摘　　要：为了避免宽带匹配中的不精确设计,提出了宽带匹配设计公式的择优性以及切比雪夫多项式匹配极限情况与二项式匹配的等价性。通过理论推导和案例设计证明了择优性和等价性的正确性,最后结果表明宽带匹配的这两个性质对提高设计精度和加深对宽带匹配理解有着积极的意义。For avoiding the inaccurate design about broadband match, the optimization of equation selection in the design of broadband match and the equivalence between Binomial match and Chebyshev match under certain circumstance is presented. The optimization and equivalence is testified by mathematical reduction and.examples design, and it turns out these two properties would be conducive to engineers to improve the precision of design and deepen their understanding on broadband impedance match.
