摘　　要：为了弥补经典的条件性不稳定判据①理论的局限性，笔者根据近年来采用的对流性不稳定判据［１］建立了一个既可上机计算，又可在Ｔ－ｌｎｐ图上操作的“θｓｅ递减率公式”．作为“公式”的理论检验和应用，笔者选取了大连冬季两个典型例子进行了判断和分析。In order to make up the limitations of the classical condition unstable criterion theory, the authors, according to the convection unstable criterion used in recent years, put forward a θ se lapse rate formula, which can either be used on a computer or operated on a T ln p chart. As an exam of the theory and applications of the formula, the authors took two successive typical examples of Dalian winters to make a judgment and analysis, the results will conformed with the observations.
