The acceleration follows the mechanic principle, the proton energy increases with the laser intensity while it decreases when the target thickness and density increase.
加速过程符合力学原理,随着激光峰值强度的增加,质子束的能量也随之增加;

The main results are as follows:(1) The intensity parameters are more useful than the other parameters for indicating the intensity of associated solar proton events.
