图2 Tesseroid单元体网格剖分示意 a—常规剖分的网格边长大小平均,Lφ和Lλ为Tesseroid单元体上表面纬度和经度方向上边长;b—自适应剖分方案的剖分采用的是在观测点近距离处小网格剖分,远距离处采用大网格剖分

Fig.2 Sketch of discretization of Tesseroid a—routine discretization shown that the tesseroid had a uniform division. Lφ, Lλ are the dimensions of the tesseroid’s top surface;b—adaptive discretization shown that a fine division of the tesseroid close the computation point and a coarser division further away
