二二三根据二二三的化学結構式((?)CHCCl_3)可以看出其中含有二个氯,二个苯及三氯乙烷,故簡称为“二二三”。按其拉丁名为Dichloro—Diphenyl—Trichloroethane,第一个字为二氯,第二个字为二苯,第三个字为三氯乙烷。簡写皆用其第一字母,故也簡称为“D.D.T.”。現常譯作“滴滴涕”。 Two two three According to the chemical structure of 233 ((?) CHCCl_3) It can be seen that it contains two chlorine, two benzene and trichloroethane, it is abbreviated as “two two three.” According to its Latin name Dichloro-Diphenyl-Trichloroethane, the first word is dichloride, the second word is diphenyl, the third word is trichloroethane. The abbreviations all use their first letters, so they are also called “D.D.T.” for short. Often translated as “DDT.”
