I46S是国内正在研制的用于彩色显象管阴罩温度补偿片的专用热双金属材料。本文针对装管材料性能测量精度的要求,较全面地论述了用悬臂梁法测量比弯曲K时的仪器精度和测量条件与该种材料K的关系。通过对测量仪器的误差分析,得出厚度,温度,挠度测量精度对K系统误差影响较大,厚度与温度尤为明显。当其中组成仪器精度测厚0.01mm,测长
I46S is being developed for the domestic color cathode ray tube shadow mask temperature compensation dedicated thermal double metal material. In this paper, according to the requirements of pipe material performance measurement accuracy, a more comprehensive discussion of the relationship between the instrument accuracy and measuring conditions and the K of the material when using the cantilever method to measure the bending K is more fully discussed. Through the error analysis of measuring instruments, it is concluded that the measurement accuracy of thickness, temperature and deflection have a great influence on the error of K system, especially the thickness and temperature. When the instrument precision measurement thickness 0.01mm, length measurement
