napalmyoudaoicibaDictYouDict[napalm 词源字典]
napalm: [20] Napalm, a jelly-like substance, is made by thickening petrol with the aluminium salts of naphthenic acid and palmitic acid, and the term napalm was coined in the early 1940s from the first syllables of naphthenic and palmitic (the former is from naphtha [16], ultimately of Greek origin, the latter from Latin palma (see PALM), because the acid is obtained from palm oil). It was used in World War II, but it was the Korean War that really brought it to public attention, and it is from then that the use of napalm as a verb dates.
