    摘要： A power supply apparatus for a radio frequency power amplifier (RFPA) is provided, where the output end of a voltage controlled voltage source (VCVS) and the output ends of N current controlled current sources (CCCSs) are coupled in parallel to supply power to the RFPA. The apparatus further includes an nth sampling unit, configured to sample the sum of the output currents of the first (n−1) CCCSs and the VCVS to obtain an nth sampling signal; and an nth filtering unit, configured to filter the nth sampling signal according to a predefined nth passband and output the filtered nth sampling signal to an nth CCCS, thus controlling the output current of the nth CCCS. The nth passband is lower than an (n−1)th passband. The switching frequency of the nth CCCS is higher than the switching frequency of an (n−1)th CCCS. N is an integer greater than or equal to 2, and n is a positive integer smaller than or equal to N.

    摘要： The present invention discloses recognizing methods of flaky or blocky prohibited articles, explosives or drugs. Specifically, the method for recognizing flaky prohibited articles, explosives or drugs comprises steps of: (1) reading in tomogram data of an object to be inspected for one tomogram; (2) pre-processing the tomogram data; (3) splitting the pre-processed tomogram data into a plurality of regions that have similar physical properties; (4) analyzing whether each of the split regions is a flaky region; (5) determining whether the flaky region recognized in the current tomogram can be merged with the flaky region detected from the previous tomogram, so as to form a flaky target; (6) determining whether each detected flaky target is complete or finished; (7) repeating steps (1)-(6) and processing each tomogram data layer by layer, until all of the tomogram data have been processed.
