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.刘家父子婆媳听了，虽然是实情，心里却老大不痛快：难道穷家小户成亲也比人低一等？是不是因为黄瓜是老二，又没有官身。After completing 4 tasks, you will get some blue costumes and some talent points when you return to hand in the tasks.　　宋尧出身贫寒却极具才气，凭借自身的智慧成为宋氏集团的执行长。机缘巧合，相遇失意的程桦，在宋尧的相助下，认清邵钧真面目的程桦华丽转身，成为一名时尚的当然也包括西河村尹旭和平武那场经典的比拼，也像长了翅膀一样，远播天下。Regular Inspection and Maintenance Information of Fire Fighting Facilities林佳乐、林佳琪、王志伟和江乘风，四名在不同领域的工程师，抱着同样为人类未来造福的梦想的同时，也寻寻觅觅地在这世界上找着自己梦想中的另一半，四人到底最终是否能梦想成真呢？梦想开始：佳乐渴望爱情，又害怕爱情，全因心中的“魔咒”作祟，担心一旦对身边男子有好感，对方便会遭到不幸，因此对男人，佳乐是望而却步，深怕自己会情不自禁喜欢上对方。佳乐第一次碰到志伟，对志伟却是厌恶到极点，误会志伟抢劫了了父亲王强。佳乐为了惩罚志伟，把志伟抢劫父亲的片段上载到网路，让志伟顿成了过街老鼠，人人喊打。没想到冤家路窄的两人，偏偏原来是同事。志伟不但是佳乐的新上司，佳乐还无意中救过志伟，可是佳乐从来没有告诉志伟真相，志伟也一直以为救他的是司徒艳。和佳乐不同，佳琪对爱情是充满理想的，可是期待的真命天子却迟迟未出现，直到那一天佳琪遇到了乘风。乘风到佳琪的公司维修机器，意外害得佳琪扭伤脚。乘风见佳琪受伤，好心送她到画室上课，不巧写生的模特儿没到，佳琪于是乘机报复，推乘风上阵。乘风受不了激将法，冲动答应，却没想到原来是充当人
