中文摘要：

就在区域，精确，在国家、省、城市的伪大地水准面之中存在的资料和决定的差别而言，象资料转变和 weighting 那样的一些方法在这篇论文根据精确被介绍与不同区域，精确，资料和决定使伪大地水准面模型正常化。这样，伪大地水准面的无缝的拼接被认识到。

英文摘要：

Considering the differences in area, precision, datum and resolution existing among the national, provincial and urban quasi-geoids, some methods such as datum transformation and weighting according to precision are presented in this paper to normalize the quasi-geoid models with different areas, precisions, datums and resolutions. In this way, the seamless splicing of quasi-geoid is realized.
