radioisotopes 中文意思是什麼

radioisotopes 解釋
放射性同位素
  1. Today many radioisotopes are produced using the particle accelerator called a cyclotron.

    今天許多放射性同位素是用被稱為回旋加速器的粒子加速器來製造的。
  2. All radioisotopes are prepared in this way, or by other methods of remote control.

    所有的放射性同位素都是用這種方法或其它遙控法制備的。
  3. Tgs method can determine quantitatively with high accuracy transuranic nuclides in heterogeneously distributed media with medium - and high - density, and is thus widely used to assay the location and quantity of selected radioisotopes in scraps and wastes within sealed containers

    它是專用於準確定量測量中、高密度非均勻分佈介質中的放射性核素及其含量，是核設施中可回收物以及核廢物測量分析的主要方法之一。
  4. The signal provided by the probe is a measure of the degree of hybridization. traditional dna probes are labeled with radioisotopes i. e. 32p, i25i, 3h or 35s

    傳統的dna分子雜交採用的是放射性標記的檢測方法，這種方法雖然靈敏度高，但存在放射性物質對人體及環境的危害。
  5. With advanced imaging and computing technologies, a three dimensional picture or animation can be generated to facilitate the diagnostic treatment if radioisotopes are injected or ingested into the patient

    運用現時先進的造影技術及電腦科技，只要我們將放射性同位素注入或進食入病人體內，就可以產生立體或動態的影像，從而研究病人的情況。
  6. Scientists already know the ages of the mare flows at the apollo sites from analyzing the radioisotopes in the rock samples, so they can estimate the ages of other flows by comparing their crater densities with those of the landing - site flows

    科學家分析巖石樣本中的放射性同位素，已經知道阿波羅登陸點的月海巖流年齡；因此將其他巖流的隕石坑密度與登陸點巖流的隕石坑密度相比，科學家便能估計其他巖流的年代。
  7. In addition, researchers have shown that low - cost laser accelerators are suitable for many of the same applications as conventional accelerators, such as producing short - lived radioisotopes used in medical diagnostics and generating neutron and positron beams for studies of materials

    此外，研究人員也證明，在許多應用上，廉價的雷射加速器都跟傳統加速器有同樣的功用，例如用來產生醫學診斷用的短生命期放射性同位素，或製造檢測物質用的中子與正子束。
  8. Most of earth ' s internal heat is generated by four long - lived radioisotopes ? potassium 40, thorium 232, uranium 235 and uranium 238 ? that release energy over billions of years as they decay into stable isotopes

    地球內部的熱能主要來自半衰期較長的四種放射性同位素鉀40 、釷232 、鈾235與鈾238 ，它們在幾十億年來逐漸衰變成穩定的同位素，同時釋放能量。
  9. So far, tgs is already a matured technology abroad with various types of tgs setups for determining radioisotopes in the samples with medium - and high - density heterogeneous drummed scraps and wastes

    到目前為止，國外tgs技術已基本成熟，而且已研製生產出各種類型的tgs儀器，成功應用於中、高密度非均勻樣品放射性核素及其含量的準確測量分析。
  10. The technique, which borrows from fusion energy research, takes advantage of the fact that 99. 9 percent of the radioisotopes in the waste are heavy elements, says company head john r

    該公司的老闆吉爾蘭說，核廢料中99 . 9 %以上的放射性同位素是重元素，他們的技術就是利用這個事實，而靈感是從核融合研究借來的。
