超导性

The properties of thin films have been investigated with modern analysis technique, such as AFM, SEM, XRD (X-ray diffraction) and Rocking curve. And the properties of YBCO thin film and its substrate and deposition temperature have been analysed, comparing with LAO substrates crystallization quality, YBCO thin film properties, such as morphology and degree of grain alignment, was concluded to correlate with the crystal orientation uniform of LAO substrate as revealed by XRD.

本文结合AFM、SEM研究YBCO薄膜的表面形貌，XRD、FWHM分析薄膜的结晶情况，并结合成膜温度和基片的质量进行一系列结构与性能的对比研究，发现LaAlO3基片的质量对YBCO薄膜的结构完整性有很大影响，不仅影响了薄膜的c轴取向性，而且影响了YBCO的超导性能。

It is shown that the Josephson junction can reflect the quantum coherences of the external QEMF and distinguish different nonclassical light fields.

研究表明，介观超导约瑟夫森结不仅能反映外加量子化电磁场的量子相干性，而且能区别不同种类的非经典光场。

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。

As examples, he gave the onset of microchip studies, and the discovery of high-temperature superconductivity.

作为例子，他给了微集成电路研究起始，和在高温超导性的发现上。

Third, we discuss is the competing between superconductivity and spin accumulation in the island.

第三，我们讨论在一个超导性的中央岛中，因为自旋堆积所造成超导性的破坏对穿隧磁阻所产生的影响。

Superconductivity means no electrical resistance , and that in turn means no wasted power.

超导性意味着零电阻，也就意味着没有能量的浪费。

We obtained an estimate of the third critical field for cylindrical superconductors, and proved that, as the applied magnetic field decreases from the third critical field, superconductivity nucleates first at the surface of the cylinder where the curvature is maximal; and also gave a mathematical theory to describe the surface superconducting state.

我们获得了柱状超导体第三临界场的估计，证明了当外磁场从第三临界场减弱时首先在柱面的曲率最大处出现超导性；给出了描述表面超导态的数学理论。

However the different alkali metal azides RN3 show different reactivity with β-MNCl, and the properties of the products such as superconducting fractions, the lattice constant, and stability against thermal or air, are very dependent on the kinds of alkali metals used.

但是，不同的碱金属叠氮化物具有不同的可反应性，其反应产物也具有不同的性质，例如超导体积百分率、晶格常数、热稳定性和在空气中的稳定性等都和碱金属离子有关。

What would he tell Judith and the children?

他将怎样告诉朱迪丝和孩子们呢？

I this is at that time, the opinion with peacockish true girl is full of in a heart.

这就是当时的我，一个心中布满虚荣的女孩子真实的想法。
