从测得的声速到液氦温度，测定了单晶方铅矿的弹性常数。描述了一种包括在低温下注射液体粘合材料的装置的低温恒温器。在5K时，弹性常数C11=14.90，C12=3.51，C44=2.92×1010N/m2。
The elastic constants of single crystal galena have been determined from the measured ultrasonic velocities down to liquid helium temperature. A cryostat incorporating an arrangement to inject the liquid bonding material at low temperature is described. At 5 K, the values of elastic constants are C11=14.90, C12=3.51 and C44=2.92×1010 N/m2.
