Optimization methods such as the optimum excess air coefficient adjustment test, the combination of unit load and burner, secondary air distribution mode have been proposed. Actual operating...

To make full use of rainwater resources, and to reduce the environmental stress brought about by rainwater drainage, rainwater sampled in a residential area in Yancheng City, Jiangsu Province was treated by four processes: rainwater sand filtration disinfection discharge; rainwater coagulation sedimentation...

Secondary pollution, caused by the stench gas from the sewage treatment plant (station), has become one of the key environmental petition complaint. In this paper, the impact of malodorous gases Harbin Brewery (Shenyang) Co., sewage treatment station for residents, set design and construction of washing...

Visualization study of two-phase flow in serpentine anode flow field of a liquid-feed direct methanol fuel cell (DMFC) was performed, and also the internal temperature characteristics of the flow in the DMFC have been studied in order to investigate the effect of important operating parameters. The results...

Late Proterozoic, Luliang movement made vast areas of North China into the sector development period. Early Cambrian, North China block sank as a whole, depositing a 500 to 1400 meters stable carbonate sedimentary rocks. Jurassic - Cretaceous, Tangxi fracture and Tangdong fracture started to move, Tangyin...

The carboniferous igneous rock in the west Junggar Basin mainly composed of tuff, andesite, basalt and volcanic breccia is very hard to exactly distinguish via geological logging. Based on logging data coupled with cores, logging cross plot, imaging logging and fisher discriminant was used to identify...

It builds on research by Dollhopf and other scientists in the Land Resources and Environmental Services Department and the Plant Sciences and...

Hyperspectral remote sensing is a frontier field of remote sensing due to its advantage of object recognition based on spectral characteristics. This study carried out geological application of HySpex ground-based hyperspectral data at scales of both alteration belt in the Asiha gold district of Qinghai...

Distributed generator is often associated with the existing distribution network system, the study of the impact of the distributed generation on original distribution network system is very important for the development of the smart grid. The study on the voltage can contribute to the safety, reliability...

Life Cycle Cost Management is a quantitative analysis method. During the grid operation, load growth causing reduced reliability phenomenon such as some lines overloads, electric power enterprises to re-plan and transformate transmission line to ensure the reliability. In this context, in order to reduce...

Aim at the reservoirs condition of high porosity, high permeability, high viscosity of crude oil in the offshore oilfield, this paper used two-dimensional heterogeneous physical model to conduct laboratory displacement experiments which contain water flooding, polymer flooding and binary combination...

Polymer flooding has a large-scale promotion in Daqing oilfield, this paper prepared two-dimensional heterogeneous model according to the typical reservoir in Daqing oilfield and did the experiments of water flooding and polymer flooding with the method of three tubes parallel, monitored the oil saturation...

Leucaena leucocephala has been widely used in the ecological restoration and protection of engineering slopes in southwest hydropower projects. It is one of the key issues in slope ecological restoration that how to determine seeding age for transplantation. The erosion resistance, scour resistance,...

For the development of oil and gas field, the effective viscosity determination of the viscoelastic fluid is always the problem of chemical flooding and there are technical problems to verify difficultly. The common methods include bulk phase viscosity method, the rheological curve method, and the drag...

In view of the formation characteristics as the high viscosity and the high permeability of offshore heavy oil reservoir, simulation of artificial core was developed. The indoor physical simulation experiments under the offshore oil field reservoir conditions were conducted. The effective viscosity of...

The sliding distance is the most critical risk factors in landslide disasters, and many factors affects landslide sliding distance. In order to investigate the influence of various factors on the landslide sliding distance, take the loess landslides on south of Jing he River in Xi'an as the study area,...

Harmonic voltage of the concern bus in the power grid is the combinations of voltage contributions of each harmonic source. When the main harmonic sources are known to the system, how to distinguish the responsibility of these harmonic sources has important significance. This paper firstly established...

Fast Fourier transform(FFT) is an important tool for harmonic analysis in power systems and a method of FFT analysis of the signal is very important for power systems. For finding and forming a basic way to FFT analysis of feeder current, the paper embarks from the principle of Fourier transform and...

This paper is with the purpose of catastrophe point identification and comparison between wavelet analysis and Fourier analysis on their effects of filtering, and apply it into the analysis of traction substation feeder current. First, we assess the differences between wavelet analysis and Fourier analysis...

Due to the current explosion of the network traffic generated by content production and dissemination applications like popular video, Content-Centric Networking (CCN) has been the topic of recent research. In-network caching for CCN is expected to achieve an adaptive content delivery in the network...
