Based on the measure of sand geometry in M Block and comparison of results calculated with Spherical, Exponential and Gaussian Model, it is concluded that different variogram models get very different variogram range in major and minor direction.

在详细解剖M油田的砂体几何形态的基础上，对比分析球模型、指数模型和高斯模型的计算结果，3种模型计算的变差函数长变程误差15％，短变程误差25％，方向也不一样；同时运用不同模型计算的砂体体积亦有较明显的差别：砂体越发育，砂体连通性越强，不同模型计算的砂体体积相差越小；砂体越不发育，砂体连通性越差，不同模型计算的砂体体积相差越大。

On the condition of electric-longitudinal-optical phonon strong coupling in both two- and three-dimensional parabolic quantum dots, we obtain the eigenenergies of the ground state and the first excited state, the eigenfunctions of the GS and the first ES by using a variational method of Pekar type.

在电子-体纵光学声子强耦合情况下，我们采用Pekar类型的变分方法获得了二维和三维抛物势限制的量子点中的电子的基态和第一激发态的本征能量和本征波函数。
