The sockstreet attack first completes the tcp three-way handshake the tcp connection is established, but in the last ack reply of the three-way handshake, the attacker sets its tcp window to 0 and then makes a data request. When the target discovers that the TCP window size at the receiving end is 0 when transmitting data, it will stop transmitting data and issue a TCP window probe packet to ask the attacker if its TCP window has been updated. Since the attacker does not change the size of the tcp window, the target will always maintain the tcp connection waiting for data to be sent and continuously carry out window update detection. If the attacker uses a large number of controlled hosts to carry out sockstreet attacks, the target will always maintain a large number of tcp connections and carry out a large number of window update detection, and its tcp connection table will gradually run out.2. Thrombolytic therapy for thromboembolic diseases is one of the common diseases endangering health. Thrombolytic therapy is the most effective treatment. Thrombolytic drugs are applied to the formed thrombus. Fibrinolytic activator is used to convert plasminogen into fibrinolytic enzyme, so that thrombus can be dissolved in time, local blood circulation can be restored, and the function of tissues and organs affected by thrombus can be improved. A large number of data show that only 30% can autolyze after thrombosis, and about 50% can persist and no longer develop. Therefore, thrombolytic therapy in thromboembolic diseases, the earlier the treatment, the better the curative effect, especially the early recovery of important organs related to life, such as brain, heart and kidney functions, has more significant clinical significance.《鸳鸯剑侠》是《江湖奇侠》的延续篇，是卖座电影《江湖奇侠》之下集，同样以「火烧红莲寺」故事作其骨干。少年桂武（王羽）奉师下山，办理三件事，一到蟠龙谷甘家学艺，二找寻姑母，三为父母报仇。他到甘家后与甘女（秦萍）结婚，发现了甘父与劫镖有关，带甘家女儿出走。桂武凭机智武功，逐一闯关……May you be strong enough not to be spoiled or hurt.郑氏听了，也忍不住笑起来，又问绿菠和青蒜：你俩好了，心里不难受了？绿菠诧异道：咦。You can tell me first杨长帆作为主持司仪，当即起身宣布：喜事不隔夜。
