放射性

The air survey is specially superior in the regional environmental radioactivity survey, which is recommended by IAEA.

在区域环境放射性测量中，航测具有特殊的优势，是IAEA推荐的手段。

It's just radioactive enough for us to track the air moving through your lungs.

其放射性足以使我们能够追踪在你肺部的空气运动

The contents of Riboncules acid, 5 -hydroxyptamine (5-HT), Cyclic adenosine monophosphate , Cyclic guanosine monophosphate in milk; and the activites of Alkine phosphatese , lactic dehydrogemase in serum were determined by Chromometry and radioimmunoassay.

采用比色法和放射性免疫法测定了西农莎能奶山羊乳中RNA，S-HT，CAMP，CGMP和血清中LDH，AKP的含量为：0.432，0.408，0.405，0.473，0.194，0.405。

The crystal-chemical properties and the genesis of the allanite have been disscussed, in addition, the radioative decay of Th and U and the oxidation cause rare-earth elements to be released from its lattice to d...

认为本区的褐帘石是部分变生的。变生的机理是因为其晶格中含放射性元素U，Th高，且这与褐帘石的选矿性能有重要关系。

Atomic number Z = 25, atomic weight of 54938, the chemical symbol Mn, only the F there is a stable isotope, radioactive short-lived, there are three kinds of allotrope α,β,γ.

原子序数Z＝25，原子量54938，化学符号为Mn，只F有一种稳定同位素，放射性的寿命很短，有三种同素异形体α、β、γ。

Objective To investigate the effectiveness of compound aloes in the treatment of radiodermatitis.

目的 避免或减轻放射性皮炎症状。

Methods Sixty patients with radiodermatitis were randomly divided into observation group （receiving treatment of compound aloes） and control groups.

将120例放射性皮炎患者随机分为两组各60例，观察组采用自制复方芦荟制剂治疗，对照组用依剂复治疗。

The radiation of alpha particles during radioactive decay.

在放射性衰变的历程中放出α粒子的辐射。

Radioactive series: Any of four sets of unstable heavy atomic nuclei that undergo a series of alpha decay and beta decay until a stable nucleus is achieved.

放射性系：四组不稳定的重原子核，通过一系列α衰变和β衰变直至达到稳定的核为止。

Radioisotope per second to launch tens of thousands of alpha particles, each alpha particle in its within a very short trip can produce thousands of positively charged ions, that is, with the oxygen ions and a layer of intensive electronic clouds.

放射性同位素每秒钟要发射上万个α粒子，每个α粒子在其很短的行程内可产生上千个离子，即带正电的氧离子及一层密集的电子云层。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
