 In the middle of 1980’s,an effective procedure for￣(10)Be measurement in loess by AMShas been established.Some important geochemistry behaviors such as good preservation of“Be in loess strata have been observed,showing obviously that the investigation on￣(10)Be inloess would be very significant.A total of more than 600 samples from the upper 0.4～138m of the Luochuan section was analysed for￣(10)Be concentrations and an isotopic curve ofcontinental deposition since 2.5 Ma has been established. Relative increase... In the middle of 1980’s,an effective procedure for￣(10)Be measurement in loess by AMShas been established.Some important geochemistry behaviors such as good preservation of“Be in loess strata have been observed,showing obviously that the investigation on￣(10)Be inloess would be very significant.A total of more than 600 samples from the upper 0.4～138m of the Luochuan section was analysed for￣(10)Be concentrations and an isotopic curve ofcontinental deposition since 2.5 Ma has been established. Relative increase of 20～25% of￣(10)Be concentration within 20～30ka duration are observed in the vicinity of the geomagneticreversals.The linearity of relationship between accumulation rate and￣(10)Be flux of loess isalso astonishingly good.It reveals a new way for the dating of loess strata. Both the eventof Raisbeck peak at 35000 a BP and￣(10)Be/￣(26)Al ratio have been studied,which are expectedto be new dating methods for loess strata。 Based on￣(10)Be susceptibility model with a newconcept of magnetic material flux,pedogenic ferromagnetic material flux in Chinese loesshave been estimated quantitatively and average paleoraiiifall values in Luochuan regionhave been calculated.The concentrations of in situ cosmogenic￣(10)Be in quartz from loesshave been measured accurately and the erosion rates of the source regions have also been calculated.  ８０年代中期，中国和瑞士科技工作者开始联合进行黄土￣（１０）Ｂｅ研究。建立了黄土￣（１０）ＢｅＡＭＳ测量的理想流程，发现了￣（１０）Ｂｅ在黄土地层良好保存性等重要地球化学行为特征，确认了黄土￣（１０）Ｂｅ研究具有重要意义。对洛川黄土剖面０．４～１３８ｍ段６００多个样品进行了￣（１０）Ｂｅ测定，建立了２．５Ｍａ以来大陆堆积物同位素记录曲线。地磁极性倒转期间，￣（１０）Ｂｅ浓度平均增高２０～２５％、持续２０～３０ｋａ。洛川、西峰黄土剖面￣（１０）Ｂｅ变化与深海沉积物δ￣（１８）Ｏ变化之间均存在极好相关性，据此建立了７５万年以来黄土地层相对￣（１０）Ｂｅ时标；黄土堆积速率与各时期￣（１０）Ｂｅ沉降通量之间亦存在良好的线性相关关系，据此可望建立￣（１０）Ｂｅ绝对时标。探讨了Ｒａｉｓｂｅｃｋ峰事件、￣（１０）Ｂｅ／￣（２６）Ａｌ比值等在黄土地层定年中的应用前景和途径。引入物理意义明确的“磁性物质通量”概念，建立了￣（１０）Ｂｅ—磁化率模型，定量估算出磁化率中降尘和成壤两组分相对贡献，求得洛川区域Ｓ＿０、Ｌ＿１、Ｓ＿１三时期年均降水量。精确测定了黄土石英中“就地”成因￣（１０）Ｂｅ含量，获得不同时期黄土源区侵蚀速率。  The ship may be threatened greatly by the electromagnetic pulse bomb(EPB).The susceptibility model is set up through the analysis of the especial killing effect of the EPB according to the killing characteristics of the EPB and the carrier point of falling distribution.The damage model is established according to the ship characteristics of protection against the electromagnetism.Based on that,the evaluation model of the ship survivability under the attack of the EPB is derived from.A conclusion...
