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: This attribute needs to configure the value of taskAffinity in the AndroidManifest.xml file of the target activity to be started "must be different from the package name of the startActivity sender activity, and taskAffinity can be omitted if jumping to another App", which will press the activity into the taskAffinity where the newly marked Affinity exists.张天聪作为中国第一代航天员，刻苦训练、专业技术过硬，但仍然在神舟七号宇航员选拔中失利。面对昔日战友的转岗离去和自身年龄偏大等种种压力，张天聪没有放弃飞天梦想，毅然选择继续留在航天员大队，成为谢朝阳、王立三、周晓苏等新一代航天员的训练教官。Output:Jack Huston饰演幕后主脑Eric Rudolph，于2003年被捕。而Cameron Britton饰演Richard Jewell，他当年发现其中一个炸弹并疏散观众，但其后被FBI定为头号嫌疑犯，因此他成了媒体轰炸的对象。其他主演有Judith Light、Gethin Anthony及Kelly Jenrette。Flowers not only attract pollinators with color and smell, but also quietly guide insects who are too shy to know what to do because they land on flowers for the first time. There will be a white route on the petals of grassland geranium to guide insects into the center of flowers and find nectar. In this process, the wings of insects will be more or less glued with precious pollen of stamens. The flowers of alpine Pulsatilla and strawberry flowers have white petals on the outside and yellow stamens in the middle. This change in color depth will highlight the stamens and allow insects to fly to the middle of the flowers without hesitation.
