【摘要】 陆静梅教授的课题组在长达19年的研究过程中,首次成功地研究了光学显微镜的暗差扫描摄影技术,为植纹鉴定创出一条新路,解决了尸体胃内容物极度腐烂时,不能进行封片处理的技术难题,为刑事侦查破案提供了准确、便捷的植纹光学显微镜的暗差三维扫描成像技术,获得了突破性的重要研究成果。本文采用了陆静梅教授的植纹专利技术,对采自长白山地区1700-2100m之间蕨类植物宏观形态及表观纹理结构进行了系统的分析,蕨类植物世界主要分布于热带地区,有约50属,600种。我国分布全国各地,有约27属,150种。通过光学显微镜的观察研究,将杉蔓石松(Lycopodium annotinum L.),卷柏(Selaginella tamariscina (Beauv.)Spr.),问荆(Equisetum arvense L.),蕨(P.aquilinum(L.)Kuhn),分株紫萁(Osmunda cinnamomea L.var.asiatica Fernald),猴腿蹄盖蕨(Athyrium multidentatum (Doeee)Ching)这六种代表性的蕨类植物作为主要的研究对象。实验结果显示上述六种植物的植纹特征分别为如下的几种类型:杉蔓石松Lycopodium annotinum L.的植纹(细胞壁C型);卷柏Selaginella tamariscina (Beauv.)Spr.的植纹(气孔在胞间隙缝中,保卫细胞半月形,细胞壁G型);问荆的植纹Equisetum arvense L.(细胞壁E型);分株紫萁Osmunda cinnamomea L.var.asiatica Fernald的植纹(细胞壁F型);蕨P.aquilinum(L.)Kuhn的植纹(细胞壁F型);猴腿蹄盖蕨Athyrium multidentatum (Doeee)Ching的植纹(细胞壁F型)。研究结果表明:结合蕨类植物的植纹类型以及表皮附属物类型可以对长白山地区植物进行有效的鉴别。本文讨论的几种植物都有一定的药效价值,这对以后药用植物的鉴定和分析具有一定的意义。植纹有很高的使用价值,可作为“植纹”标准比对样本,直接用于检验鉴定。这项研究可在刑事侦察中推广使用,以拓宽刑侦技术检验鉴定的范围。“植纹”鉴定研究为我国刑侦科学技术开辟了新领域,填补了国内、外空白。更多还原

【Abstract】 In the several decades of research and study, Professor Lu Jingmei led a team to complete the study of plant print. It is the first time to use the dark division scanning technique successfully. it gives us a new way to study the plant print. It solves the problem of the extremely decomposed stomach contents can not be mounted. The plant print three-dimensional(3D) optical microscopy scan-imaging technology provides exactly and conveniently investigation clues for criminal detection. It has obtained the unprecedented development.In the present study, the leaf epidermises of Pteridophyta plants in 1700-2100m of Changbai Mountain were observed with optical microscopy using the Plant Print technology. There are about 50 genera, 600 species , mainly in the tropics. There are about 27 genera, 150 species in China and they distribute all over the country. We observed and studied about 6 species of ferns from Changbai Mountain, They are, respectively, Lycopodium annotinum L.; Selaginella tamariscina (Beauv.)Spr.; Equisetum arvense L.; P.aquilinum(L.)Kuhn; Osmunda cinnamomea L.var.asiatica Fernald; Athyrium multidentatum (Doeee)Ching. The results indicated that the plant print of Lycopodium annotinum L.cell wall is type C; The plant print of Selaginella tamariscina (Beauv.)Spr. cell wall is type G; The plant print of Equisetum arvense L. cell wall is type E; The plant print of Osmunda cinnamomea L.var.asiatica Fernald.cell wall is type F; The plant print of P.aquilinum(L.)Kuhn .Cell wall is type F; The plant print of Athyrium multidentatu(Doeee)Ching. cell wall is type F . The results indicated that, Pteridophyte in Changbai Mountain could be effectively identified according to the types of Plant Print and appendages of the leaf epidermises.The results show that the plant print has practical and high value, which could be use as the standard comparisons. It is directly used for examination appraisal. The technology can be used more widely in the area of criminal detection. The study of Plant Print apparent Structural opens new realms of criminal detection. The technology is the first at home and abroad to fill the gaps in the field.更多还原
