分析了湿空气状态参数间的关系,给出了含湿量、比焓的比长度定义,介绍了两点作图法、角度尺量法两种确定热湿比线的作图法。根据坐标系中坐标的表示方法及正弦定理和热湿比的定义,论证了常用焓湿图热湿比与热湿比线和等含湿量线之间夹角间的关系,并以此作为角度尺量法确定热湿比线的理论依据。举例说明了两点作图法、角度尺量法的应用,对比了两者的优劣,结果表明两点作图法确定热湿比线更方便快速。
分析瞭濕空氣狀態參數間的關繫,給齣瞭含濕量、比焓的比長度定義,介紹瞭兩點作圖法、角度呎量法兩種確定熱濕比線的作圖法。根據坐標繫中坐標的錶示方法及正絃定理和熱濕比的定義,論證瞭常用焓濕圖熱濕比與熱濕比線和等含濕量線之間夾角間的關繫,併以此作為角度呎量法確定熱濕比線的理論依據。舉例說明瞭兩點作圖法、角度呎量法的應用,對比瞭兩者的優劣,結果錶明兩點作圖法確定熱濕比線更方便快速。

Analyses the relationship between state parameters of wet air,gives the definitions of the length to unit humidity and unit specific enthalpy,and presents two angle scale line drawing methods of two points and using angle measurement.According to representing method of coordinates in oblique coordinate system and the law of sine and the definition of angle scale,demonstrates the relationship between an angle scale and the angle between the angle scale line and an isohume on a common psychrometric chart,and takes it as the theory basis of drawing an angle scale line with angle measurement method.Illustrates the application of the two drawing methods of two points and using angle measurement,and compares the advantages and disadvantages of the two methods.The result shows that with the two point method can conveniently and quickly draw an angle scale line on a psychrometric chart.
