| Abstract: | This paper analyzes the measurement error of the capacitance film vacuum gauge in the combined astronaut-module-spacesuit test. It is shown that the error comes from the improper use of the gauges, and some improvement is accordingly suggested for the vacuum degree measurement system. The upgraded system is shown to be capable of fulfilling the combined astronaut-module-spacesuit test. |
