Thread bubble growth and its oscillation has been research since the years and got considerable for researchers . Bubbles at different locations in the world can be seen as bubbles in the polymer industry and medicine manufacturing and construction (concreting steps) . What's this attention to the issue of how to control the bubble growth . For example, coarse or fine–grained nature of the polymer will determine how bubble growth and Or the protein that injected into a vein in the Medical If bubble growth not be controlled the created pressure can damage vital tissues (With this in mind that blood has nonlinear viscosity and it is visco–elastic fluid ) . To gain control of bubble growth effects of viscosity of bubble shell and Magnetic field together has been studied by solving the equation of herring and its development . in this work Non–linear oscillations of a viscoelastic gas bubble has been studied in affect of viscosity of bubble shell and Magnetic field . In addition, varying amounts of bubble shell viscosity and Magnetic field is considered and studied . And can see , control bubble growth by controlled of bubble shell viscosity and Magnetic field . and can reduce the hazards of uncontrolled bubble growth by this Method<\div>

The paper investigates the effect of heat transfer on spherical bubble growth in a semi infinite space. The study of bubble growth in heating or cooling systems is important such as in heat pipes or cooling of electronic devices. In this study, we have formulated a general bubble dynamics model.The velocity, density and pressure distributions for the gas inside a spherical bubble were obtained by analytically solving the continuity and momentum equations .Solving the energy equation for the gas inside the bubble yields the temperature distribution .The results show that liquid properties such as density, viscosity and temperature have an different effects on bubble behavior .Also, the gas properties such as gas conductivity influences the heat transfer between the bubble and the surrounding liquid, which finally influences the bubble growth amplitude<\div>
