| 1 | The Soft X-ray Imager(SXI)on the SMILE Mission显示文摘The Soft X-ray Imager(SXI)is part of the scientific payload of the Solar wind Magnetosphere Ionosphere Link Explorer(SMILE)mission.SMILE is a joint science mission between the European Space Agency(ESA)and the Chinese Academy of Sciences(CAS)and is due for launch in 2025.SXI is a compact X-ray telescope with a wide field-of-view(FOV)capable of encompassing large portions of Earth’s magnetosphere from the vantage point of the SMILE orbit.SXI is sensitive to the soft X-rays produced by the Solar Wind Charge eXchange(SWCX)process produced when heavy ions of solar wind origin interact with neutral particles in Earth’s exosphere.SWCX provides a mechanism for boundary detection within the magnetosphere,such as the position of Earth’s magnetopause,because the solar wind heavy ions have a very low density in regions of closed magnetic field lines.The sensitivity of the SXI is such that it can potentially track movements of the magnetopause on timescales of a few minutes and the orbit of SMILE will enable such movements to be tracked for segments lasting many hours.SXI is led by the University of Leicester in the United Kingdom(UK)with collaborating organisations on hardware,software and science support within the UK,Europe,China and the United States. | S.Sembay A.L.Alme D.Agnolon T.Arnold A.Beardmore A.Belén Balado Margeli C.Bicknell C.Bouldin G.Branduardi-Raymont T.Crawford J.P.Breuer T.Buggey G.Butcher R.Canchal J.A.Carter A.Cheney Y.Collado-Vega H.Connor T.Crawford N.Eaton C.Feldman C.Forsyth T.Frantzen G.Galgóczi J.Garcia G.Y.Genov C.Gordillo H-P.Gröbelbauer M.Guedel Y.Guo M.Hailey D.Hall R.Hampson J.Hasiba O.Hetherington A.Holland S-Y.Hsieh M.W.J.Hubbard H.Jeszenszky M.Jones T.Kennedy K.Koch-Mehrin S.Kögl S.Krucker K.D.Kuntz C.Lakin G.Laky O.Lylund A.Martindale J.Miguel Mas Hesse R.Nakamura K.Oksavik N.Østgaard H.Ottacher R.Ottensamer C.Pagani S.Parsons P.Patel J.Pearson G.Peikert F.S.Porter T.Pouliantis B.H.Qureshi W.Raab G.Randal A.M.Read N.M.M.Roque M.E.Rostad C.Runciman S.Sachdev A.Samsonov M.Soman D.Sibeck S.Smit J.Søndergaard R.Speight S.Stavland M.Steller TianRan Sun J.Thornhill W.Thomas K.Ullaland B.Walsh D.Walton C.Wang S.Yang | 2024 | Earth and Planetary Physics2024,8,1: | 4 |

| 4 | 土壤酸度研究问题的新进展显示文摘本世纪五十年代中期重新发现了交换性铝,那时,对交换性铝的认识是简单的和一致的,但现在情况已不同了。当然,因为进行了更多的研究我们才逐步知道了一点铝在土壤中的行为,例如聚合物的形成、带羟基铝粘土矿物的层间化以及铅与土壤有机质的相互作用。今天看来,交换性铝的概念仍具有重大的现实意义,但是,它包括的只是土壤中铝的多种存在形式之一。本文讨论了自五十年代以来有关铝的研究结果,并加以评述。 | Grant W.Thomas 丁汉凤 | 1992 | 土壤学进展1992,20,4: | 1 |

| 9 | 一种用于连井地震勘探的新型压电传感器显示文摘我们已研制出一种高效压电传感器。在油井和其它井眼中。它既可以用作震源,也可用作地震检波器。该传感器的设计是新颖的,其结构是将一个圆柱形空心压电陶瓷材料紧紧地装在一个紧贴在外的钢管内表面上,此压电陶瓷柱的长度/半径比率相对较大,从而组成一个圆柱形压电陶瓷与金属材料弯曲机。这种压电圆柱形组合结构为传感器设计带来了许多灵活性,为用于井到间震源和检波器探头的研制带来很大便利。最近,应用两个相匹配的圆柱形弯曲机震源与检波器进行了野外实验测试,震源与检波器工作范围在500-5000Hz,这种圆柱形弯曲机震源具有非常好的波形重复性。 | W.Thomas Balogh 王风岐 | 1989 | 石油物探译丛1989,,5: | 0 |
| 10 | Expression of HBxAg in human chronic hepatitis,cirrhosis and primary hepatic carcinoma and its significance显示文摘The specimens of this study were obtained from 110 cases of chronic hepatitis,108cirrhosis and 110 primary hepatic carcinoma(PHC).Formalin-fixed and paraffin-embedded seetions were stained by ABC method forHBxAg,and by PAP method for HRsAg and HBcAgOf the 110 cases of chronic hepatitis,72(65.5%)were positive HBxAg in the liver cells,66(60%)were postitive in HBsAg and 35(31.8%)in HBcAg.Among the 108 eases of drrhosis,84(77.8%)revealed to be HBxAg positive in the liver cells,73(67.6%)were demonstrated to beHBsAg-positive and 18(16.7%)were shown to be HBcAg-positive.Among the 110 eases of pri-mary hepatic carcinoma,64(58.2%)showed HBxAg-positive reaction in cancerous tissues.Therates of positive HRsAg and HBcAg in tumor tissues were 15.5% and 10.9%,respectively.Six-ty-three(78.8%)of 80 cases of the non-cancerous hepatic tissues displayed HBxAg positivenessand the rates of positive HRsAg and HBcAg in the non-tumor tissues were 47(58.8%)and 21(2.6.3%),respectively.The above-mentioned results sugared that the detection rote of HBxAg inchronic hepatitis,cirrhosis and PHC was higher than that of HBsAg and HBcAg.This studydemonstrates a dose relationship between chronic hepatitis,cirrhosis,PHC and chronic persistentinfection of hepatitis B virus(HBV).Persistent chronic HBV infection plays an important role inthe pathogenesis of chronic hepatitis, cirrhosis and PHC.It is possible that the detection ofHBxAg with anti-HBx could be an additional new diagnostic marker for HBV infection.Howev-er,the role of HBxAg in the pathogenesis of chronic liver diseases needs to be furtherinvestigated. | 王文亮 W.Thomas London Mark A.Feitelson | 1992 | Journal of Medical Colleges of PLA(China)1992,7,2: | 0 |

| 13 | 氟橡胶的低温密封能力显示文摘通常弹性体密封件是在受压变形下工作的,它靠两个相对壳体的挤压提供压力。该密封压力随时间和温度而变,且随材料的物理性能的降低或缓慢的化学作用而逐渐下降。密封力保持率与胶料的应力松弛性能有关。应力松弛的结果将使压缩应力慢慢下降,当压缩力低于本系统的压力时就会产生泄漏。 | Donald D.Stevens Eric W.Thomas James H.Brown 高桂芝 | 1992 | 橡胶参考资料1992,,9: | 0 |
| 14 | 慢性肝炎和肝硬变内HBxAg分布并与HBsAg和 HBcAg的关系显示文摘作者所用110例慢性肝炎和108例肝硬变标本来自西京医院病理科.10%福尔马林固定,石蜡包埋,HE染色,检测HBxAg用ABC方法,检测HBsAg和HBcAg用PAP方法.在110例慢性肝炎中,72(65.5%)例在肝细胞内显示HBxAg阳性,66(60.0%)例HBsAg和35(31.8%)例HBcAg亦阳性.在108例肝硬变中.84(77.8%)例在肝细胞内显示HBxAg阳性,73(67.6%)例HBsAg和18(16.7%)例HBcAg亦阳性.HBxAg与HBsAg和HBcAg之间的关系:在72例HBxAg阳性的慢性肝炎中,56(77.8%)例伴有HBsAg或(和)HBcAg.在84例HBxAg阳性的肝硬变中,60(71.8%)例伴有HBsAg或(和)HBcAg.所有HBsAg或HBcAg阳性的病例,HBxAg也阳性.结果表明,HBxAg的表达和HBV感染有密切关系.HBxAg的检出率比HBsAg和HBcAg高,因此检测HBxAg可以作为判断HBV感染的指标之一.HBxAg在慢性肝炎或肝硬变的发病中可能起重要作用,但如何起作用有待进一步研究. | 王文亮 W.Thomas London Mark A.Feitelson | 1992 | 第四军医大学学报1992,13,4: | 0 |
