The main purpose of this article is to work over and analyse dynamic specialties of the plane four bar mechanism especially crank and rocker mechanism and brace cake mechanism in the dynamic and constrained system contained with mechanical and hydraulic integration, and dynamic specialties of the plane four bar mechanism in the system made of mechanical and hydraulic integration can carry out and be easily computed by the software MATLAB to have a simulation.

本文的主要目的是研究分析机械系统和液压系统综合动态约束系统下，对机械系统单元部分选取的平面四连杆机构，尤其是曲柄摇杆机构和曲柄滑块机构的动态特性，并能通过MATLAB软件实现对机液综合机构学理论中的平面四杆机构的动态特性计算及仿真研究。

Herbivore species are highly constrained in the range of plant tissue they can eat, due to plant defences, and hence may be level, plants are not energy-limited but space limited, so any space cleared by herbivory opens opportunities for more plants.

由于植物有防御，食草物种在它们所吃的植物组织的范围方面是受到很大限制的；因此，即使世界是绿色的，它们也可能受到竞争的限制。不仅如此，植物大体上并不受能量的限制，但却受到空间限制，所以任何被食草动物清出的空间，都为更多的植物开放的机会。

Are highly constrained in the range of plant tissue they can eat, due to plant defences, and hence may be level, plants are not energy-limited but space limited, so any space cleared by herbivory opens opportunities for more plants.

不仅如此，植物大体上并不受能量的限制，但却受到空间限制，所以任何被食草动物清出的空间，都为更多的植物开放的机会。

This paper takes the advantages of FPGA"s regular routing resources to judge the crucialities of each net to be routed, aims at determining the routing order,which greatly helps to improve the routability based on area-constrained and reduce time cost at the same time. When taking nets" high demand for delay into account, this paper takes full use of mid-length segments.This paper builds an NCJ algorithm routing model, then showes a router consists of NCJ global router and SEGA detailed router which is implemented by C++ program language.

本文充分利用FPGA芯片本身具有的固定的规则的布线资源这一特点，提出在对每一个线网布线之前将待布的线网进行关键性分析，再根据关键性大小对关键性相对大的线网进行布线，即NCJ算法；此算法有效地在保证芯片性能的同时，提高了布线资源的利用率，同时考虑到深亚微米时布线时延是影响芯片性能的一个重要因素，因此充分利用芯片的中长线布线资源以减少通过编程开关的几率。
