The age ［A］ of a geological sample can be estimated ［B］ from the ratio of radioactive to nonradioactive carbon present ［C］ in the object is examined ［D］.

这时，我们可以把-ED分词结构理解为一个省略句，即省去了"主语和be的变化形式"。

The age of a geological sample can be estimated from the ratio of radioactive to nonradioactive carbon present in the object is examined .

ED 分词用作状语时，跟-ING 分词作状语时一样，修饰主句的谓语动词，意义上相当于状语从句，表示时间，条件，原因，伴随状况等。

Polymarase Chain Reaction may be the better method of detecting M.tuberculosis than other methods and lead us to carry out a series of research on this problem. This thesis is composed of five parts:(1)systematic evaluation for the first time of the ability of five defferent PCR methods to detect M. tuberculosis;(2) using the endonuclease and southern blot by a radioactive and a nonradioactive labeled probe, to confirm the specificity of the PCR products and to analyse the sensitivity of detection by southern blot method using digoxigenin-labeled probe;(3) evaluation of acid-fast staining, bacterial culture and PCR for the detection of M. tuberculosis in sputum, pleural and peritoneal effusion samples;(4) The feasibility of PCR for detection of M tuberculosis on formalin-fixed paraffin embedded tissues;(5) 26 cases of sarcoidosis were retrospectively studiedwith PCR for M. tuberculosis and nontuberculosis Mycobacterium and the problems on histopatholoical diagnosis of sarcoidosis are discussed.

论文共分为五个部分，(1)首次系统地比较了五种不同引物序列的PCR检测结核杆菌方法的特异性和敏感性等情况；(2)利用限制性内切酶酶切分析和同位素及非同位素标记DNA探针进行Southern杂交的办法，分析PCR产物的序列与原设计是否相符及杂交检测PCR产物对提高检测结核杆菌敏感性的情况；(3)并对PCR用于快速检测临床标本中的结核杆菌进行了初步评价；(4)探讨了PCR用于检测石蜡包埋组织中结核杆菌的作用；(5)并利用PCR检测结核杆菌和非结核分枝杆菌的方法对26例原病理诊断为结节病的病例进行了PCR检测及组织病理学诊断的探讨。

多数情况下所有核电站废弃物都会存在核辐射数千年，要使这一部分废弃物不带有辐射又是不估计的，所以核废物必需用科技家们发明的一种窍门来储存处理。

Treatment incurred as a result of exposure to non-medical nuclear radiation and/or radioactive material.

治疗所造成的暴露在非医疗核辐射和/或放射性物质。

Of course, nuclear energy also creates problems, such as the radioactive waste from nuclear power plants.
