老顶山人工油松林生物量的研究

对海拔１２００—１３００ｍ处的２８年生油松人工林生物量进行了研究。乔木层的生物量采用回归模型预测，其为：油松Ｗ树干＝２．３１６（Ｄ２Ｈ）０．６５８，Ｗ（枝条）＝１．３１３（Ｄ２Ｈ）０．９８９，Ｗ叶子＝１．４１２（Ｄ２Ｈ）０．８３１和Ｗ（根条）＝１．５８９（Ｄ２Ｈ）０．７５３，灌木和草本植物用表测数据计算。结果表明：６月份人工油松林的总生物量为４３．４７０ｇ／ｈａ，其中乔木层３５．６７９吨／公顷，林下灌木及草本层７．７９１ｔ／ｈａ。     

徐淮平原农田防护林带杨树根系特征研究

主要研究徐淮平原农田防护林带林木根系分布特征，结论如下：①在道路和沟坡上，随着离根株距离的增加，根系生物量和长度急剧下降；根株附近大根所占比率较高，而较远处细根所占比率较高。②道路土壤中细根相对较少，而农田中较多。③无论在农田还是在道路中，根系主要分布在０￣４０ｃｍ土层内；但路边大根分布深。     

柴油机连杆塑性成形高向充填的研究

用塑性变形理论对柴油机连杆辊轧成形的变形过程及变形特点进行了分析，阐明了辊轧连杆时存在着高向充填的难易成形区，并进行了实验验证，找出了解决高向充填不足的途径与方法。     

膨润土在高水材料凝固硬化中的作用

研究了膨润土在高水材料凝固硬化中的机理。由于膨润土在水中易分散为大量极微小的薄片，与棱柱状水化产物ＡＦｔ一起构成絮凝结构网，封闭自由水，促使浆体凝固。絮凝结构形成后，膨润土因防碍晶体连生而对强度发展不利。     

RESEARCH ON REUSE OF PAPERMAKING LIGNIN-CONVERSION OF LIGNIN TO BTX BY CATALYTIC PYROLYSIS IN A POWDER PARTICLE FLUIDIZED BED

INTRODUCTIONPlant consists essentially of three main polymers:lignin, cellulose, and hemicellulose, which are themost abundant and renewable hydrocarbon resourceson the earth. The annual yield of rice straw, wheatstraw, bagasse, reed, and bamboo in our country hasexceeded 1 billion tons. 30% of the yield of ricestraw and wheat straw are used for papermaking, which occupy 70-80% of the raw material. However, it is the difficulty in papermaking waste liquid treatment as well as the lack of c…     

Debunking material induction

In this paper, we present an explanatory objection to Norton's material theory of induction, as applied to predictive inferences. According to the objection we present, there is an explanatory disconnect between our beliefs about the future and the relevant future facts. We argue that if we recognize such a disconnect, we are no longer rationally entitled to our future beliefs.     

Between meaning culture and presence effects: contemporary biomedical objects as a challenge to museums

The acquisition and display of material artefacts is the raison d’être of museums. But what constitutes a museum artefact? Contemporary medicine (biomedicine) is increasingly producing artefacts that do not fit the traditional museological understanding of what constitutes a material, tangible artefact. Museums today are therefore caught in a paradox. On the one hand, medical science and technologies are having an increasing pervasive impact on the way contemporary life is lived and understood and is therefore a central part of the contemporary world. On the other hand, the objects involved in medical diagnostics and therapies are becoming increasingly invisible and intangible and therefore seem to have no role to play as artefacts in a museum context. Consequently, museums are at risk of becoming alienated from an increasingly important part of contemporary society. This essay elaborates the paradox by employing Gumbrecht’s (2004) distinction between ‘presence’ and ‘meaning’.
