摘要：

We analyze the evolution of the rotational-type cosmological perturbation in a gravity with general quadratic order gravitational coupling terms. The result is expressed independently of the generalized nature of the gravity theory, and is simply interpreted as a conservation of the angular momentum. [S0556-2821(97)01822-5].
