Dermoscopic evaluation of normal canine skin with a handheld dermoscope
Veterinary Dermatology, Volume 36, Issue 5, Page 593-601, October 2025.Background – Dermoscopy is a noninvasive diagnostic tool that provides a magnified view of skin structures. While dermoscopy is described for certain canine dermatological diseases, large‐scale studies evaluating normal skin are lacking. Hypothesis/Objective – This study aimed to correlate dermoscopic findings with histopathological results in healthy ...

Shiyou jixie, 2012 采用光学显微镜、X射线衍射仪（XRD）、扫描电镜（SEM）和显微硬度计，研究了镍基合金等离子弧堆焊层的组织和性能。堆焊的基材为X65管线钢，焊丝是ERNiCrMo-3。研究结果表明，堆焊层由柱状晶和共晶组织组成，堆焊层中的柱状晶为γ固溶体，共晶组织为γ固溶体和Laves 相(富含Mo、Nb)；由腐蚀电化学测试可知，堆焊层的耐蚀性能随着堆焊电流的增大而减弱；氢致开裂试验结果表明，堆焊电流越大，越容易发生氢致裂纹；显微硬度测试结果表明，由基体至堆焊层显微硬度先升高后下降，熔合区硬度最高，可达310 HV以上。
