Different combustion stages and the combustion performance of different fibers require corresponding flame retardants to be used to resist, thus forming various flame retardant mechanisms and interrupted flame retardant mechanisms. Flame retardant mechanisms can be broadly divided into the following types:这的确如陈启所说，是一场双赢。何况承影，断水两把宝剑，他们各执其一，注定了就是天作之合。夏日的阳光下，黑和银寻得了片刻的休憩。但是，幸福的时间并未长久，深重冷酷的黑暗已悄悄迫近。本是失去自我的DOLL的银在与黑共处的日子里，渐渐开始表现出自己独立的意志。对银的变化感到困惑焦躁的黑，却并不明白这意味着怎样的事实In the case of a reflection attack, An attacker uses a controlled host to send a large number of packets, What makes these packets special is that, The destination IP address points to the server, router, and other facilities that act as reflectors, while the source IP address is forged as the target IP address, When the reflector receives the data packet, it will think whether the data packet is requested by the attack target, so it will send the corresponding data to the attack target. When a large number of response data packets flock to the attack target, it will deplete the network broadband resources of the target, resulting in denial of service attacks.杨蓉站了起来，一脸严肃的向陈启行一个礼。
