%X Experiments were performed on the migration and interaction of two drops under the action of an applied temperature gradient on the ground. Pure soybean oil and silicon oil were used as continuous medium and as experimental medium in drops respectively. Images of these experiments were recorded and later analyzed to obtain data on the trajectories and velocities of two drops. The results demonstrate that the effect of the larger drop on the motion of the smaller one becomes significant with the two drops approaching each other, while the effect of the smaller one on the larger remains weak. And the oscillation phenomenon of migration velocities of both drops is found during the approach. Even the smaller one moves backwards in a short time when two drops migrate side by side. They display the congruence and difference between the experimental results and numerical simulations.
