阳极化铝光干涉电解着色的研究

用Ｌ２－ＬＤ３１铝材进行了青铜色以外颜色电解着色的研究。通过本文较为系统的工作找到了磷酸扩孔和锡盐着色适宜的条件，获得了除蓝色以外的比较稳定的红、黄、绿色，并且耐磨、耐晒和封闭的质量敢可达到基本合格要求。用磷酸阳极氧化和酸化的Ｎｉ－Ｃｕ着色液或用酸性铜着色液可获得纯正蓝色的干涉色薄膜。

The Role of Metastable Atoms in a Homogeneous Atmospheric Pressure Barrier Discharge in Helium

A one-dimensional fluid model for homogeneous atmospheric pressure barrier discharges in helium is presented by considering elementary processes of excitation and ionization including a metastable atom effect. Using this model we investigate the behaviours of the helium metastable atoms in discharges as well as their influence on the discharge characteristics. It is shown that the metastable atoms with a relatively high concentration during the discharge are mainly produced in the active phase of the discharge and dissolved in the off phase. It is also found that the metastable atom collisions can not only provide seed electrons for discharges but also influence the concentration of ions. A reduction of matestable atom density results in a drop in the charged particle densities and causes a qualitative change in the discharge patterns.     

A Ray-Tracing Analysis of ICRH in Tokamaks

Power deposition profiles generated by Ion Cyclotron Resonance Heating （ICRH） in non-circular tokamaks are studied using a ray-tracing technique. The simulation results for the Experimental Advanced Superconductor Tokamak （EAST） D-shaped plasma are presented. It is indicated that the spatial distributions of plasma parameters （plasma density, species temperature, minority ion concentration, etc.） have an significant influence on the power deposition profiles. The findings may be highly useful to the planned plasma heating and experiments in EAST.
