Ship motions Ship motions are defined by the movements from the equilibrium position of the ship's centre of gravity along the three axes shown in Figure and by rotations about axes approximately parallel to these. The linear displacements along the horizontal

Planning Delivery of a completed ship by a specified date requires careful planning. Following the introduction of the critical path method of planning and control by the U. S. E. I. du Pont de Nemours Company' about 1959, new techniques were adopted in many shipyards

超基性岩和超镁铁质岩是两个不同的概念,前者是以SiO2 含量为依据命名的,后者是以富铁镁矿物而命名的,云S 数超镁铁质岩都是超基性岩。但某些超镁铁质岩如辉石岩、 角闪石岩等,其SiO2应属基性岩的范畴,但它们几乎不含长石 ,且常与橄榄岩等密切共生,因此一般放入超基性岩类中介 绍
