| 1. | For cartographical purposes heights are necessarily recorded above the geoid (sea-level) .
就制图的目的来说，所以需记录的高程是高出大地水准面（海平面）的高程。 |
| 2. | In general the accuracy of geoidal heights, as given by spirit leveling, much exceeds that of any other system .
一般说来，水准测量测出的大地水准面高程的精度，远远超过任何其它方法的精度。 |
| 3. | Determination of fuxin quasi - geoid without gravity data
无重力数据情况下阜新似大地水准面的确定 |
| 4. | Cogeoid of the condensation reduction
压缩改正调整大地水准面 |
| 5. | Undulation of the geoid
大地水准面的起伏 |
| 6. | Determination of quasi - geoid in mainland china using geopotential model and gps leveling data
水准数据确定我国大陆似大地水准面 |
| 7. | Problem of piecing together between china mainland - geoid and altimetry - derived geoid in china sea area
我国海域大地水准面与大陆大地水准面的拼接研究 |
| 8. | But the data of them are ample so it will be effective to dive geoid by them
而地形资料和岩石密度资料既充足又可靠，用它们来精化高原山区的大地水准面会获得良好的效果。 |
| 9. | Finally , the ocean geoid of china is worked out with about six months topex / poseidon data
最后用20个周期的topex / poseidon数据解算出了中国局部地区海洋大地水准面起伏。 |
| 10. | The main factors to influence the geoid s rising and falling of the mountainous districts are the acute change of the landform and the asymmetry of the mass of landform and the density of rocks
影响高原山区大地水准面起伏变化的主要原因是地形的剧烈变化，地形量和岩石密度分布的不均匀。 |
