- 方法 将Wistar大鼠 随机分为5组,除空白对照组外,其余4组均经免疫抑制处理(注射阿糖胞苷与60Co全身照射),皮下接种胃癌细胞 悬液,制成胃癌大鼠模型。Methods The Wistar rats were randomly divided into five groups. Except for normal control group, the other four groups were injected Arac and radiated with 60Co, then transplanted with BGC-823 gastric cancer cells to form gastric cancer rat models.
- 利用60Co辐射诱变,选育出一株正突变菌株R4-5-27,在同等发酵条件下,生物量达到10.25mg/L,铁含量7.43mg/g,总铁含量为76.16mg/L,比出发菌株提高了1.59倍。In the same measure , the biomass was 10.25 mg/L, iron content of the yeast cell was 7.43 mg/g.
- 针对ROSEM、代数迭代算法(ART)和卷积反投影算法(CBP),分别做了模拟实验和实际汽车CT检测以及集装箱CT检测实验,并分析比较了它们在60Co集装箱CT检测中的应用。Performances of ROSEM,CBP and ART are analyzed on both Sheep-Logan digital phantom and the ~(60)Co Container inspection system. ROSEM exceeds ART in both speed and image quality,but exhibits a slower speed than CBP.
- 介绍二级标准剂量学实验室(SSDL)参加国际原子能机构(IAEA)和世界卫生组织(WHO)组织的SSDL间TLD国际比对的目的和方法,并对60Co放疗水平国家二级剂量标准1989-2006的比对结果进行总结。We introduce the objective and methods of SSDL participating in TLD international intercomparision organized by IAEA/WHO, and summarize the intercomparision results of national secondary dosimetry standard for 60Co radiotherapy level in 1989-2006.
