Statecharts for Distributed Product Data Management System Modelling

Product data management (PDM) has been accepted as an important tool for the manufacturing industries. In recent years, more and mor e researches have been conducted in the development of PDM. Their research area s include system design, integration of object-oriented technology, data distri bution, collaborative and distributed manufacturing working environment, secur ity, and web-based integration. However, there are limitations on their rese arches. In particular, they cannot cater for PDM in dis...     

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.     

汉人王弥与匈奴汉国的地方统治

公元307年,王弥反晋起义失败后,决心依附匈奴汉国。他和刘渊“深有分契”,尽量利用汉国的名义,其势力逐渐达到“东王青州”的程度。他成为匈奴汉国地方武装势力后,始终以半独立的状态存在。将以王弥为例,寻找汉国地方武装势力的生存过程,并分析其地方统治模式是一件颇为有意义的工作。

从科学史观点试谈奇门遁甲（续完）：1997—10—03在西北大学的讲演

就最早出现在东晋葛洪的《抱朴子内篇》的遁甲和８世纪最早的有关奇门遁甲的文献记载进行讨论。述及北宋司天台采用奇门遁甲,下至有明一代奇门遁甲成为官方采用三式中的一种秘传术数的过程。示范奇门遁甲的布局方法,并举例解释它在气象学、军事和人事各方面的应用。认为传统中国从来没有科学这个名词,欧洲在文艺复兴时代以前也没有这个名词,可是认识和克服大自然这个理念应该早已存在,这就是所谓科学的前身。又认为奇门遁甲是传统中国理念中的科学,后来在欧洲科学与巫术、哲学、宗教等分手,可是奇门遁甲没有脱离它和人事、巫术等的关系。     

Effect of 723-1723-1723-1on ethanol withdrawal in mice

Summary ⁹ (10 mg/kg, i.p.) administered to mice immediately after withdrawal from a 3-day exposure to ethanol vapor was found to intensify withdrawal reactions. No effect was seen when ⁹ was administered chronically during the exposure to ethanol.     

北宋明州高丽使行馆

明州(即宁波)地处中国大陆东海之滨，航道四通八达，海外交通便利，是开展海外贸易较早的城市之一，和世界各国进行通商贸易已有一、二千年的历史．到了宋代，明州和世界各国(如：高丽、东南亚、阿拉伯等)的交往达到繁盛的阶段．特别是到了北宋时期，明州与高丽的交往有了显著的增加．北宋时，由于与高丽的交往日益频繁，高丽来明州的人日益增加，北宋政府为了接待高丽使者和商人，在明州兴建了“高丽使行馆”．为了了解北宋和高丽的交往情况，中韩两国历史学界和建筑学界提供了许多重要的线索，高丽使行馆作为两国交往的重要场所有很高的研究价值．本文尝试了解、研究有关高丽使行馆的情况．     

近红外光谱技术鉴别海面溢油

近红外光谱技术分析速度快、效率高、成本低、重现性好,典型的无损分析;主要用于样品类别鉴定和纯度检验.近红外光谱技术结合模式识别方法,在纯品油种类的鉴别中已得到成功应用[1,2],本实验室也初步建立了纯品油近红外谱图数据库[3],但该法在实际海面溢油样品的鉴别中应用仍甚少.     

电缆在圆护管内的散热研究

本文的研究是为了系统地了解不同直径、长度和材质的圆护管对电力电缆散热的影响，重点是了解圆护管与电缆间空气夹层中的散热情况，对电缆在圆护管内的散热进行了实验研究和数值模拟，给出了通常使用的圆护管直径范围内的传热经验公式，护管内径与电缆直径的最佳尺寸比、护管材质影响，电缆导体温升与护管长度的关系。
