If lists are intended to be used, it is preferable to develop lists of items not suitable for acquisition through electronic reverse auctions or, alternatively, to list generic characteristics that render a particular item suitable for acquisition through this purchasing technique.
如果计划使用这类清单，就应当拟定不宜通过电子逆向拍卖进行采购的货物清单，或列举不宜使用这种采购方法进行采购的特定货物一般特征。
