Since there is a great deal of confusion over the distinction,a writer is well advised to substitute expressions likeevery two months or twice a month where possible. However, used as nouns to denote “a publication that appears every two months,”the words withbi- are unavoidable. Bimonthly 和 biweekly 意为“每两个月一次”和“每两个星期一次。” 如表示“一个月两次”或“一个星期两次”，应该用semimonthly 和 semiweekly。 因在区别上存在很大混乱，建议作者尽可能用every two month 或 twice a month 的表达法代替。 但当用作名词表示“每两个月出版一次的刊物（双月刊）”时，不可避免地要使用含有bi- 的词 bi- 2 bi- 2 pref.（前缀）Variant of bio- bio-的变体 Bi Bi NONE（无词性）The symbol for the element bismuth 元素bismuth的符号 bi 1 bi AHD: [bº] 【俚语】 D.J.
