本文介绍了采用外部吹冷气和中心阱用金属棒冷却相结合的诱导凝固技术,实现锡凝固点的新方法。该新方法实现的锡凝固点与国家基准锡凝固点温度之差小于1mK。实验证明,新法具有操作简单且能获得很平坦的温坪等优点。
This paper introduces a new method to realize the solidification point of tin by inducing and solidifying technology which combines the external air-cooling with the cooling of the central well by the metal rod. The difference between the tin solidification point and the national reference tin solidification point temperature achieved by the new method is less than 1 mK. Experiments show that the new method has the advantages of simple operation and can obtain very flat Wen Ping.
