但是日本的船发起了突然的攻击并且在港口摧毁了许多美国船只。 |
| 6. | Secondly , for 74500dwt bulk carrier , the strength calculation and analysis of bottom structure in forward area , which bear big act force during ship launching , are carried out
其次，对船在下水过程中承受很大支反力的艏部区域底部结构进行了强度分析计算。 |
| 7. | Stress and deformation was calculated with the distribution to predict the security of structure where fem is used . with calculating in method of fem , the paper gives some advice on how to design structures of ship launching
将墩木支反力按照上述分布形式加载到三维有限元模型上进行计算，得出结构的应力响应和变形，然后校核是否满足要求，对下水船局部结构的安全性进行预报。 |
| 8. | The $ 1 . 40 stamp shows the ancient compass as a south - pointing ladle . the stamp depicts a hodometer developed from a compass cart and a ship launched by zheng he ( ad 1371 - 1433 ) , a world - renowned navigator , during his epoch - making expeditions
背景绘画记里鼓车以及明朝三宝太监郑和（ 1371 - 1433年）下西洋所乘船舰。前者在指南车的基础上发展而来，后者远洋航行，依赖的是导向的指南针。 |
| 9. | Ship launching is the key procedure during ship building , most coastal shipyard adopt longitudinal gravity launching method , the existing method for calculating ship launching include regular hydrostatic method and elastic calculation of ship launching
船舶下水是船舶建造过程中一个重要环节，我国沿海大、中型船厂大都采用船舶纵向重力式下水这种下水方式，现有的计算方法主要有：传统的静力学计算方法和弹性计算方法。 |
| 10. | At present , more and more large tonnage ships are built with the development of ship industry , the force between hull and shipway increased , the damage of ship structure was also reported . but the existed method is not efficiently for calculating the distribution of force acted on forward during stern floating which is the moment of truth during ship launching , so it is important to calculate ship launching precisely and take measure to preclude such accident
目前随着船舶工业的发展，建造船舶吨位越来越大，船体所受滑道反力随之增大，在实际生产过程中已有船体局部结构不同程度损坏的报道，而现有的下水计算方法在下水的最危险时刻艉浮时滑道反力的分布情况方面的计算显得不够准确，如何准确进行计算并采取相应的措施来防止这类问题发生显得十分重要。 |
