We've got a YTS girl helping us. 我们获得参加青年训练的一个姑娘的帮助。
A lot of YTS players end up falling by the wayside. 许多的青训营的球员最后都被淘汰了。
Being etched with acid apueous solution, this alloy can be activated and hydrogenized easily, and yts kinetics is improved. 酸性水溶液浸蚀时该合金易活化和氢化,且改善了它的动力学特性。
DF is widely used in machinery, electronics, optica and medical science due to yts high hardness, chemical stability, special characteristic of infrared penetration and high electrical resistance. 金刚石薄膜由于其极高的硬度和化学稳定性,并且透红外光特性和电阻率高的特性,广泛应用于机械、电子、光学、医学等领域。
The improvement of YTS is attributed to the grain refinement strengthening of Y and Zn, and to the solid solution strengthening of Zn. The reduction of UTS and elongation are caused by the precipitation of a compound phase along the grain boundary. Y、Zn元素的细晶强化及Zn元素的固溶强化是屈服强度提高的主要原因;抗拉强度和延伸率的降低是由于化合物相沿晶界析出。
The results show that the addition of Y and Zn improves YTS values but decreases the UTS and elongation values of as-cast alloys. 结果表明:Y、Zn元素提高了合金的屈服强度但降低了抗拉强度和延伸率。
Teachers were divided into 2 groups of YTs and ETs according to their teaching years. 八名老师根据其教龄分为两组:年轻组和经验组。
