By using high-resolution reference data to identify accurate GCPs, considering the spacecraft attitude deviations which TBUS can't supply, and adjusting the epoch time and ephemeris data at the criteria of constraint LeastMean-Square-Error, the geolocation accuracy of navigation for AVHRR data can be improved greatly.

由于采用具有足够定位精度的高分辨率参考图象以提取高精度的地面控制点，考虑了TBUS轨道报所不能提供的卫星姿态偏差，对历元时刻和卫星轨道根数进行有约束条件的参数最优调整，可使整条轨道大范围内的AVHRR导航定位精度有较大提高。

With adjusting the epoch time and ephemeris data at the criteria of constraint Least-Mean-Square-Error, the geolocation accuracy can reach 2 pixels in the whole images; and it can be improved to approximately 1 pixel in the whole images and less than 1 pixel at nadir by considering the spacecraft attitude deviations moreover.

如果进行历元时刻和卫星轨道根数的约束最优调整，导航定位精度在整条轨道大范围内可提高到2个像元左右；如果再加入卫星姿态偏差的校正，导航定位精度在整条轨道大范围内可稳定提高到1个像元左右，在星下点附近小于1个像元。

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。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.
