目的观察复合杀虫剂快速杀灭室内白纹伊蚊Aedes albopictus的药物效果。方法采用实验组施药前后蚊虫密度变化和实验组与对照组蚊虫密度变化评价杀灭药效。结果实验组在施药后30 min白纹伊蚊全部被杀灭,连续观察到第6天没有发现白纹伊蚊,而对照组白纹伊蚊密度基本无变化;到第7~8天实验组开始出现白纹伊蚊,其密度与对照组无明显差别。结论复合杀虫剂对室内白纹伊蚊具有好的快速杀灭效果,药效可持续6d。
Objective To observe the drug effect of compound insecticides on rapidly killing Aedes albopictus indoors. Methods The changes of mosquito density in experimental group before and after spraying and the mosquito density change in experimental group and control group were evaluated to kill the effect. Results In the experimental group, Aedes albopictus was completely destroyed 30 min after application, and no Aedes albopictus was found on the 6th day, while the Aedes albopictus density was almost unchanged in the control group. On the 7th to 8th day, Aedes albopictus began to appear in the group with no significant difference in density compared with the control group. Conclusion The compound insecticides have a good fast killing effect against indoor Aedes albopictus, and the efficacy can be sustained for 6 days.

目的特征降维是机器学习领域的热点研究问题。现有的低秩稀疏保持投影方法忽略了原始数据空间和降维后的低维空间之间的信息损失,且现有的方法不能有效处理少量有标签数据和大量无标签数据的情况,针对这两个问题,提出基于低秩稀疏图嵌入的半监督特征选择方法(LRSE)。方法 LRSE方法包含两步:第1步是充分利用有标签数据和无标签数据分别学习其低秩稀疏表示,第2步是在目标函数中同时考虑数据降维前后的信息差异和降维
