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.该片首次系统利用中国第一档案馆所藏的一千余万件清代档案，沿循清王朝二百六十余年由盛而衰的历史轨迹，真实再现了为人关注的历史人物、宫廷内幕和皇家隐私，揭开了诸多由来已久的谜团悬案。以领导世界造船事业的韩国造船业界为背景叙述年轻男女的爱与野心欲望之故事.......这次吕文心打电话过来，是想请陈启参加一个饭局，饭局中会有青龙影视的人，吕文心虽然没有细说，但是陈启不用想也知道，他们显然是为了他小说的影视版权而来。中国的抗日战争进入到最艰苦的阶段,缅甸沦陷,日军侵犯云南的畹町,龙陵,腾冲,滇缅公路被迫中断,由此,最后一条通往中国战区的通道也被切断,使外国援华的物资无法从缅甸运入中国……　这是一个讲述香港海关的故事，透过版权及商标调查科高级监督海锋(袁伟豪 饰)、贸易管制处总贸易管制主任关佩欣(黄智雯 饰)、海关毒品调查课监督温芷祺(王敏奕 饰)，三人带领一众海关菁英及年青新晋，包括有见习督察陈家兴(陈家乐 饰)，由鸡蛋管到原子弹、由奶粉管到白粉，海陆空全天候，展示出智慧海关的新面貌。这一群人，在自身的逆境里，也能够跨越难关，秉持护法守关、专业承担的宗旨，为本地社会的稳定与繁荣作出贡献，是香港人引以为傲的把关者们。悍匪龙志强，在香港回归前，趁香港英政府不作为，而屡犯巨案，先后绑架富豪利家及雷家之长子，勒索超过二十亿元，事主怕被报复, 交赎款后都不敢报警。中国公安部极为关注，与香港警方合力，派香港警员何天卧底潜入龙志强犯罪团伙，发现他正策划绑架澳门富豪贺不凡，最终陆港警察合力勇擒龙志强，救出贺不凡。
