A Study of the Accurate Method to Determine the Dividing Plane of Ship's Initial Stability Height and That of Ship's Comprehensive Stability

本文介绍了确定船舶初稳性高度界限面和综合稳性界限面的准确方法，通过对初稳性高度界限面问题的讨论，完善了载荷变动求取船舶初稳性高度变化量及改变载荷调整船舶初稳性高度的理论计算公式，并为船舶驾驶员在载荷变动时判断船舶初稳性高度的变化情况提供了准确可靠的方法。通过对船舶综合稳性界限面问题的讨论，建立了改变载荷求取船舶综合稳性变化量及调整船舶综合稳性的理论计算公式，为船舶驾驶员在载荷变动时判断船舶综合稳性的变化情况提供了准确可靠的方法。

This paper introduces the accurate method to determine the dividing plane of ship's initial stability height and that of ship's comprehersive stability and through discussion on the problem with respect to the dividing plane of ship's initial sta-bility height, it has perfected the theoretical calculating formula to obtain the variate of the initial stability heightand to adjust the initial stability height when ship's load changes. It has therefore provided an accurate and reliable method for deck officers to make reasonable judgement in the change of initial stability height when ship's load changes.In addition, it has, through discussion on the problem with respect to the dividing plane of ship's comprehensive stability, put forward the theoretical calculating formula to obtain the variate of the comprehensive stability and to adjust the comprehensive stability and has thus provided the accurate and reliable method for deck officers to judge the changable condition of ship's comprehensive stability when ship's load changs.
