In the incontinuous cutting, the wave shape of milling can be looked as periodic function. When the milling wave shape with single-tooth was looked as impulse function, by the Fourier Transform, we can find out that it is composed of sine wave with a given frequency and a series of integer multiple frequency. Discussing on the power function is a major tache for studying on the cutting capability of the complex three-dimension groove milling inserts, so to know the facts that affect the single-tooth milling spectral value, and to observe the dynamic milling wave property from the composition of the power spectral, thus we can design and optimize grooves.

The contour map is the easiest to distinguish the height of the terrain. According to the study, it demonstrated that the contour map has to be understudied by learning.But there have not suitable teaching materials to supply learning. However, the conventional map is restricted on the paper; the real world must be displayed by usingthe two-dimension. From this research, using the olography in order to get observe the terrain of stereoscopic vision and analyze the geology.

中文摘要等高线地图是最易判别地形高低的地图，但相关研究中显示等高线图必须经由学习才能看的懂且并无适当的教学媒材及设备供学习，而早期传统的地图受限於纸上，必须将真实的世界以二维的方式来展示，现在如果透过全像立体影像的技术，便可将一般平面影像制作成三维立体影像，以便於做地形的立体观察及地质判释。
