Image compression based on the second generation Bandelets transform,whose optimized bandeletization is controlled by quantization step,cannot realize fixed bitrate image compression.

由于第二代Bandelets变换是由量化步长来控制最佳Bandelet化过程，难以实现定码率图像压缩。

In this paper, the instantaneous deformation and failure characteristics, creep characteristics of gypsum breccias under different confining pressures and stress levels are studied by means of conventional triaxial compression tests and uniaxial and triaxial compression creep test s.

As with any other Stirling device, heat flows from the expansion space to the compression space; however, in contrast to the Stirling engine, the expansion space is at a lower temperature than the compression space, so instead of producing work, an input of mechanical work is required by the system (in order to satisfy the second law of thermodynamics).

与任何其他斯特林装置，热流量的扩大空间的压缩空间；然而，在对比的是斯特林发动机，扩大空间，在更低的温度比压缩空间，所以不是生产工作，投入机械工作所需要的制度（为了满足热力学第二定律）。

Vibrating objects create sound waves. When you speak into one of the cups, your vocal chords vibrate to create sound waves. Sound waves are compression waves , which means they move by the compression of a fluid.

震动的物体会产生声波，当你对著杯子说话时，你的声带震动产生了声波，声波是一种压力波，这表示它们随著流体的压力而传播。

Neurology also influences the surgical approach when there is cord compression from a vertebral body fracture, anterior traumatic disc protrusion, or a facet fragment causing foraminal root compression.

当脊髓压迫来自骨折的椎体，前方破裂突出的椎间盘，或关节突的骨折片引起椎间孔的神经根受压时，神经状态同样能影响手术入路。

The simulation results shows that when the hydroforming for real axle housing needs two bulge processes and the specific value of the two bulge ratio is about 1, the result is the best one; To obtain an appropriate route of loading force need adjust internal pressure and axial compression force for many times and according to the failure, the size of the two forces which has been mentioned can be rapidly and rationally adjusted; Because of good greasing conditions influencing largely, reducing the friction between tube blank and die inside surface as well as possibly not only makes more materials flow into the bulge area but effectively diminishes the axial compression force; The good or bad characteristics of tube blank material is also one of the decisive factors and when material is selected, we first consider its' formability.

模拟结果表明，当后桥壳需要两次进行胀形，两次胀形比比值约等于1时，胀形结果最好；合适的加载路径要经过多次调试，能根据胀形缺陷对内压力和轴向力的大小进行迅速地合理调整；良好的润滑环境对后桥壳液压胀形的影响巨大，要尽量减小管坯与模腔内壁的摩擦力，不但使更多的材料流入胀形区，而且能有效的降低轴向力的大小；管坯材料性能的好坏也是影响胀形的决定性因素，选材时首先要考虑材料的成形性。

"Second Life is remarkably easy to work with, and is very popular,"

"第二次生命是显着容易的工作，并且很受欢迎，"

For example, we usually assume that materials are homogeneous and isotropic and free of internal defects or flaws.
