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两人就在附近找了家酒楼，要了间雅间，点了几个菜，浅酌慢饮起来。原創戲劇《親愛的亞當》由陳慧瑛製作、金獎導演廖士涵執導，是首部以「基因編輯工程」為主題的電視作品，將深入探討「基因編輯是一種愛，還是一種犯罪」，胡宇威詮釋從出生就注定不平凡，擁有通過基因編輯的完美人設，曾沛慈則扮演痛恨基因編輯被掌握在權貴手上的生技專家。孫可芳及資深演員周丹薇也都參與演出。　　张瑶饰演的高贝贝找到王彩玲，她自称身患绝症，唯一的心愿就是可以参加全国歌手大赛并获奖。在北京求职多次碰壁已经让王彩玲深深失望，同时为了帮助高贝贝，王彩玲放弃了进京的梦想，将这笔金钱用来资助后者打通关系。却没想到，自己的好心面对的是一场精心策划的谎言。RF Front End Design Challenges
