undulation of the geoid的意思|示意

The maximum difference of geoid undulation between the model and EGM96(to 70 degrees) is 2.

该模型与EGM96相比（70阶次），大地水准面起伏差异最大为2。

The results show that within the Philippine Sea and the South China Sea, short - wavelength lineations of the geoid undulation are parallel or cross to magnetic lineations and rifting ridges.

结果表明，菲律宾海和南海显示了与磁条带、扩张脊对应或斜交的高频成分大地水准面起伏条带。

The geoid undulation diagrams in different degrees are mapped by WDM94 model. The relationship between the geoid undulation and the lateral inhomogeneity of regional tectonics is discussed.

利用WDM94模型编制了华北地区不同阶次的大地水准面起伏图，讨论了大地水准面起伏和该地区构造横向不均匀性的关系。
