BPBC处理苯酚废水的实验研究结果表明，苯酚的降解速率与酚浓度呈一级反应关系，即随着实际电解时间的增加苯酚降解速率逐渐减小；随着槽电压的增大，苯酚的去除率也随之增大，但是槽电压超过10V后，苯酚去除率增加趋势减缓；在碱性条件下，pH值的变化对苯酚的去除率有一定的影响，随着pH值的增大，去除率逐渐的降低；空床流速过大时，苯酚去除率有一定的下降；投加电解质后，苯酚的去除率增加，而就投加NaCl和NaNO_3的情况下，投加等摩尔浓度的NaCl和NaNO_3，投加NaCl的效果要优于投加NaNO_3的效果；提高废水中的溶解氧有利于苯酚的去除。

There are experimental results as follows:(1) Eriophorum comosum Nees shows strong cold resistance in plasmalemma permeability research. The lethal temperature of Eriophorum comosum Nees is the lowest LT_(50 in comparison with another two plants and is lower than -11.5℃ in August 2005 and December 2005; Soluble protein content of each plant is rising before or after cold hardiness. By SDS-PAGE, Protein band is analysed. Band quantity of Eriophorum comosum Nees is the most and its band color is darkest.(2) Soluble sugar content of three plants after cold hardiness are higher than before cold hardiness, moreover soluble sugar content after cold hardiness shows a decline and there is a narrow range in Eriophorum comosum Nees; Free Proline accumulation is changed by cold stress, and cold resistance is relative to free Proline accumulation; chlorophyll content of both three plants, including chlorophyll a, chlorophyll b and chlorophyll a/b, show a decline tendency along with the descent of temperature. Cynodon dactylon is highly sensitive to cold stress.(3) The soil POD and urease activities' absolute value of Erioophorum comosum Nees and Pogonatherum panideumHack were more than that of Cynodon dactylon before or after low temperature stress, especially POD activities.

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。
