摘要:: 在医学仪器测量中，大多数传感器的输入输出呈非线性。针对此问题，本研究在进化规划的基础上引入生物免疫机制，从而形成免疫规划，利用免疫规划来对传感器进行非线性校正。这种方法就是利用免疫规划计算得到校正环节的待定常数，使得整个系统的输出与传感器的输入间呈线性关系。实例分析的结果表明，利用免疫规划对传感器进行传感器的非线性校正，具有较高的校正精度，较快的收敛速度和非常好的稳定性。

Abstract:: In medical instrumentation measurement , most of the input and output of the sensor is nonlinear. To solve this problem,we introduced biological immune system on the basis of the evolution planning, thereby forming immune programming to use non-linear calibration of the sensor. This method could obtain the polynomial coefficients of the nonlinear correction link using the immune programming ,so that the output of the entire system and the input of the sensor were linear . The results of example analysis show that the non-linear calibration to sensor using immunization programs has high correction accuracy, faster convergence speed and very good stability.
