节约用料 meaning in Chinese

economy of material
material saving

Furthermore , referring to the literature and considering the specific experimental conditions given by the research , expression of the change of feed rate with time is presented , to obtain the linear growth of the diameter of pre - sintered glass beads , thus the distribution of beads size is relatively well controlled and raw material is spared in some extent . eventually , during the experiment discrete change of feed rate is implemented , and the practical changes of average diameter are plotted , then the results are compared with the theoretical calculated data
另外，本文通过对造粒技术、烧结过程的大员文献调研，结合本研究的具体情况，通过控制进料速率呈连续性变化，基本实现了烧结前球坯直径的线性生长变化，从而更有利于实际生产中的产品粒度控制以及做到节约用料，并在试验操作中以离散型进料速率变化来加以比较验证。
