背架受非均匀温度影响是造成射电望远镜天线主反射面精度下降的重要因素之一.工作于野外的天线由于背架拓扑结构复杂导致杆件间相互存在遮挡、热传导、热辐射等,使得背架结构温度场难以通过热力学仿真来准确获取与预测.通过在南山26 m射电望远镜天线背架上布设测温传感器,得到天线背架温度数据集,利用3种不同的无监督特征选择方法从66个测温点选出16个温度敏感点,再将3组不同的温度敏感点集作为输入,使用多输入多输出的BP(Back Propagation)神经网络模型训练输出对应的66个测温点的预测温度值,通过插值算法实现背架全域连续点的温度预测.经计算对比分析得出采用基于特征值敏感准则无监督特征选择方法选取测温敏感点效果最佳,结合BP神经网络与Barnes插值算法实现了仅用16个实测温度点预测南山26 m射电望远镜天线背架全域连续点的温度场分布,预测均方根误差约为0.707℃.研究成果为大口径射电望远镜天线背架结构温度采集点的布置、温度场的获取及预测提供一种可选方法.

作者： XinYi Rang Chao Xiong YuHao Zheng Jing Liu Yu jiao ShunZu Gao YuYang Huang Xin Wan Fan Yin Department of Space Physics Electronic Information School Wuhan University School of Space Science and Physics Shandong Key Laboratory of Optical Astronomy and Solar-Terrestrial Environment Institute of Space Sciences Shandong University Planetary Environmental and Astrobiological Research Laboratory (PEARL) School of Atmospheric Sciences Sun Yatsen University

In this study, we provide a detailed case study of the X-pattern of equatorial ionization anomaly(EIA) observed on the night of September 12, 2021 by the Global-scale Observations of the Limb and Disk(GOLD) mission. Unlike most previous studies about the X-pattern observed under the severely disturbed background ionosphere, this event is observed under geomagnetically quiet and low solar activity conditions. GOLD's continuous observations reveal that the X-pattern intensity evolves with local time, while its center's longitude remains constant. The total electron content(TEC) data derived from the ground-based Global Navigation Satellite System(GNSS) network aligns well with GOLD observations in capturing the formation of the X-pattern, extending coverage to areas beyond GOLD's observational reach. Additionally, the ESA's Swarm mission show that both sides of the X-pattern can coincide with the occurrence of small-scale equatorial plasma bubbles(EPBs). To further analyze the possible drivers of the X-pattern, observations from the Ionospheric Connection Explorer(ICON) satellite were used. It shows that the latitudinal expansion(or width) between the EIA crests in two hemispheres is proportional(or inversely proportional) to the upward(or downward) plasma drift velocity, which suggests that the zonal electric field should have a notable influence on the formation of EIA X-pattern. Further simulations using the SAMI2 model support this mechanism, as the X-pattern of EIA is successfully reproduced by setting the vertical plasma drift to different values at different longitudes.

The main purpose of this paper is to establish, using the Littlewood–Paley–Stein theory(in particular, the Littlewood–Paley–Stein square functions), a Calderón–Torchinsky type theorem for the following Fourier multipliers on anisotropic Hardy spaces Hp(Rn;A) associated with expensive dilation A:■Our main Theorem is the following: Assume that m(ξ) is a function on Rn satisfying ■with s > ζ--1(1/p-1/2). Then Tm is bounded from Hp(Rn;A) to Hp(Rn;A) for all 0 < p ≤ 1 and ■where A* denotes the transpose of A. Here we have used the notations mj(ξ) = m(A*jξ)φ(ξ) and φ(ξ) is a suitable cut-off function on Rn, and Ws(A*) is an anisotropic Sobolev space associated with expansive dilation A* on Rn.

Let s ： S2 → G（2, 5） be a linearly full totally unramified pseudo-holomorphic curve with constant Gaussian curvature K in a complex Grassmann manifold G（2, 5）. It is prove that K is either 1 4 1 or 4/5 if s is non-±holomorphic. Furthermore, K = 1/3 if and only if s is totally real. We also prove that the Gaussian curvature K is either 1 or -4/3 if s is a non-degenerate holomorphic curve under some conditions.
