介绍了一种新的用于g因子值的标定和电子自旋浓度测定的标准样品——磷掺杂硅的制备方法及其优点,并以粉末催化剂[Ni~(3+)(en)_2Cl)2]Y分子筛为例,介绍如何用该标准样品来测定固体催化剂的电子自旋浓度及二次积分的计算方法。 A new method for the preparation of phosphorus - doped silicon, a standard sample for the calibration of g - factor values ​​and determination of electron spin concentration, is introduced. The advantages and disadvantages of the powder catalyst [Ni ~ (3 +) (en) ) 2] Y zeolite as an example, how to use the standard sample to determine the solid catalyst electron spin concentration and calculation of the second integral method.
