生词：steadfastly adv.坚定地；piston-filling 活塞上墨系统（如现产146、149）
Piston n.活塞 uneven adj.不稳定的，不均匀的
Montblanc had almost alone among German manufacturers, steadfastly refused to adopt the piston-filling system. During the 1920s their engineers were worried that ink would leak out through the cork piston drying out or due to body heat expanding the barrel and creating a gap between the piston and barrel wall. They were also concerned that piston fillers could‘sweat’ due to uneven ink pressure. By 1934 all these doubts had been overcome and a range of piston fillers and a new patented push button pencil, the Pix were launched.
在德国制造商中，几乎只有万宝龙公司坚定地拒绝采用活塞式注墨系统。在20世纪20年代，他们的工程师们担心墨水会因为软木活塞的干燥或由于身体的热量使枪管膨胀，在活塞和枪管壁之间产生间隙而漏出。他们还担心，由于墨水压力不均，活塞填料会 "出汗"。到1934年，所有这些疑虑都被克服了，一系列的活塞式填充器和一种新的专利按钮铅笔Pix被推出。
