Conventional methane gas sensors based on catalytic combustion have the drawbacks of high working temperature, low thermal stability and small measurement range. To improve their performance, cerium, which possesses high oxygen storage and release ability, was introduced via nanotechnology to prepare Ce-contained nanostructure elements. Three kinds of(More)
In order to achieve precisely two-dimensional spatial distribution reconstruction of smoke plume, passive MAX-DOAS tomography is established, the measurement of the spatial distribution of the exhaust plume is implemented by more passive multi-axis differential absorption spectrum system. First, the multi-axis differential absorption spectrum system and its(More)
In this paper, conventional CMF secondary instrument is improved by embedding modified BPNN algorithm for real-time and accurate monitoring water inrush in mine. The data of frequency, temperature and phase difference determined by CMF is applied to train network, as a result, phase frequency property of flow signal may be analyzed precisely for measuring(More)
This paper introduces a new way to analyze mixtures of inflammable gases with a single catalytic sensor. The analysis technology was based on a new finding that an electric field on the catalytic sensor can change the output sensitivity of the sensor. The analysis of mixed inflammable gases results from processing the output signals obtained by adjusting(More)
Abstract—In order to improve the accuracy of prediction of gas accuracy problem. Actually, there are no sufficient academic emission, a novel nonlinear combined prediction method using backgrounds for this method. It’s a take-it-for-granted support vector machines(SVM) was introduced. SVM, which was behavior. based on the rule of structural error(More)
In this paper a new forecast approach of coal mine dimensional and real-time, but it can also further analyze the water inrush based on microseismic monitoring technique was rupture scale and properties according to the source. Therefore, introduced. Coal rock microseismic signal was characterized by a novel means is provided to study the coal floor rupture(More)
