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.传旨：今后边关起战火时，允许女子投军效力。这是一个远古时代恐龙家族如何生存的故事，其间反映了恐龙间的亲情和友情，并通过森林中的历险再现了它们的勇敢和诚实精神，此片给我们展现了一幅远古时期生物的进化图卷。布莱恩（布莱德利·库珀 Bradley Cooper 饰）是一名军火承包商，年纪轻轻的他便在行业内闯出了一片属于自己的天地，攀登上了事业的最高峰。某日，他被上司派往夏威夷火奴鲁鲁军事基地，那里正在进行一项间谍卫星的开发和研制，需要布莱恩的监督，布莱恩兴致勃勃的踏上了旅途。让布莱恩没有想到的是，在目的地，等待着他要和他一同共事，是一位名叫艾莉森（艾玛·斯通 Emma Stone 饰）的女飞行员，艾莉森冷若冰霜而又不苟言笑，着实是一个严肃而又无趣的女人，这令布莱恩感到十分郁闷，与此同时，布莱恩对前女友崔西（瑞秋·麦克亚当斯 Rachel McAdams 饰）依然抱有着不切实际的幻想，他联系到了崔西，企图和她破镜重圆。可眼下却顾不得这个，不然，他和淼淼就要饿死了。该剧模式类似美剧的《Columbo》或日剧《古畑任三郎》，描述以主角杉下右京警部和其搭档组成的只有两个人的警视厅特命系，解决无数案件的故事。来自小镇的女子渴望成为舞者，她打扮成男子在一家经营不善的变装酒吧表演。
