无序有序变化

Theobserved strain is 10~2 times as local point strain at the same observed stress.This indicates that macroscopical symmetrical rock is quasi-brittle materialwith microcosmic heterogeneousness and its macroscopical mechanicalbehavior is the results of reciprocity and magnification between microcosmiccharacteristic, not simple sum.(4) The degree of irregularity of strain increases with the number of cycle.But degree of irregularity of transverse strain fluctuates larger at the samecycle. Moreover degree of irregularity of transverse strain is larger than that ofaxial strain. This shows that deformation and failure of rock is process ofevolvement of small crack. Small crack evolves from even and out-of-orderstatus to heterogeneous and ordinal status.(5) Ultrasonic speed decreases with the number of cycle. The decreasecourse is such: Firstly, ultrasonic speed fluctuates in a steady scope in somecycles; And then ultrasonic speed quickly decreases to a certain more smallvalue; Afterwards in succedent cycles, ultrasonic speed fluctuates about thevalue. That is to say, ultrasonic speed fluctuates and decreases at intervals ofcycles. In deformation process of rock, quantitative change and qualitativechange of its small crack evolvement carry through crosswise.(6) Strength and modulus of rock decrease with exponential function asscale of specimens increases.

同一表观应力下，局部点应变与表观应变相差可达2个数量级，表明宏观上均匀的岩石是具有细观特征的准脆性材料，其宏观力学行为是细观特征相互作用、放大的综合结果，而不是简单的叠加；(4)岩样轴向应变不均匀程度和横向应变不均匀程度随循环次数的增加渐进增大，但是在同一个循环内，横向应变离散系数随应力的变化波动较大，且同一循环级别下，横向应变不均匀程度大于轴向应变不均匀程度，表明岩石内部微裂纹的演化是岩石变形破坏的本质特征，这一演化表现为微裂纹从均匀无序分布逐渐向非均匀有序发展；(5)随循环次数的增加，所有岩样内部超声波速会出现衰减，衰减过程表现为在某几次循环内超声波速在某一相对范围内波动，然后急剧减小到某一较小值，在随后的循环内，超声波速又会保持在这一较小值附近波动，即超声波速表现为波动和急剧减小间隔形式衰减，表明从宏观看来平稳的岩石变形过程，内部结构演化过程(微裂纹发展及其相互作用)却表现为均匀量变和突发质变不断交叉进行的现象；(6)岩石强度和弹性模量随尺度增大呈指数函数规律减小。

It is the change from an ordered arrangement to a disordered arrangement which is the source of the irreversibility.

从有序的排列到无序排列的变化是不可逆性的起源。

There is a peak of voltage noise driven by the current in the vortex glass state.

通过分析磁场激发产生的涡旋度 Ne 及低频电压噪声 S 0的变化特性，得到如下结论：在无序超导体中固定温度不变，随着磁场的减弱涡旋液态经过准有序的布拉格相，涡旋玻璃相重新进入到低磁场下的钉扎稀磁液相。

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。
