With the sustaining economic development in China, the timely, accurate and objective agricultural production information service has been highly demanded by the central and provincial governments. China Agricultural Remote Sensing Monitoring System (CHARMS) is an operational agricultural monitoring system in the Ministry of Agriculture of China to meet this demand.
This paper reports a scale treatment on purified terephthalic acid (PTA) productive wastewater in a 50L column form reactor by ultrasound enhanced ozonation. The degradation effects of three kinds of productive wastewater including inlet and outlet water from treatment works as well as accident wastewater are investigated. The results show that the ultrasound enhanced ozonation is an efficient way...
Regional R&D(research and development) activities play a kind of important role on the enhancement of regional economic competition. By analyzing R&D funds inputs, staff inputs and outputs status related to R&D activities, an improved DEA model is used to calculate input and output efficiency on R&D activities from the year 2003 to 2008 in Hebei province. Compared with the both cities...
This paper demonstrates the Ruddick's algorithm to utilize atmospheric correction with the hyper-spectral imagery over Chinese turbid lake water obtained by China first hyperspectral imager (HSI) onboard HJ-1A. The paper studies on the sensor characteristics and analyzes the optical properties of turbid lake water in Taihu Lake. Based on consideration about real circumstances, the paper recalibrates...
Numerical analysis, on-site measurements, and laboratory experiments are used in this paper to analyze and solve the flashover problems of 330 kV AC high altitudes transmission line middle phase glass suspension insulator strings. A sub-model approach based on a finite element method (FEM) applied in calculating the potential and electric field distribution along the insulator strings under clean...
