https://drupal.stackexchange.com/questions/69684/how-to-assign-value-from-one-file-field-to-another-programmatically根据这里，我添加display = 1
$field_file = (array) $file;
$field_file['display'] = 1;
dpm($file,'field_pr_ref_quotation_file');
$node->field_pr_ref_quotation_file[LANGUAGE_NONE][] = $field_file;
