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.

随着现代无线通信特别是多媒体通信的发展，人们对语音通信的质量要求越来越高。3GPP/ETSI TS026和ITU-T 722.2标准确定的自适应宽带语音编解码器AMR-WB具有的低比特率、互操作性和高语音质量，使之不仅能够应用于无线通信领域，而且可广泛应用于其他各种通信系统和平台，包括：VoIP、因特网、PSTN高质量音频会议、音频流、ISDN宽带电话、ISDN可视电话和电视会议等。

There is an allotropic change temperature (1155K) for pure Ti and it is a hydrogen-absorbing metal for different solubility in a-phase titanium and 3-phase titanium. The hydrogen atom dissolves in lattice and occupies tetrahedron interstitial position, and then forms TiH2 sublattice of face-centered cubic.

钛是－种具有同素异型转变点T(1155K)的吸氢金属，氢在α钛和β钛中有不同的溶解度，在T以下易形成具有面心立方晶格结构的TiH2，氢原子溶解在晶格中，占据四面体间隙位。

AITL, diagnosed based on lymph-node biopsy, was characterized by damage to normal structure of lymphonodus, proliferation of immunoblastic cells, and arborescent supervascularization.

The 3-year survival rate was 25%, with a median survival time of 20 months.
