| 摘 要： | 从定义上分析了以“Ｐｐ＝Ｃｎ３ｐ”表征船舶航行工况所存在的问题。文章认为，以螺旋桨推进特性表征海洋运输商船的航行工况时，应明确定义其中反映各航行工况变化的标志性变量——螺旋桨转矩系数。同时指出了在大风浪中航行桨叶偶尔露出水面这一特殊工况时，其中标志性变量应是螺旋桨直径参数。

| Abstract: | The author of this paper considers that P p=Cn 3 p can't fully reflect the varible running working condition. The paper points out that we must define the torgue coefficient in the formula as the leading parameter during the running working condition of the merchant vessel. And it also should be defined that the diameter of a propeller is the leading parameter when the blade of propeller is partly above the surface of water. |
