1. Comparing with X-ray spectrum, sulfur state and content in strontium ore waste slag is got by the barium sulphate method and iodometry with only 0.37% of deviation.

2. Methods: Using x-ray spectrum and the atom spectrum analysis technique in medicine research's method.

3. This paper provides the first measurement results of X-ray spectrum at the beam lines of synchrotron radiation. It describes the detector and spectral system, measuring method and data acquisition.

4. This paper introduced the application of X-ray spectrum in the researching of superconductors briefly.

5. This paper introduced the application of x-ray spectrum in the researching of superconductors briefly.

6. The sub- keV X-ray spectrum from source region and implosion region were measured by two sub- keV X-ray energy spectrometers respectively through laser incidence hole and diagnostic hole.

7. The absolute intensity of the soft x-ray spectrum from laser plasma has bean measured.

8. This and the X-ray spectrum, which exhibits a high concentration of iron atoms relative to oxygen and silicon, convincingly show that the ejecta are the remains of an exploded white dwarf star.

9. An energy dispersive X-ray spectrum obtained from a rat adrenal chromaffin granule.

10. In this paper, the derivative deconvolution method is applied to practical X - ray spectra, therefore the resolution of x-ray spectrum has been enhanced, and the overlapped peaks have been resolved.

11. The broadband soft X-ray spectrometer and flat response detector are used to measure the soft X-ray spectrum and its angular distribution from the diagnostic hole on cavity target.

12. The method of filter difference, which is used to measure X-ray spectrum radiated from laser produced plasma, are studied.

13. The structural and magnetic properties of the granular film are studied by atomic force microscope, energy dispersion X-ray spectrum, X-ray diffraction, and alternating gradient magnetometer.

14. At the same time, some signal processing for our X-ray spectrum data were completed, such as display smoothing, Max finding and power scale.

15. Due to the existence of interference and nonlinear background in X-ray spectrum, there are errors in the results of quantitative analysis on electron probe, especially for the lower element content.

16. It is the common phenomenon that the spectral peaks are overlapped in the x-ray spectrum.

16. try its best to gather and build good sentences.

17. The energy aberration of crystal monochromator in the case of continuous X-ray spectrum, for instance EXAFS, has been discussed.

18. X-ray spectrum analysis is the mathematic way used to advance the precision and to get the more information from the X-ray spectrum.
