对雅典奥运会中国男子篮球队赛中防守能力的分析

用数理统计结合比赛录像分析的方法,对雅典奥运会男子篮球赛中国队防守的情况进行分析。从对方的得分、失误、被抢断、被封盖、助攻、以及篮板球等指标分析,结果显示:与世界强队相比,中国队在防守的攻击性(抢断、封盖、犯规)和干扰性(对方失误、得分、助攻)方面存在较大差距;篮板球技术指标差距不明显。

特殊防卫权若干问题探析

特殊防卫权是正当防卫权的一种特殊形式，两者之间具有包容关系。特殊防卫权除具有正当防卫权应有的基本特点外，还有其独具的特点。通过对特殊防卫权若干问题的研究，可以确定实行特殊防卫权的范围，对于确保公民防卫权的正确实施并防止防卫权的滥用具有重要意义。

Mechanism and Defense on Malicious Code

With the explosive growth of network applications, the threat of the malicious code against network security becomes increasingly serious. In this paper we explore the mechanism of the malicious code by giving an attack model of the maliciouscode, and discuss the critical techniques of implementation and prevention against the malicious code. The remaining problems and emerging trends in this area are also addressed in the paper.     

Evolutionary and ecological implications of cardenolide sequestration in the monarch butterfly

Summary Monarch butterflies sequester cardenolides from their larval host plants in the milkweed genusAsclepias for use in defense against predation. Of 108Asclepias species in North America, monarchs are known to feed as larvae on 27. Research on 11 of these has shown that monarchs sequester cardenolides most effectively, to an asymptote of approximately 350 g/0.1 g dry butterfly, from plants with intermediate cardenolide contents rather than from those with very high or very low cardenolide contents. SinceAsclepias host plant species are distributed widely in space and time across the continent, monarchs exploit them by migration between breeding and overwintering areas. After overwintering in central Mexico, spring migrants east of the Rocky Mountains exploit three predominantAsclepias species in the southern USA that have moderately high cardenolide contents. Monarchs sequester cardenolides very effectively from these species. First generation butterflies are thus well protected against predators and continue the migration north. Across the northern USA and southern Canada most summer breeding occurs on a fourthAsclepias species and in autumn most of these monarchs migrate back to Mexican overwintering sites. The ecological implications of this cycle of cardenolide sequestration for the evolution of monarch migration are discussed.     

空地导弹落点精度评估系统

为满足导弹设计与试验中高精度的落点精度评估要求,以落点精度评估系统为研究对象,从系统的总体设计思路出发,设计并开发了系统的数据库、数据处理子系统以及评估子系统,同时,详细给出了各模块的具体计算步骤及计算模型。最后通过软件的实例计算测试了系统的稳定性和维护性。该系统的设计开发可为装备定型、部队作战使用、研制单位验证设计思想和检验生产工艺提供技术支撑。     

采用HK模型的防空反导作战网络建模分析

采用HK网络模型对防空反导作战网络进行建模,对网络度分布、集群系数、平均距离的统计特性进行分析。将网络模型与典型树状结构的防空反导网络和基于BA无标度模型的网络进行比较,表明基于HK模型的防空反导作战网络具有较好的集群系数和无标度特性,同时表明改变TF连接概率进行防空反导网络设计具有更好的灵活性。
