radius of particle

when the distance is equal to the radius of particle, the joule heat is largest. when the distance is larger or smaller than the radius, the joule heat will decrease.

在较低体积分数下，当颗粒间的距离等于颗粒半径时，颗粒间焦耳热最大，颗粒间距小于或大于颗粒半径，焦耳热都会减小。

The effective radius of cloud particle is larger and optical thickness of aerosol is large, which were reflected by CH1 and CH3 reflectance.

卫星数据表明，此时雹云与其它云团不同，具有粒子有效半径较大，气溶胶光学厚度也大的特点。

The out-of-focus radius is proposed to evaluate quality of the restored image. Simulation results on synthetic and real images demonstrate that the restoration method satisfies the requirement of crack identification for magnetic particle testing system.
