This paper introduces a temperature acquisition system that can accurately measure and control the temperature of liquid nitrogen and liquid helium. 从硬件和软件上设计了一套可以精确测量和监控液氮(LN)温度和液氦温度的温度采集系统。
Experimental studies were made in Josephson effect of bulk superconductive materials at liquid nitrogen temperature. 本文对液氮(LN)温区的大块体超导材料的约瑟夫逊效应进行了实验研究。
We destroyed the nest with liquid nitrogen. 我们用液态氮摧毁了那个窝。
They fill the container with pure air made by evaporating liquid nitrogen and liquid oxygen, and add water vapour and some trace gases. 他们往云室里填充了由液态氮和液态氧经气化后制成的纯净空气,并添加了水汽和一些痕量气体。
Meanwhile, simple heat-capacity economical analysis and calculation of liquid nitrogen are conducted. 同时对液氮(LN)冻结能力进行粗略的热力经济分析与计算。
