表面活性物质B(surfactantproteinB,SP-B)是肺泡表面活性物质的基本成分,起着减小肺泡表面张力的作用,对于出生后呼吸适应是必需的。
Surfactant protein B ( SP-B ) is an essential component of surfactant . It plays a role of diminishing alveolar surface tension , and is required for postnatal respiratory adaptation .

肺表面活性物质由磷脂和与其特异性结合的蛋白即肺表面活性物质相关蛋白(SPs)组成,前者能有效降低肺泡表面张力,而后者是磷脂发挥作用必不可少的部分。
PS is composed of phospholipid and the specific combined proteins ( surfactant associated proteins , SPs ) . Phospholipid can reduce the surface tension of alveolus , SPs are the necessary part in this process .
