| 4. | Midship section design is a vital step among ship ' s design . this section endures most bending load , and materializes the structure of the whole ship
船舯所受弯矩最大，是全船结构主要矛盾之所在，组成了船体结构的全局性构想，因而是船舶设计的重中之重。 |
| 5. | Wherethe long bridge deck within 0 . 5 l amidships is regarded as strengthdeck , the midship section modulus and minimum thickness of the deckplating comply with the requirements of 2 . 2 . 1 and 2 . 4 . 2 . l of this ischapter

| 6. | That means data and graph are divided completely . author noticed that these days , many researches about the design of midship section are focused on the scantling of the component in the preliminary design phase
本人注意到现今国内外对船舯结构设计的研究多集中在初步设计上，即定出舯剖面的框架；而在局部设计中却鲜有作为。 |
| 7. | In this paper we present in detail the process of midship section design and drawn procedure , coding shipping section plane cad application program through using microsoft visual c + + 6 . 0 , objectarx2000 programming languages and using grade optimistic method of optimization method . software design adopt windows attribute dialog box and common dialog box alternate designed means , people - computer interaction interface novelty , usableness
本文对船舶结构设计中的中横剖面设计和绘制程序进行了研究，利用autocad软件的二次开发功能，通过采用microsoftvisualc + + 6 . 0 、 objectarx2000编程语言和使用最优化方法中的分级优化方法，编制出了船舶剖面cad应用程序。 |
| 8. | During the process of the midship section design , drawing and calculating are carried through crossly ; moreover , with the development of this step , design of detailed structures would be deepened continuously . so drawing and calculating of the midship structure must be modificated again and again , until the perfect consistence between the data and graph is realized
在进行舯部结构设计时，绘图工作与计算工作一般是交叉进行的；而且，随着结构设计阶段的发展，局部性结构设计不断深化，舯部结构的计算和图纸的绘制均不免要反复加以修改，直到彼此能相互准确呼应。 |

船舶在由波浪弯矩引起的交变应力作用下，船体构件焊接点处的微小裂纹逐渐扩展；同时，随着船龄的增加，众多结构构件遭受腐蚀的作用；从而使船体梁剖面模数减小，船体梁承载能力衰减，船舶结构的安全性将受到相当大的影响。 |
| 10. | From the study results it is showed that turret hole position near the forward of the midship has less effect to the ship girder strength and it is more reasonable using probabilty statistics method to estimate the extreme value of wave bending moment , by which the first approximate value of hull midship section modulus can be determined
研究结果表明：转塔开孔位置在舯前附近对船体总强度影响不大；波浪弯矩极值用概率统计方法估算更为合理；船体结构剖面模数的第一近似值可用波浪弯矩设计极值等来确定。 |
