求翻译：左图所示为中国海洋大学海洋生命学院所做深紫外LED杀菌实验对比图。左侧图片为未用深紫外LED处理的培养皿，中间图示为深紫外LED（单颗裸芯）距离培养菌1cm的情况下，20s、40s所达到的效果。由此可见，深紫外LED在短时间内可实现较好的杀菌效果。是什么意思？

Shown on the left is made to the Marine Life Sciences, Ocean University of China DUV led sterilization experiments comparison chart. The left side of the picture for unused the DUV led processing Petri dish, the middle icon for the DUV LED (single naked core) from the cultured bacteria 1cm, 20s, 40s

The diagram on the left shows the Ocean University of China Marine life make the academy deep UV germicidal LED experimental comparison chart. The left picture is not used for deep UV LED the Petri dish, the middle figure shows the deep UV LED (single die) 1 cm distance from cultures of the 20 s, 40

The left chart shows for China Oceanography University Sea Life Institute makes the deep ultraviolet LED sterilization experiment contrast chart.Left side the picture for with the deep ultraviolet LED processing culture dish, the middle graphical representation (Shan Keluo the core) has not been awa

Figure on the left shows the Ocean University ocean life Institute doing deep UV LED sterilization experiments compared. Left picture is not used in deep UV LED Petri, pictured in the middle and deep UV LED (single core-nude) 1cm case distance training bacteria, 20s, 40s, the effect achieved. Thus,
