光学器件性能参数对激光雷达探测气溶胶和云退偏比的影响

二向色镜及偏振分光棱镜作为常用的光学器件,近年来在大气探测偏振激光雷达中得到了广泛使用。但两种光学元件性能上的非理想特性与安装时存在的偏振误差夹角等问题在一定程度上会对大气探测后向散射光的退偏比造成影响。针对偏振激光雷达标定中通常只考虑偏振分光棱镜影响的问题,通过仿真模拟分别分析了二向色镜、偏振分光棱镜以及二者级联下对大气中气溶胶的退偏比影响,并给出了误差分析。以532 nm和1064 nm两种波长下的沙尘粒子与卷云的后向散射光作为输入进行模拟计算,结果显示,常用的长波通二向色镜对模拟输入光源在1064 nm透射通道下有7.111%的退偏比变化,在532 nm反射通道下有3.012%的退偏比变化。对偏振分光棱镜而言,输入为532 nm及1064 nm处探测的沙尘粒子退偏比会分别产生21.333%和27.3%的相对误差变化,532 nm处探测的卷云退偏比会产生14.2%的相对误差变化。两种光学元件在存在偏振误差夹角时均会带来额外的退偏比误差增量,在两种光学元件级联条件下,对模拟光源的退偏比也表现出累加性的误差增大。

Effect of annealing treatment on morphologies and gas sensing properties of ZnO nanorods

The high-temperature stabilization of ZnO nanorods synthesized by hydrothermal treatment was investigated. The structure and morphologies of ZnO nanorods were characterized by XRD and SEM, respectively. The thermal stability of ZnO nanorods was also detected by thermal gravity analyzing. Thermal annealing treatment results indicate that ZnO nanorods are fundamentally stable when annealing temperature is lower than 600 ℃. When annealing temperature is beyond 600℃, the diameters of ZnO nanorods obviously decrease and the aggravating tendency of nanorods between each other also increase. Annealing treatment can greatly influence the gas sensing properties of ZnO nanorods. Comparing with ZnO nanorods without annealing treatment, the gas sensing property of ZnO nanorods to H2 with concentration of 2.5×10-6 can increase from 2.22 to 3.56. ZnO nanorods annealed at 400 ℃ exhibit optimum gas sesing property to H2 gas.

Effects of in situ Annealing on Optical and Structural Properties of GaN Epilayers Grown by HVPE

Effects of in situ annealing on the structural and optical properties of Gallium nitride （GaN） layers grown on （0001） sapphire by hydride vapor phase epitaxy （HVPE） are studied. The properties of GaN epilayers are improved by insitu annealing at growth temperature under ammonia （NH3） atmosphere. X-ray diffraction （XRD） analysis shows that the full width at half maximum （FWHM） of the rocking curves narrows as the annealing time increases. Raman scattering spectroscopy shows that E2 （high） peak positions shift to the low frequency region. Compared to without annealing and epilayers annealed with bulk GaN,the E2 （high） peak position of epilayers becomes closer to that of bulk GaN as the in situ annealing time increases. The biaxial compressive stress decreases after in situ annealing. Photoluminescence （PL） examination agrees well with XRD and Raman scattering analyses. These results suggest that the optical and structural properties of GaN epilayers can be improved by in situ annealing.

Ethanol sensing properties of Bi_(3.15)Nd_(0.85)Ti_3O_(12) films at low operating temperatures

Bi3.15Nd0.85Ti3O12 (BNdT) films were deposited on Pt/Ti/SiO2/Si(100) substrates by a metal organic decomposition (MOD)method, and annealed by a rapid thermal annealing process in oxygen atmosphere and in air, respectively. The crystalline structuresand morphologies of BNdT films were characterized by X-ray diffraction and field-emission scanning electron microscopy, and thegas sensing properties were measured by monitoring its resistance at different gas concentrations. The results indicate that the BNdTfilms annealed in air are of porous microstructure and rough surface, and the annealing atmosphere has great influence on gas sensingproperties. At an operating temperature of 100 °C, the BNdT films annealed in air are of high response value to 1×10?6 gaseousethanol, and the detecting limit is as low as 0.1×10?6. The corresponding response and recovery time is about 10 and 6 s, respectively.The results can offer useful guidelines for fabricating high performance ethanol sensors.

Revisiting Sustainable Development of Dry Valleys in Hengduan Mountains Region

Dry valleys are a striking geographic landscape in Hengduan Mountains Region and are characterized by low rainfall, desert type of vegetation and fragile environment. Past efforts and resources have been concentrated mainly on rehabilitation of degraded ecosystem and fragile environment, particularly reforestation, while socio-economic development has been largely overlooked. Despite successes in pocket areas, the overall trend of unsustainability and environmental deterioration are continuing. It is important to understand that uplift of the Tibetan Plateau is the root cause of development of dry valleys, and development and formation of dry valleys is a natural process. Human intervention has played a secondary role in development of dry valleys and degradation of dry valleys though human intervention in many cases has speeded up environmental degradation of the dry valleys. It is important to understand that dry valleys are climatic enclaves and an integrated approach that combines rehabilitation of degraded ecosystems and socio-economic development should be adopted if the overall goal of sustainable development of dry valleys is to be achieved. Promotion of niche-based cash crops, rural energy including hydropower, solar energy, biogas and fuelwood plantation is recommended as the priority activities.

Energy Spectrum of a Degenerate Fermi Gas at the BEC-BCS Crossover

A theoretical study of the BCS-BEC crossover is presented. Starting from a two-channel Boson-Fermion resonance model, the BCS-Bogoiubov mean-field method and the Green＇s function method are adopted. The result shows that we can end up with a BCS-type theory but with a composite order parameter. Calculation shows that the Bose condensate of BCS Cooper pairs is proportional to the molecular BEC of Bose molecules. The resonance superfluid phase is indicated by the energy spectrum with an obvious interpretation of the transition mechanism.

一种萃取酒醅中低沸点挥发性成分的方法

分别采用水蒸汽蒸馏(SD)法、超声辅助溶剂萃取(UASE)法和蒸馏-微溶剂萃取(SD-MSE)法从浓香型白酒酒醅中提取挥发性成分,利用峰面积归一化法测定各成分的相对含量,通过对挥发性成分的气相色谱-质谱连用/自动化退卷积系统(GC-MS/AMDIS)对比分析。结果表明,SD、UASE及SD-MSE法分别鉴定出42种、71种、60种挥发性成分。SD、UASE及SD-MSE法分别测得的醇、酸、酯的相对含量分别为1.34%、6.61%、21.67%;1.03%、39.28%、37.42%;3.96%、9.97%、64.97%。由此可知,SD法对酸、酯的提取效果劣于另两种方法,UASE法对酸类物质萃取效果更佳,SD-MSE法对酯类物质的萃取效果更佳。和UASE法相比,SD-MSE法节约了大量溶剂,减少了样品转移次数,且待测液澄清透明,是一种适宜萃取糟醅中低沸点成分的方法。

Improvement of deformation capacity of gas-atomized hypereutectic Al-Si alloy powder by annealing treatment

Gas-atomized pure metal or alloy powders are widely used as raw material in the preparation of high performance materials by powder metallurgy route（compaction and sintering）. However, cold compactibility of gas-atomized Al-Si alloy powder is inhibited due to the high strength as a result of the refined Si phases and the supersaturated Al matrix. The effect of annealing on improving the compactibility of Al-Si alloy powder was studied. The densification was investigated by the HECKEL compaction equation in terms of deformation capacity. Moreover, the microstructures and bending fracture surfaces of the green compacts were examined to clarify the densification behavior. The results show that a maximum relative density of 96.1% is obtained when the powder is annealed at 400 °C. The deformation capacity is significantly improved by annealing treatment due to the softening of Al matrix, precipitation of supersaturated Si phases, dissolution of needle-like eutectic phase, and spheroidization of Si phases.

Shocks and Solitons in Ultradense Degenerate Electron-Positron-Ion Plasmas

The formation and propagation of shocks and solitons are investigated in an unmagnetized, ultradense plasma containing degenerate Fermi gas of electrons and positrons, and classical ion gas by employing Thomas-Fermi model. For this purpose, a deformed Korteweg-de Vries-Berger （dKdVB） equation is derived using the reductive perturbative technique for cold, adiabatic, and isothermal ions. Localized analytical solutions of dKdVB equation in planar geometry are obtained for dispersion as well as dissipation dominant cases. For nonplanar （cylindrical and spherical） geometry, time varying numerical shock wave solution of dKdVB equation is found. Its dispersion dominant case leading to the soliton solution is also discussed. The effect of ion temperature, positron concentration and dissipation is found significant on these nonlinear structures. The relevance of the results to the systems of scientific interest is pointed out.

Quasiparticle Spectrum of Quantum Degenerate Fermi Gas in the Presence of Self—Consistent Magnetization Field

In this paper, we develop a systematic and simple method to derive quasiparticle spectrum of the quantum degenerate Fermi gases within the framework of Hartree–Fock–Bogoliubov theory which turns a general nonlinear two-body interaction Hamiltonian into a bilinear Hamiltonian by introducing certain self-consistent mean fields. Applying the approach, we obtain the quasi-particle spectrum of the model describing the superfluid phase transition that arises when a Feshbach resonance pairing occurs in a dilute Fermi gas in the presence of the magnetization fields and . When the gap parameter Δ is smaller than one or both of the magnetization fields, the spectrum manifests roton-type structure dramatically different from the spectrum in the absence of the magnetization fields.

Growth of Semi-Insulating GaN Using N2 as Nucleation Layer Carrier Gas Combining with an Optimized Annealing Time

Semi-insulating （SI） GaN is grown using N2 as the nucleation layer （NL） carrier gas combined with an optimized annealing time by metalorganic chemical vapour deposition. Influence of using 1-12 and N2 as the NL carrier gas is investigated in our experiment. It is found that the sheet resistance of unintentionally doped GaN can be increased from 10^4 Ω/sq to 10^10 Ω/sq by changing the NL carrier gas from 1-12 to N2 while keeping the other growth parameters to be constant, however crystal quality and roughness of the tilm are degraded unambiguously. This situation can be improved by optimizing the NL annealing time. The high resistance of GaN grown on NL using N2 as the carrier gas is due to higher density of threading dislocations caused by the higher density of nucleation islands and small statistic diameter grain compared to the one using 1-12 as carrier gas. Annealing the NL for an optimized annealing time can decrease the density of threading dislocation and improve the tilm roughness and interface of AlGaN/GaN without degrading the sheet resistance of as-grown GaN signiticantly. High-quality SI GaN is grown after optimizing the annealing time, and AlGaN/GaN high electron mobility transistors are also prepared.
