1.Principal component analysis (PCA) and minor component analysis (MCA) provide powerful statistical techniques in many information processing fields such as image processing, direction-of-arrival problems, communication technology, and so on.
2.Minorprincipal stressσ3 got from anisotropic model is larger than that from Duncan E-v model. It is proved that the estimate of the hydraulic fracturing of earth core dams with Duncan E-v model will be more dangerous.
