ABSTRACT The aim of the project is to prepare the high temperature superconducting thin films which can satisfy the need of future applications in the field of power transmission. By using biaxially textured Ni (001) and Ag (110) as substrates, the YBCO films with high critical current were obtained under the optimized deposition conditions. Some results were obtained as follows: We developed a simple approach to prepare YBCO films doped with Ag nanograins.

本工作的研究目的是在金属基带上制备出能够满足未来超导强电应用的超导薄膜小样品，其具体的做法是在双轴织构的Ni（001）和Ag（110）基带上外延YBCO高温超导薄膜，经过不断地优化工艺条件，我们得到如下结果：发展了一种在YBCO薄膜中掺入Ag颗粒的方法，这种方法具有可以随时改变掺杂量的特点。

In this thesis, the resonance fluorescence spectra of a A-type three-level atom is calculated, which is driven by two bichromatic fields having the same difference of the frequency. In addition, the influence of the relative phase difference on the fluorescence spectra are considered. It is found that the fluorescence spectra of the atom are deeply depend on the relative difference and the appearance and cancellation of the fluorescence are obtained by changing the relative phase difference.

文中以具有相同频差的两个双色场驱动下的三能级Λ型原子为模型，计算了其共振荧光谱，考虑了两个双色场的相对相位差对谱线的影响，结果表明：原子的荧光谱强烈地依赖于驱动场的相对相位差，可以利用相对相位差的改变对荧光的产生和抑制加以操纵。

The iMac G5's appearance hasn't changed much from the previous version: Sharp-eyed users will notice the now-curved back panel, which makes the iMac seem more organic and less bricklike than the previous version.
