  1. 本文以参考椭球面为边界研究变分情形下S-N类混合边值问题的适定性。

    The proper determination of S-N mixed boundary value problem on the reference ellipsoid is studied in this paper .

  2. 并介绍了有关参考椭球面与大地高、大地水准面与正高、似大地水准面与正常高的概念。

    And introduces reference ellipsoid and geodetic height , geoid and orthometric , like the geoid and normal height .

  3. 论文首先从椭球坐标的Laplace方程和常用的椭球谐函数出发,介绍了参考椭球面外调和函数的椭球谐级数展开。

    Firstly , according to the Laplace equation of ellipsoidal coordinates and the ellipsoidal harmonic functions in common use , the ellipsoidal series expansion of harmonic functions outside the referential ellipsoidal is introduced .

  4. 参考椭球面上的水平形变网平差

    Adjustment of horizotal deformation network on the ellipsoid reference information

  5. 本文讨论了水平形变网在参考椭球面上的平差问题,以邢台地震区的水平形变网为例,说明在参考椭球面上作高精度水平形变网平差是可行的。

    In this paper , the adjustment of horizontal deformation network on the ellipsoid is discussed , with an example of the adjustment of deformation network in the region of the Xingtai earthquake ( 1966 ) .

  6. 控制测量在数据处理时,通常要进行两次投影(地面→参考椭球面→高斯投影平面),也相应地产生两次投影变形,不利于大比例尺测图和工程施工放样。

    When processing data in controlling survey , we usually project twice ( land surface → according to ellipsoid plane → gauss projection plane ) and it brings about Deformed projection twice too . It is not good for large scale mapping and setting-out of project construction .
