We obtained the infrared reflection spectra of Pr〓Y〓 Ba〓Cu〓O〓 system for the first time, in which the existence of Pr〓 is confirmed and found the reason, which the superconductivity descends along the increasing of the content of praseodymium, should be the great decrease of the carrier density.

我们首次对Pr〓Y〓-〓Ba〓Cu〓O〓进行了系统的红外光谱研究，证明了Pr的价态接近于+4，有效地解释了该体系随Pr含量增加超导性减弱的原因，在于载流子极大减弱。

I read with interest -but it would probably be more honest to say I browsed, since I could understand less than 50%- a preprint released three days ago on " The hidden charm decay of Y(4140) by the rescattering mechanism ", by Xiang Liu, from Peking University.

我阅读兴趣，但它可能会更加诚实说，我浏览，因为我能理解小于50 ％-一个预发布3天前的"隐藏的魅力衰变的Y（ 4140 ）的rescattering机制"，由项留，来自北大（现在在科英布拉， Pt ）的。

The geochemical characteristics of basic to intermediate-basic igneous rocks indicate that they belong to a tholeiite suite. Their chondrite-normalized REE patterns are of nearly flat and slightly LREE-enriched type, and their primitive mantle-normalized and MORB-normalized trace element spidergrams are generally similar; the LILEs Cs, Ba, Sr, Th and U are enriched, while Rb and K and the HFSEs Nb, P, Zr, Sm, Ti and Y are depleted. All these show comagmatic evolutionary and genetic characteristics.

基性—中基性岩浆岩的地球化学特征表明其属于拉斑玄武岩系列，稀土元素分布型式呈REE近平坦型—LREE轻微富集型，微量元素原始地幔标准化的蛛网图和MORB标准化蛛网图上的分布型式总体很相似，富集大离子亲石元素Cs，Ba，Sr，Th，U而相对亏损Rb，K和高场强元素Nb，P，Zr， Sm，Ti和Y，显示同源岩浆演化成因特征。

Thus a simple method is proposed for determining the value of reference node coordinate, that is to derive the cross-point of coordinate equation of Y, which represents the principal inertia plane and the one perpendicular to the other plane.

为此提出了一种参考节点坐标值的简易确定方法，即通过求解代表主惯性平面和与主惯性平面正交的另一平面同Y轴的交点坐标方程，根据抽油机支架上角钢的结构方式，取代数值较大的一个即可确定参考节点的位置。

He said the Y chromosome is deteriorating and will disappear, and the technology for women to procreate without men is just around the corner.

他说，Y染色体正在退化并将消失，而不久的将来会有这样的技术，让女人在没有男人的前提下也能生孩子。

Likewise, if he picked X over Y, a colonoscopy over an enema, pushpin over poetry, his choice should be respected.

同样的，假如他选择了X放弃了Y，选择了结肠镜检查放弃了灌肠，选择了彩头图钉放弃了诗歌，他的选择应该得到尊重。

This paper reviewed the advances of noise barrier structure in China, and illustrated the development of multiple-edged, T-shaped and Y-shaped top structures used for noise barriers abroad. The development of some new top structures, such as soft surface, quadratic residue diffusers surface of noise barriers was also introduced.

作者对国内声屏障结构形式的现状进行了分析，介绍了国外常见的多重边、T型、Y型等顶部结构的发展情况，同时介绍了声学软表面、平方余数序列表面等新型顶部结构的发展状况。

The monolayers of LPSQ can be successfully transferred onto hydrophobic surface of silicon wafer or quartz plate to develop a very stable and uniform Y-type Langmuir-Blodgett film when using toluene as the spreading solvent at proper surface pressure.

在适当的表面压下，以甲苯为铺展溶剂该单分子层可以被成功地转移至疏水的硅片或石英片上形成均一稳定的Y-型LB膜，其紫外吸收强度在几个月内均保持不变，说明该LB膜具有良好的稳定性，AFM图像表明其形成了均一致密的膜。

If xi + y is a complex number, then think of a quaternion as a very complex number.

假如xi + y是一个复数，那么我们可认为四元数是一组很特别的复数。
