半导体光催化模拟光合磷酸化研究--单色(绿)光对ATP合成的影响

以半导体材料（Zn·Cd）S：Ag-KI为催化剂，在单色(绿)光照下，成功地模拟了光合作用的光合磷酸化。在绿色光照下的光照度、照光时间、ADP(二磷酸腺苷) 浓度、Pi（磷酸氢二钠）浓度及催化剂量等对ATP（三磷酸腺苷）合成的影响。在合适的条件下，ADP 的浓度为1×10-1mmol/l 时的转化率可达到3.2%——5.8%。

在对美国的四大球职业联盟纪律处罚机制分析的基础上，着重对处罚中的程序公正性展开剖析，对处罚中程序不公正时的救济方式进行研究。结合国外案例和我国职业体育纪律处罚中的假球现象进行分析和比较，明确了程序公正性在纪律处罚机制中的核心地位，突出完善我国职业体育纪律处罚机制和健全我国多元体育纠纷救济机制的必要性。     

从光的衍射看光的直线传播及像质问题

光的衍射有近场衍射和远场衍射两种情形.近场衍射如小孔成像,当孔的尺寸比较大时,光线沿着直线传播,当孔小到一定程度,光线偏离了直线传播发生衍射,孔越小,衍射越显著,物体的几何像失去了清晰的轮廓,而且在边缘附近出现一系列明暗相间的条纹,从而影响了成像的质量;远场衍射如望远镜、显微镜,在物镜的像面上形成的几何像点由于衍射效应变成了一系列的衍射斑,衍射斑重叠越多,像越不清晰,严重影响了成像的质量,使得光学成像仪器的像分辨本领也有了限制.     

一部汉语言文字学研究的力作--梁光华《汉语汉字论稿》读后

梁光华先生的《汉语汉字论稿》一书 ,收录了梁先生近年来的论文四十篇 ,内容涵盖了文字学、音韵学、训诂学、语法学、词汇学、方言学、文化语言学等诸多领域。本书有以下突出的优点 :1、注意发掘新问题 ,开拓新思路 ;2、占有丰富的材料 ;3、科学的研究方法 ;4、注意科研与教学的结合。洋洋洒洒三十余万言 ,均表现出梁先生深厚的语言学功底和敏锐的视角 ,是一部语言文字学研究的力作 ,一部值得语言学者尤其是青年学者一读的好书。需要商榷的一点是轻重唇音的分化时间问题 ,梁先生主张二者分化开始于唐末 ,完成于宋初《集韵》时代 (公元 1 1世纪初 )。而笔者则认为二者的分化应开始于南朝末年至唐代初年 (公元 6世纪末至 7世纪初 ) ,完成于唐代中期。     

体育社团处罚权与司法审查权关系之研究

结合当前体育社团发展现状,运用文献资料调研、比较分析、逻辑分析等研究方法,对体育社团处罚纠纷处理机制进行专题研究。认为,体育社团拥有的内部处罚权是维护体育生存和发展必不可少的权力;为防止体育社团“滥用”或“误用”这种权力,法院有必要一定范围的司法审查权。     

论人性化借阅制度的建立

设置固定借阅期限和采取经济处罚措施是目前我国图书馆普遍采用的借阅制度,长期以来,固定借阅期限设置的科学性和合理性以及经济处罚措施的合法性和目的性一直受到读者质疑和非议,建立一种保障读者最大平等借阅权的合法合情合理的人性化的借阅制度,是图书馆服务和管理工作的迫切要求。文章从设置弹性借阅期限和改革超期处罚措施两方面对建立人性化的借阅制度进行探讨。     

Consolidation of Black-dyed Māori Textile Artefacts: Evaluating the Efficacy of Sodium Alginate

Black-dyed artefacts are found in museums worldwide, many produced using an iron-tannate compound. Deterioration of iron-tannate dyed artefacts is an international preservation issue: in New Zealand the deterioration of paru (iron-tannate) dyed Māori textiles is widespread. This article reports experimental work testing the efficacy of sodium alginate, a consolidant developed for deteriorated paru-dyed muka (fibre from harakeke; Phormium tenax). The colour stability, strength retention, and acidity of paru-dyed muka consolidated with sodium alginate (0.25, 0.5, and 1% w/v in water) was tested pre- and post-artificial light ageing. This study found that sodium alginate had no negative effect on paru-dyed muka and in some cases provided benefit. Interestingly, the colour of paru-dyed muka is substantially more stable in UV-filtered light than previously recognised. Also microfading results were in agreement with visual assessments of colour change at 1 Mlux hour exposure, providing confidence in this relatively new technique to assess colour change.     

Seeking Nettle Textiles – Utilizing a Combination of Microscopic Methods for Fibre Identification

Bast fibres have been commonly used as a textile material in Northern Europe since Neolithic times. However, the process of identifying the different species has been problematic, and many important questions related to their cultural history are still unanswered. For example, a modified Herzog test and the presence of calcium oxalate crystals have both been used in identification. In order to generate more reliable results, further research and advancement in multi-methodological methods is required. This paper introduces a combination of methods which can be used to identify and distinguish flax (Linum usitatissimum), hemp (Cannabis sativa), and stinging nettle (Urtica dioica). The research material consisted of reference fibres and 25 fibre samples obtained from 12 textiles assumed to be made of nettle. The textiles were from the Finno-Ugric and Historical Collections of The National Museum of Finland. The fibre samples were studied by observing the surface characteristics and cross sections with transmitted light microscopy, and by using a modified Herzog test with polarized light, in order to identify the distinguishable features in their morphological structures. The study showed that five out of 25 samples were cotton, 16 nettle, one flax, and one hemp. Findings from two samples were inconsistent. The results show that it is possible to distinguish common north European bast fibres from each other by using a combination of microscopic methods. Furthermore, by utilizing these combined methods, new and more reliable information could be obtained from historical ethnographic textiles, which creates new vistas for the interpretation of their cultural history.
