Though a series of modified Z-A model were developed, such as Samantaray’s [11] model, the underlying physical process and the composition of the material components are not considered.
The various obstacles in the material have a contribution to the dislocation mean free path of slip, thus, the dislocation mean free path which combined the distance between the second-phase particles, the distance between the grain size and the distance to other dislocation is given by Engberg [18]

Specific performance is in: it fully consider the needs of readers in general layout, landscape environment, function space, streamline organization, architectural modeling, even furniture, oddment and installation of equipment, has reflected on the reader's material and spiritual care in all aspects.
Usually, it symbolizes “reading makes progress”, “book is the ladder of social progress of mankind”, “book is the engineer of shaping human soul”, “book is the key to open the door of wisdom”, etc.
In the pursuit of "grandeur", some libraries arrange thousands of square meters "share space" in the hall, and cover with new material glass roof, hanging chandelier, occupy a few thousand cubic meter volume.
