In order to achieve the required angular resolution, a sophisticated tracking detection system was established to reconstruct the track of each incident particle, as well as each scatted particle. The upstream detection system consisted of two plastic scintillators (T1 and T2) and two low-pressure multiwire proportional chambers .

He是结构性质比较典型的丰中子核，也是RIBLL可以产生的束流强度较大的放射性核素。2001年3月，我们利用兰州近代物理研究所的放射性次级束流线装置提供的25MeV/n的〓He轰击〓Be和〓Li靶，进行了〓He+〓Be的准弹性散射的研究。

The fiber film material with the radioactive nuclide mark is covered at a tumour part or a lesion tissue part after resection, thereby effectively killing the residual tumour cells, and playing roles in stanching, healing wound and preventing adhesion and so on.

将上述放射性核素标记的纤维膜材料包裹在肿瘤或手术切除后的病变组织部位，对残余的肿瘤细胞进行有效灭杀，可以发挥纤维膜的止血、促进伤口愈合以及防粘连等功能。

radionuclide bone imaging is of importance in diagnosing multiple myeloma,and is superiored to radiography in detecting lesions in ribs and sternums.

核素骨显像对mm的辅助诊断具有重要的意义，尤其是肋骨及胸骨病灶，其检出率优于x线检查。

These showed that there was an accumulation of agent in strangulated ischemic bowel segment in strangulated loop group and mesenteric venous occlusion group.All results suggest that radionuclide visualization with SPECT could be a valuable method for early diagnosis of acute intestinal strangulation of strangulated loop type and mesenteric venous occlusion type.

本实验结果提示：闭袢型和静脉阻塞型绞窄缺血肠段早期有显像剂的聚集；SPECT的核素显像技术可作为早期诊断闭袢型和肠系膜静脉阻塞型肠梗阻有价值的辅助手段。

Law of cell multiplication 3）relationship between molecular structure and function.

放射性核素示踪技术的基本类型及应用：1）研究物质代谢的体内与转化的规律；2）研究细胞增殖的规律；3）研究物质分子结构与功能关系

The high rotten coal (including the anthracite and meager coal ) radioactive level is relatively low,( 238U: 29.1Bq/kg , 232Th: 25.9Bq/kg , 226Ra: 37.5Bq/kg), obviously lower than the radioactive levels of the brown coal and bituminous coal, and fluctuating range little relatively stable until Lincang uranium germanium colliery HeKai Tian little dragon's pool power plant make , investigate than right far correctly, prove natural radioactive nuclide (238U , 232Th , 226Ra ) than activity transformation in the course of utilizing and give locality radiate influence that environment bring.

高变质煤放射性水平相对较低，（238U：29.1Bq/kg、232Th：25.9Bq/kg、226Ra：37.5Bq/kg），明显低于褐煤和烟煤的放射性水平，且波动范围较小、相对稳定通过对临沧铀锗煤矿田和开远小龙潭电厂作出调查比对，说明了天然放射性核素（238U、232Th、226Ra）比活度在利用过程中的转移以及给当地放射环境带来的影响。

In order to investigate the effect of minior actinide data on integral parameter, the accelerator-driven minior actinide benchmark system was selected in this work.

为了确定加速器驱动系统中少錒系核素的核数据的不确定性对此系统中积分参数的影响，选择一铅－铋冷却次临界系统来进行分析，选择不同的微观评价库，CENDL-3.0，JENDL-3.2及ENDF/B-VI。

The designed formulae for solidification of actinide s were given, and the properties of the waste form, like physical properties, durability properties and irradiation properties, were evaluated.

研究了富钙钛锆石型和富烧绿石型两种人造岩石固化体包容锕系核素的配方设计和固化产品的鉴定评价，包括物理性能、抗浸出性能和耐辐照性能。

The nuclide chart involves electron, positron, antiproton, antineutron, photon to exhibit the symmetry of mass and charge ideally.

该核素图将电子、正电子、反质子、反中子和光子收录在内，完美地表现了质量和电荷的对称性。

There are no influence on hybridization of conjugation with chelators and radiolabeling with gamma or bata emitting radionuclides.

耦联外源性螯合基团及标记不同种类的核素，对MORF的分子杂交活性无影响。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
