研究了紊流水中球面激励的波结构函数（WSF）的特征。结果表明，随着湍流动能e耗散速率的减小，WSF增大。均方温度X-T的耗散率与WSF值成正比。源轴和接收轴的偏离显示出更大的湍流效应。与温度驱动的湍流相比，盐度驱动的湍流给出了更大的WSF值。正如预期的那样，WSF随着传播距离的增加而增加。
The features of the wave structure function (WSF) derived for spherical excitation in turbulent water are investigated. It is found that as the rate of the dissipation of turbulent kinetic energy e decreases, WSF increases. The rate of dissipation of the mean-squared temperature X-T is observed to be proportional to the WSF value. Deviation from the source and the receiver axis reveals greater turbulence effect. Salinity driven turbulence gives greater WSF values compared to the temperature driven turbulence. As expected, WSF is found to increase as the propagation distance increases.
