But through the investigation we find that the contact between the national members take the economic exchange as their suppert.Third,the Huis and Hans have positive and stable attitude toward inter-ethnic contacts in the psychological scale ,such as colleagues,group ,neighours and making friends.But the upgrade of their religious beliefs,the Huis have a high congnition in the national consciousness and the national identity .The Huis and the Hans have a high sense of identity in the same sex in the contacts by the impact of the traditional Chinese culture and the division model .Regard to the deep-seated inter-ethnic-marriage contact,members of the Huis and Hans have certain reservations .Especially,the Huia have the attitude because of the religion belief .

第三，在交往的心理尺度上，回汉民族的交往态度积极稳定，对民族间日常的交往，如同事、团体、经济、做邻居及其交友方面都有很高的积极态度，但同时由于宗教信仰对于民族意识(来源：A82B2f66C论文网www.abclunwen.com)和民族认同、情感方面的提升作用，回族对民族交往的民族身份有很高的认同；受中国传统文化和分工模式的影响，回汉民族成员对交往的同性别对象有很高的认同感；对于民族间的深层次交往——婚姻交往，回汉民族成员都有一定的保留，尤其是回族对于宗教信仰的崇敬，比较反对回汉之间的通婚，汉族也因生活习惯的差异对族际通婚持保留态度，心理距离相对较远。
