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.

在断续切削中，铣削波形可被看作周期函数，将单齿铣削波形看成为脉冲函数，经过傅立叶变换，可以表示为一个按特定的基本频率变动的正弦波形的分量和许多个按基本频率的整数倍而变动的正弦波形的分量叠加而成，讨论所获得的频谱函数，是研究三维复杂槽型铣刀片切削性能的主要环节，以便了解影响单齿铣削波形幅值谱图的各种因素，并从功率谱图的组成情况来考察动态铣削波形的特性，从而进行槽型的设计和优选。

ABSTRACT The ionic strength of mobile phase can significantly affect the peak shape of ionogenic compounds such as antibiotics in reversedphase high performance liquid chromatography. The influence may be attributed to overloading of ionogenic analytes in lower ionic strength mobile phase. In such phase, peak becomes increasingly rightangled triangle in shape with increasing sample load together with increasing peak width and tailing.

在反相高效液相色谱过程中，流动相的离子强度可显著影响可解离的化合物如抗生素的色谱峰形，原因在于流动相的离子强度较低时，色谱填料的固定相易于过载，使离子化的化合物的色谱峰形呈典型的过载特征――峰形接近直角三角形。
