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 。 -
The sample temperature was controlled by a chromel _ alumel thermocouple with a precision on the order of 0. 1
此次田間試驗的目的，是研究這一方法能在多大程度上防止由於精細的作物輪作所產生的土壤退化。
