液面反射波信号主要在硬件方面采用双通道二阶有源低通滤波，功图信号则在软件方面采用数字滤波算法。
Reflected wave signal is processed by double channels two-order low-pass active filtering in hardware, and indicator diagram signal is processed by digital filtering in software.
通过与规范的近似计算法的比较，阐述了不同方法对不同液舱形状进行自由液面修正时的准确程度。
And its veracity is compared among the regulation correction and the center of gravity shifting correction by calculating the free surface influence of different shape of tank.
