Based on References [1] and [2], this paper has further improved data-processing and transform methods for curved surface potential field of trigonometric funtion, put forward three basic types of curved surface potential processing and transform (pure potential field type, gravity field type and magnetic field type) as well as four important technical measures (plane rotation technique of coordinate, normalization processing technique, translation technique of Z coordinate and block processing technique), compiled corresponding softwares and, through tentative calculation of theoretical model and processing of factual data, tested the correctness of the methods and the effectiveness of the related techniques and measures. Softwares of this suite of methods are charaterized by high adaptability, rapid calculation and high precision.
