A two-fluid model of turbulence is presented and applied to predictionsof the intermittency of turbulent free jets. 本文闡述湍流的雙流體模型，并用于計算湍流自由射流的間歇性。
The characteristics of chaos, are that positive characteristic exponents and fractional dimension can quantitatively express the turbulent intermittency. 正的特征指數(shù)和分數(shù)維可以定量表征湍流的間歇性。
It is assumed in the two-fluid model that the turbulent and non-turbulent fluids occupy the turbulent flow field intermittently and thus the"intermittency"phenomena of turbulence are simulated. 二流湍流模型假設湍流流場中的每一點為“湍流”和“非湍流”流體所交替占據(jù)，從而模擬了湍流的“間隙”現(xiàn)象。
