Measurements of the temperature distribution of liquid nitrogen contained in 15 and 7.5 cm diameter dewars show that the bulk of the liquid is at an approximately constant temperature .15 to .3 K above the surface temperature. About half the liquid in the dewar is in a superheated state and ...
3) liquid nitrogen temperature 液氮温区 1. Based on a temperature sensing model of FBG,a temperature sensing experiment is conducted at liquid nitrogen temperature(-196 ℃). 文章从光纤光栅的温度传感模型出发,理论分析了光纤光栅的温度传感特性,完成了在液氮温区(-196℃)的温度测量。 更多例句>> ...
The first step of the membrane cleaning is choosing the appropriate cleaning agents, which often entails a trial-and-error approach. Several reports describe the cleaning procedures using acid, alkali, high temperature, enzymes, and hypochlorite, and many membrane suppliers recommend sodium hypochlorite ...
To analyze the thermodynamic effect of cavitation effects in the same cavitation number and the same boundary conditions, isothermal and temperature were calculated under the conditions of liquid nitrogen cavitation hydrofoil. 翻译结果2复制译文编辑译文朗读译文返回顶部 To analyze the thermodynamic effect of...
Temperature is one of the critical factors affecting rice growth and yield production. This study investigated the effects of rhizosphere temperature at the tillering stage on the growth, physiological parameters and gas exchange attributes of two rice cultivars, i.e., the super rice cultivar Yuxiang...
After seeding, the temperature was lowered to −30°C at the slow rate of −0.3°C/min and then down to −150°C/min at the rapid rate of −50°C/min. The straws were then transferred to liquid nitrogen for storage. 1.3. Endometrial preparation, blastocyst thawing, and transfer ...

Compared to the Chukchi Shelf, an obvious stratification of the water column over the Bering Shelf could be seen, although bearing roughly the same temperature and salinity (Fig.3b, c). Hydro-chemical measurements are also within range of the measurements made of the Chukchi Shelf water, except...
rate of asphaltene film formation at the interface25,26,27. Moradi and Alvarado26studied the influence of the temperature on the kinetics of asphaltene film formation. They inferred that the asphaltene particles move towards oil–water interface up to 2 times quicker when the temperature is ...
Current mitigation efforts and existing future commitments are inadequate to accomplish the Paris Agreement temperature goals. In light of this, research and debate are intensifying on the possibilities of additionally employing proposed climate geoengineering technologies, either through atmospheric carbon dioxi...
