查询词典 fluids

Firstly, according to the relationship between classic Carnot cycle and Lorenz cycle, the paper evaluates the cycle characteristics and thermodynamic properties of NARMS (Non-azeotropic mixtures), and compares the energy-saving difference between pure and mixed refrigerants. The main of factors that affect heat pump operating efficiency are analyzed in theory and using the Second Law of Thermodynamics the exergy are evaluated in components of heat pump system, in the end a conclusion is drew that all of the exergy have bearing on working fluids' properties.

本文首先从经典的Carnot逆循环与Lorenz逆循环相对关系出发，评估了非共沸混合工质循环的特点以及热力学性质；在不同环境条件下，比较了单工质与混合工质的循环特性差异；针对非共沸混合工质热泵循环效率的主要影响因素（即工质本身的热物性和系统部件特性）进行了理论分析，并利用热力学第二定律对热泵系统的各个主要部件进行了可用能分析，最终发现每一处可用能损失均与工质物性有关；在此基础上提出了减少可用能损失的方法—寻找适宜的非共沸混合工质。

Intravenous fluids containing potassium (e.g., lactated Ringer's solution) should be avoided.

应避免含钾的静脉输注液。

In the United States, chronic alcoholism and hepatitis C are the most common ones.

在美国，慢性酒精中毒，肝炎是最常见的。
