Additional, we chose inert gas SF6 as the gas inside the microbubble, two nonionic surfactants (Span 60 and Tween 80) as the shell material of encapsulated microbubbles.
另外，膜厚度的增加和膜粘弹性的增加都使微泡振动的阻力增大，从而使散射谐波的幅度减小，但这种因膜厚或粘弹性变化而引起的差异在声压增大时会有所减弱。
However, if the amplitude excessed 90%, the mounts of larger bubble increase as the increasing time.
另外，选择惰性气体SF6作为微泡内气体，设计了基于两种非离子表面活性剂（Span 60和Tween 80）的包膜超声造影微泡的膜材料组成，使用声振法制备得到表面活性剂包膜的超声造影微泡；对制备过程中的声振条件进行优化，结果表明总体上振幅越大，处理时间越长，声振后溶液的总体积增加得越多，即产生的微泡量越大，并且平均粒径越小，但当声振幅度增大到90%时，随着声振时间的延长，主要增加的是大微泡的量，有效微泡的量无明显增加，因此最佳的声振条件选择为振幅90%，声振时间60s。
