中国省域旅游企业综合实力分析--兼析如何提升安徽省旅游企业综合实力

从旅游企业规模和企业效益两方面入手,构建出中国省域旅游企业综合实力分析的2类10项指标体系,利用具有全国可比性的权威性数据,借助统计学分析软件SPSS,采用因子分析法对中国各省域旅游企业综合实力进行了详细测度和具体分析.最后针对安徽省旅游企业综合实力落后的问题,提出了相应对策.     

聚合硅酸硫酸铝对印染废水的预处理实验研究

本文采用硅酸钠、硫酸和硫酸铝为原料，制备出无机高分子絮凝剂聚合硅酸硫酸铝，探讨了聚合硅酸硫酸铝对广东某毛纺企业印染废水的应用性能。结果表明，聚合硅酸硫酸铝对COD和色度的去除率优于硫酸亚铁，COD和色度去除率分别可达31．8％和84％，减轻了后续生化系统的压力。     

电解制备高铁酸盐及其处理苯胺废水的研究

采用双阴极室隔膜电解槽，以平板灰口铸铁为阳极，电解法制备水处理剂高铁酸盐，电解150min，得到浓度为27．1mmoi／L的FeO2^2-。以其氧化降解模拟废水中的苯胺，在pH为5，高铁酸盐相对苯胺过量的条件下，苯胺的去除率接近100％，COD去除率达80％以上。高铁酸盐与苯胺的反应符合一级动力学规律。紫外一可见光谱、高效液相色谱的分析表明，苯胺降解过程中有一系列中间产物生成，最终被矿化成小分子无机物。     

Photosensitized Inactivation of Cyst Forms of the Freshwater Amoeba <Emphasis Type="Italic">Vahlkampfia hartmanni</Emphasis> by Aluminium (III) Phthalocyanine Tetrasulfonate

Summary In this work we attained a successful cysticidal effect against Vahlkampfia hartmanni cysts using mild to moderate experimental conditions, regarding light energy delivered and concentrations of aluminium phthalocyanine tetrasulfonate (AlPCS4). The dark and phototoxic activity of AlPCS4 towards the cyst forms of Vahlkampfia hartmanni, a freshwater amoeba previously isolated from keratitic patients, were tested. The photosensitized deactivation of the cyst form of this amoeba depends mainly on the concentration of AlPCS4 and the light fluence rate as well as the total fluence delivered during the irradiation process. Upon irradiation of the cyst suspension at 100 mW/cm² for 10 minutes in the presence of 3 μ M AlPCS4, a complete photodamaging effect on the cysts was induced. The photodamaging effect on Vahlkampfia cysts induces a state of inability of the cysts to excyst, vacuolation of the inner contents as well as a significant damage of the outer cyst wall upon microscopic examination.     

OEM在生物制药企业GMP认证中的抗风险作用

有关数据表明,OEM制造方式正大踏步进入中国,尤其盛行在IT业、服装业和机电业。OEM是在国际市场十分流行并行之有效的生产方式,但在生物制药企业中还不多见。作者通过对生物制药企业面临GMP认证风险分析及OEM应用的好处得出结论,采取OEM方式是生物制药企业GMP认证风险的有效克星。     

发展乡镇企业与关停“15小”

部分地方对关停“１５小”行动不力，主要是由于当地负责人和企业法人只注重眼前的经济利益，无视对生态环境的破坏。应狠抓对乡镇各级干部的环保法规宣传，严格项目审批手续和“三同时”制度，坚决关停“１５小”企业。     

Accumulation of elements by edible mushroom species II. A comparison of aluminium,barium and nutritional element contents

The aim of the study was to compare accumulation efficiency of Al, Ba and nutritional elements (Ca, Fe, K, Mg, Mn, Na) exhibited by six edible mushrooms collected in particular regions of Poland during the last 20 years. The studied mushroom species were Boletus edulis, Cantharellus cibarius, Lactarius deliciosus, Leccinum aurantiacum, Suillus luteus and Xerocomus badius. The highest and the lowest concentrations of the elements in tested mushroom species were 11 – 410, 34 – 337, 16785 – 34600, 140 – 607, 12 – 75 and 16 – 143 mg kg^?1d.m., respectively. The highest average concentrations of Al, Mg and Mn were observed in Suillus luteus fruiting bodies, while for Ba, Ca, K and Na it was in Lactarius deliciosus. BCF >1 was found for K and Mg in all tested mushroom species and additionally for the highest Ca and Na concentrations of all tested mushroom species except for C. cibarius and S. luteus, respectively. For the other tested elements (Al, Ba, Fe and Mn) BCF values < 1 were recorded.

基于模糊数学的石化企业安全状况评估系统

针对石化企业安全信息存在模糊性和随机性的特点,提出了一个多因素多指标石化企业安全状况模糊综合评价算法,基于这种算法,设计了一个石化企业安全状况评估系统,以安全管理、工艺运行管理、设备运行管理、清洁生产、安全教育和人员素质等因素为系统的输入,运用模糊逻辑理论,结合专家评分,定量计算出石化企业的安全等级情况。系统充分考虑了多个安全因素对安全状况的影响,融合了主观判断和客观计算,解决了石化企业安全评价中多因素多指标带来的烦琐评价过程和复杂运算的问题,为石油化工企业的安全管理提供相关理论依据和实践支持。实际应用表明,其结果与实际情况较为符合,该方法可以较好的提高石化企业安全现状综合评价的客观性和准确性。
