DESCRIPTION:Solar white light flares\, which are solar flares with visible
  continuum enhancements\, first observed in 1859. They have been observed 
 in energetic flares with small area of brightening (~arcsec)\, weak intens
 ity enhancement (<10%)\, and had some different characteristics of structu
 res and spectra at the same time. In spite of its long history\, how and w
 here they are formed are still under discussion. The main cause of white l
 ight flares is said to be accelerated electrons which are precipitated to 
 the solar surface\, and revealing the formation mechanism of white light f
 lare may tell us some clues for one of the biggest problems in Solar Physi
 cs\; "Particle acceleration in solar flare". I will present my recent rese
 arch on solar white light flares by a spectroscopic and a high cadence ima
 ging ways\, with some speculations on the formation mechanisms of the whit
 e light emissions.
