薄膜热电偶动态响应特性的实验研究钱兰陈宁（西安公路交通大学）引言在内燃机缸内瞬态传热研究中，表面温度法的关键技术之一是壁表面瞬态温度测试的实现。换言之，薄膜热电偶必须能反映出内燃机缸内壁面在内燃机高速运转时的周期温度波动，或者更为有代表性的反映出缸... Experimental Study on Dynamic Response Characteristics of Thin Film Thermocouple QIAN Lan-yan, CHEN Ning (Xi’an Jiaotong University) Introduction In the study of transient heat transfer in internal combustion engine, one of the key technologies of surface temperature method is the realization of transient temperature test on wall surface. In other words, the thin-film thermocouple must reflect the fluctuation of the internal temperature of the internal cylinder of the internal combustion engine during the high-speed operation of the internal combustion engine or, more typically,
