The results shows that: as the fast ions numberα=0, ie., the ions number density reduces to the Boltzmann ion distribution, the solitary waves are all rarefactive, which are in good agreement with Ref. [81]. as the fast ions increases, the compressive waves can also exist in some special regions.

结果表明，当快离子数为零时(α=0)，即离子分布退化为玻耳兹曼分布时，该系统只允许稀疏形孤波存在，这与文献[81]的结论相一致；而随着快离子数的增加(α≠0)，在某些特定的区域，还会出现压缩形孤波。

But in early resorptive phase in GSB group. The change of BMD, BGP, D-Pyr/Cr and biomechanics index in OVX-PII group were the same as that in OVX-PI group, but the rising range of compressive strength limit in lumbar spine and bend load of femur is bigger than that of JGG, and GSB group. Dynamics osteoblast appeared in large numbers on the surface of os, we can observe the transforming process from osteoblast to osteocyte.

同期预防Ⅱ组的BMD、BGP、尿D-Pyr/Cr及生物力学指标的变化大体维持在预防用药12周时水平，但从数字上看腰椎椎体的压缩强度极限和股骨的弯曲破坏荷载两项的上升幅度均大于健骨颗粒组和骨松宝组，预防II组骨质表面出现成群活跃的成骨细胞，可见成骨细胞往骨细胞转化过程。

The numerical simulation results and the corresponding experimental results showed that the VMIB could represent the complete process of uniaxial compressive failure of rocklike materials.

最后通过数值模拟和试验验证，说明VMIB模型能够有效地再现岩石类材料的单轴压缩破坏过程。

During the processes of uniaxial compressive failure of rocklike materials, the weakness of local material stiffness was considered to result from the distribution density decrease of bond, which was induced by the local deformation in the micro scale.

岩石类材料在受压破坏过程中，宏观上局部刚度的降低是在微观尺度上虚拟键分布密度衰减的结果。

Under triaxial compressive conditions, with an increase of loading, the propagation and sliding of microcracks in rocklike materials become increasingly intense and lead to a serial of consequences, such as nonlinear stress-strain relationships, deterioration of elastic modulus, anisotropic deformation, volumetric dilatancy and irreversible plastic strain, etc..

三维压缩条件下，随着载荷的逐渐增加，岩石类材料内部微裂纹的传播与错动不断加剧，最终导致非线性应力－应变关系、弹性模量的减小、变形的各向异性、体积膨胀以及不可逆塑性变形等结果。
