permeable media meaning in English
可渗透介质
Examples
- First , according to the demand of vimp for resin system , the reaction kinetics and rheological of up resin are investigated and the optimal content of low additive profile ( lpa ) is determined . then vimp based on a high - permeable medium and grooves are studied by visual experiments , through which the appropriate high - permeable mediums are selected and the parameters of width , depth and spacing for flow grooves and spacing for supply grooves are optimized . furthermore , various factors affecting the mold filling process are discussed and the whole vacuum infusion procedures are described taking examples of the manufacture of a model boat and a sandwich panel in one infusion
文中首先根据vimp对树脂体系的要求，对vimp用不饱和聚酯树脂体系的动力学和流变学性能进行了研究，确定了最佳低收缩添加剂的含量；对高渗透介质型和沟槽型vimp开展了实验研究，通过可视化实验优选出较好的高渗透介质，确定了引流槽的宽度、深度和槽间距及主槽的槽间距等工艺参数并进行了优化；对影响充模过程的各种因素进行了详细的讨论，并以模型船和夹芯面板的制作为实例描述了两种vimp的成型过程；在实验的基础上，建立了二维渗漏模型，采用控制体有限元法对高渗透介质型vimp进行了成型过程的计算机模拟计算，通过充模时间和流动前峰的计算值与实验结果的比较，验证本文所采用的数学模型和数值方法的正确性，其结果对实际生产具有一定的理论指导意义。
