Once the program is loaded, only a few parameters are given, the development drawings of variable pitchhelical blade will be obtained.
该程序一经调用,只要给出几个相关的参数,即可绘出变螺距螺旋面展开图。
2
The new tooth surface can be prolonged by the normal profile of the internal toroidal surface, or replaced by an equal pitchhelical surface.
其二为一种修整的线接触,展成的等螺距齿面与理论轨迹曲面沿某一空间曲线近似相切。
3
The two helical nanofibers have absolutely opposite helical senses, but have identical cycle number, coil diameter, coil length, coil pitch, fiber diameter, and fiber cross section.
