在用电的方法测量非电量方面虽然有了很大的进展,特别是采用了各种类型的固态传感器,但在工艺上仍然要求采用新的测量方法。尤其是在某些特定的环境下进行测量时,例如在极低温、极高温,高、低压条件下,以及在有各种类型的辐射源存在时,采用一般的电方法进行测量常常是不合适或者简直是不可能的。利用微波方法测量非电量有许多技术上和经济上的特点。我们知道,微波会透入非导电媒质或半导体媒质,在导电面上它将产生反射,它不影响被测物的属性(当采用的功率为中等电平时), Although great progress has been made in measuring the non-power consumption by means of electricity, especially using various types of solid-state sensors, new measurement methods are still required in the art. In general, it is not always appropriate to measure with conventional electrical methods, especially when measured under certain conditions, for example at very low temperatures, very high temperatures, high and low pressures, and in the presence of various types of radiation sources Or simply impossible. There are many technical and economical features for measuring non-electricity using microwave methods. We know that microwaves penetrate non-conductive or semiconductive media and have a reflection on the conductive surface that does not affect the properties of the DUT (when the power used is medium)
