The flexible ferrite production was $215M in 1999 increasing to $368M in 2001. Its global production in 1999 was 100,000 Tons increasing to ~ 115,000 Tons in 2001 [.,.,.].作者: 創(chuàng)作 時(shí)間: 2025-3-22 02:17 作者: subordinate 時(shí)間: 2025-3-22 08:15 作者: avenge 時(shí)間: 2025-3-22 10:15 作者: STING 時(shí)間: 2025-3-22 16:56
