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.可是，难道今晚就白来了？难道他就要这样放弃了？带着满心的不舍，他看向紫茄，却发现小姑娘正对着他微笑。见到李斯的表情，尉缭便知道他咋想些什么，安慰道：别想那么多，顺其自然就好。现在终于以这样一种方式要进入结局阶段，可是范亚父已经不在认识你了。我先前想着，要是皇上逼咱们，我就把你拐走呢。Through the screening of films on safeguarding rights in rural areas, improving farmers' legal awareness and enhancing farmers' legal concept are the spiritual factors for the sustainable development of rural society and the arduous task of rural legal construction.
