假期打工,农民工兄弟和我谈支楼梯模板的话题,从他们那里学到了不少知识,闲暇时认真地观察了楼梯的侧面,并进行了初步的探究,发现其中蕴含着不少有价值的数学信息,现提出一二,与大家分享。首先,数学思想方法。楼梯的建造蕴含着转化思想——化直为斜(曲)。其次,知识。同一楼梯的各个梯段,其楼梯踏步高度、宽度尺寸应该是相同的。楼梯踏步高度与宽度之比就是楼梯的梯度。就成人而言,楼梯踏步板的最小宽度应为240mm,舒适的宽度应为300mm左右。踏步 Holiday workers, migrant workers brothers and I talk about the stairs template support topics learned from them a lot of knowledge, spare time carefully observed the side of the stairs, and conducted a preliminary exploration and found that contains a lot of valuable Mathematical information is now presented one or two, to share with you. First of all, mathematical thinking method. The construction of the stairs implies the idea of ​​transformation - straight into oblique (music). Second, knowledge. The same staircase of the various steps, the staircase height, width size should be the same. Staircase height and width ratio is the gradient of the stairs. For adults, the minimum width of the stair treads should be 240mm and the comfortable width should be around 300mm. Steps
