正警犬物证搜索是训导员指挥警犬,利用犬灵敏的嗅觉和敏锐的气味分化能力,依据特定或特异气味对特定范围进行搜索作业,从而发现或查获相关物证、发现案件线索或确定犯罪地点的警犬使用形式。是用已知物证上沾附的特定气味去求证相同气味的未知物证的一种工作方法。本文是训导员根据实际案例,结合现场勘查提取的痕迹物证,通过认真思考,提出将警犬物证搜索技术与警犬鉴别技术在现场使用中有机 相似文献

荷兰是目前世界上使用警犬进行气味鉴加较成功的国家之一。早在20世纪初荷兰警方便已开始用警犬鉴别女嫌疑人的气味。警犬鉴别技术得到了荷兰法律的认可。法庭可根据警犬对嫌疑人气味鉴别的结果对嫌疑人进行起诉。荷兰警方的警犬鉴别有三种方法。 相似文献

近年来,"警犬鉴别"这一提法,在警犬工作中,已经鲜有人提及,最近几年来也很少举办警犬气味鉴别技术培训班。是什么原因导致了我国警犬气味鉴别技术遭遇了如此大规模的"滑铁卢"呢?本文中笔者就结合我国警犬气味鉴别技术的现状,将一些有益的研究和思考总结如下,以供大家参考。一、警犬气味鉴别技术的现状警犬鉴别技术作为早期传统刑侦犬训练和使用的重要内容之一,历来受到各级公安机关的高度重视,并在公安工作中发挥了极其重要的作用。 相似文献

<正>警犬实战行为能力是犬经过系统化、规范化警用素质培养和相关科目训练后,能够达到参与和辅助警务实战工作的能力。纵观我国警犬训练与使用的发展历程,它始于刑侦工作,而后随着公安工作的实际发展,结合犬的自身生物学特性,在原有的基础上逐渐分离出其他专向用犬,并且不断呈现“专犬专训专用”的细化趋势,以适应当前警务实战需求。目前,我国警犬的专向实战行为能力培养主要包括：追踪气味、鉴别人体气味、搜索毒品、 相似文献

实战案例显示，警犬技术正朝更加专业化、精细化的方向发展，血迹搜索犬就是专业化强的犬。血迹搜索犬在命案现场中的主要作用是平面血迹、血迹气味、尸体尸块、带血痕迹物证等方面的搜索。血迹搜索犬的应用具有快速简便、易于操作的特点，其理论基础在于：犬具有不可替代的灵敏嗅觉，能对不同的气味进行分化、辨别；血迹气味具有客观性、稳定性、规律性、差异性等警犬气味作业的条件。 相似文献

一、合理使用诱惑气味的作用与意义,诱惑气味是在警犬搜爆训练中,用于增加搜索难度,提高警犬搜索能力不可或缺的训练手段。能够较好地在搜索过程中排除诱惑气味干扰,准确无误锁定嗅源客体,是检验警犬搜爆是否具备实战作业能力的重要依据。 相似文献

一、警犬应用在快递分拣点搜索的优势
犬是一种嗅觉及其灵敏的动物,在警犬掌握基本搜索能力后,建立其与目标气味的联系,即可快速应用于快递包裹的搜索.经过训练,我们发现用警犬搜索快递包裹有两大优势:
一是成型快.我们将一头警犬进行为期10天的气味联系和气味分化后,基本就具备了搜索"电诈"物资的能力,相比于研发新的高科技产品来说,可以快速训练成型并投入使用. 相似文献

In late December 1984, 1853 institutional veterinarians and small and mixed animal clinics across Canada were sent a questionnaire in order to assess the status of Dirofilaria immitis in Canada in 1984 and 35% of them responded. Veterinarians reported that 97,794 dogs were blood-tested to check for microfilariae and 1417 dogs (1.45% of those tested) were found with heartworm. Another 34 dogs were amicrofilaremic, but were diagnosed as having heartworm disease, to give the total number diagnosed in 1984 as 1451 (1.48%). Heartworm was reported from all provinces except Prince Edward Island and Newfoundland but most (1310) of the cases were in Ontario. In Quebec, 126 cases were reported mostly from west of Montreal. Heartworm was found most frequently in companion dogs over three years of age maintained mainly outdoors in rural areas. About 27% of the cases were observed with clinical signs of heartworm disease and 72% had a history of not having left Canada. Southwestern Ontario continued to be the primary focus of the infection. 相似文献

In late December 1983, 2 800 veterinarians across Canada were sent a questionnaire in order to assess the status of heartworm disease in Canada in 1983 and 26% of them responded. Veterinarians reported that 59 504 dogs were blood-tested to check for microfilariae and 771 dogs (1.30% of those tested) were found with Dirofilaria immitis. Heartworm disease was diagnosed in all provinces except New Brunswick and Newfoundland but most (733) of the cases were in Ontario. Heartworm disease was found most frequently in companion dogs over three years of age maintained mainly outdoors in rural areas. About 31% of the cases were observed with clinical signs of heartworm disease and 64% had a history of not having left Canada. Southwestern Ontario continues to be the focus of the infection and most of the dogs there had not left the province previously. 相似文献

In late November 1991, 1883 clinics in Canada were sent a questionnaire to assess the status of Dirofilaria immitis in dogs in 1991 and there was a 60.0% response. There were 344,031 dogs tested for heart-worm (HW), 627 were found infected and the prevalence of HW infection was 0.18%. There were 417 dogs with HW in Ontario, 116 in Manitoba, 38 in Quebec, 53 in British Columbia, three in Alberta, and one in Nova Scotia. In British Columbia, all of the infected dogs but one were from the Okanagan valley which, as from 1991, is a new focus of infection in Canada. Most dogs with HW had not been on preventive medication in 1990, and the prevalence among dogs tested and unprotected was 0.59%. That prevalence was considerably higher in endemic areas. Companion dogs, over three years of age and maintained primarily outdoors in rural areas, were most frequently infected. One cat was diagnosed with D. immitis and 33 dogs had Dipetalonema reconditium. 相似文献

Veterinarians reported that 137,300 dogs were blood-tested to check for microfilariae and 1210 dogs were found with heartworm. Another 36 dogs were amicrofilaremic but diagnosed with heartworm disease to give the total number diagnosed in 1985 as 1247 (0.91%). Heartworm was reported from all provinces except Prince Edward Island, Newfoundland and Saskatchewan but most (1126) of the cases were in Ontario. Southwestern Ontario continued to be the primary focus of the infection in Canada. From Quebec, 91 cases were reported mostly from and around Montreal. From Manitoba, 19 cases were reported from Winnipeg and surrounding areas. Heartworm was found most frequently in companion dogs over three years of age maintained mainly outdoors in rural areas. About 28% of the cases were observed with clinical signs of heartworm disease and 78% had a history of not having left Canada. 相似文献

In late November 1989, 1732 clinics and institutional veterinarians were sent a questionnaire to assess the status of Dirofilaria immitis, and 51.7% responded. Of 247,716 dogs tested, 394 had D. immitis microfilariae and 51 were amicrofilaremic for a total of 445 cases and heartworm prevalence of 0.17%. Most (408) of these dogs had no preventive medication and the prevalence among dogs tested and unprotected was 1.01%. That prevalence was considerably higher in endemic areas. Thirty-seven dogs with heartworm had preventive medication. Heartworm was most frequent in companion dogs over three years of age maintained outdoors in rural areas. About 75% of the cases had never left Canada, 26% had clinical signs and 125 were not treated. Heartworm was reported from British Columbia, Manitoba, Ontario, Quebec, Nova Scotia and Newfoundland, but 383 cases were in Ontario. South-western Ontario was the primary focus of infection. There were 33 cases in Quebec and 24 in Manitoba, mainly found in and around Metropolitan Montreal and Winnipeg respectively. 相似文献

Another 65 dogs were amicrofilaremic but diagnosed with heartworm disease and one was found with heartworm at necropsy to give the total number diagnosed in 1986 as 935 (0.62%). Heartworm was reported from Manitoba, New Brunswick, Ontario and Quebec, but most (810) of the cases were from Ontario. South-western Ontario continued to be the primary focus of the infection in Canada. There were 103 cases reported from Quebec, mostly from and around Montreal, and 21 cases from Manitoba, from Winnipeg and surrounding areas. Heartworm was found most frequently in companion dogs over three years of age maintained mainly outdoors in rural areas.
