由于对测量准确度的要求不断提高,必须在温度计中采用更为复杂的物理效应和仪器设备,才能保证提高将温度转变为等效电学量的灵敏度和稳定度。从这个观点来看.核四极共振可以把电磁振荡频率作为温度的信息当量,这是一种最有前途的效应。根据工作物质的类型不同,振荡频率的平均值在20～25MHz 之间,偏差为4～5kHz/K,因而能够发现0.001K
Due to the ever-increasing demands for measurement accuracy, more complex physical effects and instrumentation must be used in the thermometer to ensure increased sensitivity and stability in converting temperature to equivalent electrical quantities. From this point of view, nuclear quadrupole resonance can be the electromagnetic oscillation frequency as the information equivalent of temperature, which is one of the most promising effects. Depending on the type of work substance, the average oscillation frequency is between 20 and 25 MHz with a deviation of 4 to 5 kHz / K, so 0.001 K
