常见例句

STUDY ON FATIGUE CONTRATEST OF NOTCHED WORKPIECE OF BOTH JOINT AND BASE Ti-ALLOY
钛合金焊缝与母材缺口试样疲劳对比试验研究
Through contratest, the influence of the filterability caused by change of L/d10 (in which L is the bed depth and d10 is the geometric mean size of the media) is been studied. When L/dio is 1400,the periodic quantity of water produce can reach 160m3 /m2;
通过对比试验，研究了滤层厚度与滤料当量粒径之比L/d_(10)对过滤性能的影响，当L/d_(10)=1400时，周期产水量可达160 m~3/m~2；
