It was shown that TAPP and its metalloporphyrin complexes all had good photoconductivity. The surface photovoltage response in tensity of Soret band and Q band were enhanced with an external positive electric field and weakened with a negative electric field, and possessed the characteristic of p-type semiconductor.

并研究了这些卟啉化合物在不同外加电场条件下的表面光电压谱，结果表明，TAPP及其金属配合物都具有良好的光电性能，且其Soret带与Q带的光伏响应强度随外加正电场光伏响应强度的增加而增强，随外加负电场光伏响应强度的增加而减弱，具有P-型半导体的特征。

Floor heating systems have been used since ancient times due to their advantages over other heating systems. Previous studies are mainly on the floor heating systems using hot water. There is insufficient study, to the author's knowledge, about floor heating systems using electric heating cords. In the thesis, the heat-transfer characteristics and comfort for the floor heating system and ceiling panel heating system using electric heating cords were investigated.
