The Barrett Model 98B rifle represents a slight departure from the earlier company's profile, as it is chambered for less powerful, but very accurate .338 Lapua Magnum ammunition, which was sepcially designed for long-range sniper and target shooting.

巴雷特98B型步枪是由前公司的文件略有不同，因为它是不那么强大的鹦鹉螺，但非常精确的0.338拉普尔万能弹药，这是sepcially远距离狙击射击和目标设计。

To avoid too much public attention,your non concealable M4 ASSAULT RIFLE will be placed in a container at the premises by the Agecncy.

为了避免过于引人注意，你不能携带M4突击步枪。我们将会提前把它放置在一个预先设置好的箱子内。

Eugene Stoner (the designer of the M16 rifle and then a mastermind of the innovative arms-making company Ares Inc.) developed an idea of the easily concealable submachine gun in the early 1980s.

尤金斯托纳（设计者的 M16步枪，然后一个创新的武器策划制作公司阿瑞斯公司）开发了80年代初一个易于隐藏冲锋枪的想法。

The rifle was initially fielded with a wooden stock, which was later replaced with a fiberglass stock.

Grampa is trying to teach Cody (or Jody, or Brody, or whatever crap name the kid has) how to shoot with a 1950's era Lakefield or Cooey .22 rifle and an empty tin can lying 10m away on the ground.

爷爷试图教会Cody（或Jody，或Brody，或者其他什么狗屁名字）怎么用一支1950年产的Lakefield或者Cooey的。22步枪去射击一个10米开外的罐头。

One theory was that rifle fire from the Housatonic had put a hole in the Hunley, flooding it.

有种说法趁，从HOUSATONIC号发散出来的火焰射穿了杭力号，使其进水。

The latter theory was laid to rest in 1970 when the Hunley was found on the bottom about a mile from the Housatonic. The Hunley was raised in 2000 and brought to shore for analysis and preservation. Its crew was interred with full military honors in 2004. In October 2008, archaeologists finally confirmed that the crew had not tried to use the submarine's water pumps, therefore there was no reason to believe that the hull of the vessel had been pierced by rifle fire.

直到1970年人们在离蒙萨通尼克号大约一公里的海底发现了汉利号，后一种猜想才不攻自破。2000年时人们把汉利号打捞到海岸上，用作分析和保藏。2004年时，人们用完整的军葬礼埋葬了汉利号全体船员。2008年10月时，考古学家最终得到定论：船员并没有试图使用潜水艇的抽水机，因此可以推断船体并没有被步枪打穿。

Incurrent research, aiming at the rupture problem engendered in the shooting process of acertain 5.56mm automatic rifle, the strain and stress distributions on the cartridge caseunder the action of axial pull have been analyzed. Based on the theories of elastic-plasticmechanics and contact mechanics, a mathematic and physical model of the cartridge-caseand chamber system has been set up; and based on the platform of the general softwarepackage APDL of ANSYS for finite element analysis, a parameterized model of thecartridge-case and chamber system has also been established. The method for nonlinearFEA has been adopted to analyze the stress distribution on the entire cartridge-case andchamber system, and the method of contact element has been employed to investigate thecontact stress between the cartridge case and chamber, and then the influences of frictioncoefficient and locking space on the static and dynamic stress and strain response of thecartridge case and chamber to the action of power gas have also been discussed. On thebasis of a lot of numerical tests, a kind of element Plane13, which is concentrated incoupled computation of heat and construction, has been used finally to simulate thetransient response of the cartridge-case and chamber system to the power gas. Throughloading the temporary thermal characteristics of explosive gas in the procedure of emulate, the corresponding transient thermal stress distributed on the entire system under thecombined load of transient thermal stress and transient pressure has been obtained. Owingto these comprehensive considerations, the numerical results obtained in this paperrepresent the actual situations comparatively exactly.
