In static state characteristic test, pressure gain characteristic, runoff characteristic with load, runoff characteristic without load and leakage characteristic are completed.

This paper mainly introduces a test method of altitude measurement in a static state for a new type of a pulse radar altimeter installed in a CK1E target drone model.

The absorption capability, the regeneration capability and the influencing factors of the clinoptilolite to ammonia nitrogen are studied through static state test , dynamic test and regenerative test.
