And now I want to add on, so I'm gonna hook the next vector on to the front of the arrow, we'll start next vector, and I will go this way, so let's see, can I do it right?

现在我要加上…我要将下一个向量钩住这个箭头的前端，我们将会开始下一个向量，我将这样做，让我们来看，我做的对么？

Wavelet packet decompresses vibration signals, and wavelet packet nodes which are sensitive to the change of state, as eigen-nodes, form a decomposition tree; the signal restructured at all eigen-nodes can be used as the fingerprint in many breaker diagnostic systems. Support vector machine with the "most important" factors at eigen-nodes as input vector classifies the states at "one to others" strategy.

首先利用小波包分解振动数据，提取状态变化敏感节点作为特征节点形成分解树，利用敏感节点重构完好状态振动信号，并以此作为当前大多断路器诊断系统中使用的指纹信号；同时提取特征节点最大系数形成特征向量，作为支持向量机的输入向量，使用&一对其余&策略进行特征分类。

METHODS Human IL 6 gene was reconstructed in retrovirus vector and transferred into incasing cells PA317 by lipofectamine mediated method. The clones of the cells transferred with hIL 6 were selected by G418. Targeted NIH3T3 cells were infected with the virus granules secreted from PA317 and also selected by G418. The insertion and expression of hIL 6 gene in NIH3T3 cells were analysed with Southern blot and Northern blot. RESULTS Human IL 6 retrovirus vector (pZIPIL-6) was successfully reconstructed.

利用重组载体构建技术将质粒pUCIL 6 cDNA的目的片段连接于逆转录病毒载体上，并以脂质体介导的方法将重组载体转染包装细胞PA317，以G418筛选克隆细胞，浓缩克隆细胞上清以制备重组病毒液，继之感染NIH3T3细胞后，进行Southern blot和Northern blot分析，检测目的基因在靶细胞的整合与转录水平。

The temporal segmentation localizes moving objects by comparing the motion vector of each block in each frame with the corresponding global motion vector.

为了减小分割算法的计算量，第六章根据第五章所分析的空时融合分割算法的技术难点，提出了一种基于时空补偿的空时融合分割算法。

Coli JM109 (DE3) transformant containing the 〓-tagging vector with the gene leuS was approximately 110 times that of JM109 (DE3)(the host strain without the vector). The overproduced 〓-fusion leucyl-tRNA synthetase can be purified to homogeneity under native condition within two hours by one step affinity chromatography with an overall yield of 55%.

高表达的N—端带有6个连续组氨酸的LeuRS经过一步Ni-NTASuperflow亲和层析可以达到90％以上的纯度，产率为55％，纯化时间仅为2小时，而且LeuRS所带的〓-标签对酶的结构和功能都没有影响。
