The drawback is the very close tolerances necessary in the linkage system to achieve proper timing, which increases the cost of the weapon, and considering the relatively low power of the 9x19 ammunition used in this gun (compared to original Lmg 25 machine gun that fired full-power 7.5x55 cartridges) it appears to be a gross engineering over-kill for a submachine gun.

其缺点是非常密切的联系，公差在系统实现适当的时间，从而增加了武器所必需的费用，并考虑在这枪支弹药使用的9x19功耗相对较低（相比原来的轻机枪25机枪的锅炉全部功率7.5x55墨盒）这似乎是一种严重的工程超额1冲锋枪杀死。

Applying combined method of quantitative analysis and qualitative analysis, on the basis of on ago research fruit, this paper firstly analyses main factors that affect the safe distance from friendly force to target for tank gun overhead firing systemically. Based on that, this paper builds math model of calculating the safe distance from friendly force to target separately aiming to the difference of tank gun overhead firing in plane and undulate terrain. At last, through applying Mathematica soft, this paper presents the safe distance from friendly force to target for a tank gun overhead firing used APFSDS, HEAT and HESH, combined qualitative analysis.

采用定量分析和定性分析相结合的方法，在以往研究成果的基础上，首先系统地分析并提出了影响坦克炮超越射击时友军至目标安全距离的主要因素；以此为基础，针对平坦地形和起伏地形上坦克炮超越射击的不同情况，分别建立了确定友军至目标安全距离的数学模型；最后通过运用Mathematica软件进行定量计算，并结合定性分析，提出了某型坦克炮使用尾翼稳定脱壳穿甲弹、空心装药破甲弹和杀伤爆破榴弹进行超越射击时友军至目标的安全距离。

The action mechanism of the stun gun is analyzed in detail and the scheme design of the stun gun system is completed. With the SolidWorks software, three-dimensional model of the system has been constructed. The characteristics of the interior ballistics of the proposed scheme of stun gun are analyzed and the corresponding interior ballistics model is proposed. The numerical computation of the interior ballistics is also conducted. According to the functions of the electrical module ,the circuit is designed and the security and reliability of the system is analyzed. At last, the test scheme of the system is proposed and some experiments are carried out which validate the feasibility of the designed system.

PstK/37炮 The 25 PstK/37 "Canon leger de 25 antichar SA-L mle 1937" In the early 1930s, when the majority of tanks were still light tanks, a new 25 mm AT-gun was designed for the French Army. This new gun, which was designated as "Canon leger de 25 antichar SA-L mle 1934" became later on the standard AT-gun of the French Army. It was produced by Hotchkiss.

在30年代早期，世界各国大数坦克仍然是轻型坦克，法国陆军设计了一种新型25毫米反坦克炮（法国人啊怎么不长远打算一下--译注）称之为"Canon leger de 25 antichar SA-L mle 1934"变成了法军的标准反坦克炮，从Hotchkiss机枪演变而来。

In the document requests clearly, this system's some functions: If the arms locker or the ball medicine-chest are destructed contrary opening, this system auto-alarm; The police overtime will use the gun, the system to send the short note automatically to the police handset on, the reminder will return the gun; If this police returns the guns not on time, then after certain time limit, the information automatic transmission sub-bureau "110" the warning center,"110" will supervise it by the sub-bureau to return the gun as soon as possible; If the sub-bureau "110" has not processed in the scheduled time, the city bureau "110", the city bureau public security branch, the supervisor team will simultaneously receive the alarm message.
