1. 制服
    A uniform is a special set of clothes which some people, for example soldiers or the police, wear to work in and which some children wear at school.

    e.g. The town police wear dark blue uniforms and flat caps...
           鎮(zhèn)上的警察穿著深藍(lán)色制服，戴著鴨舌帽。
    e.g. Philippe was in uniform, wearing a pistol holster on his belt...
           菲利普身著制服，腰帶上別著手槍皮套。

2. （某一群體的）特種服式
    You can refer to the particular style of clothing which a group of people wear to show they belong to a group or a movement as their uniform.

    e.g. Mark's is the uniform of the young male traveller — green Army trousers, T-shirt and shirt.
           馬克一身年輕男性旅行者的典型行頭——綠軍褲、T恤外加襯衫。

3. （同一物）始終如一的，均勻的，劃一的
    If something is uniform, it does not vary, but is even and regular throughout.

    e.g. Chips should be cut into uniform size and thickness...
           土豆條要切得大小厚薄均勻。
    e.g. All flowing water, though it appears to be uniform, is actually divided into extensive inner surfaces, or layers, moving against one another...
           所有流動(dòng)的水看似一成不變，但實(shí)際上內(nèi)部分成許多廣延的面，或者說層，彼此逆向移動(dòng)。

4. （不同物）全都相同的，一律的，清一色的
    If you describe a number of things as uniform, you mean that they are all the same.

    e.g. Along each wall stretched uniform green metal filing cabinets...
           每面墻邊都一溜擺著相同的綠色金屬檔案柜。
    e.g. Shrimp are raised in long uniform ponds, frozen in the nearby packing plant and shipped north.
           蝦放養(yǎng)在清一色的長(zhǎng)池子里，再送到附近的包裝車間冷凍，最后用船運(yùn)往北方。
