本文根据反武装直升机智能雷弹研制的需要，深入研究了智能雷弹被动声引信中的几个关键技术。

Near distance acoustic fields are payed attention in intelligent acoustic mine and the measurement of tranquil targets' radiate field and acoustic feature monitor of targets in the haven , etc.

"智能"水雷声引信、目标低噪声辐射声场测量和港口目标声特性监测等场合均关注近程(2Km以内)声场。

For the active acoustic fuze for a torpedo on the basis of the distance measurement done by using acoustic pulses, the echo of a randomly undulating wave is a main disturbance to recognize a surface ship.

摘 要：基于脉冲回声探测的主动声引信识别水面舰船，随机起伏的波浪回声干扰是限制其可识别水面舰船最小吃水的主要因素。

In order to contribute to analyse and compute easily setback moving devices on the projectile fuzes,and to make the fuze devisers be able to get the approximate acceleration curves with a few parameters such as tube length and muzzle velocity of the guns,the displacement-time curve and velocity-time curve of gun interior ballistic are fitted with the Logistic models,then the formula of projectile acceleration curves in bore are gotten by the derivation of the formula of fitting velocity-time curve.

为了便于炮弹引信后坐运动机构的分析和计算，能使引信工作者只根据身管长度和炮口速度等少量参数就能获得弹丸膛内加速度近似曲线，运用Logistic函数拟合火炮内弹道的位移－时间曲线和速度－时间曲线，再对拟合得到的速度－时间曲线求导便得到了弹丸膛内加速度近似曲线。

This simulated rocket can simulate the acceleration,thrust time,speed at burning end,rotation speed and so on satisfily.It is not only suitable for firing test during development,but also delivery test.This simmulated rocket does not require ideal experiment environment,is easy to be implemented.It is characterized by high security,low cost,shortening the fuze researching period and other benifits.

该弹可以相当满意地模拟火箭弹的加速度、推进时间、主动段末速、转速等主要参数，非常适合火箭弹触发引信研制中的靶场射击试验和生产交验，具有对试验场地要求低、试验简便、安全性高、成本低、有利于缩短引信研制周期等优点。

The fuze ball rotor is one of typical primary explosive safety devices in the fuze ofspinning projectile.

球转子机构是旋转弹药引信典型的隔爆机构之一，除主要用于满足引信隔爆安全性要求外，同时也可兼作延期解除保险。

To solve these problems,more than ten development countermeasures and suggestions are proposed such as using the experience of MIL-STD-1316,Fuze Design,Safety Criteria,for reference and setting up the special authorities and boards for reviewing the safety and the explosive ordnance disposal features of the fuzes.

针对这些问题，提出了借鉴美军《引信安全性设计准则》，建立引信安全性和爆炸物处理特性审查的专门机构和委员会等10余条对策建议。

The predic- tion of A5 explosive in-bore ignition probability was given. Accordingly. the in-bore safety of explosive charge of fuze explosive train componentsi was evaluated.

利用有限元计算结果，给出了引信传爆管和导引传爆管中A5炸药在膛内发射时的起爆概率，从而评价了引信火工品装药的膛内安全性。

The projectile flying rotation number is a key parameter to obtain the fuse operating distance in proximity fuse measurement by counting rotation number.

在计转数空炸引信测试中，可编程引信作用距离是关键量，而全备弹丸飞行转动圈数则是求取该关键量的测量难题。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
