high voltage的音標是[?ha? ?v??nt]，基本翻譯是高電壓。速記技巧可以是將每個音節拆分后分別記憶，如“ha?”可以聯想為“嗨”，-“vo?”可以聯想為動詞“volunteer”（志愿者），-“n”為名詞后綴。

High voltage:

詞源：High voltage一詞來源于英語，其詞根voltage源自拉丁語的“vellum”，意為“木板”，引申為“電板”或“電容器”。voltage一詞由“volta”和“tage”兩部分組成，“volta”指的是電池，“tage”意為“電壓”，因此voltage整體上可以理解為電池產生的電壓。

變化形式：在英語中，high voltage通常以單數形式出現，但在描述高電壓時，也可以使用復數形式。
