然后，根据波浪中重力与浮力平衡、纵倾力矩之和为零这两个条件来求取横摇稳性力臂值。

Finally, the values of roll stability, in accordance with the condition of the balance between gravity and buoyancy of ship in waves and also with that the sum of trim moments is zero are obtained.

将气囊浮力力矩平衡关系式引入方程组，使多输入双输出耦合系统简化为多输入单输出系统。

The buoyancy force moment balance equation imposed simplifies the multi-input twi-output coupling (system) into multi-input single output system.
