The computed cosine invariants were compared with the observed values, and it was found that invariants for which the true value is relatively large are computed more accurately than invariants having smaller values.作者: 冒煙 時(shí)間: 2025-3-22 14:43 作者: 冒煙 時(shí)間: 2025-3-22 18:50 作者: 新星 時(shí)間: 2025-3-22 23:39 作者: infarct 時(shí)間: 2025-3-23 05:19
