只要你稍微注意一下就会发现:小型汽车的前窗玻璃都是倾斜的(如图1),这样的装置除了能使汽车具有外形美观,行驶时空气阻力小等优点外,在光学成像方面还能保证驾驶员看清前方的人和物,避免车内的人或物径汽车前窗玻璃反射所成的像影响驾驶员的视线,从而避免交通事故的发生。 As long as you take a closer look, you will find that the front windows of small cars are tilted (as shown in Figure 1). Such devices not only enable the car to have a beautiful appearance, but also have advantages such as low air resistance during driving, as well as optical imaging. It can ensure that the driver can see clearly the people and things in front of him and avoid the reflection of the driver’s eyes caused by the reflection of the front window glass of the person or the track in the car, thereby avoiding the occurrence of traffic accidents.
