中文摘要：

针对离散的基因芯片表达数据难以进行系统分析的问题，提出基因芯片数据的y-n曲线模型，将基因芯片数据转化为唯一的一列信号，从而可以对其进行多尺度分析。对人类胎儿脑发育过程中大脑皮质基因表达基于y-n曲线模型进行小波多尺度降噪，结果证明，y-n曲线的降噪效果比用基因芯片原始数据更好。

英文摘要：

The model of y-n curve is set up to solve the problem that discrete gene chip data are difficult to be systematically analyzed, which makes the data be changed into a row of sole signal, and can be studied by multi-scale analysis. Results of denoising the cerebral cortex gene expression of developing human brain based on wavelet multi-scale analysis show that the denoised effect of y-n curve is better than that of raw data.
