虚拟

Considering minimization of total wire length as the objective, it allows virtual blocks to transform into rectilinear shapes without overlaps and selects the optimum shapes for virtual blocks. It is based on the dead space block assignment and pin allocation during the process of packing.

该算法以线长最小化为目标，通过在位置优化过程中对虚拟模块进行无重叠的直角多边形变形来实现虚拟模块的形状优化，形状优化过程是基于模块填装过程中的空白区分配算法和引脚分配算法，并以降低线网在半周长模式下的线长下限为其主要理论依据。

Based on them, the simulation system of UAV decimeter wave instrument landing system was designed with the support of LabView's abundant graphic functions and powerful mathematics functions.

crime of despoliation ; network suppositional property ; main characteristics ; criminal regulations and system

一、网络虚拟财产抢劫犯罪的主要特征抢劫对象———虚拟财产当前网络游戏、网络聊天等都非常流行，据报道在未来几年内，国内

Suppositional property is of property nature and can be the object of network pillage;network suppositional despoliation is a new form of behavior of such kind of despoliation crimes,and crime subjects have changed rather obviously,along with many legal problems emerging.Based on and to get used to these changes,our country's criminal law concerning striking crimes must be amended and perfected in time thus to regulate despoliation crimes of network suppostitional property of new types.

不可否认，计算机网络在给人们的生活和工作带来了巨大好处的同时，它也改变了许多传统犯罪的表现形式，比如说抢劫犯罪中，抢劫网络虚拟财产，①网络虚拟抢劫，抢劫主体的年轻化、技术化等都是传统抢劫犯罪所未曾有的，本文就以上问题作初步的刑法理论分析，并对这些新问题提出相关的应对措施。
