In this paper, some improvements have been made on the traditional gradient interpretation methods for the two-dimensional fault gravity anomalies:① The least squares fitting technique is adopted to figure out the dip angleαof the step;② The dip angle and the horizontal boundary of the step are directly used to calculate the burial depth of the step;③ the interpretation method for gravity two-dimensional gradient is extended to the interpretation of the complex fault model.

摘要对以往的二维断裂重力异常的梯度解释方法作了几点改进：①采用最小二乘拟合方法求取台阶倾角α；②直接利用台阶倾角与台阶的水平边界位置来计算台阶的埋深；③将重力二维梯度解释方法推广到复杂断裂模型的解释。

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.
