【摘要】 全球不少高原的高程异常(大地水准面起伏)为负,到底是正是负?需要从理论上求证。为此,推导了与此有关的高程异常的正负判别公式,并得出异常是由地球内外扰动物质引起的。该结论在模型计算中也得到了验证。此外对地形在计算高程异常中的作用进行了阐述。更多还原

【Abstract】 There are many plateaus with negative heigth anomalies(geoid undulation) around the world,they are really positive or negative? It needs to be proved theoretically.We have derived the positive and negative discriminant of the elevation anomalies,which result form disturbing matters inner and outer of the earth.The conclusion is also proved from model calculation.Moreover,the effects of terrain in heigth anomalies calculation are expatiated.更多还原
