本文在大量水模拟实验的基础上,应用水力学原理建立了阶梯式浇注系统的物理模型,并进行水力分析和数学分析,为阶梯式浇注系统内浇道面积的计算提供了依据和方法。
Based on a large number of water simulation experiments, the physical model of stepped gating system was established based on the principle of hydraulics, and the hydraulic analysis and mathematical analysis were carried out to provide the basis and method for calculating the gated area of the ladder gating system.
