Urea-gypsum was prepared by solid-phase ball milling from g ypsum and urea as the material. The technological conditions were optimized by the orthogonal design;the dynamic characteristics of solid phase reaction were studied by Kissinger equation, and the urea-gypsum was characterized by XRD, FTIR, S EM and TG-DSC. The results showed that the optimum technical conditions are as follows: reaction temperature 55 ℃ , reaction time 40 min, ball-feed ratio 6:1, rotational speed 600 r min-1, and in this condition the average conversion of reaction can reach 89.38%;the relationship between the reaction rate constant KK and temperature T can be described by the formula as KK=1.5×109exp[（71.70×103）/RT];urea-gypsum prepared by solid-phase ball milling of platelike structure belongs to triclinic, and the characteristic abs orptions of IR are the stretching vibrations of N-H, C=O, C-N, S-O and deformation vibration of N-H, and the decomposition temperature of urea-gypsum is 200-220 ℃ .This paper provides a preparation for urea-gypsum with high efficiency and energy saving effective, which could improve the nitrogen use efficiency effective, reduce the agricultural nitrogen emission, and increase the crops yield, and this also open up a new technology for large-scale utilization of industrial waste such as phosphog ypsum and desulphogypsum.

＜正＞Outliers can be devastating for conventional MLE and LS based acoustic source localization *** solve this problem with less energy consumption is the focus of this paper.A contaminated Gaussian model is proposed for acoustic energy sensor readings and shown to be consistent with real-world experiment *** a novel energy-efficient robust acoustic source localization protocol（ERASLP） is introduced where each node examines its own observation by a local outlier rejection rule （LORR）.Detected outliers will not be sent to the fusion center for the final localization result *** average communication energy cost and applicability of ERASLP is analyzed and compared to typical centralized localization method and distributed optimization *** results show LORR can surpass more than a half of the outliers even with very sparsely deployed sensors and ERASLP has better tradeoff between robustness and energy consumption in most cases.

2010 Second IITA International Conference on Geoscience and Remote Sensing (IITA-GRS 2010)

作者： Yanxia Du1 Lisheng Xu1 * Yansong Fang2 Yujie Zhang2 Jilie Ding1 Hailei Liu1 and Xiaobo Deng1 1 Atmospheric Radiation & Satellite Remote Sensing Lab College of Atmospheric Sounding Chengdu University of Information Technology Chengdu china 610225 2 Shandong Meteorological Bureau Jinan china 250031

Some retrieval methods for estimating the atmospheric precipitable water （PW） were reviewed in the study. Then, an improved physically algorithm for the retrieval of PW over cloud-free land surfaces based on the split-window covariance-variance ratio technique （SWCVR） was proposed. The thermal infrared split window channels at 11 and 12 μm of the Advanced Very High Resolution Radiometer（AVHRR） instrument were used. The improved method for estimating the PW is simplified, which is based on a linear relationship between the PW and the ratio of the two split-window channel transmittances （τ12/τ11）. The new PW retrieval algorithm was tested with the comparisons from both AVHRR and radiosonde observations in some places of South china. The preliminary results show that the algorithm proposed for estimating PW is acceptable since a RMSE of 0.44 cm is obtained.
