractor structure. Numerical simulations demonstrate that the cardiac systems of healthy old men are about 6 - 6.5 dimensional complex dynamical systems. It is found that PDF is not symmetrically distributed when time delay is small, while PDF satisfies Gaussian distribution when time delay is big enough. A cluster effect mechanism is presented to explain this phenomenon. By studying the shape of PDFs, that the roles played by time delay are more important than embedding dimension in the reconstruction is clearly indicated. Results have demonstrated that the PDF method represents a promising numerical approach for the observation of the reconstructed attractor structure and may provide more information and new diagnostic potential of the analyzed cardiac system.
