isobaric cooling

The granulite facies were resulted from the regional high-temperature metamorphism with medium pressure. The metamorphism evolution was the retrogressive metamorphism with approximate isobaric cooling ( IBC) and counter clockwise PTt path.

麻粒岩相是中压区域高温变质作用的产物，变质作用的演化为退变质、近等压冷却（IBC）反时针型的PTt轨迹。

The rate of change of δ 18O against temperature in the process of wet adiabatic cooling is smaller than in the process of isobaric cooling under the same humidity.

在相同的湿度条件下，湿绝热冷却过程中δ18O随温度的变化率小于等压冷却过程。

The global MWL lies between the two MWLs simulated under wet adiabatic and isobaric cooling processes, respectively.

全球大气水线位于湿绝热冷却过程和等压冷却过程条件下分别模拟的两条大气水线之间。
