We studied the short-term changes to the carbon cycle in a mixed stand of hemlock and hardwoods, where hemlock was declining due to either girdling or HWA infestation.

我们学习了短期的变化对碳循环的混合物，叶、硬木叶围绕由于要么是下降还是华出没。

One by one the soldiers around him stumbled back, turning to run sobbing or praying down the hill, lurching into the darkness of the girdling trees.

围绕在他四周的卫兵们，一个接一个地踉跄后退，转身跑开，有人哭泣着跑下山，有人祈祷着跑下山，有人冲进周围黑暗的树丛里。

The production of globoid indexing cam and gas engine burningchamber are employed as refrences to analyze the method to mathematical modeling of complexed functional feature, furthermore, the research work of the character of surface feature production is deeply done .Advancing and optimizing the producting process, as well as the whole simulated machining by making UG NX2. 0 as the supporting system. Building the Fixture Library CAD/CAM Document system and producting template of DMU70V. Exploring the structure and flow chart of the Document System;Developing the MDF File by means of GPM module. All the above provide profound preparation to establish a further integrated manufacturing environment around 5-Axis NC production center.

在本文中，综合论述了特征建模的方法，以弧面分度凸轮和内燃机燃烧室作为实例，重点研究了复杂功能曲面的建模及曲面分析方法；并从五坐标加工角度出发，详细研究了曲面零件的加工特性，提出并优化了具体的工艺过程；利用UnigraohicsNX2.0作为开发工具，对建模和加工过程进行了全程仿真；围绕DMU70V建立了专属夹具库、文件体系及工艺模板；综合规划了五坐标数控加工的CAD/CAM文件体系的结构和运作流程；开发了GPM五坐标后处理DMF文件，为建立以五坐标数控加工中心为主的加工体系打下了良好的基础。

This thesis discusses CAD for globular indexing cam mechanism on base of reverse engineering.

本文是围绕弧面分度凸轮机构CAD中的逆向设计进行的。
