Read the passage and fill in the blank to complete the logically valid conclusion.
Answer:Industrial gas turbines utilize ceramic matrix composite liners that withstand continuous operating temperatures up to 1,200 degrees Celsius without auxiliary cooling. Whenever combustion chamber temperatures surpass this limit, an automated bypass valve actively injects compressor bleed air into the chamber to prevent thermal degradation. During an uncooled full-power test run, telemetry confirmed steady engine output while the bypass valve remained continuously shut. Based on these operating parameters, it can be logically concluded that the combustion temperature during the test remained 【below】 1,200 degrees Celsius.
Answer
The combustion temperature remained below (or at or below) 1,200 degrees Celsius.
The passage states that the bypass valve actively opens when combustion chamber temperatures exceed 1,200 degrees Celsius. Since telemetry showed that the valve remained continuously closed throughout the test run, the threshold to trigger the valve was never reached, proving logically that combustion temperatures stayed at or below 1,200 degrees Celsius.
