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.

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。

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。

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。

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。

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。

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。

Consistent with the expression patterns of the YUC genes, the freeauxin/ IAA levels in embryonic calli were also increased.

与YUC基因的表达模式一致，生长素IAA的水平也是上升的。

I still think he looks like Yul Brynner.

METHODS: HPLC, colume: YWG C 18 ( 4.6mm × 250mm, 5 μ m), mobile phase: methanol 0.25% phosphoric acid ( 80 ∶ 20), wavelength: 436nm, flow rate: 1.1ml/ min, column temperature: room temperature.

方法：用高效液相法测定，选定YWG C18分析柱（4.6mm×250mm，5μm），流动相：甲醇0.25%磷酸（80∶20），检测波长：436nm，流速：1.1ml/min，柱温：室温。

Methods The chromatographic conditions included a column YWG C18, mobile phase: methanol-water ( 50 ∶ 50), adjusting to pH 3.0 by 0.3% triethylamine solution and phosphoric acid, flow rate 1 ml/ min, and wavelength 230 nm.

流动相为甲醇-水（50∶50，含0.3%三乙胺，磷酸调pH3.0）；流速1ml/min；

Conclusion: YWG can protect the gastric mucosa and repair its damage by regulating the secretion of gastrointestinal hormone.
