What is 'v' here? You have to return 'res' as value for the key 'value'.

def onchange_ma_nv(self, cr, uid, ids, ma_nv, context = None):
         res = {}
         if ma_nv:
             ma = self.pool.get('danh.sach.nv').browse(cr, uid , ma_nv, context = context)
             res= {
                   'ten_nv': ma.ten_nv,
                   'luong_ct': ma.luong_ct
                 }
         return {'value': res}

No limit in return type in onchange function. It return dictionary with no of keys (is the column name) and values.
