In this thesis. Interband coding techniques are investigated for effective compression of multiband images such as color images and hyperspectral images. A multiband lossless compression system based on context matching prediction schemes is proposed. The observation is that the interband correlation in multiband images is usually greater than the intraband.

中文摘要此论文探讨有效率的压缩彩色影像及卫星影像类型的多频带影像利用频带间预测编码的技术，提出一种基於频带间内文比对预测方式的多频带影像无失真压缩系统，观察结果显示多频带影像邻近频带相互之间冗余特性大於频带内。

In speech communication, almost half of the time is the silence state, which contains much redundant information need to be taken away to improve code efficiency, so the silence frame should be compressed; On the other hand, to satisfy people's listening feelings, speech code implemented on UWB would be a new future's research direction on speech code. Nowadays the compression on narrow band or wideband have been studied a lot, but the silence compression on UWB need to be studied more, which is the main job of this paper.

在语音通信中，平均一半的时间处于无语音的空闲状态，这里蕴含着大量的冗余信息，所以去掉这些冗余信息将会大幅度的提高语音编码的传输效率，这就需要对静音信号进行压缩；此外，为了满足人们听觉享受，在高带上实现语音编码也将成为未来的研究方向，现如今窄带和宽带的静音压缩技术已经较为成熟，但高带的静音压缩技术尚待发展，这也正是本文研究的必要性。

The results of this study indicate that changing the angle of the intake port has a profound effect on the flow field during the intake stroke of the engine cycle. For the case with the intake-exhaust valves canted at zero degree (the so-called vertical valves), the tumble ratio, swirl ratio, turbulent intensity, and turbulent kinetic energy in the direction perpendicular to the bisecting plane of the cylinder are at their highest levels than those obtained for the other cases. This effect is most pronounced after the compression stroke of the cycle. As a result of this study, it is observed that the behavior of the overall flow field from the intake to the completion of compression stroke has a major impact on the effectiveness of the mixing of fuel-air prior to the ignition of the engine cycle.

结果显示，改变进排气阀的倾斜角度对进气期间的流场变化有很明显的影响，其中以垂直阀(进排气阀倾斜0度)所得的 Y轴向(Y方向系垂直於将汽缸对分为二平面的方向)滚流强度、涡漩比、紊流强度、紊流动能等流场强度为最强；若以流体经活塞压缩后的流场特性进行探讨，所得结果显示压缩冲程对汽缸内流场的效应是不容忽视的；因此由进气到压缩过程结束的整体流场现象，才是影响引擎点火前的油气混合程度与燃烧品质的关键。

Critical compression stress is an important index to evaluate the compression properties of paper honeycombs.

纸蜂窝面外压缩临界应力是评估纸蜂窝承压性能的一个重要指标。

The damage and failure modes of brittle materials under tension and compression are different. The self-similar growth of open microcracks under tension, the frictional sliding, mode-n self-similar growth and kinking of closed microcracks under compression and their influences on the mechanical properties of materials are studied in detail.

在拉伸和压缩情况下微裂纹损伤机制和材料破坏模式都不相同，本文对张开微裂纹的自相似扩展和闭合微裂纹的摩擦滑移、自相似扩展、弯折扩展进行了详细的研究，分别给出了它们对材料的宏观力学性质的影响。

In Ogg compression, the TL-60 is clearly outdistanced by Core Duo whereas in compression MP3, the variation is weaker.

在ogg格式压缩，铊- 60显然是落后于二人的核心，而在压缩的mp3 ，变弱。

Acid-washing passivation report being degrease 2, oxygen junction row 3, is degrease asking should check up every component and part burr clean, the greasy dirt uses cleaning agent Ccl4 solution to clean derosination after washing outside , use Shimizu to rush cleanly and , use air compression to puff trunk and then , use cotton waste brush to erase the electuary and the oxide , clean uses air compression to puff trunk together then with Shimizu irrigation on scribbling in workpiece in acid-washing passivation being lubricated outside down homogeneously , after 20 minutes.
