In order to describe the fatigue damage characteristic under multiaxial proportional and nonproportional loading, a new nonlinear multiaxial fatigue damage cumulative model was presented on the basis of combining multiaxial fatigue damage characteristic. The recurrence formula of multiaxial fatigue damage model was derived under multilevel loading.

为了描述多轴比例与非比例加载下的疲劳损伤特性，结合多轴疲劳损伤的特点，建立了一种新的非线性多轴疲劳损伤累积模型，并推导给出了该疲劳损伤累积模型在多级加载条件下的递推公式。

Third, the stress-strain and damage parameters on multiaxial fatigue damage critical planes were analyzed. A new multiaxial fatigue damage parameter was presented. This parameter can not only describe multiaxial proportional and nonproportional loading, but also uniaxial loading.

第三，对多轴疲劳损伤临界面上的应力应变及损伤参量进行了分析，在此基础上提出了一种新的多轴疲劳损伤控制参量，该参量不仅能够描述多轴比例与非比例加载下的疲劳损伤，而且可以退化成单轴的形式。

Analysis of microstructure fracture surface showed that fracture surface was similar to uniaxial fracture surface under multiaxial proportional loading, and the mixed fracture surfaces were found under multiaxial nonproportional loading.

微观断口分析表明，多轴比例加载下的断口形貌与单轴疲劳情况相似；非比例加载下，则以混合断口特征出现。

As the material is deformed beyond the strain that elastic deformation persists, the stress is no longer proportional to strain, and permanent, nonrecoverable, or plastic deformation occurs.

当材料的形变超出弹性形变发生的范围，其应力将不再与应变成正比，永久的、不可回复的形变发生，即为塑性形变。

Oxygen was found to depress their fcc-sctransition temperature Tc from the normal value of 260K,as indicated by theminimum in the temperature-dependent permittivity ε′,and also enlarge the drop in ε′at the transition.The magnitudes of the downward shift in Tc and the drop in ε′were roughly proportional to the O2 occupance at octahedral lattice sites,as estimatedfrom the resonance heights distribution.

发现氧的存在降低了以介电常数ε'温度谱极小值为标志的有序无序相变温Tc(正常相变温度为260K)，并且增大了ε'在相变前后的变化幅度，Tc的下降值和ε'的变化量Δε'近似比例于八面体位置氧的占据率，氧的占据率可以从核磁共振峰高的分布获得。

The level of β-tp was in direct proportional to the proliferation of cell in the oligodendroglioma cell lines (SHG-44, U-251, BT-325), but not in the non-oligodendroglioma cell lines (oophroma, prostate-carcinoma and neuro-oocyte).

但在非胶质瘤细胞株，如卵巢癌细胞，神经母细胞瘤细胞及前列腺癌细胞株等，β-tp的浓度与细胞增殖的趋势相反。
