  1. Nanosized lead titanate ( pt ) and lead titanate doped with calcium and lanthanum ( pclt ) powder obtained by the sol - gel method was added into vinylidene fluoride - trifluoroemylene [ p ( vdf - trfe ) ] to form nanocomposite to be used as the sensing film of the pyroelectric detector. the experiment results show that after mixing in 0. 16 volume fraction of pclt powder, the pyroelectric coefficient of pttp ( vdf - trfe ) composite film was about 37 % higher than that of the pure p ( vdf - trfe ) film prepared under the same condition, and the voltage figure - of - merit of pt / p ( vdf - trfe ) composite film was about 22. 4 % higher

    用溶膠-凝膠法制備了鈦酸鉛( pt )和摻鈣鈦酸鑭鉛( pclt )納米粉粒,與聚偏氟乙烯-三氟乙烯( p ( vdf - trfe )均勻復合,由於16的摻鈣鈦酸鑭鉛納米陶瓷粉粒的摻入,使得pclt / p ( vdf - trfe )復合膜的熱釋電系數值提高了約37 ,探測優值提高了約22 . 4 。
  2. This method takes the second generation wavelet transformation as a base, using the interrelation between transformation sample and adjacent sample to detect partial feature of the signal, and according to the magnitude of related coefficient to define the optimal pre detector and re - newer of every sample in every dimension, so as to let the wavelet be able to suit fairly the partial feature of the signal
