Two sorts of backfills, bentonite and cement boned sand, have been tested in the laboratory for the system by unstable state method.

其主要缺点是地下换热器的初投资较高，这也是阻碍地源热泵技术发展的主要原因之一[1 ] 。

This paper introduces experiments on the influence of the cement type, sand type, sand size, and bentonite content on the thermal conductivity of the borehole backfills, and aslo the influence of the bentonite content on the backfill consistency.

实验研究了水泥型号、骨料类型、骨料粒径、膨润土含量对回填材料导热系数的影响，以及膨润土含量对回填材料稠度的影响。

The research result indicates that the thermal conductivity of the Cement PO42.5 is slightly higher than that of the PO32.5 and the thermal conductivity of the borehole backfills increases when the sand size increases,and that contained quartz sand is higher than river sand.At the same time,the thermal conductivity of the borehole backfills increases firstly and then decreases and the consistency decreases when the bentonite content increases.

研究发现：PO42.5水泥的导热系数稍大于PO32.5的导热系数，回填材料导热系数随砂子粒径的增大而增大，骨料为石英砂的回填材料导热系数要明显大于骨料为河砂的导热系数；同时回填材料的导热系数随膨润土含量的增加先增加后减小，回填材料的流动性随膨润土含量的增加有所降低。

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。
