灾害避难行为的模拟模型研究（I）——基本模型的建立与计算机实现

灾害避难行为的研究,不仅直接有助于建筑物内部构造的设计、物件的布局、避难诱导装置的设计,而且也是加强市民减灾意识培养的基础,考虑到灾害实验的危险性和避难行为的不可重复性,建立计算机模拟模型来探求避难行为的规律,已成为对其进行研究的最佳途径,本文重点介绍了避难行为模拟模型建立的原则,模型的构成,基本假设,并给出了计算机袂现的途径,为进一步为实例研究创造条件。     

玉米种子的DNA指纹计算机化鉴定

对１２个优良玉米自效系的ＤＮＡ进行了ＲＡＰＤ分析,共筛选了２５０个Ｏｐｅｒｏｎ引物,其中１２个引物共扩增出５９个多态性产物,根据这５９个多态性ＲＡＰＤ产物,对１２个自交系进行了聚类分析,把它们分为３个群,结果与根据系谱法的聚类结果一致。经过优选,用ＯＰＮ－１１扩增出的１１种ＤＮＡ带,建立了这１２个自交系的ＲＡＰＤ－ＤＮＡ指纹图谱。在该图谱呼弱个自交系都具有特异的ＤＮＡ指纹,可以与其它自效纱相区别。     

Application of Tradable Emission Permits in Europe

The purpose of this study is merely to review the current situation in the designing and implementation of the emission trading programs in Europe. Historical data show that although there is a series of shortcomings in their current functioning, employing such instruments for GHG reduction policy making is strongly expected to be efficient and effective. The European Union Emission Trading Scheme （EU ETS）, Clean Development Mechanism （CDM） and Joint Implementation （JI） are just a few examples of the ambitious EU initiative that heavily relies on such instruments. We dwell on their operations and achievements by far and all the content in this article is expected to convince the Chinese government and regional public authorities to take positive actions and attitudes in promoting these instruments.     

Environmental Impact Assessment and Environmental Audit in Large-Scale Public Infrastructure Construction: The Case of the Qinghai–Tibet Railway

Large-scale public infrastructure projects have featured in China’s modernization course since the early 1980s. During the early stages of China’s rapid economic development, public attention focused on the economic and social impact of high-profile construction projects. In recent years, however, we have seen a shift in public concern toward the environmental and ecological effects of such projects, and today governments are required to provide valid environmental impact assessments prior to allowing large-scale construction. The official requirement for the monitoring of environmental conditions has led to an increased number of debates in recent years regarding the effectiveness of Environmental Impact Assessments (EIAs) and Governmental Environmental Audits (GEAs) as environmental safeguards in instances of large-scale construction. Although EIA and GEA are conducted by different institutions and have different goals and enforcement potential, these two practices can be closely related in terms of methodology. This article cites the construction of the Qinghai–Tibet Railway as an instance in which EIA and GEA offer complementary approaches to environmental impact management. This study concludes that the GEA approach can serve as an effective follow-up to the EIA and establishes that the EIA lays a base for conducting future GEAs. The relationship that emerges through a study of the Railway’s construction calls for more deliberate institutional arrangements and cooperation if the two practices are to be used in concert to optimal effect.

改进“自然景观旅游区环境监测方案”的思考——以武陵源景区为例

旅游区环境监测是获取环境质量信息,进行有效环境管理的基础性工作.由于游客对自然景观区环境要求的特殊性和景区污染排放方式的独特性,自然景观旅游区的环境监测方案设计也应区别于其他区域.以世界自然遗产武陵源风景区为例,运用资料收集、实地调查、访谈等方法对其环境监测方案进行调查,按照旅游环境管理要求对其分析评价,发现存在的问题.在此基础上,提出自然景观区环境监测方案的改进思路,使其更符合自然景观区的环境特点与管理要求.     

A Radio Communication System for Neuronal Signals

To collect neuronal activity data from awake,freely behaving animals,we developed miniature telemetry recording system.The integrated system consists of four major components:1) Microelectrodes and micro-driver assembly,2) analog front end(AFE),3) programmable system on chip(PSoC),and 4) radio transceiver and the LabVIEW were used as a platform for the graphic user interface.The result showed the system was able to record and analyze neuronal recordings in freely moving animals and lasted continuously for a time period of a week or more.This is very useful for the study of the interdisciplinary research of neuroscience and information engineering techniques.The circuits and architecture of the devices can be adapted for neurobiology and research with other small animals.
