熏蒸消毒室

Objective To Study of Air-disinfecting effects of eucalyptus disinfector for asepsis room.

目的观察桉树叶熏蒸法对无菌室空气消毒的效果。

Depending on the results of the environmental monitoring the clean rooms are fumigated to eliminate microbiological contamination in inaccessible places.

根据环境监测的结果对洁净室进行熏蒸消毒以去除难以清洁位置的微生物的污染。

The average kill rate against natural bacteria on kitchenware, such as table top, chopping block, knife, cupboard, porcelain bowl and the surface of refreshing box of the refrigerator were all above 0.972 0 when cleaning and polishing with vinegar solution for 10 min.

结果 不同浓度的食醋溶液作用不同时间对金黄色葡萄球菌、大肠杆菌和白色念珠菌的杀灭效果不同，浓度越大、作用时间越长杀菌效果越好（F=6.89～156.83，P.05）；对手自然菌作用2 min，平均杀灭率为0.991 5±0.003 2；对厨房内台面、砧板、菜刀、碗柜、瓷碗、冰箱保鲜室表面擦拭消毒10 min，对自然菌的平均杀灭率在0.972 0以上；对室内空气自然菌的杀灭率随熏蒸时间的延长而提高（F=121 2.13、502 4.46，P.05），当室内有人时，杀灭率有所降低（t=5.08～30.48，P.05）；置于54 ℃恒温箱（相对湿度≥0.75）存放14 d，醋酸总含量下降

Results Different concentrations of vinegar with different disinfection duration showed significantly different bactericidal effect on Staphylococcus, Escherichia and Candida albicans (F=6.89~156.83, P.05). The effect was better along with higher concentration and longer duration. The average kill rate against natural bacteria on hands was 0.9915±0.0032 after exposed to vinegar solution for 2 min. The average kill rate against natural bacteria on kitchenware, such as table top, chopping block, knife, cupboard, porcelain bowl and the surface of refreshing box of the refrigerator were all above 0.9720 when cleaning and polishing with vinegar solution for 10min. The bactericidal efficacy of vinegar against natural bacteria in room air was enhanced with fumigating duration prolonged (F=1212.13, 5024.46; P.05), while lowered when there were persons in it (t=5.08-30.48, P.05). The content of acetic acid in vinegar dropped by 8.372 g/L when it was stored at 54℃(relative humidity 0.75) for 14 days.

The absorption and distribution of chromium were studied in ryeusing nutrient culture technique and pot experiment.

采用不同浓度K2CrO4(0，0.4，0.8和1.2 mmol/L)的Hoagland营养液处理黑麦幼苗，测定铬在黑麦体内的亚细胞分布、铬化学形态及不同部位的积累。

By analyzing theory foundation of mathematical morphology in the digital image processing, researching morphology arithmetic of the binary Image, discussing two basic forms for the least structure element: dilation and erosion.

通过分析数学形态学在图像中的理论基础，研究二值图像的形态分析算法，探讨最小结构元素的两种基本形态：膨胀和腐蚀；分析了数学形态学复杂算法的基本原理，把数学形态学的部分并行处理理念引入到家实际应用中。
