We compare the present schemes with the explicit multistep exponential time differecing and Adams Bashforth-Moulton method. The numerical results show that the schemes are more accurate and more efficient than Adams predictor-corrector method. The exponential time differencing method has been developed and perfected by the present studies.展开更多
Measuring radiometric quantities of light can be done by way of alge-braic insert.And also a function of radiomeertric quantities of light source is presented.The spectrum dispersion law of light source is given.
