【摘要】 在采用双色法测量柴油机燃烧温度的研究中，发现测试结果因测试波长而异。本文首次详细分析了测试波长对温度测试精度和测试范围的影响，解释了测试结果因波长而异的原因，提出并验证了图象双色法测试波长选择准则。更多还原

【Abstract】 t is discovered that results of temperature measurement are different as measurement wavelength variation when using two color method to measure combustion temperature. This paper first analyzed the influence of measurement wavelength on the precisionand the range of temperature measurement and explained the reason about measurement temperature variating with measurement wavelength, and also proposed and vertified the criterion of measurement wavelength selecting.更多还原
