测量了五颗大和陨石（Yamato-7301、-7308、-74191、-74371 和 -74647）的热扩散率和比热。热扩散率测量是在真空（10mmHg或以下）下，在150至550 K的温度范围内进行的。在300-500 K的温度范围内，热扩散率的温度变化非常小。Yamato-7308（如何阿尔陨石）表现出比其他样品（普通球粒陨石）更低的扩散率。样品的比热是在 270 至 420 K 温度范围内的一种大气中测量的。发现所有样品的比热的温度变化几乎相同。
The thermal diffusivity and specific heat of five Yamato meteorites (Yamato-7301, -7308, -74191, -74371 and -74647) were measured. Thermal diffusivity measurement was conducted under vacuum (10mmHg or below) over the temperature range 150 to 550 K. The temperature variation of thermal diffusivity is very small at the temperatures 300-500 K. Yamato-7308 (how ardite) exhibits a lower diffusivity than other samples (ordinary chondrites). The specific heat of the samples was measured in one atmosphere air over the temperature range 270 to 420 K. The temperature variation of the specific heat is found to be almost identical for all samples.
