Abstract. The relative contributions of C3 and C4 plants to vegetation at a given locality may be estimated by means δ13C soil organic matter. This approach holds great potential for paleoecological reconstruction using paleosols. However, two main uncertainties exist, which limits the accuracy this application. One is δ13C-enrichment as plant carbon becomes incorporated into other due environmental influences on plants. Two types data were collected analyzed with an objective narrowing...
The IPCC assume a linear relationship between nitrogen (N) application rate and nitrous oxide (N2O) emissions in inventory reporting, however, growing number of studies show nonlinear under specific soil-climatic conditions. In the North China plain, global hotspot N2O emissions, covering land as large Germany, correlation N remains unclear. We have therefore specifically investigated response to applications by conducting field experiments with five rates, high-frequency measurements across...
In order to achieve real-time prediction of the battery internal temperature via external measured, a method for predicting ternary polymer lithium-ion pack based on convolutional neural networks (CNN) and virtual thermal sensor (VTS) was proposed in this paper. A 128-channel thermometer used measure (64 uniformly distributed points) during seven discharge cycles total 81 376 sets data. The measured as input CNN predicted output CNN. compared with linear regression (LR) verify difference...
Abstract Many studies have documented that the δ 13 C values of plants increase with altitude both on a global scale and locally in humid climates, while semi‐arid areas opposite trend has been found. The study reported herein was conducted mountainous area China characterized by temperate semi‐humid climate. 3 species do not exhibit consistent variation along an altitudinal gradient observations suggest pattern increasing cannot be generalized. In area, addition to environmental factors...

We monitored soil respiration (Rs), temperature (T) and volumetric water content (VWC%) over four years in one typical conventional alternative cropping systems to understand Rs different with their respective management practices environmental conditions. The control was double-cropping system (winter wheat summer maize year - Con.W/M). Four were designed optimum N management, i.e. optimized winter (Opt.W/M), three harvests every two (first year, or soybean; second fallow then spring W/M-M...
The paper provides valve cooling system operational performance in Guangzhou converter station of Tian-Guang HVDC Interconnection. It was envisaged that such information could be useful the planning and construction new projects. also benefit to those concerned with operation maintenance existing schemes. This highlights some important parameters for period from 26 June 2001 31 2011, including trips forced outages caused by system.
In recent years, with the vigorous construction of ultra-high voltage grid, line operating level has become higher and higher. order to ensure safe operation transmission line, insulator string a length several tens meters, traditional manual testing been unable meet requirements. With continuous maturity wireless communication technology, electromagnetic compatibility sensor technology other comprehensive technologies, it is necessary develop an detection robot replace artificial work on...
With the rapid development of power grid construction, The Power is becoming more and expansion; reliability equipment operation important precondition for safe stable grid. insulator an component primary So it to research high efficient, accurate detector insulativity insulator. This paper based on current problems detection, An online detection device intelligent robot studied. By installing onto robot, will be able detect online. There no need artificially screening tests reduce...
Detecting the low value insulator in string on-line is of great significance to safe and stable operation power system. It one most important technical problems construction HVDC transmission project our country. At present, there are many researches on HV AC strings both at home abroad, but only mode recently used, few this kind lines. In view new problem, after a number research design, invented DC for high voltage zero line detection device, device can effectively detect insulators,...
