Through the analysis of the results of the compaction test, the key factors in the recycled material compaction test are unveiled.
Introduction Compaction ratio is used to control and evaluate construction quality of the base course in highway engineering.
Tests are conducted according to T0804-1994 from Test Methods of Materials Stabilized with Inorganic Binders for Highway Engineering (JTG E51-09).

Py-GC-MS Analysis on Biomedical Materials from Extractives of Moso bamboo for Biomedical Engineering MA Qing-zhia, WU Feng-juan, ZHANG Dang-quan, PENG Wan-xi Central South University of Forestry and Technology, City Changsha, P.R.
China ae-mail: pengwanxi@163.com Key words: Py-GC-MS; Biomedical materials; Extractives; Moso bamboo; Biomedical Engineering Abstract.
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 .

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.

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.

Thermal Stress Performance Analysis for a New External Wall Insulation System Jianguang Li College of Civil Engineering, Zhengzhou University, Zhengzhou, Henan, 450001, China lijian7553@163.com Keywords: Small frame, Shear key, Thermal stress, Crack.
In this paper, two models are taken as subjects, one being a small frame exterior composite insulation system with the shear key, the other being the system without the shear key.
Model1: W1-XKTP facing layer without shear key.
The thermal physical properties of the material can be seen in [2,3].
First, in this paper, it is assumed that the heat transfer of materials is passed only by heat conduction without considering radiation heat transfer of the 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.

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.

According to the research content, the research object is defined as the experts and scholars and researchers that study or work in the engineering project management.
The project, the owner party, construction side, the third side, materials and equipments and other objectives are all potential of the variables in the structural model.
We can help owner to communicate with the various project participants, to reduce engineering change as far as possible and strengthen the management of the construction site.
Materials and third party belong to the secondary factors have a bigger impact.
