To create a mere three atoms of element 118 , the scientists spent two months bombarding the californium target with 30 billion billion calcium ions 为了创造这微不足道的3个原子，科学家花费了2个月时间，用30万亿亿个钙离子来轰击锎离子。

At the first start up of a new reactor , primary source rods consisted of californium - 252 are inserted into the reactor to produce sufficient neutrons to initiate the first fission 反应堆在首次启动时，会放入含有- 252 cf - 252的一次中子源棒，以提供足够数量的中子进行初次核裂变。

The blastn results show that gyn - 15 is closely related to a symbiont of anemones , s . californium , and the free - living strain , gymnodinium varians . sequence comparison show that the similarities among each part of the sequences from these three strains are all above 99 % . phylogenetic reconstruction with neighbor - joining ( nj ) method using sequences of variable regions ( v1 + v2 + v3 ) of ssu rdna indicated that gyn - 15 , s . californium and g . varians form a new clade with 100 % bootstrap support 以ssurdna序列中的三个可变区( vz + vz + v3 )和邻接法困eighbor一joiningmethod ， nj法)构建共生甲藻属的系统进化树表明， gyn一巧与5 . cal扣rnium和g . varian :在共生甲藻属内构成一个独立的、自检支持百分率为100 %的子类群( clade ) ，根据这些结果可将gyn一巧初步鉴定为属于共生甲藻属。
