1.
Aiming at preventing automatic firing accident of sliding wedge breechblock of ground gun, on the basis of the dint analysis to the percussion mechanism, the disquisition advances and demonstrates the conclusion that seriously abrasion of percussion mechanism is the main cause of automatic firing.
以如何预防楔式炮闩地面火炮自动击发事故为目的,从击发机受力分析入手,提出并论证了击发机严重磨损是造成自动击发主要原因的论点;通过计算与实验求出了部分火炮炮闩安全极限磨损角;制定了预防自动击发事故的应对措施。

闭气
water tight
biqi闭气(water tight)在堵口工程合龙后,采取阻水断流措施,阻止缝隙漏水。 用立堵法合龙,当合龙绿尚未蛰实,坝身仍然漏水,坝后翻花不止,大小远近不一,应辨明是底漏还是腰漏,如是底漏,说明绿体尚未到底,比较严重。闭气方法,一般有:①在正坝堵合后,除合龙蹄上加压土外,于口门坝前加修绿工,称为关门端。然后抛袋土及加修土俄,使之闭气;②双坝合龙时,用边坝合龙闭气,在正坝与边坝之间,用袋土及粘土填筑土柜,边坝之后再加后战,阻止透水;③修筑养水盆,即在坝后修筑围堤一道,把门口冲深的潭坑围起来,用以积蓄坝后渗水,抬高坝后水位与大河相平,即可闭气。对平堵的口门,因抛石渗漏严重,须采用①、②两种闭气办法,截堵渗流。(徐福龄)
