Samuel Sheng,Robert Brodersen. Coupled with globalization and the forces of market economy, China’s modernization drive appears to favor only two dominant languages, Chinese as the national commonly-used language and English as the world language (cf. Ross, 1993; Spolsky & Shohamy, 1999, pp. 156–186).作者: VICT 時(shí)間: 2025-3-23 23:16 作者: 煩擾 時(shí)間: 2025-3-24 03:49 作者: colloquial 時(shí)間: 2025-3-24 09:37

Samuel Sheng,Robert Brodersenewed in the context of changing perceptions of tradition, modernization, state-building, and nation-building. We can conclude that China’s tradition, modernization, and state-building all tend to empower one single standard language politically, legally, socioeconomically, and even aesthetically.

Specifically, the 4 parallel outputs of the modulator integrated circuit must be multiplexed back into a 256 MHz serial stream, passed through a state-of-the-art 10 bit ECL D/A converter, and then modulated to a carrier frequency by a 1024 MHz carrier.
