摘要：44 plots were set up in different slash pine plantations in Jiangxi *** relationship between the mean population density of Hylobitelus xiaoi and the mean worm hole in slash pine were investigated and 5 functions were found *** results showed that the best suitable mathematics model could be described as: Y=0.082x2+0.2 216x+0.063,and the table of relationship between the mean population density of *** and the mean worm hole in slash pine were established,which provided a simply method for number investigation and forecast of *** in slash pine plantations.

摘要：介绍了目前大型并行计算机系统中互连网络的分类,对其中叫直接网络的一类网络的几种类型进行了分析,讨论了直接网络中路由的相关问题,并针对单向3D torus网络设计了一个点到点的无阻塞的虫孔路由算法。

摘要：六角形蜂窝网格是一种具有良好网络拓扑性质的并行多处理机互连网络.蜂窝网格在某些特性上优于二维网格.不过,这种网络不存在单信道最短路径无死锁路由算法.文中针对该网络设计了两个部分自适应无死锁虫孔路由算法.一个是基于转弯模型单信道非最短路径路由算法,另一个则是采用了虚拟双信道的最短路径路由算法.对第二个算法,还进一步使用转弯模型对其改进.通过仿真实验,结果显示这两个路由算法都具有较好的性能.
