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 to世界会变成什么样？灵犀阁最后一位阁主到底是谁？被释放的火领主会做什么？灵犀阁会怎么样？女王和黎灰会得到灵犀之力吗，时希封印解除，辛灵冰公主会回来吗？ 随着时间的推移，渐渐发现爷爷的死并非意外……《可以跟你回家吗》是一档非虚构类都市群像微纪录片，节目全程真实记录，没有预设、没有煽情，在城市中寻找一眼对视的陌生面孔，帮助他解决眼前的小麻烦，在征得其同意、保护其隐私的前提下，用镜头和语言打开他们的家门与心门，与每一个有趣的灵魂深度对话，探索他们褪去社会角色后的真实人生。董佳音和夏鸣涛结婚三年都没有要孩子。董佳音是电视台社会新闻节目的制作人，夏鸣涛是妇产医院的主任医生，两人的事业都正处于一个上升期，无暇顾及生孩子的事。夏鸣涛的母亲见还抱不上孙子，一急之下从老家赶来，亲自监督小两口要孩子。结果婆媳之间频繁产生摩擦，懂事的董佳音体谅婆婆抱孙心切的心情，委曲求全，而夏鸣涛夹在中间，既心疼妻子，又顾念老母，左右为难。 蓝氏贸易的老板蓝天和妻子徐雅莉夫妻十年，伉俪情深。当年蓝天因打架伤人而坐牢，刑满释放，徐雅莉不惜跟娘家彻底断绝关系而嫁给了蓝天，两人一无所有地来到当地，患难与共，历尽艰辛，终于有了现在的财富和地位。徐雅莉很爱孩子，蓝天就想给她一个孩子，无奈却检查出不孕。痛苦的蓝天在夏鸣涛的帮助下进行各种治疗。 董佳音在一次采访中救助一个早产孕妇，结识了刚刚回国到妇产医院工作的周一敏。周一敏高超的医术令董佳音钦佩。周一敏其实是夏鸣涛原来大学时期的恋人，但是周一敏在毕业的时候却因为贪慕虚荣，抛弃夏鸣涛，远嫁国外。但是周一敏的婚姻并不幸福，她又被丈夫抛弃，感情遭Browser plug-in to help complete file upload. Depending on the browser, the plug-in type may be ActiveObject or WebkitPlugin. Upload is an asynchronous process, so the control will constantly call a global function provided by javascript, window.external.upload, to inform javascript of the current upload progress. The control will insert the current file state into window.external.upload as the parameter state. A complete upload plug-in cannot be provided here. SetTimeout will be simply used to simulate the upload progress of the file. The window.external.upload function is only responsible for printing some logs in this example:Does the code contain cross-descriptions or data dictionaries to describe how the program accesses variables and constants
