摘　　要：在伴有右手中中微子的SU(3)c(?)SU(3)l(?)U(1)X(331)模型框架内讨论了Higgs粒子产生过彻e+e-→ZH.结果表明,当新粒子Z'的质量接近质心能量时能对该过程产生明显的修正.在该模型合理的参数空间内,过程e+e-→ZH的总产生截面σ与标准模型(SM)相应值的偏差大于5%,应该能在未来的高能直线对撞机实验中观测到。In the context of SU（3）C×SU（3）L×U（1）X（331） model with right-handed （RH） neutrinos, we study the Higgsstrahlung process e^＋e^-→ ZH and calculate the cross section of this process at leading order. Our numerical results shown that the production cross sections for this process can be significantly large as MZ＇-√s. With reasonable values of the Z＇ mass MZ＇, the deviation of the total production cross section σ^101 from its SM value is larger than 5%, which might be detected in the future high energy linear e^＋e^- collider （LC） experiments. The future LC experiments could test the 331 model with RH neutrinos by measuring the cross section of the process e^＋e^-→ ZH.
