Dr Marka calculates that if there is a 6% chance that a mosquito will penetrate a light curtain, and a hut contains four curtains, then only one in 100,000 mosquitoes will be able to spread malaria.

马尔卡博士估算假如一只蚊子有6%的机会穿过光帘幕，并且一个草屋设有四道帘幕，那么在一百万只蚊子中仅有一只有机会能够传播疟疾。

The idea is that when a mosquito encounters the infra-red curtain, its senses are overwhelmed and it flies away.

这个设计的理念是当蚊子碰到红外线帘子的时候，它的感官被扰乱，随后就飞走了。
