4. the thrust measurement device was calibrated, and the accuracy was 2 % fs. at the same time the signal of thrust measurement was input to the computer. e - type chromel - constantan thermocouple was used to measure the temperature of mpt, and the accuracy was 5 % fs. the vacuum measurement was realized by using zdf - 5427m vacuometer, and the accuracy was 3 % fs
（ 4 ）對推力測量系統進行了標定並實現了計算機採集，推力測量系統最大相對誤差為2 fs ；溫度測量目前還只限於對mpt諧振腔壁溫的測量，使用e型鎳鉻?康銅熱電偶即可較容易實現，其測量精度為5 fs ；真空測量採用zdf - 5427m微機型復合真空計，其由熱偶計和熱陰極電離計復合而成，該真空計測量控制精度為3 fs 。
