摘　　要：提出用液体电阻元件加热方法实现精密恒温的研究思想。根据这一想法设计的高精度精密恒温自动控制系统,已成功的应用于基因工程、生物工程、晶体培养等试验研究领域。测试证明:该系统比现行的固体电阻元件加热恒温性能优越,结构简化,其恒温极限误差小于±0.02℃,控温精度提高90倍。A heat method of using liquid resistance to realize rigid temperature control was proposed. A high precision temperature autocontrol system was designed based on the idea above, it has been successful applied in the research fields of bioengineering, crystal incubate etc. The test proved that it has better heat performance and simplified structure compared with the actual solid resistance component. Its ultimate error is less than ±0.02℃ and its precision is increased by a factor of ninety.
