块

After the detailed analysis of those macro-blocks that have no forward motion estimation, the motion information is given approximatively relative to their previous reference frames.

首先根据DCT变换和MPEG编码算法，推导出子块的时空偏导数的近似计算方法，并提出了针对不同类型宏块的处理办法，然后给出了MPEG视频序列的光流场估计算法。

The hydraulic in this design is a general beam-column type one, which is made up by the mainframe, electrical system and hydraulic system. It can be operated by autoloading fashion, manual fashion or spot moving fashion, to achieve the following process: sliding down rapid; sliding down slowly; adding pressure; keeping pressure; removing pressure; the low hydraulic tank work out; the low hydraulic tank untreading.

本设计中的液压机属于梁柱式一般用途液压机，主要由主机、电气系统和液压系统等三部分组成，采用半自动、手动和点动三种操作方式，能实现以下几个工作过程：滑块快速下行；滑块慢速工进；加压成型；保压延时；卸压回程；顶出缸顶出；顶出缸退回。

Identification of these cells: Over 90% cells isolated from human fetal calvaria were stained positively for both alkaline phosphatase and Alizarin red.

采用酶消化后植块的改良植块培养法可在较短时间内获得大量成骨细胞，这些细胞具有典型的成骨细胞形态和功能，是一种较好的分离培养人胚成骨细胞的方法。

Its operating principle is that electric energy is changed into mechanical energy by drive unit, then the liquid in the cylinder body forms high and low pressure to drive piston up by impeller circumrotation, so vertical motion is changed into wagging of brake arm by leverage and declutch is completed. This product has passed the experiment test by National Quality Supervise Administration and every technical criterion is accorded with national trade standard.

电力液压块式制动器包括电力液压推动器和块式制动架两部分组成，其工作原理是通过驱动装置的电能变成机械能，通过叶轮旋转，使缸体内液形成高低压腔推动活塞向上运动，从而通过杠杆机构将垂直运动转变成制动臂的左右摆动、完成松闸。

ROM of the following construct fixation with Codman plates, Window plates with grafts and 1 mm shortened grafts were measured respectively, and the graft height were determined for each specimens by physical measurement of discectomy site.

将12例小牛颈椎标本随机分成两组，用生物力学测定仪测定正常颈椎C(下标 4/5)节段在前屈、后伸、左右侧屈、左右旋转时的三维运动范围，然后切除C(下标 4/5)椎间盘，制成损伤模型，测定植骨加钢板，植骨块缩短1mm加钢板固定后C(下标 4/5)节段的ROM，植骨块的长度根据测量椎间隙的高度而定。

Dapingzi highway tunnel is located in sound potash granite covered by debris.The overburden of the tunnel is relatively thin and the bias is great. In entrance zone,slope surface is covered with thick deluvial,colluvial,alluvial debris,resulting in difficult tunneling condition.

锦屏电站专用公路大坪子隧道岩体为钾长花岗岩，岩体完整性较好，表层为块碎石土，但隧道埋深较浅，偏压严重，进洞口段边坡表面覆盖有较厚的坡崩冲积块碎石土，成型进洞困难。

The log buffer is used cyclically in this way until i maps to the last block in the log file.

这个时候，i指向了日志产生的块5，这个对应着日志文件的块106。

In low basicity, because of the low melting of the slag phase, it is bad for the gas-solid reaction of ferric iron oxide and separating iron from slag The research discovered: Sulfur can be deprived above 90% during direct reduction. The mechanic of desulphurization is gasification desulphur.

研究发现，在直接还原过程中可以脱除90%以上的硫，脱硫主要机理是气化脱硫，内配煤团块中的硫化物和有机硫进入气相，一部分随炉气脱离团块，一部分被配入的CaO吸收。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.
