英语翻译把下面这句话翻译成英语 ;直径大于等于0.05mm的粒子数不能超过1000个,大于等于0.5mm的粒子数不能超过

Among all the particles,the number of the ones whose diameter is longer than 0.05mm should be less than 1000,and the number of the ones whose diameter is equal to 0.5mm shuold be less than 7,otherwise the fan speed needs to be adjusted..

Diameter greater than or equal to 0.05 mm of particle count cannot exceed 1000, greater than or equal to 0.5 mm of particle count cannot exceed seven, or need to adjust fan wind speeds.

The quantity of particles with diameter bigger than or equal to 0.05mm cannot exceed 1000pcs,particles bigger than or equal to 0.5mm cannot exceed 7pcs,otherwise the wind speed of fan should be adjusted.

0.05mm diameter greater than equal to the number of particles can not exceed 1000, the number of particles greater than 0.5mm is not equal to more than 7, or need to adjust the fan speed.
