We report the radio observations of the eclipsing black widow pulsar j1720-0534, a 3.26 ms pulsar in orbit with a low mass companion of mass 0.029 to 0.034 m⊙. We obtain the phase-connected timing ephemeris and polarization profile of this millisecond pulsar(mSP) using the Five-hundred-meter Aperture Spherical radio Telescope(FAST), the Green Bank Telescope(GBT), and the Parkes Telescope. For the first time from such a system, an oscillatory polarization angle change was observed from a particular eclipse egress with partial depolarization, indicating 10-milliGauss-level reciprocating magnetic fields oscillating in a length scale of 5 ×10^(3)km(assuming an orbital inclination angle of 90°) outside the companion's magnetosphere. The dispersion measure variation observed during the ingresses and egresses shows the rapid raising of the electron density in the shock boundary between the companion's magnetosphere and the surrounding pulsar wind. We suggest that the observed oscillatory magnetic fields originate from the pulsar wind outside the companion's magnetosphere.

【目的】明确海南海尾湾海域浮游植物群落组成及其与环境因子的相关性,为保护海尾湾海域浮游植物多样性和水体环境提供参考依据。【方法】于2019年7月(夏季)和9月(秋季)及2020年7月(夏季),对海南岛海尾湾近岸海域的12个固定采样点(站点)进行3个航次的水样采集调查,返航后对浮游植物的群落结构、水质及周边环境等进行鉴定和记录,并通过冗余分析(RDA)探究浮游植物群落结构与环境因子的相关性。【结果】2019—2020年的夏季航次采集水样共鉴定出浮游植物4门147种,以硅藻门种类(121种)为主,其次是甲藻门(18种);优势种包括旋链角毛藻(Chaetoceros curvisetus)、菱形海线藻(Thalassionema nitzschioides)、佛氏海毛藻(Thalassiothrix frauenfeldii)、并基角毛藻(***)、奇异棍形藻(Bacillaria paradoxa Gmelin.)、冰河星杆藻(Alexandrum catenclla)及拟旋链角毛藻(***)等;各调查站位浮游植物的平均细胞密度为17.50×104cells/m3,Shannon-Wiener多样性指数(H’)介于3.07~4.33,Pielou均匀度指数(j’)介于0.58~0.85,丰富度指数(D)介于1.34~5.12。2019年秋季航次共鉴定出浮游植物3门86种,其优势种包括旋链角毛藻、拟旋链角毛藻、覆瓦根管藻(Rhizosolehia imbricata ***)、细弱海链藻(Thalassiosira subtilis)、中华根管藻(Rhizosolenia sinensis)及菱形海线藻等;各调查站点浮游植物的平均细胞密度为53.80×104cells/m3,H’介于1.80~3.35,j’介于0.33~0.63,D介于1.66~3.39。影响海尾湾海域浮游植物的重要环境影响因子是水温、SiO4和NH4-N;RDA分析结果表明,旋链角毛藻群落结构与SiO4和COD呈正相关,而拟旋链角毛藻群落结构与水温、化学需氧量(COD)和pH呈正相关。【结论】2019年夏季—2020年夏季海南海尾湾海域的水生环境良好,浮游植物物种丰富度高,影响海尾湾海域浮游植物的重要环境影响因子是水温、SiO4和NH4-N。因此,在掌握海尾湾海域内环境因子与浮游植物种群结构间的相互关系后,应定期重点监测海尾湾海的SiO4和NH4-N变化,避免赤潮发生,同时更需要有针对性地对海水养殖业废水及生活污水进行检测和治理。
