If you want to include a return address on the envelopes, you can set this up before you start working on the envelope main document. 如果希望在信封上包含寄信人地址,可以在开始处理信封主文档之前完成此设置。
If you need to stop working on a mail merge, you can save the envelope main document and resume the merge later. 如果您需要停止使用邮件合并,可以先保存信封主文档,然后在以后恢复合并。
This paper introduces the working method to render three axes envelope curve of clipping line of geotechnical test using AutoCAD, and explains the windows and menu operations, parameter setting combined with the engineering practice. 介绍了利用AutoCAD2000绘制土工试验三轴剪切线包络线图的作业方法,并结合工程实例对作业过程中的窗口和菜单操作及参数设置等作了具体说明。
The working principle of this system is that an image of grinding wheel envelope profile shot by CCD camera is transported into the computer, then the image is treated by Matlab, finally the geometrical parameters of the grinding wheel envelope profile is outputted. 该系统的工作原理是采用高精度的CCD相机摄取样板上的砂轮包络廓形图像,并将其传入计算机,计算机通过应用软件Matlab对图像进行处理,最终输出砂轮包络廓形的几何参数。
I get the working space of parallel mechanism by surface envelope principle. 通过曲面包络原理求得并联机构的工作空间。
