True-Time-Delay (TTD) is the main technology for phased array antennas (PAAs) beamforming applications.
实时延(TTD)技术是现代相控阵天线(PAAs)中的关键技术。
Microbial degradation by acclimated activated sludge was investigated to characterize biodegradability of landfill leachate.
利用驯化活性污泥法对组分复杂的垃圾渗滤液进行有机物降解实验。
The acclimated activated sludge could degrade organic substa nces normally when the concentration of Na 2 SO 4 was less than 20000mg /L in the wastew ater.
在有菌种存在的好氧系统中,采用驯化活性污泥的方法处理高含盐量有机废水。
