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.若她取他性命毫不手软，他也就死心了。史天雄从小由陆承伟的父亲陆震天一手养大并成了陆家的女婿，他是个对党对国家绝对忠诚的“圣徒”，而陆承伟却是一个随时利用成熟的市场经济价值体系指导行动的金融家。两人不同的信仰和价值观，以及不同寻常的兄弟关系和渊源引发出一场惊心动魄“两足相争”的人生话剧。The picture is from the simple book AppCinemax宣布预订由林诣彬执行制片﹑导演，以及《黑吃黑 Banshee》主创Jonathan Tropper当编剧，从李小龙所写项目当灵感的试映集《龙战士 Warrior》。该试映集背景在美国内战后，旧金山的唐人街；《龙战士》讲述一个年轻﹑从中国远道而来的武术达人， 发现自己卷入了唐人街的血腥战争中。FLAG_ACTIVITY_NO_HISTORY: The corresponding attribute in AndroidManifest is: android: noHistory= "true", the activity started by this FLAG, once exited, will not exist in the stack.翘儿利索找出了一应工具，杨长帆这便演示起来。
