| 摘 要： | 通过抛射筛数学模型建立的因素分析，描述了在这建模过程中众多因素对透筛概率的影响，指出颗粒能否透筛是一个复杂的过程。颗粒透筛的几何概率仅反应颗粒与筛网接触一瞬间的透筛现象，在此之前还有其它因素对颗凿的运动产生影响。大型抛射筛数学模型的建立过程，考虑了颗粒在筛分过程中运动规律及透筛概率规律。

| Abstract: | The screening probability was affected by many factors that was described in the factor analysis during to establish the mathematical model of projectile screen. Particles' matter through screen is a complex process. The geometry probability of particles' matter through screen was only shown that was happened in a twinkling when the particles contact with screen. Before it happens the other factors also effect on the particles' movement. The movement and through screen probability pattern during screening process was considered when to establish the mathematical model of projectile screen. |
