Embodiment 2
[0099] This embodiment proposes a method for filtering probe signals under the Jialajieya device, which includes the following steps:
[0100] S1: Prepare the probe and install it in the Jiala Jieya device; in S1, prepare the probe as figure 2 As shown, using materials such as 0.5mm tungsten wire 5, ceramic sleeve 3, ceramic sleeve 4, corundum ceramic powder 2, zero-water sodium metasilicate, high temperature resistant insulating wire 1 and other materials to trial-manufacture Langmuir probes, compare different corundum ceramic powder, The structural stability of the Langmuir probe under the ratio of zero-water sodium metasilicate and water, using corundum ceramic powder mixed with zero-water sodium metasilicate can more conveniently fix the tungsten wire 5 in the ceramic tube, and obtain better For the fixing effect, the best ratio is 1:1.5:1 through experiments. At this time, the coagulation time and the fixing effect can be considered to achieve better results.
