地球内部构造模型对地震学、地球物理学、天文学、大地测量学等的研究有着重要的意义。布伦的地球模型 A 和 B 曾被广泛的应用。自五十年代以来在文献上发表的地球模型数量大增,这使得研究者们难于决定倒底选用哪一个模型为好,有时人们从一个模型中选用一些参量,从另一个模型中选用另一些参量,以这种方式选用的结果是自相矛盾的。1971年在莫斯科举行的国际大地测量与地球物理联合会的会议上讨论了这一问题,结果建立了由国际大地测量协会(IAG)和国际地震学与地球内部物理学协会(IASPEI)成员组成的“标准地球模型委员会”,由已故的布伦教授担任主席。其最初的工作是由几个小组分别
The model of Earth’s interior structure is of great significance for the study of seismology, geophysics, astronomy and geodesy. Burren’s Earth Models A and B have been widely used. The dramatic increase in the number of earth models published in the literature since the 1950s has made it difficult for researchers to decide which model to use, sometimes choosing one from a model and choosing from another The parameters, chosen in this way, are self-contradictory. This issue was discussed at the International Geodetic and Geophysical Union meeting held in Moscow in 1971 and resulted in the establishment of the International Geodesy Association (IAG) and the members of the International Association of Seismology and Geophysics (IASPEI) “Standard Earth Model Committee,” chaired by the late Professor Brunn. Its initial job was divided by several groups
