常見例句

STUDY ON FATIGUE CONTRATEST OF NOTCHED WORKPIECE OF BOTH JOINT AND BASE Ti-ALLOY
鈦合金焊縫與母材缺口試樣疲勞對比試驗(yàn)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;
通過對比試驗(yàn)，研究了濾層厚度與濾料當(dāng)量粒徑之比L/d_(10)對過濾性能的影響，當(dāng)L/d_(10)=1400時(shí)，周期產(chǎn)水量可達(dá)160 m~3/m~2；
