流体动力学方程和由此产生的守恒律推导出的非粘性流体，在后牛顿近似的Brans-Dicke理论，并适用于问题的气体质量的动力学不稳定性。我们发现，布兰斯-迪克理论仅仅通过改变广义相对论中已经存在的项的数值系数来修正广义相对论的结果。广义相对论预言的动力学不稳定性在Brans-Dicke理论中被略微抑制。
The equations of hydrodynamics and the resulting conservation laws are derived for a non-viscous fluid, in the post-Newtonian approximation of the Brans-Dicke theory, and applied to the problem of the dynamical instability of gaseous masses. It is found that the Brans-Dicke theory modifies the results of the theory of general relativity only by changing the numerical coefficients of the terms already present in the latter theory. And the dynamical instability predicted by general relativity is slightly suppressed in the Brans-Dicke theory.
