英文摘要：

The nonlinearity rectification is an important task to improving the sensor performance. This paper analyzes the sensors characteristics and designs a fitness function with interest in normal distribution and use boundary functions presents a new method named SGEP. The new method based on Gene Expression Programruing is for solving the problem of the nonlinearity rectification in sensor system. The experimental result show that the new method is more effective and more flexible than traditional method. Key words：
