TCB (TCP? Transport Control Block is a transport protocol data structure that contains all the information of the connection (in fact, in many operating systems, it is a queue used to process inbound connection requests. The queue holds TCP connection items that are in a half-open state and items that have established a full connection but have not yet been extracted by the application through an accept () call). The amount of memory occupied by a single TCB depends on the implementation of TCP options and other functions used in the connection. Usually a TCB has at least 280 bytes, which in some operating systems has exceeded 1300 bytes. The SYN-RECEIVED state of TCP is used to indicate that the connection is only half open, and the legality of the request is still questioned. An important aspect worth noting here is that the size of TCB allocation space depends on the SYN packets received-before the connection is fully established or the return reachability of the connection initiator is verified./lay (lie down)接二连三遭受打击的甄兵兵选择了逃避，她收拾行李离开北京回到了自己的老家。甄兵兵走后，郑嘉楠才真正意识到甄兵兵在自己生命中的地位。郑嘉楠鼓足勇气来到了甄兵兵的老家，两人有几次在街头擦肩而过却最终未能见面。回到北京后，郑嘉楠用自己多年以来积攒起来的信誉担保，终于为甄兵兵证明了清白，大批粉丝开始对甄兵兵转变了态度。甄兵兵的粉丝数量终于恢复到了以前的水平。一个来回后，毫无发现。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.安然（孙雅 饰）和丈夫欧阳一峰（安泽豪 饰）结婚多年，两人共同养育着可爱的女儿蒙蒙（高欣宇 饰），生活虽然平淡，但却充满了幸福。安然唯一的遗憾就是家中比上不足比下有余的经济状况，然而欧阳一峰向来淡泊名利，并不愿意为了获得更好的生活而努力拼搏，小小的失望埋藏在安然的心底，渐渐生根发芽。江南大学艺术系三年级学生文潇雨是个清丽脱俗，多才多艺的女孩。父亲文景山得了尿毒症，为了给父亲治病，只好被相恋的同学罗晓明误解，离开大学，来到月亮宫娱乐中心打工。她美妙的歌声，出众的品貌和才华，吸引了众多捧场的男人。江东市赫赫有名的亿万富翁样志鸣、大老板李海文、珠宝富商秦勉、毫侠仗义的个体老板魏刚……他们围绕着文潇雨、娱乐中心老板何伟和情妇——文的中学同学陈丹莉，服务员世间“冰美人”林芳，演绎了市场经济的大潮中当代都市各色人等的心路历程，观念砥砺及命运交易，李海文爱上了林芳并生了个儿子，杨志鸣通过文潇雨的小学老师沈静知道自己是文潇雨的生父，而采取措施不让别的男人接近文潇雨，并采取种种手段对接近文的男人予以打击。罗晓明为了给文父治病不惜卖身一位富婆并拿到了订金，而文潇雨爱上了外表丑陋而内心善良的魏刚，但魏刚始终不接受文潇雨的爱。何伟破产了，陈丹莉吸毒赌博并出于嫉妒毁了文潇雨的容……
