At that tail of the warhead, the drag armour-piercing firebomb is filled with a drag agent and a fireagent, Under the pressure of propellant propelling warhead, it will spontaneously ignite to produce open flame, So it can break through the oil drum and ignite or detonate the gasoline. However, the old-fashioned traced armour-piercing firebombs have obvious trajectories due to traced light when they are launched. Therefore, it is very easy to expose oneself while pointing targets to friendly forces. Therefore, the new tracer armour-piercing firebombs now equipped all start to burn and emit light only after the projectile flies out of the muzzle for a certain distance (the generally set safe distance is 100 meters, which makes it impossible for the enemy to judge the firing position with tracer ammunition, while targets within 100 meters do not need to be indicated by tracer), The principle is generally to ignite the tracer and combustion agent carried by the projectile by accumulating the heat generated by the warhead's friction with the air after flying for a certain distance to a certain extent.马丁·弗瑞曼将出演两部全新剧集，一部为Sky打造的《养育者》(Breeders，暂译)，另一部是ITV打造的《坦白第一季》(A Confession，暂译)。这下连黎章也奇怪了：老将军还在昏迷中，见他有何用？胡钧和汪魁一齐点头，等林聪解释。而所谓考了一辈子，依然是童生的人，即是考了一辈子，都没有通过院试的人，再直白说就是考了一辈子，都没有参加全国统考的资格，而且几乎连书生最基本的权益都没有，养家都是一个梦想，抑郁发疯自闭症什么的必将接踵而至，这是多么可怕的一件事。若是尹兄不嫌晦气，可愿与我一道去？愿意奉陪。Http://www.jiemian.com/article/2011673.html感觉活不下去的苍蝇，无法诉说梦想，过着OL生活…
