摘要：

Expressions are proposed for relating all the elements of the fourth-order two-point velocity correlation tensor to only the longitudinal scalar functions of this tensor when the turbulence is isotropic. These relations are checked against measurements in the self-preserving region of a turbulent plane jet (R-lambda similar or equal to 600). For small scales, the agreement is reasonable and represents a significant improvement over the use of the joint-Gaussian approximation.
