合力在离体牙实验性楔状缺损形成中的作用

中华口腔医学杂志 1995年第5期30卷 268-270页

本研究通过对不同因素所致离体人牙实验性楔状缺损的深度和形态变化的检测，探讨了力因素在楔状缺损形成的作用。将７名患者的９对离体双尖牙按不同力因素分成三组，各组牙齿仅颊侧牙颈部接受横刷牙实验，分别在ｐＨ５和７水浴条件下交替进行模拟力疲劳和横刷牙实验。分为四次间隔，总共进行１６０００００击力疲劳和８０００００回横刷牙实验。在各间隔期，用ＳｅｅＳｃａｎ计算机图象分析仪测量受试牙复制模型颈部缺损侧影的深度并记录缺损形状。结果证明，力在人牙实验性颈部楔状缺损形成过程中起重要作用。单独的力因素可非常缓慢地致牙颈部缺损，当横刷牙和酸蚀共同作用时，颈部缺损深度显著增加，并形成楔形缺损。

本工作用化学气相淀积方法在a.ln.s.i(100)复合衬底上生长s.iC薄膜。外延生长过程中,采用C4H4和s.iH4作为反应气源,H2作为载气。样品的X-射线衍射谱和拉曼散射谱显示,所得到的外延层为六角对称的s.iC薄膜。俄歇电子能谱及X-射线光电子能谱的测量结果表明,在外延膜中存在来自衬底的a.l和n.素。样品的光致发光测量显示,所有的样品均可在室温下观察到位于3.03 eV和3.17 eV处的发光峰,这分别相应于4H-s.iC能带中电子从导带到a.l受主能级之间的辐射跃迁和电子从n.主能级到价带之间的辐射跃迁,从而表明所得的外延薄膜的多形体为4H-s.iC。

美国为什么没有社会党——美国例外论面面观

从历史背景来说,美国的左派问题需同另一个始终存在的老问题联系起来:为什么美国成为唯一没有得以生存下来的社会党或工党的工业化社会;为什么它在政治上“例外”。一些分析家特别是左派分子在评述这一问题时,长期坚持说美国就政治观点而言是“落后的”,赶不上欧洲和大洋洲的意识形态和阶级觉悟。但这种提法从正统的马克思主义观点来看不啻奇谈怪论。马克思认为文化上层建筑特别是政治相应地产生自基础,亦即经济和技术体系。由于他确认社会主义理想、工人阶级觉悟是工业社会的结构性矛盾的固有产物,因此得出了一个社会工业和经济越是发达,就越是能产生强大而急进的社会主义运动的结论。马克思在
