In comparison to the fetch-limited wave regime, the available data for duration-limited growth condition is very limited. Mutual conversion of these wave regimes is of interest and significance in all of the parametric growth functions proposed so far. Therefore, field-based heuristic relationships have been proposed to convert fetch-limited evolution data into duration-limited domain. However, considering the difficulty of collecting field-based duration-limited wave data, the reliability of the proposed equations is quite questionable. The main aim of this study is to provide experimental measurements describing the fetch-duration conversion of the dominant spectral characteristics of the water waves under steady wind action. The measurements of the present experimentations are supported by the analysis of the energy balance equations governing the wind energy expenditure during each wave scenario. The results manifested the co-existence of two different fetch-duration transition domains for each individual wave height and wave period. Analytical solution of the time-space connecting integral resulted in a conversion equation that was in good agreement with that obtained from the experimental data based on equivalent peak period. It is also demonstrated that although the experiments introduced here were carried out at the initial stages of the wave growth, the obtained results were in good agreement with those reported in more developed growth conditions.

与取回限制波态相比，持续时间受限制的生长条件的可用数据非常有限。这些波态的相互转换在迄今为止提出的所有参数增长函数中都具有兴趣和意义。因此，已经提出了基于字段的启发式关系，以将获取受限的演化数据转换为持续时间受限的域。但是，考虑到收集基于场的持续时间有限的波浪数据的困难，提出的方程的可靠性是非常值得怀疑的。这项研究的主要目的是提供实验测量值，以描述在稳定的风作用下水波的主要光谱特征的获取-持续时间转换。本实验的测量结果得到了对控制每个波浪情景期间风能消耗的能量平衡方程的分析的支持。结果表明，对于每个单独的波高和波周期，两个不同的提取持续时间过渡域共存。时空连接积分的解析解得出了一个转换方程，该方程与从基于等效峰值周期的实验数据获得的转换方程非常吻合。还证明了，尽管此处介绍的实验是在波浪生长的初始阶段进行的，但所获得的结果与在更发达的生长条件下报道的结果相吻合。结果表明，对于每个单独的波高和波周期，两个不同的提取持续时间过渡域共存。时空连接积分的解析解得出了一个转换方程，该方程与从基于等效峰值周期的实验数据获得的转换方程非常吻合。还证明了，尽管此处介绍的实验是在波浪生长的初始阶段进行的，但所获得的结果与在更发达的生长条件下报道的结果相吻合。结果表明，对于每个单独的波高和波周期，两个不同的提取持续时间过渡域共存。时空连接积分的解析解得出了一个转换方程，该方程与从基于等效峰值周期的实验数据获得的转换方程非常吻合。还证明了，尽管此处介绍的实验是在波浪生长的初始阶段进行的，但所获得的结果与在更发达的生长条件下报道的结果相吻合。
