It is convenient for fighting and evacuation, and a circular fire lane should be set up. With the accelerating pace of urbanization, urban land is increasingly tight, which promotes the construction of high-rise buildings. Many high-rise buildings, due to poor consideration of fire prevention design and other reasons, have many congenital hidden dangers, and fires occur from time to time, causing heavy losses. In order to create convenient conditions for fire fighting and rescue work and ensure the safety of buildings, circular fire lanes should be set up around high-rise buildings. However, regardless of the size of the building, it is indeed difficult to require the circular fire lanes. Lanes can be set up along the two long sides of the building. In order to prevent the collapse of building components in case of fire from affecting the normal operation of the fire lane, the distance between the fire lane and the outer wall should be 5m. There should be no trees, overhead pipelines, etc. that hinder the operation of climbing fire engines between fire lanes and high-rise buildings. If the total length of the building exceeds 220m, a fire lane shall be set up to pass through the building. There is no inner courtyard in the building, there are ring fire lanes around it, and fire engines crossing the building need to be set up. Q: An L-shaped high-rise building has a total length of about 170m, a length of 120m along the street, and a length of 50m along the inner street (residential road). Do you want to set up fire lanes crossing the building? A: The relevant provisions of the "Construction Regulations" and "High Regulations" consider that there is no restriction on the length of the two wings on the premise of meeting the requirements of fire fighting and evacuation. The building only needs to set up a pedestrian passageway connecting the street and the inner courtyard at the part over 80m along the street, and there is no need to set up a fire lane. In the planning of fire lanes, in addition to the relevant provisions of the "Construction Regulations" and "High Regulations", attention should also be paid toThe anterior palm of the foot is also thickened.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.Discussing the price with the landlord's intermediary, there is quite a little woman's delicacy. This can also be seen from the plan to purchase office supplies.他一开头，众太监和张家护卫下人都高声祝贺。Interpreter mode: pay attention to encapsulating changes in specific fields, support frequent changes in domain problems, express problems in specific fields into sentences under certain grammatical rules, and then construct an interpreter to interpret such sentences, thus achieving the purpose of solving problems.赵匡胤与结拜兄弟柴荣、郑恩及贺彤共同扶助郭威建立后周，遭威女婿德所不容，竟联合契丹耶律世藩杀威，荣为夺帝位，故意不加援手，威重伤而死，传帝位予柴荣。 另一方面，匡胤与好友栔傲同时爱上耶律纳兰，纳兰与贺彤则争恋匡胤，匡胤与纳兰因处于敌对关系，未能结合，纳兰伤心返回契丹，匡胤终与贺彤成亲。 荣在皇后戚戚献计下，利用匡胤与耶律安图议和，暗里派兵打契丹，二人因此渐生嫌隙，及后匡胤屡立大功，深受官民爱戴，荣恐他拥兵叛变，施计夺其兵权，荣、匡胤终正面冲突。 最后，匡胤败荣，被将领黄袍加身，拥立为帝，开国号宋，是为宋太祖。
