文摘

Solar non-uniform temperature field test of a telescope’s reflector is conducted initially. Time-varying distribution regularities are analyzed contrastively. Simulation methods are proposed involving environmental factors and self-shadowing. Refined discrimination method for the shadow distribution is put forward. Validity of simulation methods is evaluated with the experimental data.
