The submarine structure is simplified to single or double infinite cylindrical shell stiffened with rings, bulkheads and stringers, focusing on underwater sound radiation from the single shell. the shell motion is described by donnell ' s theory including excitation forces and reactions of rings, bulkheads, stringers and fluid, which leads to the fluid - structure coupling vibration equation. expressing displacements by velocities, applying modal expansion circumferentially and fourier transformation longitudinally result in the shell ' s modal equations of motion
殼體的運動方程採用較為簡單的donnell理論描述，運動方程中包括了激勵力、加筋結構（環肋、艙壁和縱骨）和流場對殼體的作用力，從而組成流場-結構的耦合振動方程，並進一步將方程中的位移用速度表示，然後沿軸線方向進行fourier變換，將速度和各項荷載沿圓周方向進行模態展開，得到了殼體振動的模態運動方程。 -

研究了三維空間計算機輔助船舶設計方法，對船體外板排列及展開、船體艙室劃分及計算、船體內部構件的參數化特徵造型等在三維可視環境下進行虛擬設計。 -
It s a good idea to get into the habit of using single quotes to surround your sed commands, so that shell expansion is disabled
養成使用單引號來括起sed命令的習慣是個好注意，這樣可以禁用shell擴展。 -
But with such a shell, we find that there emerges a deeper type of symmetry, not evident at first : for the shell has a symmetry under rotational motion, provided that this is accompanied by uniform expansion or contraction
但以蝸牛殼這樣的對稱狀態，我們其實是發現了一種更深層類型的對稱- - - - - -此為一種在旋轉的行動之下的新型對稱破缺，其原因來自於均勻的擴展或收縮的伴隨條件。 -
? by comparing the experimental data with the modeling results, it was found that the he in the projectile produces reaction after considerably long time. and the expansion velocity of the shell is about one hundred meters per second, far below the velocity driven by detonation ( about 2000m / s ). ? the post - test recovered fragments prove that the reaction violence remains on low level
?通過試驗結果和數值模擬的殼體邊界和徑向膨脹速度的對比分析，發現帶炸藥彈體在以120m s左右的速度撞擊鋼靶后，經歷了相當長時間后才產生反應，且此時殼體的膨脹速度僅在百米每秒的水平，遠低於爆轟驅動下能達到2000m s左右的速度。
