SI Unit 国际标准单位 Base units can be combined to derive units of measurement for other quantities. In addition to the twodimensionlessderived unitsradian(rad) andsteradian(sr), 20 other derived units have special names. Named units derived fromSIbase units Other common units, such as thelitre...
摘要: The two new units adopted at the 15th General Conference of Weights and Measures (May, 1975) are discussed. These are the becquerel, the unit of activity, and the gray, the unit of absorbed dose关键词: General or Review/ dosimetry radioactivity units (measurement)/ SI units ionizing ...
