‘Enhancement phenomena’ in light scattering were found at 1970s. It is an importance phenomenon for (especial inelastic) light scattering.Up to now, it had been expended a huge effort and funds in this phenomena studies, or for more best explain away these results during the past more ten years. Recently, it had been pushed on the new place by super-high enhancement(g is the enhanced factor ~10^14-15)phenomena,andfor this sort of problems, experimental results, must deal with by using new idea or scattering crosses section. There aredetails given a few of machines about facility-pole of Green’s function, polarization, nanoparticles,nanolens, quasiphase-matching, single-molecule and interface layer or the boundary etc., which are unable understanding during the past a few decade. Except fundamental knowledges of light scattering intensity have been presented, for the new fields should been given too, for their research in further in this talking.
