The spectral resolution of a Fourier transform spectrometer (FTS) is traditionally expressed as ${\bm \Delta \nu} = {\bf 0.5}/{\bm \delta} _{{\bf max}}$ in which ν is the wavenumber and ${\bm \delta} _{{\bf max}}$ is the maximum optical pathlength difference (OPD). This equation is valid for the moving mirror-based FTS whose OPD is independent of wavelength but inapplicable to the FTS with wavelength-dependent...
Based on the similarity between the regularity for change of technical condition of vehicle and biological population, the paper proposes a simulation model for the overall technical state of system vehicle. First a state transition equation of vehicle service life and a transition equation of vehicle accumulated mileage to measure the number of retired vehicles in a system are established. Then based...
