| 1 | 东格陵兰盆地晚二叠世缺氧事件:对北欧和北极潜在烃源岩的意义显示文摘在东格陵兰盆地,晚二叠Ravnefjeld组(FoldvikCreek群)海相沉积物属Wuchiapingian期(Stemmerik等,2001),遍布整个东格陵兰盆地的Ravnefjeld组由三套生物扰动粉砂岩夹两套薄层状泥页岩组成(Piasecki和Stemmerik,1991)。这些富含有机质的薄层沉积是易于生油的烃源岩,其平均总有机碳含量为4wt%,HI值为300~400mg/g TOC,属于Ⅱ型于酪根(Christiansen等,1993)。黄铁矿莓球的含量表明这种薄层的沉积条件为含硫底水,生物扰动单元代表半氧化-氧化条件(Nielsen和Shen2004),氧化还原敏感元素也指示了沉积环境。 | Jesper Kresten Nielsen Yanan She Jan Kresten Nielsen Nils - Martin Hanken Sten- Andreas Grundvag 吴峧歧(译) 邱燕(校对) | 2008 | 海洋地质2008，24，3： | 1 |
| 2 | 5-13 A Design of Current to Frequency Converter for Dose Monitoring in Heavy Ion Therapy显示文摘In order to make sure that the tumor is irradiated by a uniform and adequate dose and the surrounding tissues are damaged as little as possible,we need to monitor and measure the irradiation dose in real time.The dose monitoring probe of the beam intensity monitoring system in the deep-seated tumor therapy is an integral ionization chamber,its’output current signal is proportional to the beam intensity.The output signal of the ionization chamber is less than 1 A.In order to measure the weak current signal,a new current to frequency converter has been developed. | Wang Yanan She Qianshun Su Hong | 2016 | IMP & HIRFL Annual Report2016，，1： | 0 |
