根据惠更斯-菲涅耳原理，推导出CBIL换能器声场的解析近似表达式，并给出CBIL换能器声束宽度的表达式。与数值积分计算结果及实测结果进行了比较，结果表明三者之间的误差甚小。对实际应用来说，这个解析解的精度已经足够。显然，解析解具有计算量小，易于对物理机制和影响因素进行分析的优点。

In this article， an analytical description for the acoustic wave field of the CBIL transducer is derived based on Huygens－Fresnel principle． The expression for the beam width of CBIL transducer is also presented． Compared with the results of the numerical integral calculations and the measurements， it is found that the differences among them are very small． The precision of the analytical solution is good enough for practical application． Apparently， the analytical method has the advantages of less computation and is easy to analyze the physical mechanism and influence factors．
