This scheme was composed of two parts: intra prediction and inter prediction. For the intra prediction part, 8×8 block DCT-HT transform-domain converse was used, and then intra mode decision was done in HT domain to obtain the optimum mode, so that good intra prediction was acquired. For the inter prediction part, Motion Vector got from Variable Length Decoding in MPEG-2 stream was reused as Prediction Motion Vector of H.264, then motion prediction mode and search region were reset, so that better prediction result was acquired.
该方案中,帧内预测使用了8×8块的DCT-HT的变换域转换,然后在HT域进行Intra模式判决得出最优模式,从而得到理想的帧内预测;帧间预测重用了MPEG-2码流中变字长解码得到的运动矢量MV,作为H.264的PMV,通过重新设定运动预测模式以及搜索范围,从而获得较好的预测效果。

And this strain degraded H〓S without lag time. The heterotrophic bacteria's generation period was short and its growth was rapid. The result of experiment indicated when the strain Hm-6 was applying to the packed tower, the startup was more quickly and the control was more convenient than the autotrophic bacterium. Applying to deodorize the H〓S, the better removalability could be got. At the same time, comparing with the system used at home of which the biofilm directly formed with activated sludge, it runs in the neutral condition, has lower corrusivity to the equipment and was liable to handle. And this system didn't need the acclimation to become biofilm, so it can save a rather long acclimation time.

Beijing Institute of Technology, Beijing 100081,ChinaIn order to get the high output power, a RF excited diffusively cooled all-metal slab waveguide CO2 laser was reported, in which gas discharge region was constructed by two aluminum side walls and aluminum electrodes. The region dimension was 2 mm height×20 mm width×386 mm length, and the gas composition was CO2:N2:He:Xe=1:1:3:0.26. This technique replaced the old ceramic and metal sandwich waveguide technique.The optimum out power 127 W was achieved from the RF excited diffusively cooled all-metal slab waveguide CO2 laser with the longitudinal voltage uniformity distribution technique and scaling area technique. The electro-optic conversion efficiency was about 14%.

During the calculation the results got by quintic spline kernel was the best so it was chosen as the proper kernel for the SPH simulation. By comparison of the simulation results got by SPH and finite volume method, it was proved that the buffer cells method proposed in the SPH simulation to implement the Dirichlet boundary conditions was accurate, and this is of great importance for the simulation of flows pass a pipe. At last, the SPH method was improved to simulate the liquid-solid two phase flows and the results show that this method was appropriate for the simulation of flows containing viscous fluid and macroscopic solid components. Now the two methods are both able to predict the continuum flows and rarefied flows severally, but the hybrid program still has some aspects to be improved.

It does the more enrapture me,And even so, I still remainA lover in captivity.Greensleeves was all my joy,Greensleeves was my delight,Greensleeves was my heart of gold,And who but my lady greensleeves.3 Greensleeves, now farewell, adieu,God I pray will prosper thee,For I am still thy lover true,Come once again and love me.Greensleeves was all my joy,Greensleeves was my delight,Greensleeves was my heart of gold,And who but my lady greensleeves.
Adrain个人小观点:这首诗简约而又生动忧伤,值得大家注意的是它所描写的故事是一个君王对一个平民女子的爱,在诗里,这位君主的爱超越了阶层,也超越了物质和生死,假设和对比手法的运用将感情抒发到了极致,爱的忧伤不仅仅是忧伤,在诗里也是一种美。

CHAPTER XI OFFERS OF SERVICE FROM MISERY TO WRETCHEDNESS Chinese Marius ascended the stairs of the hovel with slow steps; at the moment when he was about to re-enter his cell, he caught sight of the elder Jondrette girl following him through the corridor. The very sight of this girl was odious to him; it was she who had his five francs, it was too late to demand them back, the cab was no longer there,the fiacre was far away.
