According to this mode, latitudinal gravity always pushes the earth's matter toward the region of"latitudinal densityanomaly low"from"latitudinal densityanomaly high".
按照这一模式,纬向重力总是把地球物质从“纬向密度异常高”的地区推向“纬向密度异常低”的地区。

According to spherical harmonic coefficients of 360 orders of EGM96 Earth's gravity field model, densityanomaly and tectonic stress in different depth of crust have been calculated.
利用360阶的EGM96地球重力场球谐系数计算了不同深度球层的密度异常及不同深度球层的构造应力。

Results show that the thermal effect of plate motion driven mantle flow and its contribution to the observed heat flow is greater than that due to internal densityanomaly (tomography based).
