1.教室室内环境：室内综合环境的好坏与人们的身心健康息息相关。为了避免

1. classroom indoor environment: the quality of people's physical and mental health is closely related to the indoor environment integrated. In order to avoid outdoor light and generating a blackboard glare reflected light curtains, interior light shade uniformity, classrooms distal end of the long side window at the board 1.3 m, the wall between the window width of 1.2 m. Blackboard classroom walls and interior walls on both sides of the traditional practice of white latex paint, feel clean and fresh, in essence, does not meet the eye health, the reflectivity of white walls is greater than 0.8, more dazzling, eye if a long time by bright light stimulation, the formation of myopia, astigmatism and so on. The degree of absorption and reflection of green and blue light is moderate, the human nervous system, cerebral cortex and retina stimulation are no adverse reactions. Accordingly, this design uses light green blackboard spacer wall paint. <br>2. Evacuation: fire exit door opening width of not less than 1000mm. One class classroom doorway width of not less than 1500mm. And teaching space and its ancillary buildings should set the threshold, more open design stairwell convenient. The project bench width of 1.4 m (0.6 m + 0.6 m + 0.2 m). <br>3. The design of the staircase between. 20 each class 1000, two staircases, the exit width 2.2 m, to meet the requirements of the evacuation. At the same time the school also strengthened the management measures during the break by 10 minutes during each class. Requirements should not be concentrated in the side of the stairs to evacuate, otherwise easily lead to abortion is highly concentrated - because we used to evacuate from the nearest stairway access. If you do not follow the flight of stairs modular design, widened more than about 0.3 meters, it is possible to have the students down the stairs sideways congestion, stampede took place under such. Looks spacious staircase becomes widened, but the waste of land resources and increased construction costs. Therefore, the design should be evacuated from the viewpoint of the overall layout, to limit and control the total area of each layer. 

1.教室室内环境：室内综合环境的好坏与人们的身心健康息息相关。为了避免室外强光产生黑板眩光和光幕反射，室内光线明暗均匀，教室前端黑板处侧窗端长为1.3米，窗间墙宽度为1.2米。黑板两侧墙面以及教室室内墙壁传统作法为白色乳胶漆，感觉干净清爽，实质是不符合用眼卫生，白色墙面的反射率大于0.8，比较刺眼，眼睛如果长时间受到强光的刺激，会形成近视眼、散光等。而绿色和青色对光的吸收和反射的程度适中，对人的神经系统，大脑皮层和视网膜都无不良刺激反应。因此，本次设计黑板侧墙采用淡绿色乳胶漆墙面。 <br> 2.安全疏散：安全出口的门洞宽度不应小于1000mm。合班教室的门洞宽度不应小于1500mm。 并且教学用房及其附属用房不宜设置门槛，楼梯间的设计更开阔便捷。本工程梯段宽度为1.4米（0.6米+0.6米+0.2米）。 <br> 3.楼梯间的设计。每层20班1000人，两个疏散楼梯，疏散宽度2.2米,满足疏散要求。同时学校也加强了管理措施，课间休息按每层时10分钟下课。要求不得集中在一侧楼梯间疏散，否则容易导致人流高度集中-因为大家习惯从距离最近的楼梯通行疏散。如果楼梯段不按模数设计，多加宽0.3米左右，就有可能会有学生侧身拥挤下楼，踩踏事件就是这样发生的。看起来楼梯加宽变得宽敞了，可是浪费了土地资源和加大了建设成本。所以设计应该从总体布局考虑疏散，从每层总面积来限制和控制。 

1. Classroom indoor environment: the quality of indoor comprehensive environment is closely related to people's physical and mental health. In order to avoid the glare of blackboard and the reflection of light curtain caused by the strong light outside, the indoor light is even, the side window end at the blackboard at the front of the classroom is 1.3m long, and the width of the wall between the windows is 1.2m. The traditional method of the walls on both sides of the blackboard and the indoor walls of the classroom is white emulsion paint, which feels clean and fresh. In essence, it does not conform to the eye hygiene. The reflectivity of the white wall is more than 0.8, which is rather dazzling. If the eyes are stimulated by strong light for a long time, myopia and astigmatism will be formed. However, green and cyan have moderate absorption and reflection of light, and have no adverse effects on human nervous system, cerebral cortex and retina. Therefore, the side wall of blackboard in this design adopts light green emulsion paint.  <br>2. Safe evacuation: the width of the door opening of the emergency exit shall not be less than 1000mm. The width of the door opening of the classroom should not be less than 1500mm. Moreover, the threshold should not be set for the teaching room and its auxiliary rooms, and the design of the staircase is more open and convenient. The ladder section width of the project is 1.4m (0.6m + 0.6m + 0.2m).  <br>3. Design of staircase. Each floor has 20 shifts with 1000 people, two evacuation stairs, and the evacuation width is 2.2M, meeting the evacuation requirements. At the same time, the school has also strengthened management measures, and class breaks are 10 minutes per floor. It is required not to concentrate on one side of the stairwell for evacuation, otherwise it is easy to cause high concentration of people flow - because people are used to evacuation from the nearest stairway. If the stair section is not designed according to the module and widened by about 0.3m, there may be students coming down the stairs in a crowded way. This is how the stampede happened. It seems that the widening of stairs becomes spacious, but it wastes land resources and increases the construction cost. So the design should consider evacuation from the overall layout, and limit and control from the total area of each floor.<br>
