RESULTS AND CONCLUSION: Osteoblast was fusiformed-shaped and had plentiful processes. Nucleus was orbicular-ovate and leaning to lateral side. Soma was large, and plasma was abundant. Alkaline phosphatase staining suggested that a great number of gray-black particles were observed in plasma, and some region was darkly stained.

结果与结论：成骨细胞呈梭形，多突起；细胞核呈卵圆形，偏于一侧；胞体大，胞浆丰富；碱性磷酸酶染色可见胞浆中含有大量的灰黑色颗粒，某些部位染成黑色，定量分析细胞内的碱性磷酸酶、骨钙素水平明显高于成纤维细胞；细胞免疫组织化学染色表明其主要合成Ⅰ型胶原。

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。
