Spherical particles have minimum scatteringarea, high packing density; which is beneficial to the luminescent intensity and lifetime of the devices.
球形颗粒荧光粉的光散射面积最小，堆积密度大，有助于提高发光材料的发光强度和使用寿命。

The theoretical models of point target, extended target and line target are established based on the concept of equivalent scatteringarea and laser ranging equation.
根据激光测距方程，引入了等效散射面积的概念，分别建立了对点目标、扩展目标和线形目标测距的理论模型。
