一緻 is always used within a context which is very small (eg.
front and back of a novel / show / art / person's character).eg.
front part of the novel talks about main character call 阿發
(Ah-Huat), as you read onwards the name of the character changes to
阿明 (Ah-Beng), not consistent, 不一緻。 Sometimes watch dramas
also can see the actresses and actors, during the same scene,
clothing and hairstyles change drastically --because shoot on
different day then recombine -- also is 不一緻。)
統一 when used as a noun in Mandarin Chinese is "standard",
when used as a verb in Mandarin Chinese is "unify",
therefore usage-wise some meaning overlaps into English
"standard"
規範 - as per explained above
Tks for the clarification.
