研究结果表明，测区沉积物中氟含量分布主要受周围岛屿风化基岩的化学成分制约；沉积物中主要含氟矿物：萤石/磷灰石、黄玉、黑云母等含量极低，氟在沉积物中赋存的矿物相主要与角闪石[AX_2Y_5Z_8O_(22)_2]有关。氟含量与碎屑矿物中角闪石的体积比间的关系式可大致表示为：氟含量=217+361nV_H；间隙水中的低氟主要由测区化学风化不发育及氟的钙盐沉积所致。

New boundary integral equations for the torsion problem of an isotropic bar with curvilinear cracks are derived by using integration by parts and other techniques to the traditional boundary integral formulations. And the boundary integral equations for the torsion problem of an anisotropic bar with curvilinear cracks are also derived by using the isotropicalized boundary element method. Then the anisotropic problem can be solved on the base of the boundary element method of isotropic problem.
