低能γ射线反散射法测量煤灰分的线性处理

Linearization Treatment of Measuring the Ash Content of the Coal by Low Energy r-ray Backscattering Techniques

理论计算表明,煤的灰分与低能γ射线反散射强度之间是一种非线性关系。数学分析和实验证明,在较窄的灰分范围内,灰分与反散射强度之间可按线性关系处理。本文结合实际的宽范围的标定曲线,讨论了非线性函数的线性化范围及线性化误差,并对不同的测量范围提供了电路设计的参考数据。

It has been shown by theoretical deduction that the ash content of the coal and low energy r-ray backscattering intensity have a non-linear relation Mathematical analyses and practical tests have proved that relation between the ash content and backscattering intensity may be treated by linear relation.Combining practical wide range calibration curve, the article discusses linearization ranges of non-linear function and linearization error.For different measurement ranges, it provides reference data for circuit design.
