按照《五金交电家电化工商品的购销合同实施办法》规定，供方错发到站、中转单位、收货单位

铝合金的防腐性能好是因为很难被氧化。

随着社会经济的发展和施工技术的进步，现代工程建设呈现出建设规模不断扩大、技术复杂程度高等特点。近年来，出现了大量建筑规模较大的单体工程和具有综合使用功能的综合性建筑物，几万平方米的建筑比比皆是，十万平方米以上的建筑也不少。由于这些工程的建设周期较长，工程建设中可能会出现建设资金不足，部分工程停、缓建，已建成部分提前投入使用或先将其中部分提前建成使用等情况，再加之对规模特别大的工程一次验收也不方便，等等。因此标准规定，可将此类工程划分为若干个子单位工程进行验收。同时为了更加科学地评价工程质量和验收，考虑到建筑物内部设施也越来越多样化，按建筑物的主要部位和专业来划分分部：工程已不适应当前的要求。因此在分部工程中，按相近工作内容和系统划分为若干个子分部工程。每个子分部工程中包括若干个分项工程。每个分项工程中包含若干个检验批，检验批是工程施工质量验收的最小单位。
[问题]1．建设工程施工质量的验收，主要通过哪几个层次的验收
2．各层次的质量验收记录由谁填写由谁组织哪些人员进行验收
3．工程施工质量不符合要求时，应按什么规定来确定是否验收

     The desire to make explorations is born with man. Wherever his imagination goes, man also has a strong

wish to go. A large part human history is connected with the exploration of the world in which we live. Again

and again people have set out with surprising courage and patience to look into unknown regions and lands to

see what had not yet been seen, to make known the unknown. With kites, balloons and aircraft they left the

ground to pass through the lower atmosphere. Now the outer space receives their attention.

     Why should man take the trouble of conquering space? It is hard to list the specific practical benefits that

will result in. But one knows, from past experience in other areas, that man will surely see and discover new

things in space that will increase our scientific knowledge, and this new knowledge will find its way into

valuable practical uses. What we learn about man himself, from his experience in space, and from the effects

of space and the space flight environment on him, will be extremely valuable. The new techniques developed

to carry out the exploration of space, and to keep man alive in space, will certainly find practical uses in

everyday life in some way. The areas that will benefit are manifold. They include communication, generation

of power, transportation and travel, food production, materials, fuels and many others. But to say definitely

just what the practical results will be is almost impossible.
