The computed rock compressive strength with the established regression model can support exact compressive strength for the establishing of sand prediction model for oil well.
利用该回归模型进行抗压强度的计算，可以为建立油井出砂的理论预测模式提供较为准确的岩石抗压强度数据。
2
The strength is calculated by the transfer matrix method and stability is computed by spline energy method.
强度分析采用迁移矩阵法，稳定性分析采用样条能量法。
3
The structural strength and flexural rigidity of the fuselage main frame are computed and verified by CAE system software and the results are analyzed.
