本文导出了六方晶体的热膨胀理论，并对石墨的实验数据作了定量的解释。对石墨的某些弹性模量进行了估算，其值为18°C。约：s11+s12= 1.8×10-13 cm。/达因s13=-4.3 10 -13 cm./达因s33= 58.5×10-13 cm./因此，在18°C时，近似：k垂直=-2.5 10 -13 cm 2/dyne; k平行=50×10-13 cm 2/。达因。
A theory of the thermal expansion of hexagonal crystals is derived, and shown to account quantitatively for the experimental data on graphite. Certain of the elastic moduli for graphite are estimated, and are at 18°c. approximately: s11+s12= 1.8×10-13 cm./dyne s13=-4.3×10-13 cm./dyne s33= 58.5×10-13 cm./dyne Hence the two linear compressibilities are, at 18°c., approximately: kperpendicular=-2.5×10-13 cm2/dyne; kparallel=50×10-13 cm2./dyne.
