4. Summary
4.1 Overview
Industrial CT systems Key features include.
a) spatial resolution;
b) the density resolution.
4.2 Spatial resolution
Spatial resolution tests are typically wired for Kapha, Kapha disc, hole card method, you can select a specific method according to the actual situation. Pairs
Card production requirements, the testing process is simple, intuitive test results. Disk card production is relatively simple, complex testing process, test results need complicated
Calculations. Hole card production requirements, the testing process is simple, the results of the test process more difficult. Line of cards, hole cards, cards and other standard disk specimens
Design and production requirements, see Appendix A, respectively A.1, A.2, A.3.
4.3 Density Resolution
Resolution density tests are usually air-gap method, disc Kapha, density difference, you can select a specific method according to the actual situation. air
Air gap higher card production, testing process is simple, intuitive test results. Disk card production is relatively simple, complex testing process, test results have to be
To calculate complicated. Density difference method difference method difference method are two solid density and density of the liquid; liquid density standard specimens difficult to produce, susceptible to temperature
The impact of small differences in the density of the solid density standard specimen is difficult to obtain, usually an air gap card replacement; density difference method testing process is simple, measuring
Test results intuitive. Air gap cards, liquid density difference between the standard test piece, solid density difference between the standard specimen design and production requirements of Appendix respectively
A.4 A's, A.5, A.6.
