放射的

We have shown that it is possible to create a radioactivity characterized by the emission of positive or negative electrons in boron and magnesium, by bombardment with alpha rays.

我们已经展示了人工放射现象的可能性，这种放射现象的特征是用以射线轰击用咄硼和镁中的正电子或负电子。

Therefore, it is very necessary to offer the latest achievement and progress trends in ecological studies on living radiolarians to research communities, with a view to making our research on radiolarian keep pace with the world and offering more proxies of paleoenvironment and paleoceanography.

因此，有必要向我国学术界提供放射虫现代生态学的研究成果及最新发展趋势，促使我国放射虫的研究与国际接轨，以提供更多的古海洋、古环境替代性指标。

Allowing the passage of x - rays or other radiation ;not radiopaque.

射线可通过的允许X射线或其它放射通过的；非放射不透明的

This paper introduces the application of integrated geophysical investigation, including high precision magnetic, multielectrode method and GPR , to systematically detect a radioactive material source sealed in lead container stored in a chamber buried underground,which has been missed.

采用综合地球物理勘查技术，包括高精度磁测、高密度电法和地质雷达对某处遗留于地下的铅封放射源进行了系统探查，对所获得的各类异常数据进行了分析处理，并指出了放射源所在的具体空间位置。

Cases 1-5 who presented with spastic paraparesis and other prominent upper motor neurone signs showed high signal on T1-weighted images in the centrum semiovale, corona radiata and posterior limb of the internal capsule which corresponded to the large myelinated fibres of the corticospinal tract Fig.

病例1~5患者表现为下肢痉挛性轻瘫和其他一些明显的上运动神经元症状体征，在T1像上于半卵圆中心、放射冠、内囊后肢处的皮质脊髓束大有髓纤维走行区均可见高信号病灶（图1），在T2、PdWI像上也可见自放射冠延伸至大脑脚的高信号病灶。

The ESTRO Radiotherapy Information Centre is an open access resource with sections for patients, health professionals, journalists and researchers as well as data on cancer and its treatment across Europe.

欧洲放射治疗肿瘤学会放射治疗的信息中心是一个为患者，医务工作者，新闻工作者和研究人员以及对治疗癌症和整个欧洲的数据节开放获取资源。

When conventional radiotherapy of nasopharyngeal carcinoma is practiced with the facio-neck field and inferior-neck-supraclavicular field by the half-beam technique, it is confirmed that the dose-overlap region at the match-plane is smaller than the whole-beam technique.

背景 近年来放射治疗剂量学研究表明，鼻咽癌应用面颈联合野与下颈切线野放射治疗时，与全束照射技术相比，半束照射技术的照射野衔接处剂量重叠区较小，理论上可能降低放射性神经损伤的发生率。

Some scholars have suggested in recent esophageal cancer in vitro three-field irradiation method, subparagraph hyperfractionated radiotherapy, and the introduction of 60 Co, 137Cs, 192Yb esophageal cavity Brachytherapy to reduce lung tissue and spinal cord suffered while reducing the radiation dose radiation injury, increased radiation therapy.

近有学者建议采用食管癌体外三野照射法、超分割分段放疗，以及采用60Co、137Cs、192Yb食管腔内近距离放疗，以减少肺组织及脊髓所受的放射剂量而减轻放射损伤，提高放疗的疗效。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
