As mentioned above, SYN attacks can be prevented by increasing the backlog queue. In addition, reducing timeout time also enables the system to process more SYN requests. We know that the timeout timeout, that is, the half-connection lifetime, is the sum of the timeout times that the system waits for all retransmissions. The larger this value, the longer the half-connection takes up the backlog queue and the fewer SYN requests the system can handle. In order to shorten the timeout time, it can be realized by shortening the retransmission timeout time (usually the first retransmission timeout time) and reducing the number of retransmissions.深夜，韩商言推门走入了一家小网吧。此时，计算机“鬼才”，在读研究生佟年为表弟家看管着网吧。单纯软萌的佟年对韩商言一见钟情。她勇敢，却连他十年前的绯闻女友都不敢细看；她淡然，却因害怕打扰他，连坐在身边偷偷瞄一眼都带着不安；她习惯了大场面，却因他在她微博下的留言而觉得呼吸都要停滞；她接受惯了采访，却在给他打电话时，准备了半天的话题，一个字都想不起来；她那么喜欢他，可是因为觉得对不起，却只能流着泪说分手。就是这样的佟年，打动了不近女色，早已波澜不惊的韩商言，也在韩商言的激励下，佟年重新加入校队，继续国际计算机学会世界编程大赛的比赛。两人各自投入到了夺取冠军的征程，在不同的领域大放异彩。在话唠体质的女干部罗英玮（李媛饰）的带领下，平陵市公安局档案室的三个年轻女警：“八卦小天后”蔡文心（施诗饰），美艳励志姐夏洛阳（蒲萄饰），沉默小文员冯壹（许愿饰），组成了一个让人瞠目结舌状况百出的破案小组。在蔡文心哥哥平陵市公安局刑警大队队长蔡文斐 （王雨饰）及其他前辈们的信任和帮助下，小组成员克服了无数困难，侦破了一桩桩冷案，也摧毁了平陵的贩毒集团的故事。在这一过程中她们明白了作为警察的意义，最终也成长为了优秀的警察。偏将痛哭道：将军——葫芦眉头一松，放下按住腰间宝剑的手。The pins on the PCB are dual-column or multi-column components and the layout direction of multiple discrete components regularly arranged should be as consistent as possible and toward the direction of the PCB under design in the production line, as shown in the following figure:你不是说有应酬吗？季木霖在电话里冷冷地质问。
