简述狭义招标采购与广义招标采购的含义。

答案

参考答案:

解析:招标采购有广义和狭义之分,其含义分别如下: (1)狭义招标采购的含义 狭义的招标采购是指招标人根据自己的需要提出一定的标准或条件,向指定投标商发出投标邀请的行为过程,即邀请招标或选择性招标。 (2)广义招标采购的含义 广义的招标采购是指招标人发出招标公告或通知等公开程序,邀请潜在的投标商进行投标,最后通过对各投标人提出的规格、质量、交货期限及该投标企业的技术水平、财务状况等因素进行综合比较,确定其中最佳的投标人为中标人,并与之签订合同的过程。 招标竞价方式对于采供双方而言,增加了透明度,真正体现市场竞争优胜劣汰的原则,从而达到保证物料采购质量,降低产品总成本,提高经济效益,客观上也杜绝了腐败现象的目的。

For nearly a century before there was such a thing as a space program,a view of space was possible.People could see full views of the Moon,explore Mars(探测火星),and study the outer space beauty.All of this was made possible by a small group of artist-astronomers(天文艺术家) who worked to show people how other worlds in space might look.

Lucien Rudaux,a French artist,was the first to use his artistic ability and his knowledge of astronomy in art.His paintings show a mixture of skilled observations,brilliant imagination and careful attention.As a result,many of his works have come surprisingly close to actual conditions on distant planets.His painting of Mars included moonlike craters(火山口) that were first photographed by the astronauts in 1965.His 1930 painting of a dust storm looks remarkably like a photograph of a storm taken by the astronauts in 1976.

The artist-astronomers,including Rudaux,made people interested in outer space by painting what turned out to be exact portraits of the planets.
