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.

Prediction approach of potentiality for environmental factors pH,temperature and dissolution oxygen on yeast fermentation was proponed,Based on constructing the membership functions of environmental factors on fermentation process,the fuzzy relation equation model was formed from fuzzy evaluation vector,membership grade matrix and factor weight vector.

提出一种预测环境因子pH、温度和溶氧对酵母发酵影响潜力的方法。在构造环境因子对发酵过程评价的隶属函数的基础上，建立由模糊评价向量、隶属度矩阵和因子权重向量构成的模糊关系方程模型。

DsRNA technology was discovered recently, and many studies demonstrated that it could suppress genes more effectively than antisense technology. Inverted repeats of 800 bp TCS cDNA fragments sandwiching a 400 bp GUS gene fragment was inserted into the binary vector pBI121 and placed under the control of 35S promoter, forming a dsRNA expression vector.

DsRNA技术是近几年才刚刚发展起来的新技术，将上述DNA片段正向和反向插入到双元载体pBI121的35S启动子下游，两片段之间由约400 bp的GUS基因片段隔开，形成反向重复序列，由此构建成了表达TCS基因dsRNA的中间表达载体。
