在Brans-Dicke理论框架内给出一个新的球对称真空静态精确解，并显示这解有虫洞几何(wormhole geometry).若无量纲耦合常数ω(-2≤ω≤0)和积分常数适当地取值，则这解是双向可穿越虫洞(two-way traversable wormhole)解.标量场起异常物质(exotic matter)的作用，这一结果违背弱能量条件(weak energy condition).It is shown that a new set of exact solutions in vacuum Brans-Dicke theory is obtained and it admits wormhole geometry.Two-way traversable wormholes in the Brans-Dicke theory is allowed for the coupling parameter ω(-2≤ω≤0) and the appropriately chosen integration constants.It also follows that the scalar field plays the role of exotic matter and this violates the weak energy condition.
