    摘要: A microfluidic system comprises a microchannel, a carrier fluid in the microchannel, and at least two plugs in the microchannel. Each plug comprises a plug fluid that is substantially immiscible with the carrier fluid. The microfluidic system further comprises at least one spacer in the microchannel between two plugs. Each spacer comprises a spacer fluid that is substantially immiscible with the carrier fluid and the plug fluid, and both of the following conditions are satisfied: (γc-r+γt-r>γc-t) and (γc-t+yt-r>yc-r), where γc-r is the interfacial force between the carrier fluid and the plug fluid, γt-r is the interfacial force between the spacer fluid and the plug fluid, and γc-t is the interfacial force between the carrier fluid and the spacer fluid.
