So, you know, I could separate radioactive isotopes.

那我就可以分离放射性同位素了。

The Ins stimulated reversible phosphorylatiome modification of proteome in neuron maybe overall and dynamically analyed,so as to find corresponding protein difference, and its preliminary qualitative analysis may be done by isotope labeling,dielectrophoresis,and radioautography,combining with bioinformatics technology.

采用同位素标记、双向电泳、放射自显影结合生物信息技术可对Ins刺激神经元中的蛋白质可逆磷酸化修饰进行较为全面、动态的分析，寻找出相应的差异蛋白，并可进行初步的定性分析。

Polyethylene glycol (MW6000 35%)-Ca〓(40mmol/l) system was applied to research on the fusion of nuclei and anucleated protoplasts which were deactivated by ultraviolet rays. The fusion process was verified by -dCTP radioisotope tracing with radioautography.

选择PEG6000促融，40mmol/1Ca〓进行了K氏酵母细胞核与His酵母经紫外线灭活的无核原生质体融合的研究，利用放射性同位素dCTP的示踪结合放射自显影技术，对融合进行检测，证实了融合的确实发生。

The scientific process of radiocarbon dating found that the village is about four thousand six hundred years old.

碳的同位素测时间的科学处理，发现村子有4600年了。

This approach seemed to work: radiocarbon dating of Taino posts has shown that they were in place for hundreds of years.

从考古证据看，这一推论应该是正确的：放射性同位素测定表明，那里的柱子已在原位牢牢竖立了好几百年，而更重要的是，那些木桩的树皮还好好的。

Accelerators are also used for radioisotope production, cancer therapy, Biological sterilization, and one form of radiocarbon dating.

加速器也用于制造放射性同位素、治疗癌症、生物消毒及放射性碳定年。

According to the technologies it takes, the enzyme activity detecting approaches could be divided into spectrophotometric and radiochemical assays.

根据使用的手段可分为放射性同位素标记法和分光光度法。

The radiochemical separation procedure of 132Ⅰ was designed on the basis of half-lives of iodine and tellurium isotopes in mixed fission products.

依据混合裂变产物中碘及其母体啼的同位素的半衰期设计分离132Ⅰ的流程。

Radiogenic argon (40Arr) is widely applied to isotope chronology and gas and source rock correlation.

稀有气体是天然气中指示其地球化学特征的重要组分，放射成因氩的年代积累效应广泛应用于同位素定年和天然气的气源对比。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。

Galvanizes steel pallet is mainly export which suits standard packing of European Union, the North America. galvanizes steel pallet is suitable to heavy rack. Pallet surface can design plate type, corrugated and the gap form, satisfies the different requirements.

镀锌钢托盘多用于出口，替代木托盘，免薰蒸，符合欧盟、北美各国对出口货物包装材料的法令要求；喷涂钢托盘适用于重载上货架之用，托盘表面根据需要制作成平板状、波纹状及间隔形式，满足不同的使用要求。
