A new stock-removing process using a laser beam is proposed.In this process, a laser beam focused into a light strip is used to melt the localized area at the interface bet-ween the material to be removed and the workpiece. The scraps due to melting is removed by a striping tool. The analysis and preliminary experiments proved the feasibility of the method. It has small cutting force and is free from wear and economic in laser energy usage.

提出一种应用激光切削加工的新途径:将激光束会聚成光带,用以加热、熔化余量和零件分界面的微区,周时用工具剥离已分离的切屑,分析和初步试验证明了这种激光切削方法的可行性。其切削力小,刀具磨损小,激光能量使用经济。

Based on the generalized theory of wide electron heam focusing, an aberration theory for wide electron beam focusing with curvilineal optical axis in electrostatic and magnetic imaging systems has ho studied using the rotational and non-orthogonal curvilineal coordinate systems. By defining the integration function, all aberration coefficients of the second-order geometrical aberration, the principal trajectory chromatic aberration and curvilineal paraxial trajectory chromatic aberration are given....

Based on the generalized theory of wide electron heam focusing, an aberration theory for wide electron beam focusing with curvilineal optical axis in electrostatic and magnetic imaging systems has ho studied using the rotational and non-orthogonal curvilineal coordinate systems. By defining the integration function, all aberration coefficients of the second-order geometrical aberration, the principal trajectory chromatic aberration and curvilineal paraxial trajectory chromatic aberration are given. The results of this paper have ho shown to be convenient for analysis and computer processing.

在宽电子束聚焦理论基础上,利用非正交旋转曲轴坐标系,研究了电磁聚焦成象系统的曲轴象差理论.采用象差积分函数形式,导出了二级几何象差、主轨迹色球差和曲近轴色球差的象差系数,使结果适宜计算机处理.本文结果已用于实际电磁聚焦成象系统的设计计算.

Analytic expressions for axial intensity distributions of a Bessel-Gauss beam focused by an aperture lens have been derived by using Coffins diffraction integral, and discussed by numerical calculations. As a limting case, the axial intensity distributions of a Bessel beam focused by an aperturelens have also been studied both theoretically and experimentally.
