对R1233 zd（E）和R1224 yd（Z）的临界参数进行了实验测定，通过目视观察弯月面。第一次测量是对R1224 yd（Z）进行的，以验证本工作中使用的实验装置和程序，第二次测量是对R1233 zd（E）进行的，以解决该制冷剂公布的临界温度的差异。成功地确定了两种制冷剂的临界参数; R1224 yd（Z）的临界温度、密度和压力的最终值分别为428.82±0.03 K、540.8±7.0 kg· m-3和3327±7 kPa，R1233 zd（E）的临界温度、密度和压力的最终值分别为438.86±0.03 K、486.7±5.2 kg· m-3，3558± 7kPa。利用本文得到的R1233 zd（E）的临界参数，建立了一个新的基本状态方程。
The experimental determination of the critical parameters was performed for R1233zd (E) and R1224yd (Z) by the visual observation of the meniscus. The first measurement was made for R1224yd (Z) to validate the experimental apparatus and procedure used in this work, and the second measurement was carried out for R1233zd (E) to resolve the discrepancy in published critical temperatures of this refrigerant. The critical parameters of both refrigerants were successfully determined; the final values for the critical temperature, density, and pressure of R1224yd (Z) were 428.82±0.03 K, 540.8±7.0 kg· m− 3, and 3327±7 kPa, respectively, and those of R1233zd (E) were 438.86±0.03 K, 486.7±5.2 kg· m− 3, and 3558±7 kPa, respectively. The critical parameters of R1233zd (E) obtained in this work were adopted in the development of a new fundamental equation of state.
