心血管系統病癥如中風偏癱半身不遂呼吸系統病癥如氣管炎肺炎哮喘支氣管擴張等腦部退化病癥如柏金遜癥手腳活動失控等物理治療與藥物治療,里應外合,令復原事半功倍。The maximal power outputs of 37. 0 mw / cm2 and 30. 0 mw / cm2 for the p - and n - type laminated materials respectively at the temperature difference 490 have been experimentally obtained, which are about 2. 5 and 3. 0 times those of - fesi2. chemical analyses show that the interface failure between the bridge alloy and the semiconductor bi2te3 results mainly from the eutectic mixtures with low melting point and brittle compounds formed during welding and long time annealing at 190. it is found that the electrical properties of a laminated structure are mainly controlled by the wettability of the bridge alloy on the semiconductor surface
發現: 1 )疊層材料具有明顯優于均質材料的熱電性能,在490溫差下, p -型和n -型疊層材料的最大輸出功率分別達到37 . 0和30 . 0 ( mw / cm ~ 2 ) ,是同類型均質- fesi _ 2的2 . 5和3倍; 2 )在焊接過程和190長時間退火處理過程中,焊接過渡層合金和基體半導體(特別是bi _ 2te _ 3 )之間存在明顯的元素相互擴散,從而在過渡層中形成一些低熔點共晶體和脆性化合物,這是導致疊層材料破壞的主要原因; 3 )焊接過渡層合金與半導體基體之間的潤濕性是影響界面層電性能的主要因素。Two compounds with the purity higher than 95 % were obtained with this method
