后续船 meaning in Chinese

following ship

Since kamen and vagena , many researchers have discussed it in theory and experiment method . the main content in this paper is to set forth the slamming press calculations in dnv rules , gl rules and lr rules and the requirements for slamming strengthened bow structure and some comparisons ; slamming strengthened bow structure design for a bulk is carried out using dnv rules , and comparisons among several design schemes is carried through when heavy loading draft status replaces light loading draft status in practice . the results from above have been applied in ship production ; it is significant for ship structure improvement latter to calculate slamming press with direct calculation method , and then to design bow structure with dnv rules
本文的主要内容是分别阐述dnv 、 gl 、 lr三种规范对底部砰击压力计算及底部砰击加强结构设计的一般要求并进行一些分析比较：用dnv规范对某型船( 27000t散货船)进行具体的底部砰击加强结构设计，并就实际生产中产生的重载吃水状态改轻载吃水状态而出现的几种设计方案进行比较，其具体结果现已用于实际生产；用直接计算法确定砰击压力，再用dnv规范进行底部结构设计，对于后续船的改进均有指导意义。
