THE concentrations of iodine in humic acid-high underground water are not low, but the IDD disease isprevailing in some areas and no such disease is reported in some other areas. In order to explore the causes of disease and the factors affecting the concentrations of I in underground water, the author collected51.water samples from the Amengbayingmaodao Farm, Langshan Town, Linghe City of Bameng, ShibaTown of Wuyuan County, Qingshan Town of Wulatiehou Prefecture, and Zhijiliang Village in the suburbsof Hohhot City in the central and western part of Inner Mongolia for investigation. The analytical resultsshow that the water samples were relatively alkaline （pH=7.91.on average）. The average concentrationsof cations vary in the order of Na+>Ca2.> Mg2.>K+ while those of anions follow the decreasing

WE expanded Decomposition-Denitrification （DNDC）modeling study to systematically assess the potential effect of farming practice on N2./sub>O emission by choosing a corn-rape rotation and a soybean-winterwheat rotation field in Guizhou Province, westsouthern china, asN2./sub>O emission from subtropical agricultural soil study plots. These sensitivity studies address questions relevant to issue of how change in fanning practice might be used to mitigate emissions. Manure additions had the most pronounced impact on N2./sub>O emissions of farming practice simulatedand the influence of manure addition was nonlinear （fig. 1.. This result is consistent with previous studies for an Iowa corn field. The addition of manure remarkably elevates the level of organic carbon, enhances soil nitrogen mineralization, and increases the efficiency of N2./sub>O production. Simulated results alsoshowed that the influence of manure additions on N2./sub>O emission from soybean-winter wheat field had

Based on the laboratory calibration before launch of CBERS-02.IRMSS thermal infrared channel, the onboard blackbody calibration, the radiometric cross- calibration against TERRA MODIS corresponding channel and the in-flight field calibration at Lake Qinghai: water surface radiometric calibration test site of china on Aug. 1., 2.04 are carried out in this research. When making onboard blackbody calibration of CBERS-02.IRMSS, it is necessary to understand inside structures and light path in IRMSS camera and receive and process calibration blackbody signals at normal and high temperatures. Onboard blackbody calibration results of each detector are very important to relative radiometric calibration of images processing and absolute radiometric calibration of each detector. In-flight field calibration mainly contains field experiments, obtaining synchronous images, spectrum marching and MODTRAN radiative transmi- ssion computation. Radiometric cross-calibration of CBERS-02.IRMSS thermal band against TERRA MODIS selected 6 times synchronous images of two sensors passing through Lake Qinghai and Lake Taihu from August to December, 2.04 to compute the cross calibration data. Combining the in-flight field calibration and radiometric cross calibration data, the absolute radiometric calibration coefficients are calculated by the linear regression method. This new calibration model can obviously control the radiometric calibration uncertainties aroused by the single point method used in the in-flight calibration of CBERS-02.IRMSS, this kind of sensors cannot receive the cosmic background radiation. In this research, the radiometric calibration coefficients obtained through the linear regression model are 8.53 (gain, unit: DN/W m?2.r?1.m?1. and 44.92.(offset, unit: DN).

Dear Editor, GA and ABA antagonize each other in controlling seed germination, but the molecular mechanism is not fully understood. The F-box proteins act as the most important SCF （SKP1. cullin/CDC53, F-box protein） complex subunit of the ubiquitin （Ub）- 2.S proteasome system, mediate diverse physiological processes ranging from hormonal signaling cascades to environmental stress responses （Santner and Estelle, 2.1.）. We previously demonstrated that FOAl （F-box overexpressed/oppressed ABA signaling） is an ABA signaling-related gene,
