摘要
作为可膨胀性、几乎可膨胀性和几乎θ可膨胀的自然推广，引入了Ｂｉ可膨胀性的定义，ｉ＝０，１，２．初次研究了Ｂｉ可膨胀性的特性．
The difinitions of B i expandabilities,i=0,1,2 as the natural generalizatins of expandability,almost expandability and almost θ expandability are introduced respectively.The characterizations of the B i expandabilities are studied first.
