从历史运动中抽取出来,历史规律是一个独立完整的逻辑体系,但在历史运动中,历史规律的逻辑体系要随着历史的具体时空展开而展开,所以,其制约性不会像传统的"可能性空间"说那样在任何时期都会"永恒在场"。尽管历史... 从历史运动中抽取出来,历史规律是一个独立完整的逻辑体系,但在历史运动中,历史规律的逻辑体系要随着历史的具体时空展开而展开,所以,其制约性不会像传统的"可能性空间"说那样在任何时期都会"永恒在场"。尽管历史规律贯穿历史进程始终,但只有当历史运动超越了历史规律允许的"空间"范围,历史规律制约性才会"出场",给予必要的"纠偏",使之不致成为历史规律贯彻下去的对立面。所以,历史规律一般地是以人们的活动对它的偏离作为实现的形式。 展开更多

Aluminum laminate is one kind of the rigidizable composite materials and plays an important role in construction of the inflatable space structure(ISS),which has potential application in space in the future.But the study of the predecessors mainly focuses on the research of the mechanical behavior in the room temperature,for this reason,mechanical properties of the aluminum laminate in low-high temperature have been studied in this paper.The failure mechanism of the aluminum laminate is also analyzed in the microscopic view by JCXA-T33 electron probe.The results show uhat the temperature has significant influence on the strength and Young's modulus of the aluminum laminate.With the increase of temperature,both the strength and Young's modulus of the aluminum laminate decrease.A model between Young's modulus of the aluminum laminate and temperatures is obtained by using Arrhenius equation.The predicted values by the model agree well with the experiment values. 展开更多

This paper mainly concerns the mathematical justification of the asymptotic limit of the GrossPitaevskii equation with general initial data in the natural energy space over the whole space. We give a rigorous proof of the convergence of the velocity fields defined through the solutions of the Gross-Pitaevskii equation to the strong solution of the incompressible Euler equations. Furthermore, we also obtain the rates of the convergence. 展开更多
