thanks for all your concern and your answers...
by the way,I 'm a student who learn bio-pharmacy in English...so,I little bit difficult to me ...and the only reason why I speak English just want to practise my English.I'm sorry if I make you misunderstanding...

另:俺觉得,紫外线固然可怕,但也别自己吓唬自己嘛,要不,那些在依靠紫外线消毒的无菌室里工作的人,就都去见马克思了~

安好
