反馈在射击教学训练中的作用

反馈,在各项运动技能形成中,都具有极其重要的作用。同理,反馈在人民警察手枪射击教学训练中,能够有效地提高教学效果、促进学员射击技能的形成,使学员尽快掌握动作要领、纠正不足和错误的动作,从而提高动作质量、提高射击水平。     

基于全国联网的公安民警训练信息化平台的研究

在公安民警培训过程中,信息化训练管理平台的引入可以有针对性地订制公安民警培训计划,并且建立各自的培训档案,该档案既可以作为定期进行技能考核的依据,又可以作为其他方面考核的依据。有效地利用信息化技术可以大大增强公安民警的培训效果、提高公安民警培训的主动性和积极性、促进我国公安民警专业化素质的快速提高。     

谈手枪射击课中“时间量”教学法

为提高公安院校学生手枪射击的技能,以适应公安实践的需要,训练中可将体育教学中的"时间量"训练法运用进去,着重进行掏枪中的时间量训练、上膛与瞄准中的时间量训练、瞄准与击发中的时间量训练和"二快一中"的时间量训练.     

谈手枪射击训练中的教学方法

手枪射击技战术训练不是普通的课堂教学,教师除了教会学员掌握正确的手枪射击技战术技能,更重要的是培养他们坚强的意志、良好的心理素质和顽强的作风,以适应实战需要。而良好的技能、精湛的技艺只有靠平时刻苦训练取得。     

提高公安院校学员实战射击技能的方法

射击技能是公安民警所必须掌握的最基本、最重要的警务技能。如何使公安院校学员掌握牢固、精湛的射击技能并能合理应对日渐复杂的犯罪案件是公安教育改革的一项重要内容。文章结合在实际公安工作中进行射击时所面临的各种复杂环境与情境,分析了在实战射击教学中物理模拟训练与数学模拟训练的差异性,为提高公安院校学员的实战射击技能提出了相应的对策。     

射击实弹教学的心理训练

第一次进行实弹射击训练的学员普遍感到新鲜、兴奋,抑或难以消除的恐惧感,这种心态将会对射击教学质量造成一定的影响。对学员进行射击实弹教学的心理训练,将有助于消除学员的不良心理,提高技术动作的准确性,提高实弹射击成绩。     

Influence of Running on Pistol Shot Hit Patterns

In shooting scene reconstructions, risk assessment of the situation can be important for the legal system. Shooting accuracy and precision, and thus risk assessment, might be correlated with the shooter's physical movement and experience. The hit patterns of inexperienced and experienced shooters, while shooting stationary (10 shots) and in running motion (10 shots) with a semi‐automatic pistol, were compared visually (with confidence ellipses) and statistically. The results show a significant difference in precision (circumference of the hit patterns) between stationary shots and shots fired in motion for both inexperienced and experienced shooters. The decrease in precision for all shooters was significantly larger in the y‐direction than in the x‐direction. The precision of the experienced shooters is overall better than that of the inexperienced shooters. No significant change in accuracy (shift in the hit pattern center) between stationary shots and shots fired in motion can be seen for all shooters.     

Evaluation of shooting distance by AFM and FTIR/ATR analysis of GSR

The techniques of atomic force microscopy (AFM) and Fourier transform infrared attenuated total reflectance (FTIR/ATR) spectroscopy are applied to the analysis of gun-shot residue (GSR) to test their ability to determine shooting distance and discrimination of the powder manufacturers. AFM is a nondestructive technique that is capable of characterizing the shapes and size distributions of GSR particles with resolution down to less than a nanometer. This may be useful for estimation of the shooting distance. Our AFM images of GSR show that the size distribution of the particles is inversely proportional to the shooting distance. Discrimination of powder manufacturers is tested by FTIR/ATR investigation of GSR. Identifying the specific compounds in the GSR by FTIR/ATR was not possible because it is a mixture of the debris of several compounds that compose the residue. However, it is shown that the GSR from different cartridges has characteristic FTIR/ATR bands that may be useful in differentiating the powder manufacturers. It appears promising that the development of AFM and FTIR/ATR databases for various powder manufacturers may be useful in analysis and identification of GSR.     

根据霰弹丸分布图形推断射击距离的实验研究

目的 建立推断制式霰弹猎枪射击距离的数学计算公式和方法。方法 选用国产制式12号及16号猎枪,配用1号及3号猎枪弹,以1至12m距离射击实验靶纸,获得霰弹分布图形360例,将图形测量数据与实验距离进行数学理论分析。结果 建立6种不同枪弹种类推断射击距离d的计算公式,分别为12-1型(缩口)ss=-0.2+0.44d;12-1型(无缩口)ss=-0.94+0.63d;12-3型(缩口)ss=-0.59+0.52d;12-3型(无缩口)ss=-0.36+0.34d;16-1型s=-0.37+0.30d;16-3型s=-0.16+0.23d,并用Visual Basic5.0软件编制通用程序汇总软件。结论 本研究建立的方法简单实用,误差较小,可以用于推断制式猎枪的射击距离。
