抗沉性

船舶静力性能是船舶的最重要的性能之一，包括浮性、稳性、抗沉性等等。

The ship static ability is one of the most important abilities .

该装置的使用可有效提高船舶稳性、抗沉性、减摇性和防倾覆能力。

The use of this device can effectively improve the steadiness , sink-resistibility , roll-weakening and overturn-preventing .

潜艇是海军重要的组成部分之一，由于需长时间处于水下执行任务，当遇到事故需紧急上浮时，动力抗沉性就显得至关重要。

Submarine is a impotent component of the navy . Due to the need of taking a long time in the underwater mission , dynamic anti-sinking capability of submarines is very impotent when the submarines are damaged and needed emergency surfacing .

基于船舶不沉性理论，运用符拉索夫抗沉性计算法确定船舶破损后浮态参数之后，作出波浪上船舶破损浮力曲线，继而计算了波浪弯矩和波浪剪力；

Based on theory of floodability , the paper applies Vlasov 's calculation method to determine the floating parameters of damaged hull , discusses the buoyancy curve of damaged hull on wave , and calculates wave bending moment and wave shearing force .

混合处理后的粉末配制的达克罗涂液易分散，搅拌时间短、抗降沉性好、遮盖力强。

Dacromet coating solutions prepared with mixed metal powders are easy to be dispersed with short-time agitation and have good anti-settlement and covering force .

用桐油石灰抹缝，提高粘结性和抗渗性，使船舶具有很好的抗沉性。

Tung oil was also used in the shipbuilding to improve the caking property and impermeability of the watercraft .
