制备这种MgB 2 超导材料的方法,其特征在于,将Mg粉,B粉,C纳米粉,SiC纳米粉按照摩尔比(0.8-0.975)∶(1.8-1.95)∶(0.010-0.15)∶(0.010-0.15)配制并混合均匀,装入铁管或铁铜复合管中密封后,按顺序先后进行旋锻、拉拔、轧制,得到含C和SiC纳米粉的MgB 2 超导线材;或者将混合均匀的原料粉用压片机进行压片,得到含C和SiC纳米粉的MgB 2 超导块材;将得到的线带材或块材放置真空炉中,抽真空后充入氩气,在600℃-1200℃保温0.2-3小时,最终得到含有C纳米粉和SiC纳米粉的MgB 2 超导材料。

Group E = atmospheres containing metal dust including aluminum, magnesium, their commercial alloys, and other metals of similar hazardous characteristics; Group F = atmospheres containing carbon black, coal or coke dust; Group G = atmospheres containing flour, starch, or grain dust.

组E =大气中含有金属粉尘,包括铝,镁,它们的合金,具有类似危险特性的其他金属;组F =大气中含有炭黑,煤或焦炭粉尘;组G =大气中含有面粉,淀粉,或谷物粉尘。

According to the domain organization, the GGDEF-EAL containing proteins (pfam database, version 17.0) were classified into A and B types. Six hundreds and five of the 621 proteins were in A type, which was also found in the ancient bacteria Aquifex aeolicus VF5 suggesting that this is the ancestor of the GGDEF-EAL proteins. Phylogenetic analysis of GGDEF- and EAL- containing proteins in the genome of V. vulnificus YJ016 revealed that GGDEF-EAL proteins were clustered. Comparative analysis of domain organization of the clads in the EAL tree allowed identification of several duplication events. The results indicated that most of the GGDEF- and EAL- containing proteins arised by gene duplication.

根据pfam资料库(Version 17.0),我们整理同时拥有GGDEF和EAL功能性区域的蛋白质,这些蛋白质可以被区分成两种型态,在总数621个GGDEF-EAL中有高达606个是A型态,而且它在古老的细菌Aquifex aeolicus VF5的基因体中也能找到,因此我们推测它可能是GGDEF-EAL的袓先,藉由分析创伤弧菌中所包含之GGDEF和EAL的演化关系,大部份的GGDEF-EAL会群聚在树型相近的位置,进一步比较在EAL树型上有邻近关系的蛋白质序列,根据他们的长度、与所包含的功能区域,我们找到了一些重制的演化痕迹,这样的结果指出,目前看到大多数的GGDEF 和EAL可能都是经过重制产生。
