Added resistance,一般表示“附加阻力”,这应该是船舶结构设计术语；
参考下文.
Added resistance in waves is an important part of ship dynamic due to its economical effect on ship exploitation.Can the ship sustain speed in a rough sea state?If not,this will produce delays and economical losses if added resistance is not taken into account in the propulsion design.There are not many simple methods to obtain the added resistance in waves of a ship,and the validity of the results is not always good enough for different ships.In this paper,some theories that can be used to predict the added resistance of a ship are studied and validated against seakeeping tests of some monohull models.Tests and results focus in head seas,which are the most severe for the added resistance.Experimental results are compared with numerical calculations and conclusions about the range of application of the presented theories are obtained.
不过用于,电气专业的话,表示“附加电阻”.
