Investigation on Lunar polar area is almost every lunar mission’s primary objective in recent years. The rationale behind it is that illumination and ice resources in this area can be potentially very helpful for constructing lunar human base. In this paper, we analyze microwave radiometric characteristics of the Moon by using the newly acquired Chang’E-1 Lunar Microwave Sounder (CELMS) data. Microwave brightness temperature at Lunar South Pole (LSP) is distributed regularly with a style of "ring-in-ring", decreasing from equator to pole. Regolith temperature gradient is bigger at lunar equator than at polar area. Brightness temperature diurnal difference decreases with observation frequency. Microwave brightness temperature distribution maps at LSP and Lunar North Pole (LNP) have been made based on the analysis. It is found that microwave brightness temperature becomes to synchronize with elevation beyond -85° latitude. This phenomenon is related to lightening condition and indicates temperature distribution at LSP. The brightness temperature anomaly cold points are potentially cold trap areas for water or ice while hot points imply plenty of illumination resources there.

CE-1 Lunar Microwave Sounder (CELMS) is the first passive microwave radiometer in the world to sound the surface of the Moon in the lunar orbit at altitude of 200 km. The scientific objective of CELMS is to obtain global brightness temperature (TB) of the Moon, to retrieve information on lunar regolith, and to evaluate the distribution of helium-3 on the Moon implanted by solar wind. Before launch of CELMS, a series of experiments were carried out in laboratories to test the performances of the systems, and to calibrate the responses between the input of TB and the output of voltage from the receivers. However, the thermal condition exposed to CELMS is more complicated in lunar orbit than on the Earth, which makes the temperatures of different parts of CELMS wave vary greatly, and the cosmic background is not very clean due to the pointing of cold space antenna to the direction of the satellite running, which brings uncertainties into data-processing of CELMS when the temperature of cold space is used as a calibrator. Furthermore, the lack of knowledge on the lunar ingredients and compositions, distributions of physical temperatures, and properties on lunar microwave radiation leads to difficulties in validating the measurements and retrievals of CELMS. By analyzing the results of ground experiments and the measurements of CELMS in-orbit, along with our knowledge of the properties of lunar surface, here we give algorithms on calibration and antenna pattern correction (APC) of CELMS. We also describe in detail the principle of microwave transfer among the elements of CELMS, and discuss the method on testing calibration parameters of the system. In addition, the theory and model on correction antenna pattern of CELMS are developed by comparing antenna temperatures by CELMS with those simulated by microwave radiative transfer models. The global distribution of TB is given and the features of TB are analyzed. Our results show rich information included in TB on the prope

为揭示火山熔岩石板田土壤环境对提升寒地水稻稻米品质的机制,选取黑龙江省牡丹江响水火山玄武岩天然石板地水稻田(T_(1))和临近5.2 km的非石板地水稻田(T_(2)),采集土壤样本测定理化性状和元素含量等指标,并测定水稻品种灌浆结实期叶片光合参数、植株各部位N、P、K养分吸收、籽粒碳氮代谢关键酶活性变化及稻米品质指标,分析各品质指标与性状的相关性。结果表明:1)T_(1)土壤中有机质、有效硅及镁、铁、锌、硒等元素含量均显著高于T_(2)(P<0.05)。2)水稻各生育时期,T_(1)水稻叶片的SPAD均显著高于T_(2)(P<0.05),且植株鞘和叶、茎、穗各部位N、P、K养分的吸收和积累也显著高于T_(2)(P<0.05)。3)拔节-成熟期,T_(1)水稻单穴干物质重显著低于T_(2)(P<0.05),而单茎干物质重则显著高于T_(2)(P<0.05)。4)T_(1)籽粒中ADPG焦磷酸化酶和可溶性淀粉合成酶在灌浆后期仍能保持较高的活性,而谷氨酰胺合成酶在籽粒整个灌浆进程中酶活性均显著高于T_(2)(P<0.05)。5)T_(1)条件下稻米的17种氨基酸含量及Mg、Fe、Zn、Se等元素含量均显著高于T_(2)(P<0.05);T_(1)稻米的垩白米率、垩白度、粗蛋白含量均显著低于T_(2)(P<0.05),整精米率和食味评分均显著高于T_(2)(P<0.05);T_(1)土壤可使水稻籽粒淀粉的峰值粘度升高,同时降低了籽粒淀粉的最低粘度、衰减值和回生值等淀粉RVA特征值。综上,火山熔岩石板田土壤环境可促使水稻植株光合能力及水稻单茎干物质积累量升高、促进植株对N、P、K养分及天然腐殖土中营养元素的吸收和积累、增加整个灌浆结实期或灌浆后期淀粉形成的关键酶代谢活性,进而改善稻米品质。

A novel material, alumina supported on carbon nanotubes (Al2O3/CNT), was prepared from carbon nano-tubes and A1(NO3)3. X-ray diffraction (XRD) spectra demonstrate that alumina is amorphous, and scanning electron microscope (SEM) images show that CNT and alumina are homogeneously mixed. Furthermore, the fluoride adsorption behavior on the surface of Al2O3/CNT has been investigated and compared with other adsorbents. The results indicate that Al2O3/CNT has a high adsorption capacity, with a saturation adsorption capacity of 39.4 mg/g. It is also found that the adsorption capacity of Al2O3/CNT is 3.0-4.5 times that of γ-Al2O3 while almost equal to that of IRA-410 polymeric resin at 25°C . The adsorption isotherms of fluoride on Al2O3/CNT fit the Freundlich equation well, and optimal pH ranging from 5.0 to 9.0.

Hydrogen adsorption experiments were carried out in special stainless steel vessels at room temperature (298K) and under 10 MPa using self-synthesized multi-walled carbon nanotubes. In the experiments, carbon nanotubessynthesized by the seeded catalyst method were pretreatedby being soaked in chemical reagents or annealed at hightemperature before they were used to adsorb hydrogen, but their capacity for hydrogen storage was still poor. Carbonnanotubes synthesized by the floating catalyst method were found to be able to adsorb more hydrogen. They have ahydrogen storage capacity of over 4% after they wereannealed at high temperatures, which suggested that theycould be used as a promising material for hydrogen storage.
