Introduction Nickel-based single crystal superalloys are predominately used as materials for turbine blades in aero-engines because of their excellent mechanical properties at elevated temperatures.
A three-dimensional cellular automaton (CA) model coupled with finite-element (FE) thermal transfer calculation commercial software ProCAST were used to solve for the heat transfer using the conservation of energy with temperature/time boundary conditions and temperature dependent material properties [9]: The transient nonlinear heat conduction equation is as follows: ( / )( / ) [ ] ( ) 0 H T T t K T S r ρδ δ δ δ −∇ ∇ − = (1) where ρ=ρ0 f (T), constant or temperature-dependent density, T is temperature, t is time, K=K0 f (T), constant or temperature-dependent conductivity, S(r) is volumetric heat source and H is enthalpy of solidification, a function of temperature, which encompasses the effects of specific heat and latent heat. it can be expressed as: 0( ) [1 ( )] T p s H T C dT L f T = + −∫

Among studied molecules the λhole values of Si(TFP)Cl2 is close to its λelectron’s, therefore Si(TFP)Cl2 should be promising candidates of red light-emitting materials with high efficiency.
Furthermore, the λelectron values of studied compounds are closed to that of tris(8-hydroxyquinoline) aluminum (Alq3)[23] which is conventional electron transport materials.
This indicates they could be good electron transport materials from the standpoint of λ.
Thus they could be good hole transport material from analyze of λ.
This present study dedicates to find out how the ruffled conformational distortions of the porphyrin ring affect the charge injection and transfer ability, and hope to broaden the application of distorted porphyrin in different fields such as light harvesting materials and the photodynamic therapy.

Individual metal materials behave differently under the action of atmospheric corrosion.

Introduction Concrete mixer is a major component of concrete mixing equipment, by whose function will be mixed the concrete mixture having a certain uniformity and workability with a certain percentage of each component qualified materials,this is the beginning of the formation of structure in concrete.Twin-shaft compulsory mixer is commonly used in road concrete in highway,which there are many type of concrete mixer.The shearing action by mixing blades imposed on the material, squeezing and turning movement in compulsory mixer,which achieve a reasonable way of the material flow.
名词 1. coordinate （2） where, —the constant stirring sp eed；—the average time of particles materials in different interval；显示对应的拉丁字符的拼音 字典—the number of intervals.
Research on mixing time mixing time The time which all materials are put into the mixer until the material discharged are called the pure mixing time, also known as mixing time.

Circular agriculture is to realize the materials and energy to be multi-level used through the design and management of agricultural eco-economic system, and to achieve the industry goal of maximum utilization, the lowest investment, renewable resource efficient recycling,pests and pollution control in the agricultural system[1].Using the thought of sustainable development ,methods of ecological engineering, technology and innovation, it could improve the multistage material energy utilization and looking for more circular nods[2].
Some countries control the price of global bio-energy raw materials [10], and manipulate the international raw materials market.
It not only increases the food production, but also provides rich raw materials for bio-energy development.
There are plenty of trees and flowers for urban greening and a large number of biomass materials.
If the materials developed reasonably, abundant raw materials and fertilizers would be provided for the development of bio-energy and circular agriculture, and that will have a wide prospect for development.

Introduction Wood has a number of excellent properties as a building material: it has a high strength to weight ratio, it is a good thermal insulator, it can be shaped and connected to form larger structures and it is one of the most sustainable and environmentally friendly materials.
This made many engineers and a significant part of the public sceptical about the use of wood.

The XREC is not the bulk elastic modulus for the material, but instead, describes the anisotropic nature of elasticity in materials.
Stress (sf) may be calculated using equation 1 which is derived from Hooke’s law for isotropic, homogeneous materials [7].

Analysis of the problem of Construction Enterprise’s Human Resources Structure Optimization Ying Ou College of Civil engineering, Shenzhen University, Shenzhen, China szuce@szu.edu.cn Key word : Construction enterprise human resources structure optimization Abstract: The human resources structure situation and its the subject problems of the Chinese construction enterprises were analyzed, The reasons were studied from the aspect of the planned economy system, human affairs system, internal management system and enterprise human capital investment.
Shortages of engineering and technical persons, combined persons, skill workers are more prominent.According to recent data published by China Statistical Yearbook[2], The share of construction professionals, engineering and technical staff and enterprise management is lower than the national average about 3-5%.
Personnel who are familiar with new technology, new equipment, new materials, new technology and technical are particularly less.Structural shortage of talent is evident, the actual number of talent have failed to meet actual enterprise’s needs.
The construction industry is a huge engineering system, the kind of work is various, the work procedure is complex, the high or low level technology personnel are needed at the same time, the necessary persons include have project managers, engineers, technicians, construction workers, security staff, quality inspector, machine operator, surveying engineering, bricklayer, carpenter, electrician, fitter, plumber, painters, welders, riveter and so on, which require a large number of skilled workers.
