The fluorescence quenching of these emissive compounds in solution by halogen anions was studied carefully.
研究了它们在溶液中的荧光被卤素离子猝灭的问题。

A class degenerate quasilinear parabolic systems is considered. The local existence is proved. In some conditions the solution quench in a finite time. And an estimate of quenching time is given.
Heat treatment methods, such as solid solution and quenching, have greatly enhanced its mechanical strength, which also leave a large internal residual stress in it.
