以AlCl_(3)-NaCl-KCl低温熔融盐体系作为电解质,无水SnCl_(2)作为原料,对电沉积制备Al-Sn合金进行研究。通过扫描电子显微镜(SEM)、能谱(EDS)和X射线衍射仪(XRD)分析合金产物的形貌和成分组成;通过极化曲线法和摩擦磨损实验对合金产物的耐蚀性和耐磨减摩性进行检测分析;通过维氏硬度计和涂层附着力自动划痕仪对合金产物的硬度与膜基结合力进行表征。结果表明:当SnCl_(2)添加量为0.04~0.08 g时可制备出锡含量为10%~18%的中锡铝合金,最佳沉积温度为160~200℃、沉积时间为40~50 min、电流密度为40~50 mA/cm^(2);随镀层中锡含量的提高,其耐蚀性逐渐变差,而耐摩擦磨损性能先提高后降低,并在SnCl_(2)添加量为0.06 g,即镀层中锡的含量为14 wt%时有最佳摩擦磨损性能;沉积温度对合金镀层的硬度及结合力有很大影响,随沉积温度的升高,合金镀层的膜基结合力和硬度均呈现先提高后降低的趋势,当沉积温度为200℃时,其结合力和硬度最佳。

In this paper, we study quantum teleportation of atomic states via a hybrid entangled state （HES） involving an atom and a cavity field. And we investigate how to implement controlled phase （CP） gates between atomic internal states and coherent states of cavity field. We also discuss the methods of distinguishing coherent states [±α〉 in a cavity. Finally, a brief discussion about the feasibility of this scheme in experiment is presented.

An experimentally feasible scheme for implementing teleportation of multi-atom cat-like states in cavity QED is proposed. In the scheme the atoms interact simultaneously with a highly detuned cavity mode and are driven by a strong classical field, and the atomic state evolution is independent of cavity field state. Thus the scheme is insensitive to both the cavity decay and the thermal field, which is of importance from the experimental point of view. All the orthogonal and complete multi-atom GHZ states can be exactly distinguished only by one step, so our scheme can also be used for other purposes such as dense coding using multi-atom GHZ states as quantum channels.

We present a theoretical scheme for perfect teleportation of an unknown multipartite two-level state by a single EPR （Einstein-Podolsky-Rosen） pair, and then generalize it to multilevel, i.e., an N-quNit state can be teleported by a single quNit entangled pair, with additional local unitary operations. The feature of the scheme is that teleporting a multipartite state with a reduced amount of entanglement costs less classical bits.
