This paper reviews a report about the first lot of rectifiers and thyristors, which were manufactured by NTD-Si (that is the stripeless silicon), with high voltage and high current 30-years ago.
评述了30年前第一批用中子嬗变掺杂硅单晶(即无条纹硅)制造高电压、大电流整流管和晶闸管的报道。
Discusses the relations of absolute monotone bases,absolute bases and absolute rearrange bases,and discusses the relations of absolute bases and unconditional bases.
讨论绝对单调基、绝对基和绝对重排基之间的关系,以及绝对基与无条件基的关系,证明了在实空间中,绝对基与1-无条件基是等价的,在复空间中则不然。
In addition, some properties of unconditional bases for Banach spaces is also given.

Through expounding on Jaques Derrida s differentiation of the "sovereignty" and the "unconditionality," the thesis explores Derrida s concept of "wholly other" and emphasizes that the understanding of this essential concept is the foundation of endorsement with a Derridean profession of faith or a pledge of allegiance.
文章通过阐发德里达对所谓"主权"和"无条件性"所作的区分,探讨了德里达的"整体性他者"观念,指出理解这一观念是赞同德里达的信仰表白的基础。
