The vapour pressure-temperature relationship has been determined for commercial high-purity nitrogen from the triple point down to 45 K; this data conforms to the expression log 10P = 7.614676 356.281/T to within a 1% pressure deviation. A value of 63.148 K has been deduced for the triple ...
摘要: The vapour pressure of liquid nitrogen has been measured between 176°C and 148°C. The results are represented as a function of temperature by a formula, containing four constants.DOI: 10.1016/S0031-8914(53)80003-0 被引量: 73 ...

Denitrification in sediment determined from nitrogen isotope pairing Abstract A new method for accurate and easy measurement of denitrification in sediments is presented. The water overlying intact sediment cores was enriche... LP Nielsen - 《Fems Microbiology Letters》 被引量: 1033发表: 1992年 ...
0.98. In general, however, the accuracy of the adsorption measurement decreases as the equilibrium pressure approaches to the saturated vapor pressure, because the liquid nitrogen temperature would fluctuate following the variation in atmospheric pressure. For safety one would better understand the upper ...
