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.　　阿良担当起了企业重组的重要工作并且解雇了自己的同僚，因此自己也向公司提出了辞职。明里由于怀孕住进了医院，但却被姑姑满枝讽刺为太过娇惯。生了孩子之后明里带着孩子勇气回了东京，无法原谅舍弃了水耕栽培梦想的和夫，决意离婚。27一个瘦小的肩膀，能够承受多少压力？一个垂垂老矣的女人，又能承受多少生离死别？人间有情，希望长存是“飘零燕”一剧所带出的主讯息。小孤女叶宝燕自双亲先后去世，一直与内地来港的祖母汤秀琼相依为命，岂料天意弄人琼因外失忆而失踪。自此，二人各自展开飘泊人海的孤苦生涯。她们在残酷的社会中挣扎求存，饱尝人情冷暖。她们虽然得不到命运之神的眷顾，但却从未想过放弃，一直奋勇于生命激流中，盼着重聚一天的来临……Builder pattern can separate the construction of a complex object from its representation, so that the same construction process can create different representations.
