2. 保持书写面的清洁：

定期清洁圆珠笔的书写面，以保持其良好的书写效果。当发现书写面有污渍或油墨积聚时，可以使用柔软的布或纸巾轻轻擦拭。注意不要使用尖锐的物品清洁，以免划伤书写面。 3. 正确存放： 圆珠笔应存放在干燥、阴凉的地方，避免阳光直射和潮湿环境。长时间不使用的圆珠笔应将墨水系统内的墨水排空，以防止墨水干涸堵塞笔芯。 三、翻译成英文： **Selection and Maintenance of Ballpoint Pens**

High-quality barrels are usually made of sturdy materials with a smooth surface and a comfortable grip. Additionally, check the tightness of the clip to ensure that it securely holds the pen when needed. 2. Nib and Ink: The fineness of the nib and the fluidity of the ink are crucial factors determining the writing performance of a ballpoint pen. During selection, try writing a few lines to observe if the nib is smooth and the ink flows evenly. Also, note the color and dryness of the ink to ensure satisfactory writing results. 3. Brand and Price:

Ballpoint pens from different brands vary in quality in the market. When purchasing, consider well-known or reputable brands. Do not solely rely on low prices as they often reflect the product's quality and cost. Choose a ballpoint pen with a guarantee of quality within a reasonable price range.

II. Maintenance of Ballpoint Pens 1. Avoid Dropping and Heavy Pressure: During use, avoid dropping or applying heavy pressure on ballpoint pens as it may damage the internal nib and ink system, affecting writing performance. If dropped accidentally, inspect the nib for any deformation or damage, and replace it promptly if necessary. 2.

When noticing dirt or ink buildup on the writing surface, gently wipe it using a soft cloth or paper towel. Avoid using sharp objects to clean to prevent scratching the writing surface. 3.
