Preparation and properties of the SmOx/Rh(100) model surface

The preparation of SmOx/Rh(100) and CO adsorption on this model surface have been investigated with Auger electron spectroscopy (AES), X-ray photoelectron spectroscopy (XPS) and temperature programmed desorption spectroscopy (TDS). The oxygen adsorption on the SmRh alloy surface leads to the aggregation of Sm on the surface. The thermal treatment of this oxidized surface induces the further agglomeration of SmOx on the Rh(100) surface. Compared with CO TDS on the clean Rh(100) surface, three additional CO desorption peaks can be observed at 176, 331 and 600 K on the SmOx/Rh(100) surface. The CO desorption peak at 176 K may originate from CO adsorbed on SmOx islands, while the appearance of the CO adsorption peaks at 331 and 600 K, depending on the oxidation state of Sm, is attributed to CO species located at the interface of SmOx/Rh(100).

摇椅形唇弓单独使用或联合平面导板矫治深覆

单独采用摇椅形唇弓或联合平面导板的方法,对２１例恒牙列期安氏Ⅱ类Ⅰ分类的低角型前突型深覆牙合患者进行了矫治,以观察两种方法临床疗效的异同。结果表明：１）摇椅形唇弓与平面导板联合使用有利于深覆牙合面型的改善,缩短了打开深覆牙合的时间;２）两种方法对牙齿的松动度及颞下颌关节（ＴＭＪ）的影响无显著性差异。对于低角型的深覆牙合患者,摇椅形唇弓与平面导板矫治能取得更好的临床疗效。
