The results indicate that the crystalline volume fraction (X_c) decrease firstly and then increase with the increase of excitation frequency.
结果发现材料的光敏性随频率的增加先降低后提高，晶化率和沉积速率的变化趋势与之相反；
In addition, with the increasing distance between the filament and the substrate, the crystalline volume fraction and the grain size of poly-Si films notablely decrease.
另外，随着热丝与衬底间距的增大，沉积出的多晶硅薄膜样品的晶化率明显减小，薄膜的晶粒尺寸也相应减小。
