Claim 8 Self-adjustable Temperature DeviceMethod for Step 2

• Decrease temperature 降低溫度– Phase transitions – E58_Joule-Thomson effect

焦耳 - 湯姆生效應 :

氣體在既不作功又不傳熱情況下因膨脹而引起的溫度變化 – Rank Effect – Magnetic calorie effect – E72_Thermoelectric phenomena

熱電效應

Claim 8 Self-adjustable Temperature DeviceMethod for Step 2

• Increase temperature 提高溫度– Electromagnetic induction – Vortical currents – Surface effect – Dielectric heating – Electronic heating – Electrical charges – Absorption of radiation by the substance – Thermo-electrical phenomena
