摘要：
The head-on collisions between two ion thermal solitary waves in isothermal pair-ion plasmas containing charged dust grains is investigated. Using the extended Poincare-Lighthill-Kuo (PLK) method, the Korteweg-de Vries (KdV) equations and the analytical phase shifts after the head-on collision of two- solitary waves are derived. The results show that the number densities of positive and negative dust grains to the density of positive ion ratios and the negative-to-positive ion temperature ratio have strong effects on the phase shifts.
