A Contrastive Study of Hedges in English Theses for M.A. Degree

The study ventures to probe into the incidence of hedges in the conclusion part of English theses on the basis of carefully chosen samples, two self-compiled English theses corpora, namely, the Corpus of Native English Speakers (CNES) and the Corpus of Chinese English Learners (CCEL). The findings clearly indicate that hedges used in CCEL shares some similarities with those in CNES, but the differences between them outweigh the similarities. This paper aims to raise Chinese EFL students' awareness of hedges and improve their skills in thesis writing.

第三文化视阈下的跨文化管理研究——以主题公园产业为例

以美国为代表的主题公园产业正向全球特别是欧洲和亚洲发展。然而忽略文化差异的美国商业模式简单转移在其扩张发展中屡遭挫折。全球化进程中的文化因素，特别是“第三文化”在主题公园全球发展中产生着重要影响。所谓“第三文化”模式，并不是把两类文化简单相加，而是拥有自我特征的第三种文化。事实证明，全球主题公园跨国管理正在经历第三文化建立的过程。     

基于DDMZM的星载微波光子混频器设计

微波部件由于分布式参数的影响，存在一定的频率选择性，难以实现宽带多频段兼容的变频系统，已不能满足高通量星载通信载荷的需求。微波光子技术以其大带宽和无频率选择性的优势为高通量天基通信需求的实现提供了可能性。基于双驱动马赫增德尔调制器(DDMZM）对星载通信转发设备混频单元的方案进行探索，通过理论分析链路模型，使用VPI软件对链路进行仿真优化来寻找DDMZM的最佳偏置点。试验结果表明调制器偏置在最小点时，变频效率高，且具有一定的载波抑制功能，可实现宽带、多频段以及抗干扰等性能，优于微波变频性能。     

A topside investigation over a mid-latitude digisonde station in Cyprus

We examine the systematic differences between topside electron density measurements recorded by different techniques over the low-middle latitude operating European station in Nicosia, Cyprus (geographical coordinates: 35.14^oN, 33.2^oE), (magnetic coordinates 31.86^oN, 111.83 ^oE). These techniques include space-based in-situ data by Langmuir probes on board.European Space Agency (ESA) Swarm satellites, radio occultation measurements on board low Earth orbit (LEO) satellites from the COSMIC/FORMOSAT-3 mission and ground-based extrapolated topside electron density profiles from manually scaled ionograms. The measurements are also compared with International Reference Ionosphere Model (IRI-2016) topside estimations and IRI-corrected NeQuick topside formulation (method proposed by Pezzopane and Pignalberi (2019)). The comparison of Swarm and COSMIC observations with digisonde and IRI estimations verifies that in the majority of cases digisonde underestimates while IRI overestimates Swarm observations but in general, IRI provides a better topside representation than the digisonde. For COSMIC and digisonde profiles matched at the F layer peak the digisonde systematically underestimates topside COSMIC electron density values and the relative difference between COSMIC and digisonde increases with altitude (above hmF2), while IRI overestimates the topside COSMIC electron density but after a certain altitude (~150 km above hmF2) this overestimation starts to decrease with altitude. The IRI-corrected NeQuick underestimates the majority of topside COSMIC electron density profiles and relative difference is lower up to approximately 100 km (above the hmF2) and then it increases. The overall performance of IRI-corrected NeQuick improves with respect to IRI and digisonde.     

新城镇化背景下实现大遗址保护的对策

大遗址是一类与城镇建设与社会发展紧密相关的文化遗产资源,城镇化建设的指导方向直接影响着大遗址保护的策略.当前,大遗址保护工作在城镇化建设的热潮中机遇与挑战并存.新型城镇化概念的提出为大遗址保护提供了新的思路,它不再仅仅关注城镇化的速度和规模,更是肯定了城市的文化内涵和品格塑造,这有利于大遗址资源在城市改造进程中免遭破坏,进而转化为城市发展的助推力.当前,考古遗址公园建设是政府为文化遗产保护投入找到的一种回馈社会的最佳方式,也是化解遗址保护与城镇建设之间矛盾的最佳途径.郑州商城遗址已对此进行了多年有益的尝试,以此为例,对如何在新城镇化背景下做好遗址保护工作进行一些探索.     

Recent advancements in the EST project

The European Solar Telescope (EST) is a project of a new-generation solar telescope. It has a large aperture of 4?m, which is necessary for achieving high spatial and temporal resolution. The high polarimetric sensitivity of the EST will allow to measure the magnetic field in the solar atmosphere with unprecedented precision. Here, we summarise the recent advancements in the realisation of the EST project regarding the hardware development and the refinement of the science requirements.     

2010年我国房地产业的政策导向与发展趋势

Midday bottomside electron density profiles during moderate solar activity and comparison with IRI-2001

Bottomside electron density (Ne-h) profiles during midday (10–14 h) are analyzed using modern digital ionosonde observations at a low-middle latitude station, New Delhi (28.6N, 77.2E, dip 42.4N), for the period from January 2003 to December 2003, pertaining to moderate solar activity (MSA). Each individual profile is normalized with respect to the peak height and density (hmF2, NmF2) of the F2-region. These profiles are compared with those obtained from the International Reference Ionosphere (IRI-2001) model. Bilitza [Bilitza, D. International Reference Ionosphere 2000. Radio Sci. 36 (2), 261–275, 2001] using both the options namely: Gulyaeva’s model [Gulyaeva, T.L. Progress in ionospheric informatics based on electron density profile analysis of ionograms. Adv. Space Res. 7 (6) 39–48, 1987] and B0 Tab. option [Bilitza, D., Radicella, S.M., Reinisch, B.W., Adeniyi, J.O., Mosert Gonzalez, M.E., Zhang, S.R., Obrou, O. New B0 and B1 models for IRI. Adv. Space Res. 25 (1), 89–95, 2000]. The study reveals that during summer and equinox, the IRI model with B0 Tab. option in general, produces better agreement with the observed median profiles, while the IRI predictions using Gulyaeva’s option, overestimate the electron density distribution at all the heights below the F2-peak. However, during winter, in general, the IRI model, using both the options, reveals shows fairly good agreement with the observations.
