Experiments show that rhomb partitioning is more powerful in suppressing block artifacts than square partitioning, results in much higher reconstructed image quality, but takes longer encoding time; 2 For solving exhausting encoding problem of fractal image coding, we present a fast rhomb-partitioning fractal image coding based on neighbor-searching; we present a fast rhomb-partitioning fractal image coding based on block classification; we present a fast square-partitioning fractal image coding based on neighbor-searching, block classification and wavelet transform.

2针对分形图象压缩编码过程非常耗时的致命弱点，提出了基于邻域搜索的菱形块分割的快速分形图象压缩编码方法，提出了基于块分类的菱形块分割的快速分形图象压缩编码方法，提出了基于邻域搜索·块分类和小波变换的方块分割的快速分形图象压缩编码方法，实验结果表明，我们提出的快速分形图象压缩编码与传统的分形图象压缩编码相比，编码速度提高了近40倍。

By utilizing the unitary matrix, the transmitter decouples the input signal into spatial orthogonal beam directions with the matched filters in beam directions in the receiver, and the gain obtained by each data block can be equivalent to the sum of the projection from the channel matrix to the corresponding beam directions. Beam selection is adopted to maximize the minimum gains of all the blocks, which can improve the system diversity gain efficiently.

发射端采用酉矩阵将数据映射到空间正交的波束方向上，通过接收端波束方向上的匹配滤波，各数据分块所获得的增益为信道矩阵在其波束方向上的投影之和，波束选择通过最大化所有数据分块最小增益，从而有效地提高了系统的分集增益。

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。

Result: All the patients were treated percutaneous reduction and obtained good resuld except one patient who needs another small incision to help reduction and bone graft. The preoperative X ray film showed that the B hler angle was 12.6°, Gissane angle was 75°. The postoperative X ray film demonstrated that B hler angle was 38.5°, Gissane angle was 114.5°.

结果： 14侧手术顺利，达到或接近解剖复位，1侧由于中间骨折块未能达到复位要求，辅助小切口复位骨折块。14侧B hler角由术前12.6°增加到38.5°，Gissane角由术前的75°增加到术后的114.5°，手术前、后差异有统计学意义（P.01）。

Two well-known emission bands related to the isolated Te 1 and Te 2 pair isoelectronic centers were observed for the samples with Te concentrations of 0.5% and 0.65%.

对于Te组分较小的2块样品观察到2个发光峰，分别来自Te1和Te2等电子陷阱；而对Te组分较大的2块样品则只观察到1个来自Te2等电子陷阱的发光。

例如，莫斯科的红场是以500万块比麻将牌还小的红砖铺就而成。而埃及的金字塔则以20万块大理石砌成。美国的科罗拉多河和大峡谷的微缩景观高达32米，一条&巨型瀑布&从16米的高处飞流直冲谷底。

In chapter 1, based on the technology of block matrices and the properties of block diagonal dominances, new results are obtained for the lower bounds of the smallest singular value.

第一章主要通过矩阵的分块和块对角占优性来讨论了最小奇异值的下界。
