放射性

Then the radiological toxicity of spallation products was studied by applying the concept of annual limit of intake.

采用年摄入量限值标准定义的放射性毒性，对散裂靶中散裂产物产生的放射性毒性进行研究分析。

Radioactivity such as that of strontium 90 causes health problems in people even at low levels.

像银－90的放射性，哪怕是较低水平的放射性，都会对人体的健康造成危害。

It summarizer the environmental monitoring activities carride out byin the USSR and some other countries after the accident .

本文介绍了苏联切尔诺贝利核电站事故的放射性核素释放和地面沉降特点，简述了事故后苏联和其他国家的环境监测活动并讨论了γ能谱技术在环境放射性监测中的重要性。

However, there also are problems with disposal of low level radioactive wastes and mill tailings

然而，还有一些涉及低放射性废物的处置和低放射性污水排放的问题。

On the basis of the theory concerning the sta- bility of the 〓—complexes it is expected that the linear ligands of 〓 may combine with the technetium and produce some stable complexes.

99m放射性药物在核医学领域内的应用，推动了锝配合物的研究，而锝配合物理论研究的进展又进一步指导〓-99m放射性药物的设计及合成。

In my study, the incidence of acute radiation tracheitis was 53.8% in CRT group, all of them were Ⅰor Ⅱgrade, it was obvious that conformal radiation technique was better and reduced the incidence of it.

本研究中，适形治疗组放射性气管炎的发生率为53.8%，且全部为Ⅰ、Ⅱ级，明显轻于其他两组，可见，适形治疗技术可以明显的降低急性放射性气管炎的发生。

The bacterial bioplastic coating argument is the strongest, as there have been cases in which ancient textiles have yielded radiocarbon dates much younger than other artifacts in the same sites—most notably in the instance of mummy 1770 in the British Museum, whose bones dated 800 to 1,000 years older, according to the radiocarbon tests, than the textile in which they were wrapped.

细菌性的&原生体覆盖物&的争论来得更激烈，已经有案例，就是古代纺织品的放射性碳年代测定比其他同样大小的史前器物的年代要晚得多——最值得注意的例子就是1770年陈列在大英博物馆的木乃伊，根据放射性碳年代测定，骨骼的年代为800至1000年之久，它们都被包裹着。

Surface heat fow q〓and heat generation A〓of Yunnan area are regressed, the linear regression correlation is: q〓=55.36+9.17A〓,wth regresion coefficient: r=0.7345 and reduced heat flow q〓=55.36mW/m〓. However, the q〓-A〓relationship can not explain the heat flow pattern of the area because this is a convergence area of several terrains with different geological structure and evolution history.

对云南部分有实测放射性生热率的钻孔的地表热流和放射性生热率进行线性回归，得到q＝55.36+9.17A，线性回归系数r＝0.7345，其q〓＝55.36mW/m〓，这一关系不足以揭示云南这一若干不同地质结构与演化历史地块汇聚的地区的热结构。

3 Patients were in the acutestage,〓FDG and 〓NH〓 PET showed brain stem infarction in 2 patients, while CT was normal. MRA of one of them showed right vertebral artery obstruction. One case showed focal infarction within the territory of the right middle cerebral artery 12 hours after stroke onset.〓NH〓 uptake was reduced in right frontoparietal lobe, putamen and part of thalamus, while hyperperfusion was observed in ipsilateral head of caudate nucleus and a portion of thalamus.

急性期3例，2例〓FDG和〓NH〓均示病灶位于右侧脑干为放射性缺损区，CT检查均未显示，1例MRA示右侧椎动脉阻塞：另1例〓FDG示病灶在右侧大脑中动脉区域，与12小时CT所示病灶范围相同，但12小时的〓NH〓示右侧额、顶叶，壳核和部分丘脑为放射性减低和缺损区，而同侧尾状核头部和部分丘脑为过度灌注；发病24小时〓FDG显示除〓NH〓所见缺损区外，右侧额、顶叶部分区域和右侧尾状核头部代谢异常增高，血流和代谢有不一致处。

Label aFGF with 〓Ⅰ and deposits with TCA, and measure the total radiation of the blood or serum after the local burned wound was given to 〓Ⅰ-aFGF in rabbit and record the concentration-tine grapy and relative parameters of pharmacokinetics.

五、〓Ⅰ-标记aFGF结合酸沉淀的方法，观察家兔皮肤烧创伤面用药后血浆或血清总放射性，TcA可沉淀放射性〓Ⅰ-aFGF浓度一时间变化图形和有关的药代动力学参数。

Chrysanthemum of 10 thousand birthday is lax to edaphic requirement, with the arenaceous qualitative loam with fecund, good drainage had better.

万寿菊对土壤要求不严，以肥沃。排水良好的砂质壤土为好。

He unstepped the mast and furled the sail and tied it.

他拔下桅杆，把帆卷起，系住。
