Residual stress is one of internal characteristics of WC coating by thermal spraying, the reason is that coating-substrate materials have bigger temperature grads and different physical performances [3].
In Fig.4, when the difference of temperature is same, thermal stress produced by heat has mainly relation with thermal expansion coefficient difference of coating-subatrate materials.

Due to the environmental problems resulting from the production of cement, created the demand to replace the cement by industrial waste materials, Fly ash (FA) is the waste material having pozzolonic properties, also it is cost-effective and eco-friendly material.
Materials High Calcium fly ash and Aggregates.
Waste materials such as HCF are used as binding materials, M-sand is used as fine aggregate, Sodium hydroxide (SH) and Sodium silicates (SS) are used as alkaline solutions, with different AL to HCF such as 0.45, 0.55, 0.6 and 0.65 under ambient curing.

Although some libraries have a very large collection of books, the inaccurate grasping of the university teachers and students’ demands for materials document has led that the introduction of literature can’t solve readers’ problems and the materials that can’t be used and are rarely used have caused the waste of resources; fourth, the insufficient management of libraries does not protect the collection of books well.
Modern libraries should achieve the literature information sharing with multi-level, multi-channel and multi-dimension, actively control the information demands of readers, and take various measures and approaches to meet readers’ needs of book materials and information resources to the maximum extent, improve the utilization rate of books, and fully play the biggest benefits of books.

Introduction The main feature of intelligent materials is their ability to react to changes of external conditions and operation environment and to reform themselves and change their mechanical parameters [1].
Biological materials belong to this type of materials, including bone tissues.
Artificial biomaterials used for replacement of bone tissue with the consideration of individual features of the patient also belong to intelligent materials [1].
