The answer is that this bacterium has fixed within it a chain of about 20 magnetic crystals that are each between 35 and 120 nanometers in diameter
答案是这些细菌体内固定有一串约20个磁性晶体形成的链状构造，每个晶体大小在35 ~ 120奈米之间。
From the analysis of the microstructure of the modified epf30r , it indicated that the crystallinity , crystalline size , and the dimension of the filler particles of . the ppbc3b were all inferior to the epf30r ' s , which also verified the effect of the nucleator - dicpk
对改性epf30r的微观结构分析结果表明ppbc3b的结晶度、晶体大小、所用填充粒子大小都要低于epf30r及相关材料，同时证实了成核剂dicpk的成核作用。
