The nonlinear rolling damping of a ship is usually determined by rolling attenuationtest in calm water.
横摇非线性阻尼通常是在静水中进行横摇衰减试验确定。

In this paper, the effect of waves on nonlinear rolling damping is researched experimentally through attenuationtest of a model ship rolling in irregular waves in a wave tank.
本文通过在波浪水池中进行不规则波的船模横摇衰减试验，研究了波浪对非线性横摇阻尼的影响。

X1 probe: no attenuation, input impedance follow that of scope input impedance (usually 1 Mohm). This type of probe is seldom used because of heavy loading effect on circuit under test.
