摘　　要：质量为Ｍ位于Ｗｅｙｌ坐标ｒ＝０，ｚ＝λ的Ｓｃｈｗａｒｚｓｃｈｉｌｄ黑洞度规，当Ｍ趋于无限大并保持有限时，就变成为质量ｍ为０的真空Ｃ度规，这表明，质量为０的真空Ｃ度规时空是无限大Ｓｃｈｗａｒｚｓｃｈｉｌｄ黑洞视界的邻域。it is proved that, the metric of a Schwarzschild black hole of mass M situated at r=0, z=λ in Weyl coordinate system if M approaches to infinite and is finite, becomes a vacuum C metric when mass m is equal to 0. The proof shows that, the space time of a vacuum C metric when m=0 is a neighborhood nearby the horizon of an infinite Schwarzschild black hole.
