利用扫描电子显微镜检验微量物证形貌

摘要

In criminal cases, it is so hard to find trace evidence, but they exist everywhere objectively. Scanning electron microscope with the characteristics of high magnification, high resolution and high sensitivity is helpful for observing and inspecting line trace, fiber, pollen and other trace evidence. The result can provide a valuable basis for the detection of the case.%在刑事案件中，微量物质微小，不宜被发现，而又客观存在，本文中利用扫描电子显微镜高放大率、高分辨率、高灵敏度的特点分别对弹壳线条痕迹、纤维、花粉等微量物证的形态进行检验。其结果能为案件侦破提供有价值依据。
