国外发达国家现役的深弹配备的都是非触发式近感引信，攻潜效能高。
In overseas develop countries; however, the service depth bomb weapons are equipped with non contact fuze that has high effectiveness in attacking underwater craft.
目标特征提取技术是深弹近炸引信系统中的一个重要功能模块，是引信系统成功识别目标的关键。
Target feature extraction plays an important role in the depth bomb fuze system, because it is a key point that ensures the fuze system of successfully recognizing target.
深弹引信在对目标进行探测的过程中会遇到来自邻近深弹回波信号的干扰，邻弹干扰是导致虚警概率增加的最主要因素。
In the process of target detection, depth bomb fuze will undergo the interference from echo signal of neighborhood bomb that is the primary factor which causes high false-alarm probability.
它采用高孔密大孔径深穿透射孔弹和大压差抽吸炮眼清洗技术，不仅能提高油井产能，解除近井带污染，还可以改善防砂完井效果。
The technology uses deep penetration perforation charge with high perforation density and large perforation diameter and surging perforation with greater pressure differential.
