所谓圆珠笔,也就是一种笔尖上装着用铬钢或不锈钢制成的坚硬小球的笔。书写时,小球一转动,就使笔杆中的浆糊状油性墨水顺着笔尖带沟的夹具渗出来。它是1888年由美国的约翰·劳德发明的。他为了寻找可以在包装纸、木板以及表面粗糙的东西上做记号的好办法,做了种种尝试之后,终于发明了在笔尖上安装旋转珠的笔。但他最初发明的笔,用了多少墨水,就有多少空气进入笔杆,因此有从笔杆的眼儿里漏墨水的缺点。 1941年,匈牙利的新闻记者拉兹罗·比罗曾对这种笔加以改进。他于1943年流亡到布宜诺斯艾利斯以后,仍继续进行研究。最后他公布的研究结果是:应用毛细现象的原理,在细管中,注入浓稠的圆珠笔墨水,这样,就可以避免墨水流出。第二次世界 The so-called ball-point pen, which is a kind of tip with a hard ball made of chrome steel or stainless steel pen. Writing, the ball rotation, the pen in the paste-like oily ink along the nib with the ditch fixture seeping. It was invented in 1888 by John Lauder in the United States. After trying his best to find a good way to mark the wrapping paper, the planks, and the rough surface, he finally invented a pen with a rotating ball on the nib. But how much of the ink he originally invented, how much ink he used, and how much air had entered the pen, had the disadvantage of missing ink from the pen’s eye. In 1941, Hungary’s journalist Lazaro Biro improved the pen. He went on to study in Buenos Aires in 1943. Finally, he announced the results of the study are: the principle of the capillary phenomenon, in the thin tube, into the thick ball-point pen ink, so that you can avoid the ink outflow. Second world
