1. Check calibration of gloss meter with standard test block.

2. Austenite nodular cast iron test block with different thickness were cast from different saturation and CE, and the saturation and CE were verified by microstructure and mechanical properties.

3. The test block is cut from the casting and inspected to acquire the experimental data so as to monitor the quality of products.

4. The utility model relates to a special test block for ultrasonic flaw detection, which belongs to the technical field of the ultrasonic flaw detection.

5. The time-delay parameter test of time relay, SCM test block diagram and software flow chart are introduced.

6. The time - delay parameter test of time relay, SCM test block diagram and software chart are introduced.

7. This paper introduced time-delay parameter test of time relay, SCM test block diagram and software flowchart.

8. The feasibility of examining electrical porcelain insulator(EPI) with creeping wave probe was stu-(died, ) and a special test block was made for the experiment.

9. Considering low expense and high performance, the design and the realization of maintaining and monitoring system of cement test block has been discussed.

10. The utility model provides an ultrasonic fault detection comparing test block for a high-voltage pillar porcelain insulator, consisting of a test block body and arc grooves.

11. Owing to the loss of their adjacent material constraint, the residual stress on the cutting edge of the small test block reduces,(sentence dictionary) even changing from compressive stress to tensile stress.

12. Get hole of K value of angle probe and test block reference reflecting hole must be suitable.

13. Have a fixed attenuator series, short-circuit plug seat series, gold-plated jack series, pin series, test block series, EQ shell series accessories.

14. This paper designs a microcomputer system of the performance of the test block of a single cylinder for diesel engine. It can collect and treat all kinds of test data.
