UV induced degradation of crude oil in polluted water based on analysis of environmental materials Hui Liua,*,Bing Sunb, Zhiyu Yanc, Xiaoyu Tiand College of Environmental Science and Engineering, Dalian Maritime University, Linghai Road 1, Dalian, 116026, China.
Analysis of environmental materials is very important for the environmental assessment, especially for the crude oil-contaminated water.
Introduction Analysis of environmental materials, which include air, water, soil or any biological materials, has been performed to achieve the monitoring of the environment, so that man can assess a better environmental condition.
The results showed that all the environmental materials analyzed decreased during the UV irradiation.

The AHP-Fuzzy as one of system analysis methods is very good at deal with the insufficiencies atonement weight sum total scoring rank order method, had been used widely in many domains of systems engineering.
Standard layer includes five weighting factor, pollutant emission and material consumptions, energy consumption and cleaner production potential and process cooperation degree.
Hierarchy total taxis Applying to all kinds of audit key factors has shown below: 1.
AHP-Fuzzy method, as a kind of system engineering analysis method have a wide range of applications in many fields, such as appointment and removal of the cadre and personnel, vendor selection, product selection, performance evaluation, plan optimization, etc.

There are many factors that affect listening, among which materials play a key role in facilitating listening comprehension.
Some materials are not authentic but recorded in the form of a series of testing items.
New model of listening training accordingly attaches more importance to its materials.
Listening materials should be adjusted and updated frequently on the basis of learnes’ needs, which is largely because of the fact that materials are “the tangible manifestation of the curriculum in action ” [2].
A full –scale questionnaire including 18 questions was conducted among 80 non-English majors , who are mainly freshmen and sophoremores from eight different majors at Wuhan Polytechnic University , such as engineering , information technology, art design ,humanities and so on.

Secondly, according to the actual processes of the maintenance, we determine the key statuses of the digital prototype and build up the key frames.
But its’ visual effect is poor because of digital models do not have material, textures, and other details without CG processing.
After adding details such as material and materials, the models are imported into Ngrain software.
Actual verification shows that materials and textures of original models can be retained better in this method.

This work provides a foundational analytical framework for studying contact problems in viscoelastic materials.
Nonlinear electro-viscoelastic materials, characterized by their combined mechanical, electrical, and time-dependent viscoelastic properties, play a crucial role in various advanced engineering and technological applications [14, 7].
A key aspect of the model is the representation of material damage through a damage variable, denoted by α.
The results presented here offer valuable insights for advanced engineering applications, such as the design of electro-viscoelastic systems and wearable health sensors.

The method of surveying data processing about engineering distortion was investigated.
Introduction In general, the engineering geometric distortion is measured by surveying.
Usually surveying data of engineering distortion is discrete.
It is to say that entropy concealing in surveying data can help us reveal the relation between error and distortion of engineering surveying data.
