A turbineincludes: a turbine rotor having a rotor main body including a hollow part into which a cooling fluid flows, and a plurality of rotor wheels arranged in an axial direction of the rotor main body and protruding from the rotor main body. A cooling-fluid introducing passage extending from the hollow part in a direction intersecting with the axial direction of the rotor main body is formed in the rotor main body so as to allow the cooling fluid in the hollow part to flow through the cooling-fluid introducing passage and then to flow around the rotor wheel to be conducted to the working-fluid flow passage. A flow-rate control plug regulating a flow rate of the cooling fluid flowing through the cooling-fluid introducing passage is disposed in the cooling-fluid introducing passage.

Image blurring of a mass spectrum image obtained by the signal intensity for each mass/charge ratio from the obtained two-dimensional mass spectrum is reduced by image restoration using a blurring function. The blurring function expresses a two dimensional distribution of transferred energy related to the distance from a point of primary ion incidence limited by a region exceeding desorption energy of a molecule.
