【Abstract】 Bubble oscillation behaviors in the process of plastics foaming are studied.Base on the studying of plastics melt and gas of gas phase simultaneously controlling equation of bubble oscillation is achieved,and then discreted and mathematically simulated.Furthermore, bubble oscillation law is obtained.To provide the theoretic basis of controlling plastics bubbling effectively,influences of viscoelastics of plastics melt and gas of gas phase on bubble oscillation are discussed.更多还原
