摘要:
A method according to the present invention has: isolating, by extraction, particles contained in a metal material to be analyzed in a solution using a particle isolator; dispersing the particles isolated by extraction into a solvent to prepare a dispersion, and fractionating the dispersion into a plurality of particle dispersions based on particle sizes, using a field flow fractionator; and irradiating laser light on each of the particle dispersions separated based on predetermined particle sizes, to thereby measure absolute values of the particle size based on angular dependence of reflection intensity, and also to thereby measure the number density based on magnitude of reflection intensity.

摘要:
A cold-gas-blow-cooling type machining apparatus including a relative movement device which moves a workpiece and a machining tool relative to each other, and a cold-gas-blow supply device which supplies a cold gas blow to a machining point at which the workpiece is machined by the machining tool. The machining apparatus includes: a workpiece-temperature detecting device which detects a temperature of the workpiece; and a machining-condition control device which controls at least one of the relative movement device and the cold-gas-blow supply device, on the basis of the detected temperature of the workpiece. The machining-condition control device includes a cooling-condition control device which controls the cold-gas-blow supply device so as to control at least one of a temperature and a flow rate of the cold gas blow.
