回旋加速器

The developments of cyclotrons are outlined.

随着回旋加速器本身的发展，其应用日益广泛。

Because Washington University's Mallinckrodt Institute of Radiology and several other universities have their own small cyclotrons, devices that can produce radionuclides, Dr. Welch plans to establish a production network among these universities to meet the investigators' needs.

因为华盛顿大学的Mallinckrodt放射学研究所与其他几个大学拥有自己的小型回旋加速器，能够生产放射性核素的设施，Welch博士计划在这些大学建立一个生产网络以满足研究人员的需求。

Magnet design and modeling is a crucial task in the design of cyclotrons, which includes iterative processes from an initial model.

磁铁设计对于等时性回旋加速器极为关键。

Designs of two high intensity cyclotrons are studied in these two chapters, one is 50MeV-5mA H〓 superconducting Sector Focused Cyclotron, the other is 17MeV-2mA H〓 Sector Focused Cyclotron.

第三章首先简单介绍了用于扇聚焦回旋加速器的各种注入方法以及在轴向注入时所采用的不同种类的静电偏转镜。

The first specialties cyclotron used in tumor therapy is empoldered by IBA and Harvard University, and in 1998 started to use at MGH.

而第一台专门用于治疗的回旋加速器是由比利时的IBA公司和哈佛大学联合开发的，1998年开始在美国麻省总医院启用。

Nuclides with surplus positive charge are easily made in a cyclotron and are widely generated for medical use.

具有剩余阳电荷的核素容易地在一个回旋加速器中被制造出来并且被广泛制造用于医学用途。

The absorption and distribution of chromium were studied in ryeusing nutrient culture technique and pot experiment.

采用不同浓度K2CrO4(0，0.4，0.8和1.2 mmol/L)的Hoagland营养液处理黑麦幼苗，测定铬在黑麦体内的亚细胞分布、铬化学形态及不同部位的积累。

By analyzing theory foundation of mathematical morphology in the digital image processing, researching morphology arithmetic of the binary Image, discussing two basic forms for the least structure element: dilation and erosion.

通过分析数学形态学在图像中的理论基础，研究二值图像的形态分析算法，探讨最小结构元素的两种基本形态：膨胀和腐蚀；分析了数学形态学复杂算法的基本原理，把数学形态学的部分并行处理理念引入到家实际应用中。
