炮管壽命 的英文怎麼說
中文拼音 [bāoguǎnshòumìng]
炮管壽命
英文
barrel life-
Study of estimation method of the remaining life of gun barrel
火炮身管剩餘壽命評定方法的探討Study on assess ment of cannon barrel life by muzzle velocity of pill
彈丸初速評定火炮身管壽命研究The use of the rapid - fire revolving barrel gun successfully solves the contradiction between high firing rate, long life time and small recoil, but on the other hand brings on a new problem to naval gun fire control system
摘要速射轉管炮的使用成功地解決了射速高、壽命長、后坐力小三者之間的矛盾，但另一方面也給艦炮火控系統帶來了新的問題。In the paper, the projectile pushing process on firing is analyzed. the quantitative computational model of the projectile velocity to gun bore wear is built. finally, taking the 120mm gun for example, the relation of projectile velocity to gun bore wear is calculated, the phenomenon of trajectory peak is analyzed
分析了射擊時彈丸擠進過程，建立了彈丸初速下降量與炮膛內膛磨損量計算模型，並以某火炮為實例計算了該炮彈丸初速下降量與炮膛內膛磨損量之間變化關系，分析了彈道峰現象，為身管壽命預測提供理論依據。The special system is able to inspect and analyse the state of ablation, disfigurement of machine, bug of material and the degree of abrasion on the inner surface, which is an important instrument for make certain on remain life and shooting security of artillery body
該專用系統可對火炮身管膛內表面的燒蝕狀況、機械損傷、材質缺陷及磨損程度等疵病進行檢測與分析，是確定身管剩餘壽命及評價射擊安全性的重要手段。Thermal ablation wear is a key factor in deciding the life of a rapid - fire - gun barrel
摘要熱燒蝕磨損是決定速射火炮身管壽命的關鍵因素。The flame temperature is lower, thus giving a longer barrel life.
火焰溫度較低，因而可使炮管壽命較長。Gun tube life analysis and computation
火炮身管壽命分析與計算The outer surface temperature of barrel can be efficiently cooled down by adopting the outside cooling fluid method in a rapid - fire gun, but its effect on reducing barrel inner peak temperature and prolonging the life is limited
（ 2 ）對于速射火炮，外液冷方式可以有效降低身管外壁的溫度，但對于身管內膛溫度的降低和壽命的提高作用有限。分享友人
