书院门改造方案

书院是我国古代的一种教育机构。它既非官学，也不同于一般私塾与义学等私学，而是在继承改造传统教育经验的基础上，开创的一种社会办学的独特体系制度。但不管怎么说，书院就是一个各种思想相互碰撞、相互交融的场所。

FMS Scheduling Simulation Based on an Evolution Algorithm

A FMS（flexible manufacturing system) scheduling algorithm based on an evolution algorithm (EA) is developed by intensively analyzing and researching the scheduling method in this paper.Many factors related to FMS scheduling are considered sufficiently.New explanations for a common kind of the encoding model are given.The rationality of encoding model is ensured by designing a set of new encoding methods,while the simulation experiment is performed.The results show that a FMS scheduling optimum problem with multi-constraint conditions can be effectively solved by a FMS scheduling simulation model based on EA.Comparing this method with others,this algorithm has the advantage of good stability and quick convergence.

Pt/H-SAPO-11催化剂用于重质油催化转化研究初探

应用SAPO—11分子筛负载Pt制备Pt／H—SAPO—11催化剂。以糠醛精制后的丙烷脱沥青油150BS为反应介质，在20mL催化加氢反应装置上对Pt／H—SAPO—11催化剂进行评价。考察在反应压力14．5MPa，氢油体积比700，质量空速1.35h^—1，不同反应温度条件下反应产物的收率及大于370℃润滑油馏分凝点和粘度指数的变化。结果表明，小于200℃馏分油，200-315℃轻质燃料油馏分，315—370℃轻质润滑油馏分，以及大于370℃润滑油混合馏分等液体总收率保持在90％左右。大于370℃润滑油混合馏分的凝点可达-15℃，粘度指数为107。

对山西省煤炭就地转化和合理利用的几点建议

<正> 山西省煤炭资源丰富,开采条件好,煤产量仍将不断增长,但目前煤的外运主要靠铁路,受运输条件的限制,每年积压的煤量达几千万吨。随着煤炭产量的不断上升,预计煤的积压量也将有增无减。对这些已开采出来不能外运的煤炭,必须就地加以转化和利用,否则因长期堆放会造成自燃,不但浪费了煤炭资源,也造成环境污染。现提出以下几点近期煤转化和利用的建议。
