of后面加数字,求问“of”在本句中的用法
The predator-prey BMFs of HCH in ringed seals of 20 and in beluga whales of 50 exceed the BMFs of PCB 180 in those animals.
其中:
BMF是生物放大因子(是一个数字)
HCH和PCB 180是两种有毒化学物质
ringed seals是环海豹,beluga whales是白鲸
问题为:ringed seals of 20和beluga whales of 50 中的of,后面加数字代表什么意思?
of后面加数字,求问“of”在本句中的用法The predator-prey BMFs of HCH in ringed seals of 20 and in beluga whales of 50 exceed the BMFs of PCB 180 in those animals. 其中:BMF是生物放大因子(是一个数字)HCH和PCB 180是两
这里的【ringed seals of 20】即指环海豹HCH生物放大因子数值为20
【beluga whales of 50】即指白鲸HCH生物放大因子数值为50
而这两个HCH生物放大因子数值均超过了环海豹和白鲸各自对应的PCB 180生物放大因子数值
(生物放大因子:HCH>PCB 180)
