cold junction 中文意思是什麼
cold junction
解釋
冷端-
Microwave power dissipated in ta2n resistive film generates heat to raise the temperature of the hot junction above that of the cold junction, thereby producing a dc voltage across the thermocouple. we can measure microwave power through measuring this dc voltage
微波功率耗散在ta2n電阻上轉變成熱能使熱結溫度高於冷結,這樣冷熱結兩端就產生一個熱電勢,通過測量該熱電勢即可實現微波功率測量。
