本测试仪主要用于高精度测量恒弹性合金的频率温度系数和机械品质因素,也可用作研究材料声频内耗的工具。 仪器由信号测试系统、-40～+80℃真空测试炉和试样夹持机架三部分组成。主要性能指标: 1.测频率温发系数1×10~(-7)/℃时,误差<10％; 2、测机械品质因素不小于5.00×10~4 The tester is mainly used for high-precision measurement of constant temperature alloy frequency and temperature coefficient of quality factors, but also can be used as a tool to study the material’s internal friction. Instrument from the signal test system, -40 ~ +80 ℃ vacuum test furnace and sample holder rack composed of three parts. The main performance indicators: 1. Measuring frequency rate of hair temperature 1 × 10 ~ (-7) / ℃, the error <10%; 2, measuring mechanical quality factor of not less than 5.00 × 10 ~ 4
