《理化检验一物理分册》编辑部:我是搞金属量器的.金属量器和油尺在不同环境温度下会产生容积和长度变化,对于现行规程中规定的修正方法,其中有两个问题,因查找不到有关资料,限于条件又无法作试验,故请予以指点:1 金属在环境温度变化后,其本身温度变到环境温度,需多少时间?有否公式计算?或如何估计?2 金属在温度变化过程中,其变形是否同步?在温度变化均匀后,即等于环境温度后,变形是否停止?还是要延续一段时间后才能达到该温度下应达到的变形?重要的是这两个变化是否有时间滞后,以及这个滞后各为多少?
Physical and chemical testing of a physical volume of the editorial department: I am engaged in metal gauges. Metal gauges and dipstick in different ambient temperatures will have a volume and length changes, the existing regulations for the correction method, which has two problems , Because can not find the relevant information, limited to the conditions and can not be tested, so please give pointers: 1 metal in the ambient temperature changes, its own temperature to ambient temperature, how much time? Whether the formula is calculated? Or how to estimate? 2 Is metal in the process of temperature change, its deformation is synchronized? After the temperature changes, that is equal to the ambient temperature, the deformation is to stop? Or to continue after a period of time to reach the temperature deformation? It is important that these two Is there any time lag in change and how much is this lag?
