The Grove Mountains expedition is one of the highlights of this expedition, after surveying and mapping personnel have conducted four times the Grove Mountains mapping, geology and glaciology comprehensive survey, field mapping of the Grove Mountains, the surface of the core area of 110 square kilometers topographic maps and maps of protected areas; emplaced 10 geodetic control points, seven ice-flow monitoring stations; the use of different resolution optical images, SAR images, carried out the distribution of the ice fissure information extraction research, production of the Grove Mountains region Flat satellite image maps, digital elevation models and a wide range of blue ice distribution maps, for my recovery to the 9834 Antarctic meteorites have made contributions.

格罗夫山考察是本次考察的亮点之一，此前，测绘人员已进行过4次格罗夫山测绘、地质与冰川学综合考察，实地测绘了格罗夫山核心区110平方千米表面地形图和保护区地图；布设了10个大地测量控制点、7个冰流速监测站；利用不同分辨率光学影像、SAR影像等，进行了冰裂隙分布信息提取研究，制作了格罗夫山地区平面卫星影像图、大范围数字高程模型及蓝冰分布图，为我国回收到9834块南极陨石作出了贡献。

In sphere approximate, GPS/Gravity-BVP is Neumann problem over exterior spherical domains. Then the natural boundary reduction, suggested by Feng and Yu, is applied to deal with the three dimensional problems. By expansion in spherical harmonics, the natural integral equations of harmonic problems over exterior spherical domains are obtained. Meanwhile, a numerical method for solving geodetic BVP is developed.

在球近似下将GPS-边值问题转化为Neumann外问题，用自然边界元法进行自然边界归化，得到自然边界积分方程，再求自然边界积分方程的数值解，与其他边界元方法相比，自然边界元法的计算量大大减小，并且具有很好的逼近性质，能有效地处理奇异积分，是求解GPS-边值问题有效方法。
