目的探讨小儿输卵管卵巢扭转的临床特征和诊治要点。方法对收治的62例患者进行回顾性分析。结果所有患者表现有下腹痛，病程2h至半年不等，48例可查及下腹压痛；彩色多普勒超声检查均发现在盆腔一侧有不均质肿块，其中30例提示有扭转可能。所有患者均行手术治疗，其中行腹腔镜手术者14例；术中见47例为右侧附件扭转，15例为左侧扭转；渗出粘连明显者24例；35例行患侧附件切除，27例行附件复位、肿瘤剔除和冰冻切片检查后保留附件。在保留附件患儿中，有22例得到随访，除1例卵巢萎缩外，其余21例卵巢功能均良好。结论小儿输卵管卵巢扭转较少见，无特殊临床表现，易致误诊。一经诊断应立即行手术探查，扭转的附件应根据扭转时间、供血障碍程度、病变性质来决定取舍。

提出了一种新型的基于环形电桥结构的宽带平面和差网络。首先提出了一种新型的宽带微带/槽线转换结构,然后将该结构引入到传统的环形电桥结构中,优化设计了一种改进型环形电桥,最后采用四个改进的环形电桥构建了双平面和差网络。测试结果表明:在4.05～7.425GHz的频率范围内,八个端口的驻波均小于2,输入端口之间的隔离度均在20dB以上,输出端口之间的隔离度大于30dB,和端口的插入损耗小于0.5dB,差端口的零值深度小于-30dB。该和差网络具有性能优良、结构简单、制作成本低等优点,在宽频带单脉冲雷达天馈系统中得到了成功的应用。
