摘要翻译：
由于伽利略不变性，随机强迫不可压缩流体的路径积分具有Becchi-Rouet-Stora(BRS)对称性。必须尊重这种对称性，使其具有一致的生成泛函，既不受整体无限因子的影响，也不受相关函数之间虚假关系的影响。我们提出了一个尊重这种BRS对称性的过程，类似于量子场论中的规范固定。导出了这种规范固定的BRS对称理论的关联函数之间的关系，类似于量子场论的Slavnov-Taylor恒等式。

英文摘要：
The path integral for randomly forced incompressible fluids is shown to have an underlying Becchi-Rouet-Stora (BRS) symmetry as a consequence of Galilean invariance. This symmetry must be respected to have a consistent generating functional, free from both an overall infinite factor and spurious relations amongst correlation functions. We present a procedure for respecting this BRS symmetry, akin to gauge fixing in quantum field theory. Relations are derived between correlation functions of this gauge fixed, BRS symmetric theory, analogous to the Slavnov-Taylor identities of quantum field theory.
