O^++ is an interesting species in the ionospheres of both the Earth and Venus. Recent measurements made by the Neutral Gas and Ion Mass Spectrometer (NGIMS) on board the Mars Atmosphere and Volatile Evolution (maven) spacecraft provide the first firm detection of O^++ in the Martian ionosphere. This study is devoted to an evaluation of the dominant O^++ production and destruction channels in the dayside Martian ionosphere, by virtue of NGIMS data accumulated over a large number of maven orbits. Our analysis reveals the dominant production channels to be double photoionization of O at low altitudes and photoionization of O^+ at high altitudes, respectively, in response to the varying degree of O ionization. O^++ destruction is shown to occur mainly via charge exchange with CO2 at low altitudes and with O at high altitudes. In the dayside median sense, an exact balance between O^++ production and destruction is suggested by the data below 200 km. The apparent discrepancy from local photochemical equilibrium at higher altitudes is interpreted as a signature of strong O^++ escape on Mars, characterized by an escape rate of 6×10^22s^-1.

火星逃逸层中性成分经光致电离、电荷交换和电子碰撞产生新生离子,新生离子随即被太阳风和火星磁鞘电磁场拾起,称为“拾起”离子.已有观测表明拾起氧离子(O^(+))在朝向火星沉降途中会被反射,但发生反射的空间位置和反射机制尚不十分明确.若反射离子持续进入探测器,将为我们追踪反射发生的空间位置提供重要机遇.本文将报道这样一个观测实例,2016年9月25日04∶18∶30—04∶24∶54 UT期间,火星大气和挥发物演化任务(Mars Atmosphere and Volatile EvolutioN,maven)运行在-E半球(对流电场E指向火星)的磁鞘区,轨道高度逐渐降低,持续观测到背离火星运动的O^(+)(10^(3)~10^(4)eV)束流,即正在反射的拾起O^(+).反射拾起O^(+)大致可分为两部分:相空间密度较高、能量较低的部分是由磁鞘拾起O^(+)被反射后形成;相空间密度较低、能量较高的部分则源于太阳风拾起O^(+)发生反射后形成.我们推断反射发生在感应磁层边界附近的强磁场区域.

An important population of the dayside Martian ionosphere are photoelectrons that are produced by solar Extreme Ultraviolet and X-ray ionization of atmospheric neutrals.A typical photoelectron energy spectrum is characterized by a distinctive peak near 27 eV related to the strong solar HeⅡ emission line at 30.4 nm,and an additional peak near 500 eV related to O Auger ionization.In this study,the extensive measurements made by the Solar Wind Electron Analyzer on board the recent Mars Atmosphere and Volatile Evolution spacecraft are analyzed and found to verify the scenario that Martian ionosphere photoelectrons are driven by solar radiation.We report that the photoelectron intensities at the centers of both peaks increase steadily with increasing solar ionizing flux below 90 nm and that the observed solar cycle variation is substantially more prominent near the O Auger peak than near the HeⅡ peak.The latter observation is clearly driven by a larger variability in solar irradiance at shorter wavelengths.When the solar ionizing flux increases from 1 mW·m^-2 to 2.5 mW·m^-2,the photoelectron intensity increases by a factor of 3.2 at the HeⅡ peak and by a much larger factor of 10.5 at the O Auger peak,both within the optically thin regions of the Martian atmosphere.

随着互联网的快速发展,中国外汇交易中心也加快了信息化的建设,成立了全资子公司中汇信息技术有限公司。中汇公司成立初期,因为人才短缺引入了大量外包开发人员,这引发了一些问题。第一,外包人员开发的单元模块引入各种版本的第三方JAR包,导致了项目依赖过于庞大和繁杂,并且手动引入耗时耗力。基于这个问题,我们提出了采用maven的依赖管理来进行自动化集成打包。第二,外包人员开发时采用不同的体系架构,导致了各个系统间集成与后期维护的困难。基于这个问题,我们提出了以一个框架来作为外包人员开发的基础。这个框架在基础服务层封装第三方开源或商用的JAR包,处理项目依赖的问题;在基础单元层处理业务单元,在应用原型层进行组装服务层和单元层的内容,打包并部署到应用服务器上进行展示。CWAP框架以maven为项目构建与管理工具,采用J2EE体系结构和Spring框架,采用了MVC模式的设计思想。主要目的是为交易中心、银行间市场、央行等信息系统应用提供成熟的软件服务。通过开发这一套CWAP框架,开发人员就可以复用软件构件,帮助快速响应和实现业务,规范开发过程,达到开发资源的合理利用,提高系统应用的开发效率。本文围绕CWAP框架基础单元层和基础服务层的设计与实现,先进行了需求分析,之后分别对日志管理、账户管理、角色管理、菜单管理、数据库等几个模块的设计进行了详细的描述,并通过类图、代码、界面截图的方式进一步说明了各个模块的具体实现。目前CWAP框架已经发布到2.2版本,交易中心各部门也在逐渐使用CWAP框架来进行系统的开发与改造升级。同时,我们框架开发小组也在继续扩展我们的CWAP框架,来适应更多的新需求。

The photoelectron peak at 22 27 eV, a distinctive feature of the energetic electron distribution in the dayside Martian ionosphere, is a useful diagnostic of solar extreme ultraviolet (EUV) and X-ray ionization as well as of large-scale transport along magnetic field lines. In this work, we analyze the pitch angle distribution (PAD) of energetic electrons at 22 27 eV measured during several representative Mars Atmosphere and Volatile Evolution (maven) orbits, based on the electron spectra gathered by maven’s Solar Wind Electron Analyzer (SWEA) instrument. On the dayside, most photoelectron spectra show an isotropic PAD as is expected from production via solar EUV/X-ray ionization. The photoelectron spectra occasionally observed on the nightside show instead a strongly anisotropic PAD, indicative of cross-terminator transport along ambient magnetic field lines. This would in turn predict the presence of dayside photoelectrons, also with a strongly anisotropic PAD, which was indeed revealed in SWEA data. Comparison with magnetic field measurements made by the maven Magnetometer suggests that on average the photoelectrons with anisotropic PAD stream away from Mars on the dayside and towards Mars on the nightside, further supporting the scenario of day-to-night transport. On both sides, anisotropic photoelectrons tend to be observed above the photoelectron exobase at ~160 km where photoelectron transport dominates over local production and energy degradation.

Doubly charged positive ions(dications)are an important component of planetary ionospheres because of the large energy required for their formation.Observations of these ions are exceptionally difficult due to their low abundances;until now,only atomic dications have been detected.The Neutral Gas and Ion Mass Spectrometer(NGIMS)measurements made on board the recent Mars Atmosphere and Volatile Evolution mission provide the first opportunity for decisive detection of molecular dications,CO2^++in this case,in a planetary upper atmosphere.The NGIMS data reveal a dayside averaged CO2^++distribution declining steadily from 5.6 cm^−3 at 160 km to below 1 cm^−3 above 200 km.The dominant CO2^++production mechanisms are double photoionization of CO2 below 190 km and single photoionization of CO2^+at higher altitudes;CO2++destruction is dominated by natural dissociation,but reactions with atmospheric CO2 and O become important below 160 km.Simplified photochemical model calculations are carried out and reasonably reproduce the data at low altitudes within a factor of 2 but underestimate the data at high altitudes by a factor of 4.Finally,we report a much stronger solar control of the CO2^++density than of the CO2+density.

The CO2^+;ultraviolet doublet(UVD)emission near 289 nm is an important feature of dayside airglow emission from planetaryupper atmospheres.In this study,we analyzed the brightness profiles of CO2^+;UVDemission on Mars by using the extensive observationsmade by the lmaging Ultraviolet Spectrograph on board the recent Mars Atmosphere and Volatle Evolution spacecraft.Strong solar cycleand solar zenith angle variations in peak emission intensity and altitude were revealed by the data:(1)Both the peak intensity and altitude increase with increasing solar activity,and(2)the peak intensity decreases,whereas the peak altitude increases,with increasingsolar zenith angle.These observations can be favorably interpreted by the solar-driven scenario combined with the fact that photoionization and photoelectron impact ionization are the two most important processes responsible for the production of excited-state cotand consequently the intensity of CO2^+;UVDemission.Despite this,we propose that an extra driver,presumably related to thecomplicated variation in the background atmosphere,such as the occurrence of globaldust storms is required to fuly interpret theobservations.In general,our analysis suggests that the CO2^+;UVD emission is a useful diagnostic of the variability of the dayside Martianatmosphere under the influences of both internal and external drivers.
