1·Carrying on the survey fight in some area of Chaoshui basin based on the survey system in high accuracy aeromagnetic gradient.

在引进高精度航磁梯度测量系统的基础上，对潮水盆地某地区进行航磁梯度测量飞行。

2·Aeromagnetic data downward continuation to sea level instead of Marine magnetic survey data can improve use capability of survey data.

采用航磁数据向下延拓到海面代替船测数据，可提高磁力测量成果的综合利用率。
