解析圆珠笔的工作原理与特点 一、圆珠笔的工作原理 圆珠笔是一种常见的书写工具，它的工作原理基于笔芯中的油墨与一个或多个滚动球的相互作用。下面我们将详细介绍其工作原理。 1. 结构组成 圆珠笔主要由笔杆、笔芯、滚动球等部分组成。其中，笔芯是油墨的载体，滚动球则是在书写时与纸张接触的部分。 2. 工作过程 在书写时，我们通过施加一定的压力使滚动球与纸张接触。此时，由于滚动球的滚动，笔芯中的油墨被带出并附着在纸上，从而完成书写过程。 二、圆珠笔的特点

圆珠笔具有许多特点，使其成为人们日常生活和工作中常用的书写工具。

Analysis of the Working Principles and Characteristics of Ballpoint Pen Ballpoint pen is a common writing tool, whose working principle is based on the interaction between the ink in the refill and one or more rolling balls. Below we will introduce its working principle in detail. 1. Structural Composition A ballpoint pen is mainly composed of a pen barrel, a refill, a rolling ball, and other parts. The refill is the carrier of the ink, while the rolling ball is the part that contacts with the paper during writing. 2. Working Process When writing, we apply certain pressure to make the rolling ball contact with the paper. At this point, due to the rolling of the ball, the ink in the refill is taken out and attached to the paper, thus completing the writing process. 3. Characteristics of Ballpoint Pen Ballpoint pen has many characteristics that make it a commonly used writing tool in people's daily life and work. Firstly, its writing process is smooth and free from jamming due to the rolling of the ball. Secondly, the ink can be evenly distributed on the paper during writing, resulting in clear handwriting. Thirdly, its simple structure and strong durability of various components make it have a long service life. Additionally, the ink of a ballpoint pen also has good water resistance, oxidation resistance, and other characteristics, enabling it to maintain good writing performance in various environments.
