1.背景受到在电视里看到的气垫船可减小阻力、增加速度的启示,联想到验证惯性定律的理想条件是没有外力,利用相似联想的迁移法,构思出这一小发明。 2.原理从气球中放出的空气在唱片和桌面之间形成了一层薄薄的气垫,起到了气垫桌的作用,大大减小了唱片与桌面间的摩擦力。
1. The background is inspired by the fact that the hovercraft seen on TV can reduce the resistance and increase the speed. It is conceived that the ideal condition for validating the law of inertia is that there is no external force. The similar association method is used to conceive this invention. 2. Principle The air released from the balloon forms a thin air cushion between the record and the desktop, which acts as an air cushion table, greatly reducing the friction between the record and the table.
