Represented by the Xingzi Station, it was studied that the Poyang Lake water level change trend in nearly 60 years. The improved MK test and homogeneity test are used to detect trend and change points in the series of maximum and minimum water levels. Furthermore, the relationship among extreme water...

Adopting Chinese cultural perspectives, especially the symbol of Yin/Yang, we study the issue of environmental protection in a developing country such as China. First, we compare the implications of this symbol with those of a more well-known Chinese perspective, i.e., Confucianism, both of which should...

The ecological design projects of different levels were carried out at the demonstration area. From 2013 to 2015, the dynamic monitoring of the demonstration zone water quality was carried out: the background information of wetland was investigated in 2013; two wetlands with serious pollution were selected...

β-Cyclodextrin (β-CD) aqueous solution was firstly used into the removal of nitride from light oil by molecular recognition. Pyridine was chosen as a model compound and used in the denitrification experiments. And the influence factors, concentration of β-CD, time, ratio of catalyst to oil and temperature...

With the development of intensive animal husbandry, which have brought a lot of problems? The pollution is more and more serious, which has becomes a threat to the agricultural ecology and food safety. At the meanwhile, the pollution seriously affected the healthy development of the breeding industry....

There is a significant regional difference of NOX emission in China; the total emission amount of economic developed areas is larger while the economic developing regions are relative smaller. From the point of view of the changes, the total emission declining rate of developed areas is larger, which...

Antibiotics, as the most widely used medicine, have been detected in surface water, urban wastewater treatment plants, and soil. The distribution and degradation of antibiotics have received wide attention due to the "pseudo-persistence" and worldwide transmissions of resistance genes. Of all water treatment...

Compared with low-solid state, high-solid anaerobic digestion has the advantages of requiring less reactor volume, less energy input for heating and mixing and producing nutrient-richer fertilizer. Besides, it also has a higher net energy yield. It is urgently necessary to pay attention to the resource...

Combined with the Heilongjiang economic and trade development is particularly urgent requirement to build regional free trade zone border, by analogy analysis, judgment and reasoning methods, analysis of Heilongjiang Province trade development problems and cause, tax policy and the characteristics of...

The seabuckthorn plant flexible dam (The SPFD) is a new type of ecological engi-neering, which can efficaciously control soil erosion and capture sediment in the Pisha sandstone gully within Loess Plateau of China. The seabuckthorn plant can resist flow due mainly to slowing velocity, and thus reduce...

The open smart grid reference architecture (SGRA), based upon the GridWise© interoperability framework, has proposed real-time integration architecture, EDA and robust CEP as key enabling information architectural capabilities. EDA complements SOA in event based requirement analysis & design paradigm....

In the making and erection process of wall-column structural system of electrostatic precipitator casing, the imperfection will be produced inevitably and influence the stability of the column. It's necessary for numerical simulation model that the imperfection is taken into account when the numerical...

This paper discusses the condition acquisition controller's realization method based on IEC 61850 standard communication protocol. It presents a design scheme about main structure and key technologies. First, it studied the device's hardware requirements, communication environment, work flow, then designed...

With WCl6, C2H2 and H2 reaction system and Ar work gas, WC nanocrystallites were prepared by plasma chemical vapor deposition(PCVD). The properties of WCl6 and WC particles including chemical composition, morphology, size and structure of crystal phase were characterized by Transmission Electron Microscopy...

As a new energy-saving conductor, ACCC conductor, which has the advantages of low weight, high conductivity, can double the ampacity of conventional conductors. However due to the differences between ACCC conductor and conventional conductors, present current-temperature model cannot be directly applied...

This paper establishes hydrodynamic models for the focused river section by Delft3D model, simulates the oil spill trajectory and the fates by Oilmap model, and establishes a combined application method of hydrodynamic and oil spill simulation model available for the Yangtze River and other inland waters....

In order to research the distribution of residual chlorine of LNG drainage in the ocean, further to formulate reasonable wastewater marine disposal scheme and provide scientific support to the protection of environment. According to the tidal current characteristics of the drainage and receiving waters...

As we all know, during the Neogene the uplift of the Tibetan Plateau caused profound changes in the regional landforms and climate, and influenced the development of the Asian monsoons. The Neogene global cooling is a crucial event of geology history when the aridity in the Asian interior enhanced and...
