yts

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。

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。

After heat treatment , UTS and YTS of RS bars did not change obviously , the E % improved 5.6 times .

热处理后，快速凝固挤压棒材的抗拉强度和屈服强度均没有明显变化，伸长率却提高了5.6倍。

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。

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。
