The plastic door and window have near 20 years of hist ory in China.

塑料门窗在我国的研究与应用已有近2 0年的历史，但与国外的塑料门窗行业相比，国内的自主开发能力较为薄弱，目前国产型材在结构的合理性和功能的先进性方面要低于国外同类产品。

The homogeneous calibrator and ideal material calibrator are considered respectively. From the optimal results" analysis and comparison, we can see that the ideal material calibrator improves greatly the cooling uniformity of plastic profile by changing the cooling channel"s location, size, number and adjusting calibrators material distribution.

分别考虑均质定型模和理想材料定型模，从优化结果分析、比较可以看出，理想材料定型模通过改变冷却水道的位置、尺寸和数量以及调整其材料分布规律，极大地改善了塑料型材的冷却均匀性和冷却效率。

Following the development of our economic, the need of the oversized section bar is on the rise in many fields.

随着我国经济的发展，各个领域对特大型型材的应用将会呈不断增长趋势。

Location-inventory system integrated design problem under stochastic demand The location-inventory distribution system design problem involving one supplier, candidate distribution centers and multiple retailers under normal distribution demand is studied in the background of building materials industry. Retailers adopt periodic reviewinventory policy, while distribution centers adopt continuous reviewinventory policy. Considering the trade-off between inventory cost, shipping cost and facility location cost, the integrated 2-echelon inventory control policies with incapacitated facility location model is presented.

随机客户需求下的选址-库存集成问题研究：以满足正态分布客户需求的型材配送物流为研究背景，研究了由单供应商、候选分拨中心和分销点构成的配送物流系统集成规划问题，分销点、分拨中心分别采用周期检查和连续检查库存控制策略，综合考虑库存成本、运输成本和设施成本之间的均衡关系，建立了二级库存控制策略与无能力约束选址集成规划模型。

Suggestion: the owner in enough gauze portiere when see the intensity, because in the thickness of the profile has the very big difference.

建议：业主在选够纱门窗时看一下铝合金的强度，因为在型材厚度有很大的区别。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
