摘　　要：This paper introduces the design and development of a new computerized data acquisition system for the coal fired magnetohydrodynamical (MHD) electrical power generation experiments. Compared to the previous system, it has a higher sampling rate and an improved simultaneity performance. It also improves the data collection method and sensor design for the measurement of Faraday voltages and Faraday currents. The system has been successfully used in many regular MHD generator tests. It provides an excellent base for the future research and development of the Coal fired MHD electrical power generation.0　ＩｎｔｒｏｄｕｃｔｉｏｎＴｈｅｎｅｗｌｙｄｅｖｅｌｏｐｅｄｃｏｍｐｕｔｅｒｉｚｅｄｄａｔａａｃｑｕｉｓｉｔｉｏｎｓｙｓｔｅｍｉｓｕｓｅｄｆｏｒｔｈｅｃｏａｌｆｉｒｅｄＭＨＤｅｌｅｃｔｒｉｃａｌｐｏｗｅｒｇｅｎｅｒａｔｉｏｎｅｘｐｅｒｉｍｅｎｔｓ,ｗ...
