The purpose of this thesis is to reserch and design a digital fish torpedo SONAR pulse detect system, to solve some defect which exist in traditional SONAR, to accomplish real-time detect the aim and judge the aim's type and estimate the center frequency, angle, dsintance, repeat period of target, to follow the fast moving target, as well as to adapt the system to different flank three sub-array types without the limitation of installation place.

本文的目的在于研究并设计数字式鱼雷声纳脉冲侦察系统，解决传统声纳中存在的一些弊端，实现对鱼雷脉冲信号的实时检测，以及对信号的种类，中心频率，目标的方位，距离信息，重复周期的估计，对快速运动目标的跟踪测距，使系统不受安装场合的限制，适用于不同的舷侧三元子阵。

When a torpedo or contact mine explodes under the bottom of the ship, the result is widespread serious damage to structure and machinery in the affected area, since it is impracticable to provide the necessary torpedo-protection layers underneath the ship to completely guard against this type of attack.

当鱼雷或是触发引信水雷在舰底爆炸时，损害将会广泛传播并对该区域的舰体结构和机械设备造成巨大的伤害，这是因为在舰底不可能布置所需的鱼雷防护系统来抵御伤害。

Hypervelocity is a important direction of the torpedos progressing. Supercavitation is a feasible way for the hypervelocity motion of torpedo.

超高速是鱼雷发展的一个重要方向，超空化是实现鱼雷超高速航行的一种可行方法。

This paper based on the principle of having the underwater explosion as a interference source to make the guidance system of torpedos failure, and according to the similarity theory to equivalent the real situation into test model , and analysis the damage

论文文摘本文基于水下爆炸作为干扰源使鱼雷制导系统失灵的原理，应用相似理论，将实际情况等效缩比为试验模型，分析该等效模型在水下爆炸作用下的破坏情况以及对鱼雷自导系统的影响。

This study is done for the first time in domestictOrpedo business, the mathematic model of cowterrotating motor is established andsome sPecial characteristics of torpedos drive cowterrotating DC motor under theload of constant torque or the load of cowterrotating propellers are exposited.

这项研究在国内同行中还是首次进行，它建立了鱼雷双转推进电机的数学模型，揭示了鱼雷双转推进电机在恒力矩负载和对转螺旋桨负载下的一些特殊特性。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
