求各位大神给翻译一份摘要 在核电站反应堆棒位测量系统中，控制棒位置测量为核电站运行安全提供依据，因而棒位测量精度显得至关重要。本文从数据处理方面入手，根据在不同温度下，棒位和次级线圈感应电压的关系，应用最小二乘法对试验数据进行拟合。通过三种不同分段方式结果对比，优选出了合适的三段折线拟合区间，建立了三段线性回归模型，并保证了整体区间拟合的连续性。结果表明，此种建模方法整体的测量精度能够达到（-5，+4）步，能很好的达到棒位测量精度要求。 |

| In the Rod position measure system of reactor on nuclear power plant, the measurement of control rod position measurement provides the basis for the operation safety of the nuclear power station, therefore the accuracy of bar position measurement is very important. This paper start with the data processing , the bar and the secondary coil voltage induced by the application of least squares method to fit the test data according to the different temperatures. Through the comparison of the results of three different segmentation methods, a suitable fitting interval of three sections of polyline is optimized and a three-stage linear regression model is established, and the continuity of the whole section fitting is guaranteed. The results show that the overall measurement accuracy of this modeling method can reach (-5, +4) steps, which can meet the requirements of accuracy very well. |
