Another is the planning construction model, many of which are the emerging modern university city and the science and technology school like Japan Tsukuba University, the US University of Missouri and so on.
For example, through academic and professional character of the celebrity spots mark the landscape design, especially through the efforts of selected alumni in science and art of prominent statues, sketches and so on.
This can stimulate the students’ passion of studying hard and research, to encourage young kids to follow the footsteps of these great men, and climb the peak of science.
People have different needs at different levels, As the complexity of schools and students form a variety of material, cultural and sports life of the diversity of students, space requirements of the campus landscape also presents the change of different levels, different space and different scales.

Using the residue as raw materials, a kind of polyacrylamide with low molecular weight is synthesized, which can be used as paper reinforcing agent or emulsifier.
The main materials for AMPS production are isobutylene, acrylonitrile, and concentrated sulfuric acid[1], so that, except AMPS, there are mainly TBAA and acrylamide in the residue.
