摘　　要：在利用反应体系说明压强对化学平衡影响的实验中，当推压活塞时，体系将出现由浅→深→浅的颜色变化．就这种色变产生的原因，本文提出了新的解释，即主要是由于体系的温度变化所致．并由此阐明该实验不适宜说明压强化学平衡的影响．There is a test by using the chemical reaction system N2O4→2NO2 to show how thechemical equilibrium is affected by pressure intensity. In this test, colour changes fromlight colour to deep colour and then light will appear in the system when the piston ispushed forward. On the cause of the colour changes appearing, the writer has advanced anew explanation in the thesis, Or it is mainly caused by the temperature. So the writer eapounded that the test is not appropriate to show how pressure affect chemical equilibrium.
