Fifty rats in the model group underwent ovariectomy, while the other 20 rats in the control group had sham operations. Three months later, 10 rats in the model group and 10 rats in the control group were selected randomly to detect their body weight, uterus weight, BMD of the left femur and lumbar vertebra, biomechanical characteristics of the left femur, levels of serum Ca2 +, Cr, ALP, SOD, MDA and GSH-Px and serumal resistance to OH(superscript -).

The method of prediction on stochastical simulating 3D parameter field of rock mechanics is brought forward in this paper. Namely, rock mechanics parameters- curve obtained by known and limited conventional log materials is took as inputs of hard data;and seismic attribute data body, hydrating of mud shale and rock environmental parameters data is took as constraint of soft data. By simulating stochastically through optimizing algorithm of Sequential Gauss Simulation,dynamical data field of rock mechanics parameter of three-dimensional space are gotten, then log response of rock mechanics parameters in position of any point in space is predicted.
