摘要：

For　the　purpose　of　promoting　the　practicality　of　magnetic　refrigeration　technology　in　China,　a　systematic　presentations　of　the　Gd5(SixGe1-x)4　inter-metallic　compounds　was　given,　which　possessed　the　best　magneto-caloric　effect　among　all　magnetic　refrigerant　materials　at　room　temperature.　In　this　paper,　the　relationships　between　the　magneto-caloric　effect　and　the　crystal　structure　as　well　as　phase　transition　was　clarified;　furthermore,　several　effective　ways　to　improve　the　magneto-caloric　properties　of　the　alloys　in　recent　studies　were　recommended.　Some　problems　and　solutions　for　the　applications　of　the　alloys　in　the　near　future　were　also　discussed.
