To solve these problems, we must make it clear that: why helium could state in these materials; what disadvantages whill bring to the performance of these materials by these processes; what the influence factors of these processes and how we could control them. These problemes were came up from metaphase of 20th century, and that from 1970s, with the design of fusion reactor and the research development of its materials, we make it sure that these problems must be solved firstly.

为了解决这些问题就需要搞清楚：氦在材料中为什么能够滞留，在什么情况下会聚集、扩散及释放出来；这些过程对材料性能有什么害处；它受什么因素影响以及如何控制它等等。20世纪中期这些问题就已经被提出来，而从70年代开始，随着聚变反应堆的设计和聚变堆材料研究的进展，更加明确它是一个需要解决的难题。

Objective The origin and the nature of the Hodgkin and Reed-Sternberg cell of Hodgkins lymphoma has been attracting a lot of medical researchers engaged in studying it,for its character by scattered large atypical cells residing in a complex admixture of inflammatory cells.Great improvement has been made since a new method of isolation of single H/RS cells from a frozen section had been set up by KUppers in 1994,and many studies have approved of the B-cell derivation of H/RS cell.lt has been reported that H/R-S cells might partly be originated from B-cell in our research before,but at the same time,we also found that only 18.8% of H/RS cells express CD20,31.3% of immunoglobulin heavy chain rearrangement have been revealed.

目的 霍奇金淋巴瘤(Hodgkins lymphoma，HL)由于它的恶性肿瘤细胞—H／RS细胞一般只占肿瘤组织的极少部分(不到1％)，且散在分布在背景细胞间，因此对于H／RS细胞的来源和性质研究一直是人们探索的目标。1994年德国科隆大学Kūppers等发展了一种从冰冻组织切片上用显微操作仪挑取单个H／RS细胞的显微切割方法进行H／RS细胞基因分析后，人们对H／RS细胞来源的研究有了突破性的进展，多数支持B细胞来源。
