Barrel from front to back gradually thickening and increase the distance between the fire door to the muzzle and bore the proportion to increase range and improve the lethality. This way is not easy to burst in the bore. In addition, also on the front sight and according to door in the gun body. increase in artillery on both sides of the gun ear, so that artillery can be mounted on artillery or gun rack above so that you can adjust the firing angle.
Although early in the thirteenth century Yefa Ming artillery, but almost all of military studies before the Ming Dynasty, did not mention the artillery targeting technology can be said to be a matter of experience to launch artillery, the natural philosophers of the Western has been Want to use mathematical formulas to describe the movement of the shells. Western scientists the mathematical knowledgeable about a simple and practical instrument, and take to enhance the precision of the mechanical operation. Thus was born the modern ballistics and gunnery.
Of course, in the mid-17th century, Western missionaries arrival and Xu Guangqi and Li algae such as believe in Catholic who will be a lot of Western books translation into Chinese. Such a to ballistics also spread to the Chinese. So during this period, there is a Sun Yuan's Derived from Western about the artillery aimed at the books at the time, but the nfl why spend so much effort to re-translate the finishing these books? that this period of translation of European artillery books, often directly to the data on the original book, but not be translated in accordance with the unit of measure used by China and the translation unit of the West also copied the original term, coupled with on that period of European countries are not unified measurement standards, thus creating great confusion. like the Ming Dynasty step five feet about 156cm circumference defined 365.25 degrees,cheap basketball jerseys, which can be different from the the definition mentioned in the book pounds of course they will be fuzzy. Imagine our artillery to get such instructions for use how and combat of the Western powers.
nfl first translation of all the units of measurement into inch size, and then inch sizes translated into international units. a unified unit of measurement. I nfl implemented in the Taoyuan Villa metric nfl According to Thomas,Phoenix Suns Jerseys, their experience and books knowledge to develop the use of gun regulations, gun-foot, from the degree and star and other instruments on such the nfl write a demanding this operation. two books became the basic textbook of the Artillery School.
Artillery improvements. Guns there are not so smooth. Nfl asking them to mounted flintlock developed nfl with this plan, almost all of them think she was crazy, they to the gun from the front-loading as Thomas said: after installed since the cannon can be mounted guns Why can not installed it?
