摘要
投影机的参数虚标问题已成为公开的行业秘密。如果使用单位只通过厂商人员的产品介绍推荐,或书面的产品性能技术指标描述选定机型,极易导致使用单位在价格、使用效果和质量上的受损状况。因此,在批量添置投影机时,要取得货真价实,实用效果好的机型,必须根据用途要求,确定档次后,对几个品质较好的品牌投影机的主要性能指标进行直观测试。以测试结果及报价为依据,决定招标的入围机型,合理选择采购方式,以保证使用效果及经济效益。
It＇s an open trade secret that the parameters of projectors on the market are always false labeled. Dealers＇ introductions or the written descriptions of the product performance are not enough for the purchasers to make a correct judgment on the price, quality and effeets. Therefore, when buying a large number of projeetors with reasonable priee as well as good quality, purchasers should direedy test the performance of projectors of several brands with good reputation. Only according to the result of the real test together with the eomparison of the priees, eould the purchasers make the deeision.
