（单词翻译:单击）

 　　A standard set of balls for the snooker table consists of 15 reds, 6 colours and 1 white / cue ball. Historically, snooker balls were made exclusively from heavy ivory. Thankfully, these quickly became a thing of the past and were replaced before the Second World War by lighter¹ Crystallite balls made from the crushed shin bones of cows. Today, snooker balls are entirely² made from synthetic³ materials.

　　一套标准的斯诺克台球用球由15只红色球、6只彩色球和一只白/主球组成。历史上，斯诺克用球只能用沉重的象牙来制造。谢天谢地，这很快就成为了历史，在第二次世界大战之前，更为轻便的微晶球取而代之，它们由碾碎的母牛胫骨制成。而如今，斯诺克用球全部是用合成材料来制造。
