摘      要：This paper presents a direct gravity inverse method of multilayered variable density models, and gives gravity forward formulae under various conditions of density-depth functions such as the constant, exponential, linear, sine and cosine, cubic spline, and Fourier progression. The testing of theoretical models and the analysis of real examples have been made for the cubic spline function and have proved that the method is effective. Other formulae can be applied under corresponding conditions by means of optimization or other methods.
