positive anomaly

But Ce showed positive anomaly, the average value of δ Ce was 1.48, which was distinctly higher than that of Chinese soils.

而Ce表现出明显的正异常，δCe平均值为1.48，明显高于中国土壤平均值。

There is a positive anomaly area with above 120 nms-2 gravity change before the earthquakes, and the bigger the earthquake magnitude the more the gravity anomaly.

震前总有一个120nms－2以上的正异常区出现，震级越大异常区的幅值也越大；

The resultant Z_a magnetic anomaly map consists of two major magnetic anomaly zones: positive anomaly Zone in the north part and the negative anomaly zone in the south part.

由此得到的Z a磁异常平面图，北部为正异常区，异常很不规则，有三个局部异常；

Eastward component T shows weak positive anomaly in the studied region.

东向分量在整个区域呈现微弱的正异常。

Sr content of trace elements in there is a positive anomaly.
