| 摘 要： | 将信息熵理论应用于喷雾油束液滴尺寸分布的研究中,提出了在两个约束条件下的液滴尺寸分布函数式,该式不是依赖于特定试验条件的经验公式,与广泛应用的分布函数相比具有许多相似和不同之处,较好地反映了实测的液滴尺寸分布变化趋势。

| Abstract: | Information entropy theory was applied to study drop size distribution of spray. The distribution function satisfying two constraints was produced that was independent of special experiment condition. Comparing with the distribution functions in existence, it had many similarities as well as distinctions. The present distribution function showed that the good agreement with varying tendency of drop size was measured in a practical test. |
