According to making the controller of Swiss expert group of afore-mentioned nuclear power microscope Wuersi Sitaofu says, this microscope is the smallest the details that can control 100 accept rice emerges come out, than " phoenix " the enlarge multiple of the uses all the time before this optical microscope on date is 100 times higher.

Have the aid of first photograph that this nuclear power microscope films, it is heretofore external the picture with the enlarge the biggest multiple that astral object films, can let Martian soil " fine fine long hair finishs now " .
