退膛 的英文怎麼說
中文拼音 [tuìtáng]
退膛
英文
de-arm-
If we take out several measuring points along the bore axis and work out the amount of bore wearing, we can consult and calculate the muzzle velocity reduction of the piece by reference of the curve board
沿膛軸方向取若干個測點，當測出各點的炮膛磨損量后，即可從曲線板中查取計算出火炮的初速減退量。We must stand tall and not retreat
我們必須挺起胸膛不要退卻The results proved that : ( 1 ) because of the material ' s difference of primer - 9 and primer - 5, the maximum stress of primer - 5 is larger than primer - 9 but the maximum displacement is smaller than primer - 9. ( 2 ) because of the unrenewable shape changing of primer - 9 after impacting by the pin, it will cracking under high pressure more easily. so, the paper give the suggestion that the designer should decrease the depth of impacting by pin in the case of the primer be fired successfully
對底- 9底火、底部被擊針撞擊后的第- 9底火和底- 5底火在膛壓作用下分別進行了有限元數值分析，計算表明： （ 1 ）底- 5底火底部擊針撞擊部位為火帽座，其材料為鋼帶，底- 9底部承受撞擊部位為底火體，其材料為冷拉退火圓鋼，由於材料強度不同，承受壓力能力和變形能力不同：雖然在膛壓作用過程中底- 5底火的最大應力值比底- 9底火的大，但底- 5底火的最大位移量卻比底- 9底火的小得多。As for one specific gun ammunition system, by use of the established mathematical models the curve of the bore wearing, the muzzle velocity reduction related to that kind of curve and the weight coefficient at each section of that curve can be simulated
對于某一火炮彈藥系統，利用建立的數學模型可模擬出炮膛磨損曲線及每一條曲線所對應的初速減退量、曲線上各段的權重系數。Having proceeded from analyzing the bore wearing and erosion by application of the new method, the mathematical model of simulating the law of the bore wearing as well as that of the relationship between the law of the bore wearing and the muzzle velocity reduction have been established
新方法從分析炮膛磨損燒蝕入手，建立了模擬炮膛磨損規律的數學模型和炮膛磨損規律與火炮初速減退量關系的數學模型。On the similitude artillery, 7 items of shooting tests were proceeded. these items included : muzzle velocity of projectile, pressure of gases, recoil force, efficiency of muzzle brake, muzzle shockwave, dynamic stress, stability
在模型炮上進行了7個射擊實驗項目，實驗項目包括：初速、膛壓、后坐阻力、炮口制退器效率、炮口沖擊波、動態應力、穩定性。分享友人
