查询词典 robustness

The test conclusions indicates that the long-term equilibrium relationship between SZZS series and its optimal series is not significant, but the short-term dynamic relationship is comparatively significant; since 2007, the ratio of variance to its mean is more than 0.4, which implies that SZZS is deviated from its optimal level to a great extent, which is the basic feature of bull market or bear market, and this also verify the robustness of these conclusions.

实证结论表明，上证指数序列与其均值序列的长期均衡关系不显著，但短期的动态关系比较明显；从2007年开始，上海股市的标准差/均值相当大，超过了0.4，这意味着上证指数偏离其均值的程度较大，这是牛、熊市的基本特征，这也印证了本文结论的强健性。

The current second-generation and third-generation (3G) mobile communication systems operate with narrow audio bandwidth limited to 200-3400Hz.As wireless systems are evolving from voice-telephony dominated services to multimedia and high-speed data services, the introduction of a wider bandwidth of 50–7000 Hz speech codec which provides substantially improved speech quality and naturalness is quite necessary. The Adaptive Multi-rate Wideband speech codec which was selected by 3GPP/ETSI and ITU-T can provide natural, present and comfortable codec speech and have higher intelligence and robustness in wireless systems. A wide range of applications are envisioned for AMR-WB, including ISDN wideband telephony and audio/video teleconferencing,Voice over IP and Internet applications such as IP video conferencing, voice mail, voice chat, broadcast, and voice streaming.
