Objective: To evaluate the efficacy of He-Ne laser in combination with topical clindamycin in the treatment of AV at 108 Military Central Hospital from Oct 2015 to Aug 2016. Subjects and Methods: 61 patients with AV were divided into 2 groups: Group 1: 31 patients were treated with He-Ne laser in combination with topical Clindamycin, Group 2: 30 patients were only treated with topical clindamycin. Laser HE-NE was applied 2 times/week n>for 6 weeks. Result: After 3 months of treatment Group 1: very good—51n>n>.6%, good—48.4%. Group 2: very good—30%, good—50% and moderate—20%. Conclusion: n>The combination of He-Ne laser with topical clindamycin shows more rapid clinical improvement compared to topical clindamycin alone in the treatment of mild and moderate AV.

应用范德保法测量了电阻率在10-3—102欧姆·厘米范围的n型和p型碳化硅单晶和外延层的电学性质。进行了测定条件的选择,范德保法与普通法的对照等试验。发现接触电阻的大小和稳定程度对测量结果有极大的影响。在铟、紫铜、锡、磷铜等机械接触中,铟电极具有最低的接触电阻,其他电极须经电冶成方能进行测定。在不同的电极材料和样品电流下,电阻率偏离约2%,指出,样品电流应当根据具体样品的电阻率和接触电阻加以选择。与普通法比较,范德保法精确度高,数据重复性好。测量了自室温至1000°k范围内碳化硅单晶的高温电学性质,求得氮施主的电离能为0.056电子伏。讨论了引起实验误差的一些异常现象及其产生原因。
