我们看到的电梯，十有八九用的都是不锈钢，而且还是做了镜面效果。其中一个很重要的原因就是不锈钢材料性价比高，价格不高而且实用！另外还有一个原因，了解一种原理叫作“平面镜成像原理”，也就是当电梯里选择使用镜面不锈钢的时候，由于“平面镜成像原理”的作用，人看见镜子里的“自己”，在视觉上会感觉自己与镜子里“自己”的距离会拉长，电梯里那么狭小的空间，就因为在这一视觉效果下，显得没那么“局促”；而设计师在此条件下，为了美观，会使用有颜色（电镀工艺）、有图案（蚀刻工艺）的不锈钢镜面板，这样既能保持电梯的美观，又能顾及每位乘客的搭乘感受，还能考虑到电梯材料的成本，可谓一举三得。这就能解释为什么电梯里用的材料，多数都是用不锈钢镜面板了。

The elevator we see, nine out of ten, are stainless steel, and still do a mirror effect.One of the very important reasons is that the stainless steel materials are cost-effective, the price is not high and practical!There is also another reason why, Understanding one principle is called the "plane mirror imaging principle.", That is, when the elevator uses stainless steel with a mirror, Due to the role of the "plane mirror imaging principle", One sees the "self" in the mirror, Visually, you feel the distance from "yourself" in the mirror, That small space in the elevator, Because, under this visual effect, It seems less "cramped"; And the designer is under this condition, For the beauty, Stainless steel mirror plates with color (plating process) and pattern (etching process) will be used, This can keep the appearance of the elevator, It can also accommodate each passenger's ride experience, It can also consider the cost of the elevator materials, Kill three birds with one stone.This explains why most of the materials used in the elevator are made with stainless steel mirror plates.
