THE COMEDY

A Critieism of the "Divine Comedy" of Dame Alighieri Translated from theItalian of Francesco di SanetisAny one who has followed me will have seen that the Divine Comedywas not a new, original. or extraordinary idea sprung from the mind of Dameand thrown into the midst of a marvelling world. Rather its importance lay inthat it was everybody's idea, the thought that was lying at the bottom of all theliterary forms: legends, visions, treatise. treasures, gardens, sonnets and canzoni.The Alle…     

Epitypification： should we epitypify？

Epitypification can solve many taxonomic problems and stabilize the understanding of species, genera, families or orders. The aim of this paper is to illustrate how to epitypify. A few examples where taxa have been epitypified are considered and the benefits and disadvantages of epitypification are discussed. We also outline some examples of taxa which need to be epitypifled with reasons.     

用分子计算

计算机的速度能够达到多快?功能可以有多强大?可不可能有这么一天，人们创造出的人工“大脑”的智力与人类大脑相当——甚至优于人类?这些问题的答案在很大程度上以一个因素为基础，而这个因素就是：我们能够制得多小尺寸的计算机电路，以及能达到多大的集成密度。     

黄河淤泥沙烧结空心砖技术推广

一、前言 当前,我国的墙改工作方兴未艾,我省我市也正如火如荼地展开。我国人多地少,土地资源十分紧张,而目前仍有7000亿块粘土实心砖的生产,毁掉大量耕地;另一方面,我国人均能源资源占有率低,能源危机十分严重,而建筑能耗占民生总能耗的27％以上.因此国家把墙改和建筑节能工作摆在重要位置,视为可持续发展战略的重要一环。空心砖是一种性能优

玉米六种耕作方式灰色评估及其效益分析

针对山西旱地面积大，干旱、地薄是制约农业生产的主要限制因素，为探索粮食生产作物玉米增产的技术新途径，分别在不同生态区设点，对六种不同耕作方式的试验结果进行灰色评估，量化处理，其结果证明，免耕整秸秆半覆盖为最佳耕作栽培方式，具有显的蓄水保墒，增肥改土，增产增收效益。     

Simulation Modeling by Fuzzy Nets

Fuzzy technology is a newly developed discipline based on fuzzy mathematics. In the recent years, it has been successfully applied into many areas, such as process control, diagnosis,evaluation, decision making and scheduling, especially in simulation where accurate mathematical models can not or very hard be established. In this paper, to meet the demands of fuzzy simulation, two fuzzy nets will first be presented, which are quite suitable for modeling the parallel or concurrent systems with fuzzy behavior. Then, a concept of active simulation will be introduced, in which the simulation model not only can show its fuzzy behavior, but also has a certain ability which can actively perform many very useful actions, such as automatic warning, realtime monitoring, simulation re-sult checking, simulation model self-adapting, error recovery, simulating path tracing, system states inspecting and exception handling, by a unified approach while some specified events occur. The simulation model described by this     

Study on the System Design of Multiple Expert Systems Integrated Decision Support System

There has been an increasing interest in integrating decision support systems (DSS) and expert systems (ES) to provide decision makers a more accessible, productive and domain-independent information and computing environment. This paper is aimed at designing a multiple expert systems integrated decision support system (MESIDSS) to enhance decision makers' ability in more complex cases. The basic framework, management system of multiple ESs, and functions of MESIDSS are presented. The applications of MESIDSS in large-scale decision making processes are discussed from the following aspects of problem decomposing, dynamic combination of multiple ESs, link of multiple bases and decision coordinating. Finally, a summary and some ideas for the future are presented.

Probing the Intact Cluster Catalysis Concept by Tetrahedral Clusters With Framework Chirality

In order to bring evidence for or against the hypothesis of catalytic hydrogenation by intact trinuclear arene ruthenium clusters containing an oxo cap, the substrate being hydrogenated inside the hydrophobic pocket spanned by the three arene ligands （“supramolecular cluster catalysis”）, we synthesized cationic Ru30 clusters （See Fig. 1） with three different arene ligands （intrinsically chiral tetrahedra）.
