On the basis of summarizing and discussing the gamma inversion, we point out that an analytic method of volume attribute is very important. The method integrates multiple stepwise regression and cross verification to optimize and combine the attribute, adopts the convolution factor to eliminate frequency difference between the seismic and logging data, uses the neural network as a matching and predicting tool. Because of its religious theoretic base, the method is more accurate than other ones.

在对目前常用的伽玛反演方法进行总结、讨论的基础上，指出地震体属性分析法具有明确的物理意义，有效结合了多元逐步回归和交互验证法进行属性的优选和组合，采用褶积因子消除地震信息和测井信息的频率差异，并以神经网络为拟合和预测手段，具有严谨的理论基础，相比其它几种方法更为准确合理。

They are the carry-over of the streams, the sediment releasing and the carry-over of the water from Qiantang River. Estimated the total phosphorus data of them as the boundary condition in calculating, Then according to the actual water diversion and water distribution of the West Lake of the four seasons in 2004, the source of total phosphorus and the data of the 11 concentration field measuring point, inversion analysis was carried out, then the comprehensive sedimentation constant k was obtained.

以总磷为模拟指标建立了水质模型，在入湖总磷负荷来源分析及测算的基础上，确定了西湖总磷的主要来源为入湖溪流携带、西湖底泥释磷、钱塘江引水携带，并测算了具体的数值作为浓度场计算的边界条件。

In this paper, the analytical solutions of reservoir pressure in Laplace space are developed for planar linear flow and radial flow under the condition of constant pressure at inner and outer boundaries, and the pressure distribution curves in some point in the reservoir are obtained using Stehfest numerical inversion algorithm of Laplace transforms.

本文在内、外边界定压的条件下得到了平面单向流和平面径向流两种渗流形式在拉氏空间的解析解，利用Ste hfest数值反演方法给出了地层各点的压力分布曲线，由这些曲线可以清楚地看到流体的流动由不稳态流向稳态流过渡以及最后达到稳态流的过程。

The explicit solution of the strain energy release rate of crack propagation along the pure bend sandwich beam specimen has been deduced in the paper by use of the superposition principle of the energy and section inversion method.
