Zhongshan Daxue xuebao. Yixue kexue ban, 1993 报告84例经鼻中隔,蝶窦入路摘除蝶鞍区肿瘤手术方法及效果。术前检查有单纯性鼻炎2例,过敏性鼻炎2例;鼻中隔C型弯曲或嵴突32例;全鞍型蝶窦79例,甲介型5例;蝶鞍正常53例,扩大者31例,其中鞍底有破坏的占12例。鞍内肿瘤病理诊断,垂体腺瘤81例,垂体囊肿1例,颅咽管瘤2例。经鼻小柱-鼻中隔-蝶窦行鞍内肿瘤手术,暴露病灶清楚、准确,并发症少,效果良好,无1例死亡。作者认为鼻中隔软骨保留,筛骨垂直板及犁骨仅部分去除,可以减少并发症。术后随访2个月～5年,合并症仅鼻中隔穿孔1例,鼻中隔血肿1例,鼻腔粘连2例,

Dianci bileiqi氧化铝陶瓷因其优异的力学性能和耐高温性，在机械、电子、航空航天等领域应用广泛。但纯Al2O3陶瓷在烧结中易发生晶粒异常长大和气孔残留，限制了性能提升。本研究以MgO为结构稳定剂，采用L9（34）正交实验，系统考察MgO掺杂量、保温温度、保温时间及降温速度对氧化铝复相陶瓷微观结构、力学及介电性能的影响。通过XRD、SEM表征物相与断口形貌，测试三点弯曲强度、维氏硬度及介电击穿强度。结果表明：掺镁试样三点弯曲强度最高提升105.66 MPa，维氏硬度达15.83 GPa。极差分析显示 ...
