This study will try to seek the evidences of these specific molecules in the osteoinduction of CaP materials.
Materials and methods Porous hydroxyapatite/tricalcium phosphate (HA/TCP) ceramics were prepared in our laboratory.
All the materials required for the experiment were prepared before starting the RNA extraction to minimize RNA degradation.
Therefore, the implanted materials showed an inductive effect on osteoblasts differentiation.

When material is subjected to random dynamic loading, maximal values of response smaller than its strength appear repeatedly.
So the failure of material will occur when its damage accumulation reaches certain fatigue limit, which is called cumulative damage failure.
The failure model is suitable for many metallic and nonmetallic materials whose failures are induced by the fatigue subjected to loading repeatedly many cycles.

Our country in the real estate industry to invest a lot of manpower, material and financial resources, real estate valuation industry plays an important role in the development of real estate industry.
The necessity and feasibility of introducing GIS in real estate appraisal The Geographic Information System (GIS) is the product of computer and geographical information science combined, widely used in various fields, such as resource management, city planning, environmental management, facility management, etc..
The establishment of the real estate in the actual appraisal information system's goal is to let the real estate information and related social and economic factors as the research object, the integrated use of methods and means of information science, system science and computer science, And a real estate evaluation as the main goal of integrated regional information system.

Different materials need different steam explosion temperature and retention time, some scholars have put steam temperature and retention time of convergence as a parameter with the intensity of steam explosion, R0 [7] (as shown in Equation 1), each type of material has its own optimum temperature and time parameters in steam explosion pretreatment, so that different scholars made different conclusions [8,9], but they all have confirmed that the semi-cellulose, lignin and cellulose of biomass were effective separated by steam explosion, which greatly enhanced the subsequent hydrolysis and conversion rate of cellulose
Because the material deformation rate of speed is much smaller than the shock wave, shear has occurred many times, so that the fibers were separated purposely.
