用电学和热学方法测量了美国超导公司生产的双层第二代高温超导线材的正常区传播速度（NZPV），并对测量结果进行了比较和讨论。由电压迹线确定的NZPV值的范围为3.8 mm/s（0.4 Ic）至19.2 mm/s（0.9 Ic），而由温度迹线确定的NZPV值的范围为5.9至18.3 mm/s。两种方法确定的NZPV值吻合较好。双层YBCO超导带材的NZPV接近于传统单层超导带材。
The Normal zone propagation velocity (NZPV) of a double-layer second generation high temperature superconducting wire manufactured by American Superconductor has been measured by electrical and thermal methods, and the results have been compared and discussed. The NZPV values determined by the voltage traces are ranging from 3.8 mm/s at 0.4 Ic to 19.2 mm/s at 0.9 Ic; while from 5.9 to 18.3 mm/s by the temperature traces. NZPV determined by these two approaches agrees well with each other. Also, NZPV of double-layer YBCO tape is close to that of conventional single-layer superconducting tape.
