Firstly, we normalized the basic voxel by constructing its minimum oriented bounding box. Secondly, we constructed its D2 shape distribution curve, and computed the values of EMD(earth mover's distance) compared with the corresponding curves of the normal cone and cylinder respectively, and the corresponding top diameters. Finally, we compared the top diameters and obtained the parameters by the bounding box.

首先建立基本体素的MOBB，对体素进行标准化；然后生成其D2形状分布曲线，计算此曲线分别与标准圆锥体形状分布曲线、标准圆柱体形状分布曲线的EMD(earth mover's distance)值以及相应的上底直径；最后通过比较两个上底直径的大小来判断此体素是否为圆台体，并由包围盒的边长给出圆台体的参数。

Phenomena such as precession the slow roughly 25 000 year cycle of movement of the direction of the Earth's axis and nutation the continual "nodding" of the Earth's axis due mainly to tidal forces from the Sun and Moon all have to be taken into account when defining a Universal Reference frame.

The orientation of the projection surface can be normal (inline with the earth's axis), transverse (at right angles to the earth's axis) or oblique.

常见的投影方位有正轴、横轴、斜轴。

In brief, may say that, the planetoid and Earth's rise and fall is closely linked, therefore studies in solar system's planetoid to say to our group or is all has the extremely important research significance to the Earth.

总之，可以说，小行星和地球的兴亡息息相关，因此研究太阳系内的小行星对我们小组来讲或者是对地球都是具有十分重要的研究意义的。

It mainly contains the seismic velocity structure of the earth's interior, anisotropy of the mantle, mantle discontinuities and the physical properties of mantle. It can be found that new progress in the study on the structure and physical properties of earth's interior has been made in the recent years in China: In some preexistent areas much progress has been made, advanced methods have been adopted, extensive international co-operation has been conducted in many ways, the scope of the co-operation has gradually expanded, and some new fields appear as well.

从地球内部结构的地震波速度成像，地幔介质的各向异性，地幔间断面及地幔介质物性进行了综述，指出在一些原有的研究领域，工作更加深入，方法更加先进，而且进行了广泛的国际合作，合作的范围也逐渐扩大，方式多样，并开拓了一些新的研究方向。

The computation of sky radiance resulted from the earth's diffuse reflection is studied based on a hypothesis that a underlying surface is randomly rough. The paper gives an analysis of the method to calculate the reflectivity, average hemisphere reflectivity, and transmission in virtue of the reciprocity law from the earth's surface to the top of the atmosphere.

This paper has investigated the expression on rotational motion of earth's surface and Earth's deformation fields with complex vector surface spherical harmonic function, theoretical definition of the crust-fixed reference frames and the terrestrial reference system, and theoretical substantiating to the consistency between them.

徐州师范大学国土信息与测绘工程系，徐州 221116；2。中国科学院测量与地球物理研究所，武汉 430077摘要：本文研究了内核地球模型下的地球表面的旋转运动和地球形变场的复数矢量球函数表示，以及外壳固定参考架、地球参考系的理论定义和它们之间等价性的理论证明。

The more strict equations of the GPS static absolute position are obtained,by considering the effect of the transmission of signal in earth's gravitation,on the condition that the earth's gravitation is static and spherically symmetric.

笔者认为导航卫星在地球周围的引力场中运行，因此要作精确的定位就必须考虑时空的弯曲结构对信号传播的影响，进而对GPS系统的静态绝对定位方程做出修正。1 GPS静态绝对定位原理如图1所示。
