圆珠笔是一种常见的书写工具，它的工作原理依赖于笔芯内部的油墨以及一个球状的小珠子。在书写时，这个球珠会与纸张接触，将油墨从笔芯中带出，并附着在纸上，形成文字或图案。 二、构造 圆珠笔主要由笔杆、笔芯、油墨、圆珠等部分组成。 1. 笔杆：笔杆是圆珠笔的外壳，通常由塑料或金属制成，用于保护内部的构造并使笔具有良好的握感。 2. 笔芯：笔芯是圆珠笔的核心部分，负责存储油墨并带动圆珠。笔芯的材质通常为一种特制的油墨容器。 3. 油墨：油墨是圆珠笔书写的介质，通过毛细管作用，将油墨输送到圆珠。 4. 圆珠：圆珠是圆珠笔的关键部件，通常由硬度较高的材料制成，如碳化钨等。它能够在书写时与纸张接触并带出油墨。 三、翻译成英文 Working Principle and Structure of Ballpoint Pen I. Working Principle Ballpoint pen is a common writing tool that relies on the ink inside the refill and a spherical ball for its operation. During writing, this ball contacts with the paper, bringing out the ink from the refill and attaches it to the paper, forming words or patterns. II. Structure The ballpoint pen is mainly composed of the barrel, refill, ink, and ball. 1. Barrel: The barrel is the outer shell of the ballpoint pen, usually made of plastic or metal, which protects the internal structure and provides a good grip for the user. 2. Refill: The refill is the core part of the ballpoint pen, responsible for storing the ink and driving the ball. The material of the refill is usually a special ink container. 3. Ink: The ink is the medium for writing with a ballpoint pen, which is transported to the ball through capillary action. 4. Ball: The ball is a key component of the ballpoint pen, usually made of a material with high hardness, such as tungsten carbide. It can contact with the paper during writing and bring out the ink.
