查询词典 radiation

The experimental results indicate that the new solar simulator can effectively control radiation intension and stability. When the standard light intension is 1000 W/m^2, the radiation uniformity is 2.5% and the radiation stability is less than 1% in a diameter of 250 mm, which has greatly improved the performance of the solar simulator.
