AbstractAIM: To analyze 32 cases of patients with recurrent pterygium and symblepharon retrospectively in our hospital and to explore the effectiveness of limbal stem cell transplantation combined with amino membrane transplantation.

目的：回顾性分析2002-01/2005-01在我院接受治疗复发性翼状胬肉合并睑球粘连的32例患者，探讨角膜缘干细胞移植联合羊膜移植治疗复发性翼状胬肉合并睑球粘连的效果。

The patients who receives pterygium resection+symblepharon dissection+limbal stem cell transplant ation+amino membrane transplantation have lower recurrent rate and less post-operative symptoms of stimulation. This surgery is an effective method in coping with recurrent pterygium with symblepharon.

Aiming at the currently shortage of XML streams quality detecting, this paper proposes a new forecasting method of XML streams quality by least squares support vector machines, which is used the method of XML keys' vector matrix as windows, and vector product wavelet transform to multilevel decompose and refactor the XML streams series, that can fulfill real-time checking demand of XML quality, and ensure constraint, consist- ency and integrality. For even more adapting net load, it proposes a control strategy by weight and adaptive adjustment to ensure XML streams quality.

针对当前XML数据流质量检测存在的不足，提出构建XML键的矢量矩阵作为窗口，利用矢量积小波变换多级分解与重构XML数据流，再结合最小二乘支持向量机对XML数据流质量进行预测的一种方法，满足XML数据流质量重构时实时检测的要求，保证XML数据的约束性、一致性与完整性；为了更好的适应网络负载，采取加权与自适应窗口调整等调度策略充分保证XML数据流的质量检测。
