求翻译:对同一浓度下的Zn2+连续测定10次,求得相对标准偏差为2.518%,做回收实验,测得回收率在98.60% ~101.35%之间。是什么意思?

Continuous Determination of 10 times under the same concentration of Zn2 +, the obtained relative standard deviation of 2.518%, do the recovery experiment, the measured recovery rate of between 98.60% ~ 101.35%.

In the same concentration of 2+ consecutive Zn measured 10 times, compared to the standard deviation of a 2.518 % recycling, do experiments, recovery rate measured at 98.60 % to 101.35 %.

Determines continuously to under identical density Zn2+ 10 times, obtains the relatively standard deviation is 2.518%, does the recycling experiment, obtains the returns-ratio between 98.60% ~101.35%.

Zn2+ determination of 10 times in a row to the same concentration, seeking the relative standard deviation is 2.518%, doing recovery experiments, the measured recovery in between 98.60%~101.35%.
