vertical line

Recently,resistivity method with vertical line source has been used to study the distribution of injection water and remain oil.

正演结果表明相同模型使用倾斜线源和直线源其地表响应有较大的差别,实际应用中不能将井斜较大的井当作垂直线源,而应以倾斜线源处理。

It is a simple and practical method to detect the underground dynamic conductor by vertical line source borehole-ground DC method.

在本文中,以垂直钻孔套管为垂直线源,介绍了垂直线源的地电场电位公式,给出了异常电位的变分问题。

A brief introduction of vertical linear array is presented in this paper.

简要介绍了三点垂直线阵被动定位的原理。

In this paper the measurement of sound velocity and thickness of seabed sediment are introduced using the vertical linear array which is concerned with sound refraction and reflection.

介绍了利用垂直线阵结合声传播的折射法和反射法进行海底沉积层速度和厚度测量,给出反射法和折射法测量的原理及其时距曲线方程。

However,in shallow water,because the arrival signals of the vertical linear array are not plane waves,the spatial gain needs to be estimated properly.

而在浅海环境中,由于到达垂直线列阵的声波并不满足平面波假设,其空间增益需要作出正确估计。
