给出与Ａｃｃｅｔｔａ等人所得到的完全不同的Ｂｒａｕｓ－Ｄｉｃｋｅ（B－Ｄ）理论真空虫洞解，且表明这类虫洞与所得到的其他虫洞不同，其喉的尺度是随着Ｅｕｃｌｉｄｅａｎ宇宙时间的增大而线性增大。In this paper, we give an Euclidean wormhole solution in the vacuum Brans-Dicke theory, which is different from that obtained by Accetta et al. We show that this wormhole unlike all the others, it's throat dimension increases linearly with the increasing of the Euclidean cosmic time.
