水雷

The present work studies the dispersion in different depths of a certain hydrobomb under different directions and velocities of seawater.

对某型空投水雷在不同流速流向条件下的水下不同深度的散布进行了仿真研究。

Finally, the hydrobomb's dispersion in different depths under different directions and velocities of seawater is studied and discussed in many kinds of initial condition.

用Matlab软件编写了空投水雷水下散布仿真程序，并对不同流速流向条件下多种初始条件的水下不同深度的散布进行了研究，给出了仿真结果和分析。

Firstly, this paper analyzes the forces acting on hydrobomb's body and empennage respectively. Then the mathematical model of hydrobomb's trajectory in seawater is discussed. Secondly, the simulation program is completed with Matlab.

分析了空投水雷水下无动力运动过程中雷体和尾翼的受力情况，并在运动受力分析的基础上给出了研究其水下散布的数学基础－水下无动力运动弹道仿真数模。

There has been significant speculation that Navy dolphins are trained in attack missions, such as direct attacks against swimmers in the water or attaching limpet mines to enemy ships in harbor.

曾有大量猜测称，海军的这些海豚是受训来完成攻击任务的，如对水下游泳者的直接攻击或是将吸附式水雷贴附到港口中的敌军船只上。

After all, other naval powers have done so for decades after German engineers during World War II invented the magnetic mine.

毕竟，其他的海军力量在第二次世界大战期间德国工程师设计发明磁性水雷之后已经这么做长达数十年之久。

Three of the marine mammal teams are trained to clear enemy sea mines, which constitute a major hazard to U.S. Navy ships.

在海洋哺乳动物小组中，有3组是受训清除对美国海军船只构成主要威胁的敌军海洋水雷。

By September, she was assigned to the Baltic Sea. On 17 November 1914, she struck two mines laid by Russian destroyers west of Memel.

截至当年9月，她被分配到波罗的海。1914年11月17日，她在Memel以西被两枚俄罗斯驱逐舰布下的水雷击中。

17Th November - German cruiser 'FRIEDRICH CARL'(1903, 9,700t, 4-21cm). On her way to bombard Libau, armoured cruiser 'Friedrich Carl', serving as a coastal defence ship, sinks on two mines in a Russian field laid by destroyers, west-southwest of Memel (54-41N, 20-11E).

11月17日-德国巡洋舰"腓特烈·卡尔"（建造于1903年，9700吨，4门210mm炮）。，装甲巡洋舰"腓特烈·卡尔"作为海防舰在前往炮击Libau的路上被两枚俄军驱逐舰布置的水雷击沉，其沉没于克莱佩达西南（54-41N，20-11E）。

Result the following day De Jun minelayer bumps in oneself last the mine below cloth is sunken.

结果第二天德军布雷艇撞中自己上次布下的水雷沉没。

This brought fixed cost, but it also is meant at the same time use a source to won't make you singlehanded assume a problem.

这带来了一定的成本，但它同时也意味着使用开源不会让你独力承担问题。
