The impacts of underwater turbulence on the average optical transmittance are investigated when optical cosine-Gaussian and optical cosine-hyperbolic-Gaussian (cosh-Gaussian) beam propagate in weakly turbulent underwater medium. Findings obtained by using MATLAB reveal that when the displacement parameter is smaller (larger) for the cos-Gaussian (cosh-Gaussian) beam, the average transmittance increases. Also, an increase in the source size results in elevated average transmittance values. Rate of dissipation of kinetic energy per unit mass of fluid is found to be directly proportional to the average transmittance. However, the rate of dissipation of the mean-squared temperature is inversely proportional to the average transmittance. Average transmittance is found to be essentially the same when the temperature-induced optical turbulence is dominant. An increase in the salinity-induced optical turbulence suddenly reduces the average transmittance of the cos-Gaussian and cosh-Gaussian beam in underwater turbulence. Finally, it is observed that for the same sized beams in the same underwaterturbulent medium, cosh-Gaussian beam will have larger average transmittance than the corresponding cos-Gaussian beam. As the influence and value of our research conclusion on the development of our research, we comment that cosh-Gaussian beams can be preferred over the cos-Gaussian and Gaussian beams in obtaining larger average transmittance in underwater turbulence.

研究了光学余弦高斯和光学余弦双曲高斯（cosh-Gaussian）光束在弱湍流水下介质中传播时，水下湍流对平均光学透射率的影响。使用MATLAB得到的结果表明，对于cos-Gaussian(cosh-Gaussian)光束，当位移参数较小(较大)时，平均透射率增加。此外，光源尺寸的增加会导致平均透射率值升高。发现每单位质量流体的动能耗散率与平均透射率成正比。然而，均方温度的耗散率与平均透射率成反比。当温度引起的光学湍流占主导地位时，发现平均透射率基本相同。盐度引起的光学湍流的增加突然降低了水下湍流中余高斯和余弦高斯光束的平均透射率。最后，观察到对于相同水下湍流介质中相同尺寸的光束，同高斯光束将比相应的余高斯光束具有更大的平均透射率。作为我们研究结论对我们研究发展的影响和价值，我们认为在水下湍流中获得更大的平均透射率时，高斯光束优于高斯光束和高斯光束。盐度引起的光学湍流的增加突然降低了水下湍流中余高斯和余弦高斯光束的平均透射率。最后，观察到对于相同水下湍流介质中相同尺寸的光束，同高斯光束将比相应的余高斯光束具有更大的平均透射率。作为我们研究结论对我们研究发展的影响和价值，我们认为在水下湍流中获得更大的平均透射率时，高斯光束优于高斯光束和高斯光束。盐度引起的光学湍流的增加突然降低了水下湍流中余高斯和余弦高斯光束的平均透射率。最后，观察到对于相同水下湍流介质中相同尺寸的光束，同高斯光束将比相应的余高斯光束具有更大的平均透射率。作为我们研究结论对我们研究发展的影响和价值，我们认为在水下湍流中获得更大的平均透射率时，高斯光束优于高斯光束和高斯光束。
