This paper makes a detailed analysis on application and role of time and space thinking in knowledge system and learning method of civil engineering and put forward time and space thinking to be similar with philosophical view of time and space. Time and space thinking is a scientific method, therefore, it is suggested to make students active in having such idea and strengthen students＇ understanding on time and space thinking, which will helping students recognize knowledge system and stimulate innovative abilities.展开更多

There are differences between TCM and chemical drugs. For TCM, the multiple components in vivo are possibly to be detected; the number of components is relatively restricted; they could represent the therapeutic effect of the parent recipe; the concentrations and pharmacokinetics （PK） could affected by the combination of traditional medicines in recipe; the effects of new bioactive compounds （metabolites） related with those of their recipe; and the PK can be affected by body state in TCM treatment significantly. Therefore, the difficulty and challenge are far greater in PK study of TCMs than the chemical drugs.展开更多
