两段绞接式联合收割机输送槽的设计研究

本文介绍一种适宜配置在悬挂式联合收割机上的两段铰接式输送槽设计,这种输送槽后段固定,前段与割台连接并与后输送槽铰接,该铰接点为前悬挂割台的支点,借助液压油缸升降,文中对该铰接点位置的确定,以及两段输送槽铰接处的圆弧过渡板设计进行了分析研究,提供了设计方法.

Intelligence service binding architecture for interoperability between home network devices

Existing home devices in home network provides only independent services limited on a homogeneous protocol and/or do not fully support an intelligent service provided by cooperating among heterogeneous protocol devices. This paper proposes an intelligent and integrated service binding architecture which allow the users to figure out the status of devices and to cooperate among home network devices regardless of supported protocols or operational characteristics.

冬虫夏草菌丝体对小鼠体液免疫的影响

本文采用血清溶血素测定新方法,对兰州三爱堂解放军第一医院人工发酵培养的冬虫夏草菌丝体进行实验分析。结果表明,对正常小鼠的体液免疫功能无影响,但对由环磷酰胺引起的体液免疫功能低下有明显的恢复,说明该菌丝体与天然虫草有一致的功能。

初中生学习化学兴趣的发展趋势

针对目前初中化学教学中学生因缺乏应有的学习兴趣而导致学习动力不足和影响其个性和谐发展的问题，运用现代教育学、心理学的理论，结合初中生的心理特点和化学学科特点，提出把初中生学习化学兴趣提到学生稳定的个性心理品质上来研究，是符合马克思主义关于人的学说和现代教育心理学理论以及初中化学教学实际的；初中生学习化学兴趣的形成和发展是一个立体发生的过程，其纵向趋势为：直感兴趣→解析兴趣→探索兴趣；其横向品质为：指向性、持久性、广泛性和有效性，初中生学习化学兴趣水平的提高应当在有效的教学中进行     

Finding global minima with a new dynamical evolutionary algorithm

A new dynamical evolutionary algorithm (DEA) based on the theory of statistical mechanics is presented. This algorithm is very different from the traditional evolutionary algorithm and the two novel features are the unique of selecting strategy and the determination of individuals that are selected to crossover and mutate. We use DEA to solve a lot of global optimization problems that are nonlinear, multimodal and multidimensional and obtain satisfactory results.
