    Description: 基于电磁场的多尺度变换理论,将一个各向异性介质椭球重构为一个各向同性介质椭球,进一步得到了新椭球的形体参数.利用各向同性椭球电磁场与各向异性椭球电磁场的多尺度关系,得出了各向异性介质椭球内电场的解析表达式,对所得结果进行了验证.计算了椭球内电场方向与外电场方向的夹角,仿真结果表明:外电场的方向对椭球内电场的影响不大,介电常数张量对椭球内电场的方向和大小有较大的影响.

    Description: [目的]探讨治疗老年急性梗阻性化脓性胆管炎的有效方法。[方法]共45例.随机分2组,两组均在全麻下手术,解除梗阻和胆道引流,中西医结合治疗组24例另用大柴胡汤合茵陈蒿汤加减治疗。[结果]两组病例治疗前后临床症状、体征消失,WBC、ALT、血胆红素恢复正常方面有显著差异(P〈0.01)治中西医结合疗组优于单纯西医治疗组。[结论]大柴胡汤舍茵陈蒿汤治疗老年急性梗阻性化脓性胆管炎有明显疗效。
    Description: [Objective]Explore the effective treatment for senile acute obstructive pyogenic cholangitis, [Method]Randomly divide 45 cases into 2 groups, operate under full anesthesia to remove the obstruction and make biliary tract drainage, the treatment group 24 cases with combination of TCM and western medicine(WM)are treated with revised Major Bubleurum Decoction and Capillaris Decoction. [Result]For both groups, the clinical symptoms and signs disappear; WBC, ALT and the recovery of blood bilirubin are much different,the treatment group of combination of TCM and WM was better than the WM group. [Conclusion] Major Bubleurum Decoction and Capillaris Decoction has marked effect in treating senile acute obstructive pyogenic cholangitis.

    Description: 以硅钢叠片为强性层,以含MoS2、石墨和环氧树脂构成的复合自润滑材料为塑性层,采用叠装-粘接工艺制备了强性层-塑性层相间的叠层复合材料.通过控制叠片数量,得到了塑性层含量可调的叠层复合材料.采用球-盘摩擦实验机对叠层复合材料的干摩擦性能进行了评价,结果表明:与无塑性层的叠层复合材料相比,含塑性层的叠层复合材料的摩擦学性能得到了明显改善.在载荷为6N、往复频率为4 Hz的条件下,塑性层的面积比为40%的叠层复合材料的摩擦系数为0.15,磨损率为3.8×10-7 mm3/(N·m),比无塑性层的叠层复合材料分别降低了76.7%和96%.由磨痕表面的能谱分析发现,叠层复合材料的强性层表面含有C、S、Mo等元素,而在塑性层表面含有Fe、Si等元素,表明在摩擦热作用下塑性层的润滑剂渗出,并转移到摩擦表面形成转移膜,同时塑性层具有嵌藏金属磨屑的能力.在强性层与塑性层的协同作用下,叠层复合材料具有优异的耐磨减摩性能.
