大家看看这两句怎么翻译啊? 6.5.8.2 thermocouple and resistance thermometer circuits operating high temperature alarms shall have upscale element burn-out. those on low temperature alarms shall fail to downscale position. 关键是upscale和downscale的意思. upscale是高一级的 downscale是低一级的. 句子翻译为: 热电偶和热电阻电路应在熔断高一级元件时执行高温警报.熔断低一级元件时作低温警报. (是否在控制电路中,存在几个控制元件,对应的控制各自的点,编号递升,其控制温度也由低向高,也就是upscale控制高温,downscale控制低温) 6.5.8.3 the range of any temperature measuring instrument shall be the manufacturer's narrowest standard span appropriate to the application 任何测量温度仪表的测量范围应该是制造商适用的最严格的标准范围.查看更多
