Case hardening steels are a group of high quality structural steels, which are mainly used in gear systems and driving elements in the automotive, aerospace and general engineering industries.
Introduction Case hardening steels are a group of high quality structural steels, which are mainly used in gear systems and driving elements in the automotive, aerospace and general engineering industries.
The chosen alloying concept - containing Al and Nb with only traces of Ti - can be carried forward without any risk to the current manufacturing process of engineering parts which are designated for high temperature carburising up to 1050°C.

Life-Cycle Low-Carbon Neighborhood: A Genetic Perspective in China Guochao Zhao1,a*, Xiaoming Wang2,b and Xiaokang Li3,c School of Civil Engineering and Mechanics, Huazhong University of Science and Technology, Wuhan 430074, China.
The World Economic Forum’s Global Risks Report 2016 has considered the failure of climate change mitigation and adaptation as the greatest potential risk of 2016.
S. (2005) first advances the concept of building energy gene and constructs the building energy gene theory, which provides a scientific method to accurately grasp the variation law of building energy consumption.
Based on the concept above we regard low-carbon neighborhood as a comprehensive trait which contain the following six traits: low-carbon layout planning, low-carbon building, low-carbon traffic, low-carbon environment, low-carbon municipal engineering and low-carbon construction management while each trait could also be divide into several traits which was shown in the Table 1.
Then we made a classification of low-carbon traits and classified them into following six traits: low-carbon layout planning, low-carbon building, low-carbon traffic, low-carbon environment, low-carbon municipal engineering and low-carbon construction management.

Meanwhile,integrate specific engineering practice case--XX Roads Comprehensive Renovation Project, do further research on the engineering cost estimation system of knowledge management applications based on case technology, and achieve knowledge reuse and innovation, as well as the shared values of knowledge resources.
While project cost estimate has its knowledge-intensive features, how to make up for deficiencies of traditional knowledge management applications, improve the efficiency of knowledge reuse and achieve dynamic knowledge management application mode are the current engineering knowledge management research focus.
There are two kinds of search method primary search and advanced search through the effective combination of knowledge guide and adjacent strategy.
