结果表明，液体在其三相点附近的等温压缩率ξ与表面张力Σ的乘积可以预期为液体的基本长度特性。从30种液体（包括液态金属）的实验数据可以观察到，当ξ和Σ分别以150的倍数变化时，乘积ξΣ变化的倍数小于3，并且总是等于十分之一埃单位。
It is shown that the product of the isothermal compressibility ξ and surface tension Σ of a liquid near its triple point may be expected to be a fundamental length characteristic of the liquid. From experimental data on 30 liquids (including liquid metals) it is observed that while ξ and Σ separately vary by a factor of 150, the product ξΣ varies by a factor of less than 3 and is equal always to a few tenths of an angstrom unit.
