在热原子束中利用锶原子互组跃迁塞曼子能级构成的V型能级结构，通过荧光观测实验研究了互组跃迁中的原子相干效应。对互组跃迁简并能级构成的V型能级结构的电磁诱导透明(EIT)效应进行了理论计算，且详细分析了耦合光失谐、线宽和拉比频率对互组跃迁EIT效应的影响。实验测量了不同耦合光失谐和功率条件下的互组跃迁电磁诱导透明效应。

The atomic coherence effect is investigated experimentally in the thermal strontium atomic beam by means of fluorescence observing, based on the V-type Zeeman-sublevel system of intercombination line of Sr. A theoretical calculation of the V-type electromagnetically induced transparency (EIT) has been elaborated, taking into account the effect of detuning, linewidth and Rabi frequency of the coupling laser on intercombination transition EIT. The V-type electromagnetically induced transparency of intercombination is measured experimentally under different condition of detuning and with different powers of the coupling laser.
