In fact, SE is the standard deviation of the fitted parameter obtained from the nonlinear regression. There is no difference between SE and SD when we talk about fitted parameters in the curve fitting. Keywords:SE, SD, parameter, nonlinear curve fit, standard error, standard deviation...
The average crystallite sizes of the synthesized powders were determined from the full-width at half-maximum (FWHM) of the XRD diffraction peaks us X-射线催化剂的绕射图得到了在10-808范围内与衍射计Philips微微瓦1.050781,使用Ni被过滤的Cu钾辐射(l = 1.5432 A˚)。 被综合的粉末的平均晶子大小从...
The measured full width at half maximum (FWHM) from the XRD rocking curves is obtained by rotating the sample through the Bragg angle after the angle (θ) and the detector position (2θ) are fixed at the Bragg angle of the corresponding reflection. The FWHM is used to determine ...
aAs seen from the XRD patterns in Fig. 2, the full-width at half-maximum (FWHM) of (0 4 0)diffraction for the films were obviously varied with the annealing temperatures. 如从XRD样式被看见在。 2,全宽在一半最大值(FWHM) (0 4 0)衍射为films随焖火温度明显地变化了。[translate] ...
