论文摘要
偶极子场在电磁学中很常见，可以看作是靠近的正电荷（或极）的结果。由于从未观察到负质量，因此不预计重力中的偶极子场。但是，提出了对带扭转的重力场方程的精确解，即使没有负质量，也对应于偶极重力场。该理论基于非对称度量张量，发现原始张量的度量张量有一个奇异性，但没有事件范围。引力偶极子已被用来解决暗物质问题。
Dipole fields are common in electromagnetism and may be viewed as the result of a positive and negative charge (or pole) which are close together. A dipole field in gravity is not expected to exist because negative mass has never been observed. However, an exact solution to the gravitational field equations with torsion is presented that does correspond to a dipole gravitational field, even though there is no negative mass. The theory is based on a non-symmetric metric tensor, and it is found there is a singularity in the metric tensor at the origin but no event horizon. Gravitational dipoles have been used to solve the dark matter problem.
