黑板的发展历程
The Development History of Blackboards








人类的交际方式只有两种,一种是口语交流,一种是书面交流,,而我们在学校使用的一种东西结合了这两种方式,那就是黑板,我们都知道黑板,可又有谁只知道黑板的发展历程,下面就由自动餐桌椅生产厂家给大家说一说黑板的发展历程。1、代黑板就是以木材、水泥、玻璃等材质做成的写字类黑板。 2、第二代响应环保要求,使用的是制材料的白板,属于无尘类黑板。
There are only two ways of human communication, one is oral communication and the other is written communication. However, one thing we use in school combines these two methods, which is the blackboard. We all know about blackboards, but who only knows about the development process of blackboards? Below, the manufacturer of automatic dining tables and chairs will tell you about the development process of blackboards. 1. Daichalkboard is a writing blackboard made of materials such as wood, cement, and glass. 2. The second generation responds to environmental protection requirements by using white boards made of materials, which belong to the dust-free category of blackboards.






3、第三代利用现在的科技,在黑板上展示出图文,如投影,电子显示屏等。也就是我们所说的影音类黑板。 4、第四代是电脑与黑板的互通互联,如红外式电子白板,激光式电子白板等都属于交互类黑板。 5、第五代集中解决了交互式电子白板所需要的外设硬件配套使用,如:电视型黑板,电脑型黑板等,属于显像类黑板。 3、第三代利用现在的科技,在黑板上展示出图文,如投影,电子显示屏等。也就是我们所说的影音类黑板。
3. The third generation utilizes current technology to display graphics and text on the blackboard, such as projectors and electronic display screens. That is what we call an audiovisual blackboard. 4. The fourth generation is the interconnection between computers and blackboards, such as infrared electronic whiteboards, laser electronic whiteboards, etc., which belong to interactive blackboards. 5. The fifth generation focuses on solving the peripheral hardware matching needs of interactive electronic whiteboards, such as TV type blackboards, computer type blackboards, etc. It belongs to the category of imaging blackboards. 3.

Storage space: Most electric desks used by children nowadays have a double bucket structure, with a hook on the side. It sounds like there is quite a lot of usable space, but in reality, the second floor is very shallow and can only hold some miscellaneous items. Moreover, the hook on the side is located next to the aisle, which affects the walking of students.
