能谱定量分析的结果里，K表示什么？

这个初级问题我来回答：K、L、M、N、O是原子中电子所处的壳层 ，K是最里层。基础知识！！

K是K Factor，好像是将X射线强度转换成重量百分比或物质的量百分比的一个参数。

Ratio Standard

A proportionality factor, known as the k factor is used to relate the characteristic X-ray intensities IA/IB in a thin sample to the actual concentrations in wt% in the form

CA/CB = KAB.IA/IB

where I = Intensity, and C = concentration.

K factors

The k-factor relates the intensity of two elements. Where more than two elements are to be analyzed, if all ratios are taken with respect to a single element (this is called the ratio standard element), these values can be regarded as elemental sensitivity factors, more usually known as k-factors.

The theoretical k factor value is determined using the X-ray line type (K series, L series, etc) for the ratio standard you select. For a given X-ray line, A, and ratio standard line, R, the k factor kAR is calculated as follows:

kAR = AA wR QB aR eR / AR wA QA aA eA

where A = atomic weight; w = fluorescent yield; Q = ionisation cross section; a = the fraction of the total line, e.g. Ka / (Ka +Kb ) for a Ka line, and e = the absorption due to the detector window at that line energy.

Once k factors are known relative to the ratio standard, any other k factors can be calculated using the formula

kAB = kAR / kBR

You can use any element if you are using theoretically derived k factors. Conventionally, Si is used.

也就是说是一个比较专业的参数，因子之类的吧
哈哈，被我蒙对了，客户问我代表啥意思，俺就瞎掰说，是一个因子，你们知道了也没用的

你真牛！！

K代表一个比例因子,是经过ZAF修正后得到的,以前手工定量计算时,K因子非常重要,但现在计算机发展了,可以直接得到定量结果,K因子对用户就不重要了

前面的百分比都分别代表什么啊？求解释，要用到能谱，菜鸟不懂分析

一般第一列是质量百分比,第二列是原子百分比，至于是用质量或原子百分比，就看用户自己了！
