Hydroxyapatite (HA) is a bioactive material that can provide good osteointegration and rapid bonding with the adjacent hard tissue [2].
Ti–6Al–4V is also well known for their potential as superplastic materials for applications in different areas including the aerospace, transportation and biomedical fields.
Superplastic materials are polycrystalline solids which have the ability to undergo large strains prior to failure.

Nano-materials have been titled the most promising materials in 21 century by scientists.
In recent years, much attention has been paid to the applications of nano-materials in civil engineering, because nano-particles have many special properties such as huge specific surface area and high activity due to their small size.
Experiment Materials and mixture proportions The cement is P.O42.5.

Abstract.
While being stirred, the obtained colloidal mixture was aged at 55-60oC for 6 hrs and then was separated using a centrifuge at 8000 rpm to obtain wet solid material.
The wet solid material was washed with double distilled water several times until free of Cl- ions, indicated by visual observation using AgNO3 solution as a test reagent.
The resulting solid material was dried at 100oC for 12 hrs followed by heat treatment at 450oC for 4 hrs under open air in a tube box muffle furnace to produce CZT-ONC photocatalyst.

Pumping equipment is extremely diverse varying in types, sizes, and materials of the construction.
The conceptual description of the pump is presented as follows: The pump chamber consists of a hollow cylinder of nonmagnetic material (e.g. plastic) with at both ends an inlet and an outlet (H shape), all equipped with a check valve (i.e. four in the total) that operates in the corresponding direction.

The main solution to prevent the vibration of embroidery machine beam is to analyze its vibration characteristics [2] and then increase the beam weight (such as filling the beam with material ) or shorten the beam[3] etc. , for example, Anderson has succeeded in reducing the vibration of the beam effectively by making use of new materials to fill the beam.

Abstract.
We use micro-teaching laboratory, multimedia teaching equipment, video generation and capture instruments, digital projectors and multimedia computers to build digital micro lab teaching system with the function like network, multimedia, storage and transmission of audio and video, and other technologies, which provides the material conditions for modern training of the teaching skills.
It provides important technical support for interscholastic teaching; it also provides lots of reference materials for analysis and self-analysis of the teachers’ teaching processes and philosophy, which are accurate and authentic.

Simulation design of base station enclosing structure's heat transfer model
Base station enclosing structure's heat transfer model
Base station enclosing structure's heat transfer is mainly realized in convection and radiation heat transfer forms, and also is the most complex in the heat transfer calculation because it is affected by base station enclosing structure's characteristics, building material's heat capacity, heat transfer and thermal insulation properties, delay, attenuation, and the radiation and reflection from surface materials, and also the external environmental factors such as temperature and humidity, wind speed, solar radiation intensity, all kinds of heat reflection,, and heat island effect of base station.
