本文详细描述了我们为研究聚合物(约5cps)的低温动态力学性能而研制的自由振动簧片装置。该仪器能够测量从4到340K的这些性质。与其他方法相比，该方法具有相对容易设置的优点，并且可以进行修改，以便在给定的温度运行中可以研究不止一个样品。此外，还测量了聚苯乙烯的对数衰减率和杨氏模数，并与前人的数据进行了比较。
This paper describes in detail a freely vibrating reed apparatus which we have developed to study these low temperature dynamic mechanical properties of polymers (at approximately 5 cps). The apparatus is capable of measuring these properties from 4 up to 340 K. This method has the advantage over other methods of being relatively easy to set up and may be modified so more than one specimen can be investigated in a given temperature run. In addition measurements on the logarithmic decrement and Young's modulus of polystyrene are presented and compared with previous data.
