【Abstract】 The methods of design, calculation and linear process of multi point source are introduced. The multi point source radiative level has been applied to some works. The accuracy of the radiative level are 2.5%. The multi point source is made rather simply and cost cheaply than rod shapped source. So that, this kind of radiative level may be developed fast.更多还原
