摘 要
高温环境对传感器性能稳定性与可靠性提出了严峻挑战，广泛存在于航空航天、工业制造等领域。本研究旨在深入探讨高温环境下不同类型传感器的性能变化规律及其影响因素，以期为高温环境下传感器的选择和应用提供理论依据和技术支持。通过对比分析热电偶、热电阻等常见高温传感器在不同温度梯度下的输出特性，采用实验测试与数值模拟相结合的方法，构建了高温环境下的传感器性能评估模型。研究发现，随着温度升高，传感器的灵敏度逐渐降低，响应时间延长，非线性误差增大。创新性地引入了基于机器学习算法的补偿机制，有效提高了传感器在极端温度条件下的测量精度和长期稳定性。通过对大量实验数据的统计分析，验证了该补偿机制的可行性和有效性，使传感器在800℃以上的高温环境中仍能保持良好的工作状态。

Abstract
High temperature environment poses severe challenges to the performance stability and reliability of sensors, which widely exists in aerospace, industrial manufacturing and other fields. The purpose of this study is to deeply explore the performance changes and influencing factors of different types of sensors in high temperature environment, in order to provide theoretical basis and technical support for the selection and application of sensors in high temperature environment. By comparing the output characteristics of common high temperature sensors such as thermocouple and thermoelectric resistance, and using the method of combining experimental test and numerical simulation, the performance evaluation model of sensors in high temperature environment is constructed. It is found that as the sensor sensitivity gradually decreases, the response time is increased, and the nonlinear error increases. The compensation mechanism based on the machine learning algorithm is innovatively introduced, which effectively improves the measurement accuracy and long-term stability of the sensor under extreme temperature conditions. Statistical analysis of extensive experimental data verifies the feasibility and effectiveness of the compensation mechanism, so that the sensor can still maintain a good working condition in a high temperature environment above 800℃.
