Based on the principle of fuzzy matter-element analysis, the concept of information entropy is introduced to establish a fuzzy matter-element evaluation method. This method is utilized to comprehensively evaluate the degree of debris flow. The classifications of debris flow are regarded as the objects of matter-element and their indexes for evaluation as well as the corresponding fuzzy values are used to construct the composite fuzzy matter-elements. By calculating the relevancy the comprehensive evaluation of debris flow can be carried out. This model is applied to analyze the degree of debris flow in the practical application. The application shows that the model is effective and practical.

Cashmere shrink-proofing effect by enzyme can't achieve ideal shrink-proof effect, so hydrogen peroxide + Savinase protease combined treatment was selected to treat cashmere fiber. In this paper, the included angle cosine method was used to determine the empowerment weight, and used the fuzzy matter-element analysis to fuzzy comprehensive evaluation of the experimental index, the optimum conditions is: hydrogen peroxide pretreatment temperature 35 °C, time 45min, H2O2 40ml / L, pH 9, pyrophosphate 5g / L, the temperature of enzyme treatment 35 °C, time 25min, concentration 40ml / L, pH 9. After cashmere fibers were treated in hydrogen peroxide and Savinase protease combined treatment, cashmere’s Shrink-proofing is well.

Previously, factors affecting freeway network safety under all operational circumstances have been divided hierarchically. Consequently, evaluation indicators for highway safety have been established on the basis of specification and twin statistic data. We present a novel multi-objective comprehensive evaluation method for the safe operation of segments of a highway network, together with the calculation formula, based on matter element analysis. In addition, the method is evaluated using an example.

The aim of this study was to obtain the method of the green design and modular design that oriented construction machinery products. A variety of modern design tools such as the finite element analysis software package and optimize design package and a two-factor evaluation fuzzy modelare used to analyze and Evaluation the green degree and the module degree of the construction machinery. Some modern mathematical tools such as AHP and fuzzy comprehensive evaluation method are used to calculate and evaluate the green degree and the module degree in construction machinery design. The proposed design method can meet the requirements of the green degree and the module degree of the construction machinery.
