研究人员发现几乎所有深度达到35公里的地震都可以通过电离层明显的电磁扰动现象预测到。
The researchers found that almost all of the earthquakes down to a depth of about 35km were preceded by distinct electrical disturbances in the ionosphere.
方法：利用电离室法测量平野、动态楔形野、物理楔形野的深度剂量和射野外周边剂量。
Methods: The depth doses and peripheral doses were measurement for open field and Enhanced Dynamic wedge field as well as physical wedge.
