The power required to propel a new ship is subject to a formidable number of variable items. The family tree of power for propulsion (Fig. 1) shows these divided into two main groups. One is concerned with the resistance to motion caused by the interaction of the hull of the ship with the surrounding water

幂法 Power Method 计算矩阵的主特征根及对应的特征向量 原始幂法/ the original method 条件:A有特征根>+22…=0,对应n个线性无

The complete electrical plant on board ship is made up of power generation equipment, a distribution system and the many power utilising devices. Electricity is used for the motor drive of equipment. A constant supply of electricity is essend:lighting ventilation and air conditioning

2. B Power Cycles with Two-Phase Media (Vapor Power Cycles) [SB&vw-chapter 3, Chapter ll, Sections 11.1 to 11.7] In this section, we examine cycles that use two-phase media as the working fluid. These can be combined with gas turbine cycles to provide combined cycles which have higher efficiency
