1·We dealt with Young's modulus.
我们对付的是杨氏模量。
2·The speed of sound also depends on Young's modulus.
声速也同样，取决于杨氏模量。
3·Without proof-- - you will see this if you ever take 803-- I will tell you that the speed of sound is the square root of Young's modulus divided by the density of the material.
现在不证明-,你们将在803章学到-,我告诉你们声速,是杨氏模量的平方根,除以介质的密度。
4·If Young's modulus is very low, the material is more elastic.
若杨氏模量很低，物质更有弹性。
5·So this is Young's modulus.
这是杨氏模量。
1·The results show that the hardness and elastic modulus increase as the sputter power increases.
经实验结果显示其硬度与弹性模数皆会随著溅镀功的增加而增加。
2·"Speech" Two white wooden supports of different modulus can turn into a speech sitting stool.
“演讲”两个白色木质支撑不同模数的盒子可以变成演讲听众椅。
3·It has a rolled, rigidized surface which gives it a high modulus of rupture and compressive strength as well as high abrasion and hot gas erosion resistance.
它具有滚压刚化表面，不仅断裂模数大、耐压强度高，而且具备良好的抗磨损和抗热气腐蚀能力。
4·Cracks frequently generated in basin gear of big modulus main reducer used in heavy load truck after carbonizing and quenching.
大模数重载汽车主减速器盆形齿轮经渗碳淬火后，齿轮齿面经常会出现裂纹。
5·Such as sand not clean (mud high content), sand the fineness modulus too high or too low, also can make the strength of concrete is reduced, and the water increased.
如砂石不干净(泥含量较大)、砂的细度模数过高或过低等，也会使混凝土强度降低、泌水性增加。
