在拉格朗日重正化展开的系统方法导出的近似的基础上研究了湍流的惯性范围结构。该方法也适用于湍流对流的被动标量场问题，并检验了其一些后果。获得了惯性范围内各种无量纲常数的数值，包括湍流能量和标量场的 k−5/3 谱定律中的数值。
The inertial range structure of turbulence is studied on the basis of an approximation derived by a systematic method of Lagrangian renormalized expansions. This method is also applied to the problem of a passive scalar field convected by turbulence, and some of its consequences are examined. Numerical values are obtained for various dimensionless constants in the inertial range including those in the k−5/3 spectrum law for the turbulent energy and the scalar field.
