The precise of velocity analysis is controlled by the approximation formulas of moveout curve and the analysis method 决定速度分析的精度的主要方面有时距曲线拟合公式的精度和速度分析的具体实现步骤。
In order to illustrate the valid range of the axial intensity expression and approximation formulae numerical results of both the methods are compared 使用轴上光强公式和近似公式对焦移计算结果的比较证明了近似公式的适用范围。
We simply discuss those which are of importance to realizftg bandwidth requirement and with an approximation formula , the bandwidth is estimated 本文简单地分析了实现带宽要求的主要因素,并应用近似公式对带宽作出了估计且表明带宽要求是可以实现的。
By analysing the compute result of the quadratic approximation formula , we educe the conclusion that 3 is the best rank code for the quadratic approximation formula 通过对最小二乘拟合公式实际计算结果的分析,得出了“拟合公式阶数取3为最佳”的结论。
