4-aminoacridone was efficiently synthesized using an optimized method and condensed with a variety of different aldehydes to give the corresponding Schiff bases, 1a–k. The antiproliferative activities of these compounds were measured against several human cancer cell lines in vitro, including A549, HeLa, SGC-7901, and Raji cells. The results of these(More)
To reduce the spectrum leakage that comes with signal processing of single-speed sampling, the computer simulation of signal processing has been realized with double-speed sampling by using LabVIEW. According to the specterum analysis of these two sampling method, it show that double-speed sampling method decreases time-bias accumulation of sampling period(More)
