In order to characterize the vertical variation of abundance and community composition of ammonia-oxidizing archaea (AOA) and ammonia-oxidizing bacteria (AOB) in sediments of a eutrophic lake, Lake Taihu, molecular techniques including real-time PCR, clone library, and sequencing were carried out in this study. Abundances of archaeal amoA gene (ranged from(More)
Either under normal condition or fault condition, the characteristics of the voltage and current of half wavelength transmission line are different from the characteristics of the ordinary short line, for its transmission distance is much longer the voltage level is much higher than the ordinary transmission line. Its distributed-parameter characteristics(More)
