1. Yawancin hanyoyi guda biyu ne don gano digiri na vacuum, ɗaya shine a yi amfani da cikakken matsa lamba (watau cikakken vacuum digiri) don ganowa, ɗayan kuma shine amfani da matsin lamba (watau dangi vacuum degree) don ganowa.
2. Abin da ake kira "cikakkiyar matsa lamba" yana nufin cewa an haɗa famfo famfo zuwa akwati na ganowa. Bayan isasshen lokaci na ci gaba da yin famfo, matsa lamba a cikin akwati baya ci gaba da faduwa kuma yana kula da wani ƙima. A wannan lokacin, ƙimar iskar gas a cikin akwati shine cikakkiyar ƙimar famfo. matsa lamba. Idan babu isasshen iskar gas a cikin akwati, to cikakken matsa lamba sifili ne, wanda shine yanayin yanayin rashin amfani. A aikace, cikakken matsa lamba na injin famfo yana tsakanin 0 da 101.325KPa. Ana buƙatar auna madaidaicin ƙimar matsi tare da cikakken kayan aikin matsa lamba. A 20 ° C da tsawo = 0, ƙimar farko na kayan aiki shine 101.325KPa. A takaice dai, matsa lamban iska da aka gano tare da "theoretical vacuum" a matsayin ma'ana ana kiranta: "cikakkiyar matsa lamba" ko "cikakkiyar vacuum".
3. "Vacuum na dangi" yana nufin bambanci tsakanin matsi na abin da aka auna da yanayin yanayi na wurin aunawa. Aunawa tare da ma'auni na yau da kullun. Idan babu injin motsa jiki, ƙimar farko na tebur shine 0. Lokacin auna ma'aunin injin, ƙimar sa tsakanin 0 da -101.325KPa (yawanci ana bayyana shi azaman lambar mara kyau). Misali, idan ma'aunin ma'auni shine -30KPa, yana nufin ana iya jujjuya famfo zuwa yanayin da bai dace ba wanda ya kai 30KPa ƙasa da matsi na yanayi a wurin aunawa. Lokacin da aka auna famfo guda ɗaya a wurare daban-daban, ƙimar matsinsa na iya bambanta, saboda yanayin yanayi na wurare daban-daban na aunawa ya bambanta, wanda ke haifar da yanayi daban-daban na haƙiƙa kamar tsayi da zafin jiki a wurare daban-daban. A taƙaice, matsa lamban iska da aka gano tare da "ma'aunin ma'aunin yanayi" a matsayin ma'ana ana kiransa: "Matsayin dangi" ko "dangi vacuum".
4. Hanyar da aka fi sani da kimiyya a cikin masana'antar vacuum na duniya ita ce amfani da cikakkiyar alamar matsa lamba; Hakanan ana amfani da shi sosai saboda sauƙin hanyar auna ƙarancin dangi, kayan aunawa na gama gari, sauƙin siye da farashi mai arha. Tabbas, su biyun suna iya musanyawa a ka'ida. Hanyar juyawa shine kamar haka: cikakken matsa lamba = matsa lamba na iska a wurin ma'auni - cikakkiyar darajar matsa lamba.
