中国发明的火药与火器,在14世纪经阿拉伯传入欧洲后,经过火器研制者们近两个世纪 (15世纪末至16世纪前期)的仿制和改进,制成了在构造和性能上都比明代前期火铳优越的新型枪炮。这些枪炮在构造上的根本性改变的重要方面,就是都安有照门,准星瞄准装置, 火炮两侧安有炮耳,可以对远距离的目标进行瞄准射击,自由转动炮耳,调整俯仰射角,增大了射程,提高了命中率。它具有的优点,恰恰是中国传统火炮当时存在着的缺点。随着佛郎机、鸟枪等这些西方火器实物东传到中国。火器研制者获得了新的科学技术的启示,始明 After the invention of gunpowder and firearms in China in the 14th century through Arabs in Europe, after the imitation and improvement of the firearms developers over the last two centuries (from the late 15th century to the early 16th century), they were both made in terms of structure and performance better than the Ming dynasty Pre-fire superior new guns. An important aspect of the fundamental structural changes that these guns make is that there are security guns and sight aids aimed at the guns, which are guarded on both sides of the gun for aiming and firing at long-range targets, turning the cannon ear freely and adjusting the pitch Shot angle, increase the range, improve the hit rate. It has the merit that it is precisely the shortcomings of the traditional Chinese artillery at that time. With the Buddha machine, shot guns and other Western firearms in-kind East spread to China. Firearms developers have been inspired by new science and technology
