Using characteristic description to define High-Tech fields is mainly expressed by the summary of design thought, material application,structure treatment and construction properteis. In the 1950s, Early High-Tech school focused mostly on technology application and standardization ; in the 1970s, they emphasized industrial techinic, mainly using industrialized steal profil, glass, plastic, metal sheet and tightwire of mass production to display industry succes. In 1990s, late High-Tech school proposes durable developpement concept, to pay attention to tract, to bring importat emation factor into conception, to improve energy using rate, to protect ecological environment, and to creat comfortable environment.
