坐标图中,为了避免坐标标尺数中出现过多的零,常将乘数用于坐标轴的标记中.例如:Years before present(×10~9)(Nature 331:613图2;1988)Age of surface(×10~9 yr)(Nature 331:612
For example, Years before present (× 10 ~ 9) (Nature 331: 613 Fig. 2; 1988) Age is used in the coordinate graph to avoid excessive zeroes in the coordinate scale of surface (× 10 ~ 9 yr) (Nature 331: 612
