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 Amaz.n 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.

Role of Nitrite in Tumor Growth, Symbiogenetic Evolution of Cancer Cells, and China’s Successes in the War against Cancer

引用

Journal of Cancer Therapy 2011年第5期2卷 601-606页

作者： Kenneth J. Hsu Chao S. Huangfu Min z. qin 不详

Statistics and experiments indicate a correlation between cancer mortality and nitrite in drinking water. Nitrite is a reductant that can deprive a cell of oxygen;it is also an oxidant that can be a substrate in anaerobic ammonium oxidation, the metabolic mode of the anammox bacteria. Eukaryote cells evolved through a fusion of anaerobic and aerobic bacteria. We postulate that an anammox bacterium sought refuge in a fusion with a membrane-bound cluster of aerobic bacteria. While the latter evolved into mitochondria organelles, the former became the nucleus of a prokaryote cell. Eventually, oxidative phosphorilation is the characteristic metabolic pathway of normal eukaryote cells, and we postulate that anammox is the protein-catabolism pathway for cancer cells. The metabolism consumes nitrite and explains thus the link between nitrite and cancer.

To investigate the nature of the Ψ（3770） resonance and to measure the cross section for e^＋e^-→DD, a cross-section scan data sample, distributed among 41 center-of-mass energy points from 3.73 to 3.89 GeV, was taken with the BESIII detector operated at the BEPCII collider in the year 2010. By analyz.ng the large angle Bhabha scattering events, we measure the integrated luminosity of the data sample at each center-of-mass energy point. The total integrated luminosity of the data sample is 76.16±0.04±0.61 pb^-1, where the first uncertainty is statistical and the second systematic.

THE FACTORS AFFECTING ENTROPY OF MIXING OF LIQUID ALLOY SYSTEMS

Acta Metallurgica Sinica(English Letters) 1997年第2期10卷 127-130页

A modified Miedema model using four atomic parameters and pattern recognition or artificial neural network has been used to study the factors that affect the entropy of mixing of liquid binary alloy systems. It has been found that the systems with larger electronegativity difference (△Φ) usuallg have negative △Sxs of mixing, while the systems with larger valence electron density difference(denoted by △n) and small △Φ usually have positive △Sxs of mixing. The artificial neural network-atomic parameter method can be used to predict the △Sxs of binary alloy systems consisting of non-transition elements.

Homologous temperature of olivine: Implications for creep of the upper mantle and fabric transitions in olivine

引用

Science China Earth Sciences 2016年第6期59卷 1138-1156页

作者： WANG qin State Key Laboratory for Mineral Deposits Research School of Earth Sciences and Engineering Nanjing University

The homologues temperature of a crystalline material is defined as T/Tm, where T is temperature and Tm is the melting （solidus） temperature in Kelvin. It has been widely used to compare the creep strength of crystalline materials. The melting temperature of olivine system, （Mg,Fe）2SiO4, decreases with increasing iron content and water content, and increases with confining pressure. At high pressure, phase transition will lead to a sharp change in the melting curve of olivine. After calibrating previous melting experiments on fayalite （Fe2SiO4）, the triple point of fayalite-Fe2SiO4 spinel-liquid is determined to be at 6.4 GPa and 1793 K. Using the generaliz.d means, the solidus and liquidus of dry olivine are described as a function of iron content and pressure up to 6.4 GPa. The change of T/Tm of olivine with depth allows us to compare the strength of the up- per mantle with different thermal states and olivine composition. The transition from semi-brittle to ductile deformation in the upper mantle occurs at a depth where T/Tm of olivine equals 0.5. The lithospheric mantle beneath cratons shows much smaller T/Tm of olivine than orogens and extensional basins until the lithosphere-asthenosphere boundary where T/Tm 〉 0.66, suggesting a stronger lithosphere beneath cratons. In addition, T/Tm is used to analyz. deformation experiments on olivine. The results indicate that the effect of water on fabric transitions in olivine is closely related with pressure. The hydrogen-weakening effect and its relationship with T/Tm of olivine need further investigation. Below 6.4 GPa （〈200 kin）, T/TIn of olivine controls the transition of dislocation glide from [100] slip to [001] slip. Under the strain rate of 10-12-10-15 s-1 and low stress in the upper mantle, the [100]（010） slip system （A-type fabric） becomes dominant when T/TIn〉 0.55-0.60. When T/Tm〈 0.55-0.60, [001] slip is easier and low T/Tm favors the operation of [001]（100） slip system （C-type fabric）. This is consistent with

INVESTIGATION ON DEPOSITIONS AND HARDNESS CHARACTERISTICS OF a-SiC:H FILMS

Acta Metallurgica Sinica(English Letters) 1999年第5期12卷 761-764页

作者： X.F.Rong and z.Y.qin College of Mechanical Engineering,Taiyuan University of Technology, Taiyuan 030024, China Taiyuan Univ of Technology Taiyuan China

In this paper, a deposition feature of a SiC:H films deposited by a RF sputtering system and a effect on the hardness of the films with various deposition conditions are investigated, and the effects of the silicon on a C:H are studied. It follows from the results that the properties of hardness can be changed with the depositing conditions. An increase of silane in the gas phase allows to deposit a SiC:H having tetrahedral structure. The sets of deposition conditions by which the different types of a SiC:H films can be deposited are obtained.
