1·An axial symmetrical model is set up for the sealing structure of the bulkhead plate for a columniform dewar.

建立了针对柱形真空杜瓦容器端盖密封结构的轴对称模型。

2·It can label front and back stickers on the columniform containers at the same time , and the label distance can be adjusted optionally;

圆周卷贴，可实现正、背两张标签的同时粘贴，且两张标签间距可随意调整；

3·Top is columniform structure, and bottom is coniform structure. With covering small area and storing large capacity of lead oxide, it can realize lead oxide first in and out.

粉仓上部为圆柱形下部为圆锥形结构，储粉量大、占地面积小，能实现铅粉先进先出。

4·This paper analyses the coupling wastage in columniform wave guide gas laser, and gives the function between the coupling wastage of laser guide modulo EH11 and the position and radius of reflector.

分析了圆柱形波导气体激光器中的耦合损耗，给出了最低阶波导模EH11的耦合损耗与反射镜位置、曲率半径的函数关系。
