Txau Tshuab Ziab Khaub Ncaws

Hauv lub xyoo pua 20 thaum ntxov, cov tshuaj tsuag tshuab kom qhuav tau siv rau hauv cov khoom siv mis, uas muab cov cuab yeej muaj zog rau kev ziab khaub ncaws loj. Los ntawm xyoo 1940, nrog rau kev txhim kho ntawm kev hloov kho tshuab thev naus laus zis, lub zog siab thiab cov khoom lag luam siab fluidized txaj thiab cua ntws tshuab ziab khaub ncaws tau tshwm sim ib qho tom qab. Khov khov sublimation, hluav taws xob thiab tshuab hluav taws xob dielectric muab cov kev tshiab los ua kom tau raws li qhov tshwj xeeb.
