    Subjects: Geosciences >> Geography submitted time 2021-06-13 Cooperative journals: 《干旱区研究》

    Abstract:以开都河流域为例,以SWAT(Soil and Water Assessment Tool)分布式水文模型和标准化降水蒸散指数(SPEI)为基础,对干旱变化特征进行识别。利用贝叶斯动态线性方程(BDL)模型研究南方涛动(SOI)等气候驱动因子对区域季节性干旱的影响。结果表明:1965—2016年开都河流域的干旱主要集中于冬、春季;在不同季节,流域干旱的变化趋势也有所不同,但趋势并不明显,仅在秋冬季可以检测出显著下降的趋势;不同季节的SPEI指数变化受降水、潜在蒸散发等气候因素的响应较快,多在0值上下波动,导致其变化周期较短,多集中在2~4 a;气候指数对流域干湿变化的影响随着时间的推移而转变,对不同季节的影响也有所不同。

  • 负压封闭引流联合肝素灌洗治疗兔烫伤并海水浸泡创面

    Subjects: Medicine, Pharmacy >> Preclinical Medicine submitted time 2017-12-07 Cooperative journals: 《南方医科大学学报》

    Abstract: Objective To investigate the effect of closed vacuum drainage combined with heparin irrigation in the treatment of scald burns with seawater immersion in rabbits. Methods Twenty New Zealand rabbits were subjected to deep partial-thickness scald burns in 4 regions on the bilateral skin of the spine. The wounds were managed with common dressing (group A), common dressing after seawater immersion (group B), closed vacuum drainage after seawater immersion (group C), or closed vacuum drainage combined with heparin irrigation after seawater immersion (group D). Wound effusion and tissue necrosis were observed at 1, 3, 5 and 7 days after the burns. Tissue samples were collected from the wounds for HE staining and immunohistochemistry for VEGF and CD31, and the changes of capillary endothelial cells in the wound were observed using electron microscopy. The water content in the wound tissues was determined, and the wound healing rate was calculated after the injury. Results Sea water immersion of the wound results in earlier onset of edema and more extensive tissue necrosis in the scalded rabbits. The mean necrotic area in groups C and D was smaller than that in group B early after the burns, and vacuum drainage promoted necrotic tissue elimination and accelerated wound healing. Early after the burns, water content in the tissues increased with time in all the groups and reached the highest level at 3 days, and was significantly lower in groups C and D than in group B. Pathologically, vascular endothelial cell damage at the wound site was worsened after seawater immersion. In group D, the basement membrane damage was milder and the endothelial cell membrane remained intact at the wound site, where new blood vessels occurred at 3 days after the burns, a time earlier than that in the other 3 groups with also the highest vascular density. Conclusion Closed vacuum drainage combined with heparin irrigation can relieve edema at the scald wound with seawater immersion, improve microcirculation, accelerate the removal of necrotic tissue, and promote the growth of new blood vessels.

  • Broadband Dual-polarization Vivaldi Feed Design for QTT 110 m Radio Telescope

    Subjects: Astronomy submitted time 2024-01-31 Cooperative journals: 《天文学报》

    Abstract: Radio telescopes usually conduct continuous observation across a wide frequency range, but traditional phased array antenna designs struggle to meet the requirements of both wide band and large scanning volume. The development of tightly coupled antennas offers a novel approach for addressing these challenges. Accordingly, a wideband dual-polarized Vivaldi phased array feed has been designed. Firstly, a theoretical analysis of the tightly coupled principle is conducted, incorporating Wheeler's concept of continuous current and equivalent circuit. It reveals that the strong coupling between the antenna elements effectively expands the operational bandwidth of the Vivaldi phased array. Based on this, a wideband Vivaldi phased array feed composed of 8\times9 Vivaldi antenna elements with a operational frequency ranging from 2 to 8 GHz is designed. Furthermore, the phased array enables \pm45^\circ scanning characteristics in both E-plane and H-plane. Finally, a prototype of the phased array is fabricated and measured. The measurement results are in good agreement with the simulated ones.

  • Identification of COVID-19 Infection in Vulnerable Population and Its Prevention and Treatment Perspectives

    Subjects: Medicine, Pharmacy >> Clinical Medicine submitted time 2023-07-05 Cooperative journals: 《中国全科医学》

    Abstract: The COVID-19 pandemic has devastated human health and global economy. Diminished immune function of health-related vulnerable populations leads to insufficient protective effect of the vaccine with a higher risk of severe illness and death following infection,and there is a lack of adequate targeted drugs for the prevention and treatment of COVID-19. In the context that COVID-19 treated as a Category B disease in China,vulnerable populations have become the priority populations for epidemic prevention and control. Therefore,the strategies of individual immunization and prevention should be further optimized for vulnerable populations. In addition to vaccines,other prevention strategies should be supplemented,such as long-acting neutralizing antibodies. Based on this,this paper reviews the identification,immune function characteristics and prevention strategies of COVID-19 in vulnerable populations,to provide a reference for the prevention and control strategies for health-related vulnerable populations in China,expecting that more suitable preventive drugs for vulnerable populations can be developed in the future to reduce the risk of COVID-19 in vulnerable populations.

    Subjects: Library Science,Information Science >> Library Science submitted time 2022-11-13

    Abstract: Objective Scientific data is an important support for the development of science and technology, and information security is a prerequisite for the publication and sharing of scientific data. Sorting out the information security management of the publication and sharing of related data of academic journals in China is helpful to promote the publication and sharing of scientific data. Methods  Based on the evolution of scientific data publishing and sharing in China, and the current situation and development of Journals of Geographic and Resource Science in scientific data sharing, this paper analyzes the publication and security management of related data publishing in academic journals.  Results  To maximize the value of social public scientific data resources, China established a top-down scientific data sharing system, including network infrastructure, database, data center, and data service platform, developed a series of data acquisition and management practices, and made the laws of scientific data and information security.  Conclusion Scientific data publishing and sharing should be built on the basis of security. After the initial large-scale construction, data publishing and sharing and its security management should move to the stage of “improving quality and efficiency” to ensure data quality and increase utilization efficiency. Attention should be paid to the injection of high-tech and professional personnel training.

  • Development and testing of 4-element microstrip antenna array

    Subjects: Astronomy >> Astrophysical processes submitted time 2023-01-17 Cooperative journals: 《天文研究与技术》

    Abstract: The array antenna is placed at the focal plane of the radio telescope and combined with the beam forming network to observe a sky area at the same time to achieve greater field of view coverage. Because the amplitude and phase of each element need to be adjusted, the array antenna is actually a small phased array. Therefore, when designing the array, in addition to combining the focal field distribution of the telescope and the field of view to be achieved by the telescope, the performance verification of the array itself can refer to the traditional phased array. This paper designs a 2 × 2 rectangular microstrip patch antenna array with element spacing of 0.7 times the wavelength. The measured results show that the S11 of each port is all below -10dB, and the beam gain after the beamforming of 4 elements is 12.54dBi. By adding a delay line with a theoretical deviation of 30 degrees to the corresponding element, the beam scanning angle of the array is 28.3 degrees. Although the measured data are slightly different from the simulation results, which is related to array fabrication and feed port welding, the related work has accumulated experience for the design, development and testing of array antenna with more elements, and it has a good guiding significance for performance verification.

  • Research on Mutual Coupling Effect of Array Antennas

    Subjects: Astronomy >> Astrophysical processes submitted time 2022-05-30 Cooperative journals: 《天文研究与技术》

    Abstract:相控阵馈源是将阵列天线放置于射电望远镜焦面场处,用以实现更高增益及更灵活波束调控的接收机技术。鉴于其与阵列天线一样,是由多个天线单元以一定方式组合排列而成,工作时阵元之间产生电磁耦合在所难免。本文选用螺旋天线作为阵列天线单元,工作频率为1.25GHz,对独立天线进行仿真优化后,该天线-10dB阻抗带宽仅为70MHz。依托该天线单元建立55矩形排布螺旋天线阵列模型,分别选取阵元间距为1、0.5、0.25、0.125倍波长(1.25GHz@0.24m),以此验证不同阵元间距下的互耦效应对整个阵列带宽的影响。最终通过对各阵元输入阻抗进行匹配,仿真得到在0.25倍波长间距下,阵列中心阵子的-10dB阻抗带宽可扩展至550MHz,而阵列天线的带宽也基本表征了将其用作相控阵馈源的工作带宽。上述工作加深了对阵列天线带宽特性的理解,也为实际应用于射电望远镜系统的相控阵馈源实现更宽的工作带宽提供了可能。

    Subjects: Astronomy >> Astrophysical processes submitted time 2021-09-29 Cooperative journals: 《天文研究与技术》

    Abstract:射电天文接收机中频系统是接收机的重要组成部分,接收机的L、S、C、K波段的左圆极化和右圆极化信号在高频仓通过下变频成为中频信号。中频信号通过同轴电缆传送到观测室。观测室距离射电望远镜高频仓较远,因此线损较大,且不同频率的信号损耗不同,频率越高损耗越大,导致中频信号功率较小且增益平坦度随频率增加而降低。设计了四通道均衡放大模块,提高中频信号增益并补偿增益平坦度。该模块的均衡器采用了集总元件和微带线相结合的方式,具有结构紧凑、易于集成、成本低的优点。测试结果表明,在6倍频带宽内,均衡量≥8dB,均衡后功率平坦度≤3.5dBm,回波损耗≤-15dB,满足了射电天文中频检测系统的要求。

  • 银川平原夏半年不同等级降雨水汽输送机制

    Subjects: Geosciences >> Geography submitted time 2024-03-01 Cooperative journals: 《干旱区研究》

    Abstract: Global warming intensifies regional water cycles and alters water vapor transport routes. Investigatingstable isotope traits in diverse precipitation grades and identifying water vapor origins can offer insights forefficient water resource utilization and drought- flood management. By analyzing precipitation samples fromYinchuan Plain in the May- October summer half- years of 2018- 2020, the hydrogen and oxygen isotopefluctuations across precipitation levels and their secondary evaporation effects were estimated in this study.Backward trajectory modeling and water vapor flux methods were applied to determine vapor sources andpotential evaporation areas. The findings revealed that the stable isotope signature in Yinchuan Plain during thesummer half-year decreased with increased rainfall levels; light rain exhibited negative d-excess values, whereasmoderate and heavy rains showed positive values. The slope and intercept of the regional atmosphericprecipitation line diminished as rainfall magnitude increased. Secondary evaporation intensified with higher airtemperature, but decreased with increased precipitation, air relative humidity, and raindrop diameter. Distinctwater vapor origins existed across precipitation levels: westerly vapor dominated light rain, whereas moderateand heavy rains originated not only from westerly vapor but also from high latitude land evaporation vapor andsoutheast ocean vapor, respectively. Potential evaporative vapor source areas predominantly influenced light andmoderate rainfall, encompassing the study area’s vicinity as well as northwest and southeast regions. Moderaterainfall events were largely observed in the study area’s vicinity, as well as northwest and southeast regions,whereas heavy rainfall clustered around the study area and the southeastern region.

  • K波段常温接收机噪声注入定标方法分析研究

    Subjects: Astronomy >> Astrophysical processes submitted time 2020-05-12 Cooperative journals: 《天文研究与技术》

    Abstract:噪声注入定标方法作为厘米波段一种常规强度校准方式而被广泛使用。通过组建K波段常温接收机及其定标平台,在室内20℃下使用传统冷热负载法标定接收机噪声温度及噪声源温度,之后在室外-7℃中使用同样方法再次标定上述参数,并利用室内标定的噪声源去进一步标定室外环境中接收机的噪声温度。测试结果表明,在环境温度变化约27度时,接收机噪声温度定标差异约为50.5%,标准噪声源定标差异约为41%。故此得知,如若将噪声注入法应用于常温接收机定标中,首先需考虑对接收机进行恒温处理,另外可采取对注入的标准噪声源进行温度补偿,使其可以更加精确的应用于二次定标当中,这也是本论文下一步计划开展的工作。

    Abstract: Phased array feed is a new array antenna receiving system in the field of radio astronomy in recent years. It is a kind of small electric antenna unit array arranged in rect#2;angular, hexagonal and other ways on the focal plane of radio telescope. It applies different excitation to each array element through beam combination, and regulates the amplitude and phase of each array element, so that each beam overlaps with each other and the phase center is close to each other. In order to improve the efficiency of sky survey, the focal plane area can be fully sampled to achieve continuous field of view coverage. Starting from focal plane array, this paper introduces the phased array feed and multi-beamed technology, and then describes in detail the advanced research of phased array feed technology development in the world, including NRAO in the United States, ASTRON in the Netherlands, DRAO in Canada and CSIRO in Australia, etc. And then introduces the technology pre-research and engineering practice of phased array feed which are carried out under the promotion of large scientific device and projects such as SKA. Finally, according to the development of existing phased array feed technology, the future research difficulties and development direction of this technology are proposed.

  • Study of the Proton Resonant States in 23Mg via 22Na+p Thick-Target Elastic Scattering

    Subjects: Physics >> Nuclear Physics submitted time 2024-01-09

    Abstract: In Orgueil meteorites, an exceptionally high 22Ne/20Ne abundance ratio or even nearly pure 22Ne is ob#2;served, which is the so-called Ne extraordinary problem. Fossil material of extinct 22Na is believed to be the origin of extraordinary 22Ne, these 22Na nuclides were trapped in grains and incorporated into meteorites in stellar explo#2;sive event. Supernovae and neon-rich novae are the primary events, which are responsible for the production of 22Na through the explosive hydrogen burning process. 22Na(p, γ)23Mg and 19Ne(α, p) 22Na are two crucial reactions in the so-called NeNa-MgAl cycle and the rapid-proton process, which lead to the fast nucleosynthesis up to A=100 nuclide region and the outburst of novae and X-ray bursters. Since many proton resonance levels in odd-A compound nucleus 23Mg may be involved at nova temperature, existing measurements can only provide partial effective information on the 22Na(p, γ)23Mg reaction. Large uncertainties still exist in the astrophysical reaction rates of the two reactions at present. Thick target inverse kinematics method is a very effective way to scan the 23Mg proton resonance levels re#2;lated to the 22Na(p, γ)23Mg reaction via the excitation function of 22Na(p, p) elastic scattering, which could be obtained over a large energy range in one-shot measurement with low-intensity radioactive 22Na beam. In the present work, 22Na+p resonance scattering via thick target inverse kinematics was studied at RIBLL1 radioactive beam line in the HIRFL national laboratory at Lanzhou. A high-purity 22Na beam with an intensity of about 2 × 105 pps was produced via the 1H(22Ne,22Na)n reaction with an alcohol-cooled hydrogen gas target. Time-of-Flight by two plastic scintillator detectors and two parallel-plate avalanche counters were used to monitor the 22Na secondary beam before reaching the (CH2 )n target. The timing information is useful for beam particle identification and the position information is essen#2;tial for 22Na(p,p) elastic scattering kinematics reconstruction. Light recoil particles from 22Na+p reaction system were detected by two sets of double-sided silicon strip detector telescopes centered at 𝜃lab = 0° and 14°, respectively, while the heavy recoil particles were stopped in the (CH2 )n thick target. Two-body kinematics reconstruction of 22Na(p,p) elastic scattering is performed on the event-by-event basis, and an excitation function of 22Na(p,p) is obtained in the energy range of 𝐸c.m. = 1.5 to 4 MeV. Obvious proton resonance structure is observed in the 23Mg compound nucleus, which will be further analyzed with R-matrix nuclear theoretical model.
