本文用路径积分方法研究了协变闭弦场论的量子化问题，并特别考虑了BRS对称性。为了恢复被路径积分测度破坏的BRS对称性，我们依次修改了闭SFT作用量和BRS变换。由此产生的理论有正确的酉单圈振幅，但在更高的循环出现的问题。
Quantization of covariant closed string field theory (SFT) is considered in the path-integral formalism with special attention to the BRS symmetry. We modify the closed SFT action and the BRS transformation order by order in ħ to recover the BRS symmetry violated by the path-integral measure. The resulting theory has correct unitary one-loop amplitudes, but a problem arises in higher loops.
