查询词典 reciprocity theorem

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。

In the angle of macroscopic, it is because of the ecomomic development, the nomocracy factor, the right consciousness; In the angle of microscopic, it is because of the illegibility of right and the reciprocity of right.

民事权利冲突的发生，从宏观方面讲，是经济发展因素、法治因素与权利意识因素三项外部原因的共同作用；从微观方面讲，是权利边界的模糊性与权利的相互性两项内部原因所致。

Love class the student all is to come from what strand a family especially within the area to taste the student that learns to hold actor concurrently, after student enter a school, department of education of city, area allocates funds through the government, accept a society to donate, begin a side to help approach of reciprocity learning a knot tiredly, prevent a student learn cost of incidental expenses, book, school uniform cost, activity cost to wait.

The intersection and interpenetrate of life science and engineering science are the conspicuous character of recent development of science and tenology. Envoluation, as an important self-adapt method drawn from life phenomena, has been generally recongnized and widely applied to problem solving. But the current evolving models have a common deficiency: they can not well reflect that the evoluation of the system is in fact the co-evolution under numerous local reciprocity.

生命科学与工程科学的相互交叉、相互渗透和相互促进是近代科学技术发展的显著特点之一，进化行为作为从生命现象中抽取的重要的自适应机制已被人们普遍认识并得到了广泛的应用，然而现有的进化模型存在一个共同的不足——未能很好地反映出一个普遍存在的事实：多数情况下，整个系统复杂的自适应进化过程，事实上，是一个构成系统的众多子系统局部相互作用的协同进化过程。
