Its viscosity was 141mPa·s,expansion rate was 400%～530%,compressive strength was 1.49MPa,and elongation was 150%～218%,its gel time could be adjust,and it had very good adaptability to water with various pH values,moreover it had excellent capability of water containing.
The results show that with the increasing of hardness of 45 steel,its wearing resistance increases considerably when hardness of abrasive(Ha) is higher than hardness of 45 steel(Hm),however,it varys very slowly for Ha
Illegal publishing activities not only destroy the publication management system,disturb regular market order of publications,but also mislead and deceive social masses,damage the legal interests of teachers and education staffs,disturb the regular education and teaching activities of schools,which are very harmful to society.
The remaining life formula of the neoteric architecture,whose core is damage parameter,is established,in which the feature of the neoteric architecture has been considered and the latest research achievements of structure's remaining life are referred. The formula which predicts the remaining life of the neoteric architecture quantatively is very convenient in the applied engineering.
