放射性

Waste minimization is one of the principles of radioactive waste management.

1引言废物最少化是国际原子能机构确定的放射性废物管理的原则之一。

Such an observation can be best explained if Re and 187Os are internally decoupled within molybdenite grains.

这是因为Re和187Os在辉钼矿亚晶粒范围内出现了失耦现象，也就是由于放射性成因187Os的迁移使Re和187Os在空间上不再保持连接。

A formula for non-dimensional synthetic electronegativity was obtained by multiple regression analysis. The correlation coefficient (R=0.9844) and test of significance Sig.

采用回归分析法，对周期表中除零族、氢及放射性元素之外的77种元素的Pauling电负性X(下标 P进行回归分析，得到了一个无量纲的综合性的电负性计算公式，相关系数(R=0.9844)和回归方程F检验的显著性水平Sig。

Methods Comparative study were maded in 12 cases of early radiation myelitis with hyperbaric oxygen treatment and 10 cases with routine treament.

方法采用高压氧治疗放射性脊髓炎12例，与采用常规方法治疗的10例患者对照研究。

Hyperbaric oxygen treatment is one of the effctive treatment mathods for the early radiation myelitis.

结论高压氧治疗早期放射性脊髓炎是有效的治疗方法之一。

This method of drug delivery involves immobilization of drug or radionuclide in biocompatible magnetic nano- or microspheres.

这种药物的运输方法涉及在生物相容的磁性纳米或微米球上固定药物或放射性核素。

The evaluation of radiationinduced acute dermatitis was done according to CTC.V2.0 proposed by NCI.

根据NCI制定的CTC.V2.0急性放射性皮肤损伤的分级标准进行临床评价。

The concentration of neptunium and plutonium is extremely low in environmental samples.

核设施的运行，不可避免有放射性物质弥散到环境中。

Since 1980s, ICP-MS has been used overseas for the determination of uranium, thorium, neptunium, and plutonium in environmental samples. ICP-MS is one of the most suitable analysis techniques for the measurement of the long-lived radionuclides.

自八十年代以来，国外对ICP-MS测量环境样品中的铀、钍、镎和钚的研究表明，ICP-MS在测量长寿命放射性核素方面是最有发展前景的测量技术之一。

In order to provide a suitable 237Np reference solution for nuclear fuel reprocessing and environmental science, a radioactivity reference solution of neptunium-237 in 0.5 mol/L HNO3 is investigated. It is prepared by dissolution of a neptunium oxide stock from plant.

为了给乏燃料后处理工艺和环境科学研究提供合适的237Np标准溶液，研制了以0.5mol/L HNO3为介质的镎－237放射性活度标准溶液。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.

扫描电镜观察多杀性巴氏杆菌细菌幽灵和菌落形成单位评价遗传灭活率。
