The last known case was in Britain in 1978 when a university photographer who worked above a lab handling smallpox died after being accidentally exposed to it from the building's air duct system.
众所周知的世上最后一例天花发生在1978年的英国。 那是一个(无辜的)大学摄影师,当时他正在天花实验室的楼上房间里工作,死于接触到大楼的风道系统偶然带出来的天花病毒。 (译者注:这位摄影师也太冤了。)
The SPRD is used on zone systems when the automatic closing of various zone dampers can create an excessive increase in air pressure and velocity throughout the duct system.
SPRD旁通阀是当各种区域风门自动关闭时用在区域系统中,可以在管道系统中增加空气压力盒速度。
The SPRD will automatically open as the air pressure in the duct system increases, in order to prevent the reduction of air flow and excessive noise and velocity through the duct system.
当管道系统空气压力增加时,SPRD会自动开启,以防止管道系统中空气流动的减少和过度噪音和速度。
