中文摘要	The dynamic behavior of particles on a bubble interface contains axial and radial motions and is highly dependent upon the energy of this system. By introducing the concept of particle energy density (the average of the system energy based on particle number), four kinds of energy elements are estimated as critical elements, namely surface energy, line tension (an additive interaction at the contact line), electrostatic interaction and hydrophobic interaction (only for hydrophobic particle whose contact angle is greater than 64 degrees). With consideration of different energy influences, the radial motion, vertical to bubble interface, and circumferential motion, parallel with bubble interface, are theoretically described and discussed.; Natl Cheng Kung Univ
