查询词典 tracing point

Distinguish by using a radioactive isotope or an isotope of unusual mass for tracing through chemical reactions.

用放射性同位素或不寻常质量的同位素使元素或原子显示运动踪迹。

As a tracing agent , the radioactive isotope has a high sensitivity for detection.

放射性同位素作为示踪剂，其检测灵敏度高，在染色和盐类示踪剂不能奏效的情况下，放射性示踪剂都能得到成功。

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。
