本文利用新型陶瓷技術、集成電路技術和厚膜平面安裝電路技術，採用零力學滯后的陶瓷和陶瓷密封材料進行設計製造了一種非充液乾式的電容式壓力傳感器，該壓力傳感器由較厚的陶瓷基體和較薄的陶瓷膜片構成，中間形成一空氣介質腔，在基座和膜片之間內置同軸的雙電極，組成兩個電容，當膜片承受壓力時發生位移，使電容量產生變化，經後置處理電路直接轉換為可輸出的直流電壓信號。Based on results of a lot of practical investigations, academic researches and comparisons of situations of real estate industry in changsha with that in other cities, this paper analyzes the present situations and existing problems of changsha ' s real estate industry and points out that the competition of foreign enterprises, the low degree of openness in renting system, the inefficiency in management, the conflicts of administration and practice, the lack of legal consciousness for agent serv ices, the nonstandardization of real estate management companies and the distemperedness in supervisory systems pose the outside threats ; ill managerial system, low technical level, small scales of companies, few measures for financing and marketing, poor quality and high prices of products pose the inside problems
