Using the degeneration technique, we study.the behavior of Welschinger invariants under the blow-up.and obtain some blow-up formulae of Welschinger invariants..To analyze the variation of Welschinger invariants when.replacing a pair of real points in the real conguration by.a pair of conjugated points, Welschinger introduced the -.invariant. In this paper, we also verify that the -invariant.is the Welschinger invariant of the blow-up of the symplectic.4-manifold.
