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。

Treatment under mild condition with solvent of lower polarity was in favor of keeping the molecular structure and properties such as water-solubility, gelatination, etc. Acetyl groups were partially eliminated when purified by Pb2 method, leading to increased crystallinity and glass temperature, which resulted in losts of water-solubility and gelatinability. Owing to the slight oxidative degradation with H2O2 method, the changes of chain size and some functional groups of KGM molecule led to decrease of viscosity and excessive swelling rate.

采用温和条件及低极性溶剂有利於保持KGM本身的分子结构以及水溶性、凝胶性等性能；而Pb2法由於部分脱去了KGM的乙酰基，导致结晶度变大，玻璃化温度升高，最终失去水溶性和凝胶性；H2O2法则由於对KGM造成了氧化降解，也改变了分子链的大小以及部分基团，从而导致粘度降低以及溶涨速度较快。

In this way, the credibility of evidence is very important, so the second research question is how the credibility of evidence is achieved by using these main appraisal resources, that is, how the authenticity, relevance and legality of evidence are better proved through the employment of these main appraisal resources.with regard to the third research question, jef verschueren's adaptation theory, especially the three worlds, that is, physical world, mental world and social world, is used to explain why these main appraisal resources are used to better achieve the goals of courtroom participants.it is hoped that this thesis, according to the analysis of ten civil courtroom trial discourses, is going to shed some light on the study of courtroom trials from the perspective of linguistics, enrich the scope of application of appraisal theory and enlighten some scholars in the legal field.

由此可见，证据的可信度在民事法庭审判中是十分重要的，因此，本文的第二个研究问题就是法庭审判的各方是如何通过主要评价资源的应用来更好的说明己方证据的可信度以及对方证据的不可信的，即庭审中的各方是怎样通过使用主要的评价资源来达到证明己方证据的可信度的。对于第三个研究问题，该论文使用jef verschueren's的顺应理论，特别是三个世界(物理世界、心理世界以及社交世界)的理论来解释为什么要使用这些主要的评价资源。该论文的意义在于通过对十个民事法庭审判语篇的研究来给从语言学的角度研究法庭审判提供一定的思考，扩大评价理论应用的范围以及给法律界的学者们一些启发。

Through contrasting and analysing the experimental results from these methods, the paper summarizes the regularity of collapsing deformation and the shear strength index changes with the degree of saturation and stress, describes the collapsing deformation properties and strength characters of the collapsible loess in the course of moistening and drying, and describes the influence to collapsing deformation of loess from different paths of stress. Through performing monaxial compression test on samples with different paths of inundation and direction of press, proves the conclusion that collapse has nothing to do with the path of inundation and the collapsible loess has the prominent anisotropy characters.
