The process of lyophylisation carried out very carefully under strictly defined conditions does not in inself bring about the changes in the parameters of the ESR signal with g approximately equal to 2.00 observed in animal cells. The free radicals responsible for the ESR signal observed under usual experimental conditions, result from a contact of the lyophylised specimen with moisture at an optimum water content of about 10%.
在严格规定的条件下非常小心地进行的冻干过程本身并不会导致在动物细胞中观察到的g值约等于2.00的电子自旋共振（ESR）信号参数发生变化。在通常实验条件下观察到的导致ESR信号的自由基，是由冻干样品在约10%的最佳含水量下与水分接触产生的。
