Measurements of brightness temperatures from Advanced Microwave Sounding Unit-A （AMSU-A） temperature sounding instruments onboard NOAA Polar- orbiting Operational Environmental Satellites （POES） have been extensively used for studying atmospheric temperature trends over the past several decades. Inter- sensor biases, orbital drifts and diurnal variations of atmospheric and surface temperatures must be considered before using a merged long-term time series of AMSU-A measurements from NOAA- 15, - 18, - 19 and MetOp-A. We study the impacts of the orbital drift and orbital differences of local equator crossing times （LECTs） on temperature trends derivable from AMSU-A using near-nadir observa- tions from NOAA-15, NOAA-18, NOAA-19, and MetOp-A during 1998 - 2014 over the Amazon rainforest. The double difference method is firstly applied to estimation of inter-sensor biases between any two satellites during their overlapping time period. The inter-calibrated observations are then used to generate a monthly mean diurnal cycle of brightness temperature for each AMSU-A channel. A diurnal correction is finally applied each channel to obtain AMSU-A data valid at the same local time. Impacts of the inter-sensor bias correction and diurnal correction on the AMSU-A derived long-term atmospheric temperature trends are separately quantified and compared with those derived from original data. It is shown that the orbital drift and differences of LECT among different POESs induce a large uncertainty in AMSU-A derived long-term warming/cooling trends. After applying an inter-sensor bias correction and a diurnal correction, the warming trends at different local times, which are approximately the same, are smaller by half than the trends derived without applying these corrections.

The possibility of using Pb-electroplated reticulated SiC as the positive current collector for lead-acid batteries was investigated. Reticulated SiC with two aperture sizes (3 and 2mm) were tested as the substrate of positive electrode. It was found that the reticulated SiC has an excellent corrosion resistance in H2SO4 solution, and the Pb layer electroplated on reticulated SiC showed analogous electrochemical behavior to metal Pb. Preliminary test of the battery performance indicated that the utilization efficiency of the positive active mass of new designed batteries are improved compared with the conventional batteries. The improvement could be ascribed to the high specific surface area of the reticulated structured positive current collector, which was further supported by the even better performance of the battery made from a smaller aperture size (2mm) reticulated SiC as the substrate of the positive electrode.

A reactive co-deposition processing for obtaining high-quality single-phase Bi2Sr2Cax-1CuxOy （Bi2212） thin films has been investigated using molecular beam epitaxy （MBE） with 2.7 ×10^-3pa ozone gas introduction for oxidation. The thin films with a constant composition of almost 2 ： 2 ： 1 ： 2 were designed to be fabricated at the substrate temperature between 675 and 780℃, the substrate temperature dependence of the surface morphology and the emergence phases were investigated in detail. A noticeable result is that the distribution of Cu element in the thin films is sensitively changed with the substrate temperature. At 750℃ it is inclined to locate in the periphery of each grain through the diffusion process. At 780℃ the Cu-compositional fluctuation brought around the dendritic crystal growth in the thin films. Below 705℃, the Bi2212 single-phase cannot be achieved in the thin films.

Amino compounds （ACs）, i.e., amino acids and amino sugars, are the major forms of organic nitrogen （N） in animal manure and soil. To increase our understanding on the effect of long-term poultry litter （PL） application on soil AC pools and turnover, in this study, we determined the contents of 21 ACs in 23 PL samples, i5 soil samples collected from 0-20, 20-40, and 40-60 cm layers of five pasture plots with 0, 5, 10, 15 and 20 years of PL applications, and 5 grass shoot samples grown on these pasture fields. The contents of 21 ACs were simultaneously determined by methanesulfonic acid hydrolysis/extraction and anion chromatography-pulsed amperometry. PL application increased soil total and individual AC contents with a distribution pattern similar to that of AC in PL. The highest AC-N concentrations were observed in the soils with 10- or 15-year PL applications, inconsistent with the order of annual application rates or eunmlative applied PL amounts. Application of PL increased the AC contents in grass shoots whereby the highest increase of most ACs was with the shoots from the fields that received PL for 5 years. These observations suggested that both freshly applied and residual PL had contributions to the soil AC-N, and that PL application also accelerated AC-N transformation in soil.

Pre-S2 protein and its antibody were detected in 130 children with hepatitis B virus (HBV) infection and 30 with T6 hepatitis B (HB) vaccination. The resuits showed that pre-S2 was positive in most chronic persistent hepatitis (CPH) and chronic active hepatitis(CAH) patients, while anti-pre-S2 was positive in only 8% (2/92 cases) and 11.5% (3/26 cases) respectively. The positive rate of anti-pre-S2 was 78.9%(15/19 cases) in cases at the convalescent stage of acute hepatitis B, 91.7% (55/60 cases) in eases with T6 HB vaccination and 83.3%(25.30 cases) in naturally acquired anti-HBs children, while pre-S2 was not noted. Anti-pre-S2 was negatively related to ALT and positively to anti-HBs (P<0.01). The positive relation of pre-S2 to HBsAg was observed. These results suggest that pre-S2 could be a marker for HBV infection, and anti-pre-S2 may indicate a favourable prognosis of HBV infection. There was no correlation between anti-pre-S2 and pathogenic damages induced by HBV.

近来，基于全球定位系统（ＧＰＳ）提出了一种遥感水汽的新途径。根据ＧＰＳ折射率测量结果能够反演出温度和水汽和垂直廓线。对于气象部门来说，这是一种有价值的潜在资料源。基于宾州／ＮＣＡＲ的中尺度模式的绝热版本及其伴随模式发展了一种四维资料同化系统。然后，进行了一系列观测系统模拟试验来评估ＧＰＳ推算的大气折射资料的效果。结果表明，大气折射率同化在反演水汽垂直廓线中是非常有效的。推算出的水汽场的精度明显比用传统反演技术得到的精度要好。大气折射率同化也能提供有效的温度信息。资料同化结果对于附加在模拟折射率观测值上的随机误差较不敏感。而它们对于观测值的空间分辨率却非常敏感。谱分析表明，湿度场具有较小尺度的变化且对大气折射率观测值的分辨率比温度更敏感。当折射率观测值分辨率较粗时，单个观测值同化得到的结果比在模式格点上内插的观测值同化的结果要好。沿大约２４０ｋｍ距离（ＧＰＳ折射率观测的特征尺度）平均的折射率观测值的同化对温度和湿度场的反演仍得到相当好的结果。
