Introduction Nickel-based superalloys are a group of materials, commonly used for high temperature application, in which high strength, good corrosion resistance and excellent fatigue resistance are needed.
Vitrified CBN grinding wheel is one of the most promising abrasive tools for its outstanding properties, such as high material removal rates, high heat resistance, low total cost and so on[3].

However, there is a common misunderstanding on the environmental issue, which goes like “the environmental issue is merely an issue of natural science and has little to do with social science”.
In fact, more and more social science scholars overseas are doing research on environmental protection and making their prescriptions now.
From the insight of political science, the democratic pursuit of sustainable environmental development is mainly focused on the environmental public participation.
The Democratic Pursuit of Sustainable Environmental Development: An Interpretation from the Legal Perspective From the beginning of 20th century on, the modern civilization has achieved unprecedented material and technological success.
