However, the 3 groups from medium A exhibited the highest microbial diversity and best decolorization results with 99.53% and 97.42% color removal rate of Reactive Red M-3BE and Acid Red. From them, 16 strains of fungi were isolated and primarily identified as Saprolegniaceae, Eurotiaceae, Erysiphaceae and Physodermataceae . Fungi groups from medium B and D exhibited a bit lower color removal rate of various dyes and only 3 and 2 isolates primarily classified as Saccharomycetaceae and Eurotiaceae were obtained from them. Fungi cultures in medium A and B could produce lignin peroxidase, and those in medium D could be detected higher activity of laccase. All the fungal cultures exhibited very weak activity of manganese dependant peroxidase.

Regardless to the research development or industrial application, nano metal powders are extensively discussed. Within these powders, the flammable and explosible nano aluminum, titanium and iron powders produce a great amount production and apply widely. Meanwhile, the surface/volume ratio of powders is increased significantly under nano scale, in which to enhance the ignition opportunity. Thus, the dust explosion hazard risk of nano powders could remarkable rise. In addition, the comparison of explosion phenomenon, test methods and quantification parameters between nano and micro scale is necessary to deeply investigate further. So that this project operates the explosion characteristic experiments to measure and determine such the maximum explosion pressure, minimum explosion concentration and explosion characteristic Kst value on above mentioned three nano metal powders. Expectantly, to provide the appropriate recommendations of safety prevention for nano dust explosion based on the experimental results.
奈米金属粉末无论是研究发展或是工业界应用,目前皆是广泛讨论研究之材料,其中,奈米铝粉、奈米钛粉以及奈米铁粉等可燃、爆性粉末,均有高额产量及大量应用领域,与此同时,在粉末粒径进入奈米尺度的情况下,粉尘比表面积大幅提升,增加此三种粉尘可被点燃的机会,因此,潜在的粉尘爆炸危害风险将广幅增加,另外,微米尺度粉尘爆炸的现象、测试方法以及量化参数是否具有相同的实验尺度基点,也需要深入探讨,故本次计画针对上述三种奈米金属粉末,进行三种不同粒径的爆炸特性参数实验,如最大爆炸压力、最低爆炸浓度以及爆炸特性参数Kst值之量测与计算,期能量化其粉尘爆炸特性,并据此提出适当的安全防护建议。

Based on them, this paper proposes evaluation indexof fund performance from the aspect of finance, investor and interiormanagement. Considering the limitation of data envelopment analysis approach usedto evaluate fund performance, such as conventional DEA models can not considerinputs and outputs of evaluation units simultaneously, and an input-oriented DEAmodel and output-oriented DEA model often produce different evaluation results,this paper proposes a general form of DEA model which is input- andoutput-oriented by using multi-objective optimization and fuzzy set theory. Sincethe general form of DEA model can be transformed into a conventional input oroutput oriented DEA model by using special membership functions, it can beseemed as a nature extense of conventional DEA models, and a conventionalmodel can be regarded as a special case of DEA mdoel with general form.
针对现有基金绩效评价方法中较具优越性的数据包络分析方法的不足,如传统DEA模型不能同时综合考虑评价单元的输入和输出,以及分别采用面向输入和面向输出DEA模型评价基金绩效时,常常出现不一致的评价结果等,本文以多目标优化与模糊集合理论为工具,提出了一种能够同时面向输入和输出的DEA一般形式模型,并通过选择一些特殊的模糊集合隶属函数,使得这种DEA一般形式模型成为传统DEA模型的自然推广,而传统DEA模型是该模型的特殊形式。
