The Simulation of Poly Reactors and chain-analyzing method in material engineering Dongmei Zhao 1,a, Xuepeng Liu 1,b 1Zhongshan Polytechnic, P.R.
One or a series of continuous stirred tank reactors (CSTR) is adopted in material engineering.
Introduction Chemical materials engineering process simulation system program structure includes chemical materials, materials program storage unit property calculation packets and material calculation method program storage, etc.
This paper argues that the reaction to a practical mathematical model of the precision allow it is reasonable to simplify, based on the P.J.F lory proposed reaction speed constant and molecular keys such activities irrelevant to the principle of functional groups (i.e., different molecular size the same functional groups have the same reaction ability, and place the molecular keys not long) and esterification condensation reaction of double and functional groups, model of the rate equation using secondary reaction.
Another kind is the structure, and method, this method to establish in liquid vb is the constituent atoms and key or groups and functional contribution value added and volume of the foundation.

Preparation and Characterization of Biodegradable β-TCP-based Composite Microspheres as Bone Tissue Engineering Scaffolds Qingfeng Zan, Chen Wang, Limin Dong, Rui Liu and Jiemo Tian Beijing Key Laboratory of Fine Ceramics, Institute of Nuclear and New Energy Technology, Tsinghua University, Beijing 100084, People's Republic of China Keywords: Tricalcium phosphate, Chitosan, Microspheres, Tissue engineering Abstract.
In vitro immersion experiments were carried out to evaluate the degradability of the microspheres, and the results demonstrated that the chitosan/β-TCP composite microspheres were potential materials as tissue engineering scaffolds for bone repair.
β-TCP ceramics have been used as bone-filling materials in orthopedic surgery.

Introduction Moso bamboo (Phyllostachys pubescens), which is a superior resources, is often used as the raw materials of furniture, doors, flooring, windows and beams, and so on[1].
Materials and Methods Materials.
So the benzene-alcohol extractives of Moso bamboo could be used for biomedical engineering .

As the production progresses, stored materials deplete constantly hence the materials need to be replenished when storage volume reaches a specific amount so that the next production phrase can operate normally.
Chang Yi [4]has advanced the Economic Order Quantity model by researching the problems regarding engineering materials inventory management and using that model to identify the minimum material storage volume.
He holds that the engineering material fee normally accounts for some 70% of the total project cost therefore material management plays an important part in the construction industry’s management.
It is an example applying storage method to address the storage problems of engineering materials.

It has a certain guiding significance to further improve the reform of engineering classroom teaching reform.
Firmly Grasping the Before Class - Class – after Class Three Links In the link of preparing lessons before the class, seriously studying teaching materials and excavating thinking materials deeply The teaching materials of engineering specialty courses have less tight deduction system than basic course materials, and it is much more difficult to follow the prescribed order in thinking activity teaching compared with the traditional knowledge teaching.
Teaching materials previously tell about the rectangular section flexural calculation, therefore, we can extent T shaped cross section bending calculation to the rectangle section, I-shaped, portal, inverted L shaped section or ribbed structure.
Emphasized the practical engineering of the key problems, and then guide the students’ image thinking, help students memory on the basis of understanding.

Introduction As the economic globalization is gradually improved, the competition of engineering machinery product markets is increasing day by day.
This module is composed of Solid Edge and the general machinery part three dimensional CAD system, which is mainly used to establish the parts and assembly of engineering machinery, and create the engineering drawings.
This module completes the processing technology design, using the engineering drawings created by Solid Edge.
Visible CAPP system based on Solid Edge platform.The original design method of technical chart is that engineering drawing is designed in the three dimensional CAD system, then imported into CAPP system of Auto CAD platform to complete the technical chart, meanwhile there is no direct relationship between engineering drawing and the technical chart.
Partial documents information is supplied for users in the homepage like Properties, Part Tree View, Bill of Materials.

Machinability Evaluation of Engineering Ceramics with Digraph Method L.J.
A new method is proposed for machinability comprehensive evaluation of engineering ceramic materials based on digraph theory.
At present, ceramic materials are applied extensively in various engineering areas, grinding is the widely machining way.
Machinability of four typical engineering ceramics were evaluated and machined.

Application Progress and Vision of Biocereamics Utilized in Bone Tissue Engineering Liu Yi a BME College, Tianjin Medical University, Tianjin, China a Pisces_cream@163.com; Anjian630712@sina.com Key words: Bioceramic, Bone tissue engineering, HA, CPC, BG, application Abstract: From human bones to animal bones, from stainless steel to plastic, researchers have tried numerous types of materials to apply in the bone replacement for human-beings.
But deal to their limitation on fatigue, stability, mechanical strength and many other properties, almost all those past materials were superseded by bioceramics today, which perform not only those advantages possessed by the old materials, but also hydrophilic, biocompatibility, thus ensured them a promising future in the region of bone tissue engineering.
Good biocompatibility of bioceramic materials made them perfect artificial synthesize scaffold material for bone tissue engineering.
