The method is based on an idealized structural unit method.

In order to accurately evaluate the load capacity of large LNG carriers,comparative study was conducted using representative analytic method,simplified method,idealized structural unit method and nonlinear finite element method.

In this paper, several important physical properties parameters of polymers, such as specific volume Vp, solubility parameter δ, glass transition temperature Tg and molecular weight between interchain entanglements Mc, have been determined by structure unit contribution method using microcomputer.

In this paper,the three stress distribution cases of Xiluodu double curvature arch dam without outlets,with 8 upper outlets +7 bottom outlets and with 2 upper outlets +6 middle outlets +7 bottom outlets are analyzed with substructure element method.

The practical measure such as "unit structure teaching method" is taken to enable students to participate in all aspects of the teaching experiment,which changes the simple and traditional "teaching-accepting" relationship between teachers and students,enhances communication between teachers and students and stimulates students\' enthusiasm and initiative.

Study on ideal structure and manufacturing method of hot forging die material

Based on the analysis of the typical forests structure, the gap characters of virgin tropical montane rainforests and guided by the theory of NearNature Forest Management, the indicators and standards of ideal structure of montane rainforest in Bawangling of Hainan Province were put forward.
