圆珠笔的书写原理及结构 一、书写原理 圆珠笔是一种利用球珠与纸面接触产生摩擦，进而通过墨水或油墨在纸上形成字迹的书写工具。其工作原理主要基于笔尖的球珠，以及球珠内的墨水或油墨的供应系统。 二、结构 圆珠笔主要由笔杆、笔尖、球珠、墨水或油墨供应系统等部分组成。 1. 笔杆：笔杆是圆珠笔的主体部分，通常由塑料或金属制成，负责支撑和固定其他部分。 2. 笔尖：笔尖是圆珠笔的书写部分，由一个球形的珠子（即球珠）组成。这个球珠由耐磨的材料制成，能够在纸面上顺畅滚动。 3. 球珠：球珠是圆珠笔的关键部分，它通过与纸面的接触和滚动，将墨水或油墨从供应系统输送到纸面上，形成字迹。

4. 墨水或油墨供应系统：这个系统负责为球珠提供墨水或油墨。它通常包括一个储墨器和一个输送管道。储墨器储存了大量的墨水或油墨，而输送管道则将墨水或油墨输送到球珠处。

三、英文翻译 The Writing Mechanism and Structure of Ballpoint Pen

I. Writing Mechanism Ballpoint pen is a writing tool that uses the friction between a ball and the paper surface to generate ink or oil-based ink, thereby forming characters on the paper. Its working mechanism mainly relies on the ball at the tip of the pen, as well as the supply system of ink or oil-based ink within the ball. II. Structure A ballpoint pen is mainly composed of a barrel, a tip, a ball, and an ink or oil-based ink supply system. 1. Barrel: The barrel is the main part of the ballpoint pen, usually made of plastic or metal, supporting and fixing the other parts. 2. Tip: The tip is the writing part of the ballpoint pen, consisting of a spherical ball. This ball is made of wear-resistant material and can roll smoothly on the paper surface.

3. Ball: The ball is a key part of the ballpoint pen. It delivers the ink or oil-based ink from the supply system to the paper surface through contact and rolling, forming characters.

4. Ink or Oil-Based Ink Supply System: This system is responsible for providing ink or oil-based ink to the ball. It usually includes an ink reservoir and a delivery tube. The ink reservoir stores a large amount of ink or oil-based ink, while the delivery tube transports the ink or oil-based ink to the ball. 以上就是圆珠笔的书写原理及结构的相关介绍。
