The prior cycles with higher axial stress and larger strain range greatly restrains ratchetting strain of subsequent cycling with lower ones. Creep behavior plays an important role in the ratchetting strain and its influence on ratchetting behavior can not be neglected. Fracture morphology characteristics of two kinds of materials were investigated by scanning electron microscope. It shows that failure of material A is induced by cavitation and that of material B is induced by decohesion. For material A, with the decreasing strain amplitude the fracture surface shows more larger diameter globular particles under uniaxial loading and can be seen more obvious and deep crack under multiaxial loading. However for material B, with the decreasing strain amplitude fracture surface shows larger and larger scalelike shape and becomes more smooth under uniaxial loading, but fracture surface under multiaxial loading looks like more smooth than that of uniaxial loading, and shows gradually wave-like morphology.

通过扫描电子显微镜研究表明：材料A为空穴引起的失效，材料B为剥离导致疲劳破坏；随着载荷幅值的减小，材料A在单轴载荷下，断口表面浮出更多更大直径的球状颗粒，而多轴载荷下，可以看到很深的裂纹；随着载荷幅值的减小，材料B在单轴载荷下，断口表面鱼鳞片越来越大，表面越来越平整，而多轴载荷与单轴载荷相比，断口表面看上去更加平整，并且随着载荷幅值的减小，断口逐渐呈现波浪形貌；通过微观的傅立叶变换红外光谱分析，结果表明随着应变幅值的增加，无论载荷是单轴还是多轴状态下，橡胶材料吸光度比值随着幅值的增加而增加，这说明体系中的结晶含量也随之增加。

It was confirmed by Log-rank test that the cardiac allografts in group B and group C all survived longer than those in group A significantly (p.01). The survival time of the cardiac allografts in group C was also longer than those in groups B (p.05), which suggested that the recipients which pretreatment with SPC and CP was more efficient than that with CsA.(2)TGF-β1 is expressed as buffy granules in cardiac muscle and blood vessel dissepiment.
