摘　　要：目的:对两种机器运用于大脑语言认知能力实验进行对比研究,同时对词组作为大脑语言认知能力实验材料的可行性进行探讨。方法:选取7名不同被试者,运用1.5T Siemens Symphony与1.5TGE SI-GNA磁共振成像机器,分别使用不同的现代汉语四字词组作为语言认知刺激材料进行脑功能成像扫描。结果:大脑激活图显示两种型号机器在进行语言认知能力实验时有比较好的一致性,二者之间存在的差异是由实验材料造成的。结论:不同的实验材料、不同机器有不同的激活脑区,但是总体位置,尤其是公认的语言区激活明显,也与以前的研究一致,说明fMRI实验的可重复性比较高。Objective To compare the difference of application of the two machines in language cognitive research and to disscus the feasibility for the phrase as the examination materials in brain language cognitive research. Methods：Seven 7 volunteers were chosen and different four Chinese words were used as the language cognitive stimulative materials, with 1.5 T Siemens Symphony and 1.5 T GESIGNA magnetic resonance machines in brain functional scan. Results：The brain activity showed much correspon- dence between the two machines in language cognitive research. The differences between them were due to stimulative materials. Conclusion：fMRI can be used in researching the brain areas in different language stimuli. And it is possible that the four words phrase as the language cognitive stimulative materials can be used in brain language cognitive research.
