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.就在这一刻，太阳升起，灿烂的阳光照耀大地和山峦，空气中洋溢着令人振奋的草木香气。原天桥风云主持人Heidi Klum与导师Tim Gunn在离开天桥风云后，携手Amazon制作了一档新的时尚节目Making The Cut，在全球发掘下一个具有潜力的设计师，在纽约、巴黎与东京等世界各地进行时装设计比拼。　　带你进入坚强背后的脆弱与不堪韩国小众电影，讲述了在一个山村里，一位记者的偶然出现打破了村子的宁静。因为他发现了一个 被隐藏已久的秘密，而且这个秘密和一位村子内神秘的女人有光。这个女人的饮食方式非常的与众不同，同时也非常让人毛骨悚然。
