     The on-line control software can order the XRD system to do continuous scanning or step

scanning and data acquisition. The software can process the general diffraction data and manage the disk file. Data processing including peak seeking (automatic and manual), single peak integral intensity calculation, smoothing, peak shape amplification, multiple drawing, etc .

6.   Application software (English Interface)

8.1  Operation functions:

      Diffraction peak measurement, overlap scanning, net intensity measurement, timer counter, goniometer rotating, goniometer step forward and back, goniometer adjustment, 2θcalibration, tube current and tube voltage optical shutter controlling.

8.2  Data analysis and processing function:

8.2.1  Smoothing, background deduction, Kα2 Peeling, peak seeking(mark D value,θvalue, d,2θintensity, half-peak bandwidth, display all parameters and many representing methods of diffraction peak), changing sampling step, eliminating , eliminating miscellaneous peak and Interfering peak, d data and peak position correction.

8.2.2 Calculate integral area, integral breadth, half-peak bandwidth; Spectral graph comparison, map add and subtract, and map combination; Insert text at any location in the map; Two kinds of cursors (small vernier, large cursor);Multiple zoom function; Multiple coordinate modes (linear coordinates, logarithmic coordinates, square coordinates).

8.2.3  Peak amplification: user can make any multiple of any multiple of the map by the left and right keys of the mouse.

8.3   Qualitative analysis:

Automatic retrieval and manual retrieval can be performed. Automatic retrieval results include: card number, molecular formula, matching index, reliability factor, and K value. Semi-quantitative analysis and k-value analysis can be carried out.

8.4   Quantitative analysis:

The absorption coefficient of the two components is different with the standard addition method, internal standard method and N component absorption coefficient.

8.5   The crystallinity of the sub-peak method is calculated

The partial peak process can directly change the parameters of the sub-peak by the mouse, and the difference between the fitting spectrum and the measured spectrum can be seen intuitively.

8.6   It can do refinement of cell parameters.

8.7   Index.

8.8  Diffraction data calibration:

          Using standard diffraction data CARDS (1-54 groups), the original data of the measurement was deviated to correct and the instrument measurement error was eliminated.
