【摘要】该文以漏热法测量比热容;真空系统配用低温冷凝泵;测量电路配用“长江—Ⅰ”微机程控,实现自动测量、记录和运算。对Cu和YBaCuO样品进行了测量,其结果与文献相吻合。更多还原

【Abstract】 Specific heat measurements were performed in the method of non-balance. The vacuum system is equipped with low-temperature condensation-pump. With a microcomputer “Chang Jiang-I” connected to the experimental circuit, data can be recorded and calculated automatically. Measurements on Cu and YBa2Cu3O7 were made. The results are consistent with the references.更多还原
