A Study on Case-based Learning in Engineering Graduate Education Yingqing Wu1,a , Tingzhang Liu1,a, Shenjing Jie1,a 1 Shanghai University, 149 Yanchang Road, Shanghai University, Shanghai China azoer001@126.com Key words: Engineering Graduate Education; Teaching Mode; Case-based Learning Abstract.
The research ability of engineering students is a major guarantee for national scientific development.
There are several difficulties to carry out the course teaching for engineering students.
The engineering classroom course is designed in this paper using the case-based learning method.
During the 2nd to 5th weeks, teacher gives topics on basic theoretical knowledge and main skills of technology report and then each team begin to anatomize cases and analyze raw materials.

Strategies for Inherent Safety Design during Engineering Construction Xin Wang 1, a, Lijing Zhang 1,b and Xiaoyong Liu 2,c 1 Safety Engineering Department, Nanjing University of Technology, Nanjing 210009, China 2Jiangsu Academy of Safety Science and Technology, Nanjing 210042, China awangxin_88@126.com, bzhanglj@njut.edu.cn, cxyliu@mail.ustc.cn, Key words: Engineering Construction; Inherent Safety; Layers of Defense; Design Strategy; Design Stage Abstract.
The opportunity for the inherent safety during engineering construction was analyzed.
The main hazardous factors of construction may result from mechanical equipment, temporary power utilization, basic engineering, structure engineering, etc.
For the engineering construction, the wear of wires and ropes should be as the key question to consider.

Although composite materials mould has low manufacturing cost, and openning mould spents less time, but its thermal expansion coefficient is small, and it is easily damaged.
It is applicable to all kinds of hard or soft materials.
A quick method of mould surface design based on reverse engineering is proposed.

How to help them to walk freely and safely through visual engineering design is an important key.
When two or more source materials are combined, they are called a composite material.
They are often used as structural materials.
Material designs of composite materials are based on constants and loading conditions of source materials in terms of choosing the most suitable source materials and determining sizes and materials of elements [8][16].

However only those with the higher dimension precise and better surface quality can satisfy the needs for engineering.
In 1988, Professor Bifano put forward a new idea about ductile grinding of brittle materials, in which the in-feed rate was taken into accounts[8].
In 1996 Professor Malkin discussed the cutting force and microstructure during the study of lapping mechanism of engineering ceramics[11].
