Typical methods of the first class consist of predictive deconvolution, normal moveout interconversion stacking, f-k transformation, tau-p transformation, parabola Radon transformation and beamforming. They can be called as seismography method based on the geometry. The second class methods, mainly bases on elasticity undulatory theory, through simulation or reversal development method forecast multiple, and then match it with the original data.

比较典型的方法有预测反褶积、正常时差变换叠加、f-k变换、τ-p变换、抛物线 Radon 变换和聚束滤波等，它们可以简称为基于几何地震学方法或"几何滤波类方法"；第二类主要是基于弹性波动理论的方法，通过模拟或反演方法来预测原始数据中多次波，继而从原始数据中匹配减去所预测的多次波。

Based on the stress analysis to spired axis mechanism,in the aspect of sliding part which smoothes through alveolus intersection, theresearch of parameters optimization, about the middle alveolus of spired axis andthe dimension of sliding part, has been studied. To the problem that the reverseportion at the both sides of spired axis lashed fiercely and fraies quickly, thearticle finely analyses the best curve of alveolus when adding cushiony spring atthe both sides.

在对螺旋轴机构进行受力分析的基础上，从滑块顺利通过齿槽交叉点的要求方面，对螺旋轴中间段齿槽和滑块的尺寸进行了参数优化分析；针对螺旋轴两端曲线齿槽反向段在高速工作时冲击大、磨损快的问题；从减少滑块在齿槽反向段运动的冲击方面，比较分析了圆弧、抛物线、三角函数等曲线作为螺旋轴齿槽反向段曲线的加速度，提出了较优的(来源：ABCab论bf文网www.abclunwen.com)反向段曲线。

By the detail discussion onthe hardware of the smooth path control system of single-chip microcomputer developed and the system software including new type continuous smooth path software, the analyzing of international standard program languageISO andthe attempt to developmental application in the smooth path control systemand experiment have been done, the description of the smooth path of the non-circular curive such as ellipse, hyperbola, parabola and their realignment has been realized by the way directly to input their parameters. The correctnesson the priciple and the method of the continuous smooth path control and the forthright on programing method hayed been proved by the experiment, new way to realize higher accracy continuous smooth path control has been developed.
