我们在临界点（Z*）处的有效压缩系数和单位压缩线（Zeno线）参数之间设置了新的规律。对于经典液体，Z* 是普通压缩因子 Z(c)，但对于量子液体，Z* 取决于德波尔参数。结果，我们表明，具有经典热力学性质的大量真实物质的 Z(c) < 0.32。经典汞和量子 H(2)、He(4) 和 He(3) 的 Z(c) 或 Z* > 0.37。利用实验获得的液气共存曲线的低温部分，我们可以找到金属（Al、Cu、W、U和Zr）的临界参数，这些参数是事先未知的，并且处于实验无法获得的参数范围内。
We set new regularities between the effective compressibility factor at the critical point (Z*) and unit compressibility line (Zeno-line) parameters. For classical liquids, Z* is the ordinary compressibility factor Z(c), but for quantum liquids Z* depends on the de Boer parameters. As a result, we show that a wide group of real substances with the classical thermodynamical properties has Z(c) < 0.32. Classical mercury and quantum H(2), He(4), and He(3) have Z(c) or Z* > 0.37. Using the low temperature part of the liquid-gas coexistence curve obtained from experiment, we can find the critical parameters for metals (Al, Cu, W, U, and Zr) for which these parameters are unknown in advance and lie in the domain of parameters still inaccessible for experiment.
