On the kind of X-ray fluorescence spectroscopy of thin theory formula of intensity

Therefore, the measurement must be made by the workpiece and the standard ring to find inflection point the same direction, to reduce measurement error., after the use of refined table measuring 35 ~ 50mm diameter 40ram ring,[link widoczny dla zalogowanych], looking for inflection point in the same direction, ten cut the value of the three to find inflection point for the 0.4m, the maximum difference is also 0,4 Pro, this error is refined to allow the inner diameter of the table. Third, compared with refined After the lever of 40ram and 58ram diameter table were compared with measured workpiece, and then again on the horizontal length measurement device were measured, the comparison results in Table 2. pouch 2 units; mmd0 sequence hole diameter of 58 holes Rose Thousands Dan horizontal length measuring table but the table horizontal diameter Dan browse thousands of long {00540O0585795357.95230O0540.O0545793357.932640.00640005457.93357.9324000557.9335.93224000540.005557935503 ship {000540.005957.325.9324000540005357.953579a40O0540005257.93357. Mean 40Og5d0.O05557933579324 early 9521 can be seen this table, the difference between the two methods is small, this refined form of leverage have a higher diameter measurement accuracy. We will also use this method high precision large diameter ( 260ram, 370ram) test, also received a more satisfactory results.
