In order to solve the universal uncertainty in ecological environment evaluation of coal mining area, the cloud model is proposed. Theory of cloud model is introduced; a new method of coal mineral area ecological environment evaluation based on cloud model is presented ...

Natural gas has been one of the most important kinds of vehicle fuel since the discovery of abundant shale gas storage. Operating costs of diesel engine can be reduced by replacing diesel with diesel-CNG dual fuel. The present contribution is mainly about the electronic...

The major indoor air pollution-formaldehyde has been a serious threat to our lives to our lives, and accordingly the formaldehyde degradation has turned into a concerned issue of public. This paper has based on a number of degradation methods and combined the adsorption...

Today, high technology is transforming traditional industry. The science, suitable measuring technique and data application method are the basis of large-scale manufacture realizing, which not only meet individual consumer demand, but also are meaningful to raise the ec...

The SO2 concentration can be figured out through measuring the light intensity attenuation. But the scattering and absorption of the multidispersion soot particles can attenuate the light intensity, so the visible measurement light intensity attenuation is larger and th...

In order to realize the rapid and precise 3D profile measurement of workpieces with tiny-dimension characteristics, optical double-triangulation is studied. The measuring accuracy is affected by many factors such as system structure, surface characteristic and the circu...

In the specialized literature the cost of the machining process has been analyzed using a number of approaches and varying degrees of simplification to determine the optimum tool life and the tool speed. The accuracy of prediction is dependent on the degree of sophistic...

The properties of nanostructured aluminum (Al) doped zinc oxide (ZnO) thin film for thin film transistors (TFT) are presented. This research has been focused on optical and structural properties of Al doped ZnO thin film. The influence of Al doping concentration at 0~5 ...

The surface charge and average size of ZnO was studied with a function of pH and time. The interactions between ZnO and Suwannee River humic acid (SRHA) were further investigated under a range of environmentally relevant conditions with the pHPZC as a point of reference...

There was carbon dioxide (CO2), hydrogen sulfide (H2S) and other corrosive media in underground gas storage. As injection-production running, the injection and production string suffered corrosion. The wall of string might be thinner and be perforated. The well safety w...
