载荷变动对船舶稳性高度的影响及其计算方法

An Approach to the Influence of the Load Changes on Ship’s Stability and the Calculation

论述了载荷变动对船舶稳性高度的影响，提出了简便准确的计算方法，指出了《船舶货运》等教科书中关于少量载荷变动对稳性的影响及在定义、计算方法上存在的问题。若按这些书中的近似计算公式计算，在某些情况下甚至会得出相反的结论。

This paper discusses the influence of the load changeson the ship’s stability,and puts forward the simple and accurate cal-culation. It points out that in textbooks such as“Cargo Shipping”aboutthe influence of the littie changes in load on the ship’s stability, thereexist some questions in the definition and calculation. The calculation,if done according to the formalae put forward in these books, willsometimes lead to contrary results,thus affecting navigational safety.
