I-FDR iyindlela ethile yokusebenzisa ubuchwepheshe bokulinganisa umswakama wenhlabathi obusetshenziswa kakhulu njengamanje. Ithola ngokungaqondile nangokushesha okuqukethwe kwamanzi enhlabathini ngokulinganisa i-dielectric constant (umphumela we-capacitance) yenhlabathi. Umgomo ukukhipha isignali yegagasi le-electromagnetic yemvamisa ethile (ngokuvamile i-70-150 MHz) ku-electrode (i-probe) efakwe enhlabathini, bese ilinganisa imvamisa ye-resonant noma ushintsho lwe-impedance olunqunywe yizakhiwo ze-dielectric zenhlabathi, ngaleyo ndlela kubalwa i-dielectric constant kanye nokuqukethwe komswakama.
Okulandelayo yizici ezinemininingwane zenzwa yomhlabathi ye-FDR:
Amandla nezinzuzo eziyinhloko
Ukulinganisa kuyashesha, kuyaqhubeka futhi kuyazenzakalela
Ingafinyelela ukulinganisa okuqhubekayo ezingeni lesibili noma ngokushesha okukhulu, okwenza ifaneleke kakhulu ezimweni ezidinga ukuqoshwa kwedatha enesisombululo esiphezulu sesikhathi, ukulawulwa kokunisela okuzenzakalelayo, kanye nocwaningo lwenqubo oluguquguqukayo.
Ukusebenza okubiza kakhulu futhi kulula ukuthandwa
Uma kuqhathaniswa nezinzwa ze-TDR (Time Domain Reflectometry) ezinembile futhi ezibizayo, ukwakheka kanye nokukhiqizwa kwesekethe ye-FDR kulula, futhi izindleko zincishisiwe kakhulu, okwenza kube ukukhetha okuhle kokusetshenziswa okukhulu emikhakheni efana nezolimo ezihlakaniphile kanye nokuhlobisa ingadi.
Ukusetshenziswa kwamandla okuphansi kakhulu
Ukusetshenziswa kwamandla kwesekethe yokulinganisa kuphansi kakhulu, ngokuvamile kudinga kuphela ugesi wezinga le-milliampere, okwenza kube kuhle kakhulu eziteshini zokuqapha insimu kanye nezinhlelo ze-Intanethi Yezinto ezisebenza ngamabhethri namaphaneli elanga isikhathi eside.
I-probe iklanywe ngendlela eguquguqukayo futhi kulula ukuyifaka
Ama-probe eza ngezindlela ezahlukene (njengohlobo lwenduku, uhlobo lokubhoboza, uhlobo lwephrofayili ejulile, njll.), futhi adinga ukufakwa enhlabathini kuphela. Awadali umonakalo omkhulu esakhiweni senhlabathi futhi kulula kakhulu ukuwafaka.
Inokuqina okuhle kanye nokuphepha okuphezulu
Ayinazo izinto ezinemisebe (ngokungafani namamitha e-neutron), iphephile ukuyisebenzisa, futhi izingxenye zayo ze-elekthronikhi zizinzile ekusebenzeni, okuvumela ukusebenza kwesikhathi eside.
Kulula ukuhlanganisa nokuxhumana
Ihambisana ngokwemvelo nokwakhiwa kwesimanje kwe-Internet of Things futhi ingahlanganisa kalula amamojula okuqopha idatha kanye nokudlulisa okungenantambo ukwakha inethiwekhi enkulu yokuqapha umswakama wenhlabathi.
Imikhawulo emikhulu kanye nezinselele
Ukunemba kokulinganisa kuthintwa izici ezahlukahlukene zenhlabathi (imikhawulo eyinhloko)
Ukuthungwa kwenhlabathi kanye nobuningi bayo: Ubudlelwano (ijika lokulinganisa) phakathi kwe-dielectric constant kanye nokuqukethwe kwamanzi kuyahlukahluka phakathi kwenhlabathi enokuqukethwe okuhlukile kobumba, isihlabathi, kanye nezinto eziphilayo. Amafomula okulinganisa ajwayelekile angaholela emaphutheni.
Ukuqhuba kukagesi komhlabathi (usawoti): Lesi ngesinye sezici ezibaluleke kakhulu ezithinta ukunemba kwe-FDR. Ama-ion aqhubayo esixazululweni senhlabathi angabangela ukulahleka kwamandla esignali, okuholela enanini lokulinganisa elingaguquki le-dielectric futhi ngaleyo ndlela kulinganiswe ngokweqile okuqukethwe kwamanzi. Ezweni le-saline-alkali, leli phutha lingaba likhulu kakhulu.
Izinga Lokushisa: I-dielectric constant yenhlabathi ithintwa izinga lokushisa. Amamodeli aphezulu afakwe izinzwa zokushisa ezakhelwe ngaphakathi ukuze zibuyisele, kodwa lokhu akukwazi ukususwa ngokuphelele.
Ukuthintana phakathi kwe-probe nenhlabathi: Uma kukhona isikhala esisele noma ukuthintana kungaqinile ngesikhathi sokufakwa, kuzophazamisa kakhulu ukulinganiswa.
Ukulinganiswa kwendawo kumele kwenziwe ukuze kulandelwe ukunemba okuphezulu
Ukulinganiswa kwefektri kuvame ukusekelwe endaweni ethile ejwayelekile (njengesihlabathi nomhlabathi). Ukuze kutholakale amanani aphelele athembekile, ukulinganiswa endaweni kumele kwenziwe enhlabathini eqondiwe (okungukuthi, ngokuqhathanisa namanani alinganisiwe endlela yokomisa nokusungula i-equation yokulinganisa yendawo). Lesi yisinyathelo esibalulekile sokuqinisekisa ikhwalithi yocwaningo lwesayensi kanye nokuphathwa kwedatha okunembile, kodwa futhi kwandisa izindleko zokusetshenziswa kanye nomkhawulo wobuchwepheshe.
Ububanzi bokulinganisa ulwazi lwendawo "lwamaphuzu"
Indawo ebucayi yenzwa ivame ukulinganiselwa kumasentimitha ambalwa e-cubic omthamo wenhlabathi ezungeze i-probe. Ukuze kuchazwe ukuguquguquka kwendawo yamasimu amakhulu, kubalulekile ukwenza ukwakheka okunengqondo kwamaphuzu amaningi.
Ukuqina kwesikhathi eside kanye nokuzulazula
Ngemva kokungcwatshwa isikhathi eside, insimbi ye-probe ingabangela ukuthi izici zokulinganisa zikhukhuleke ngenxa yokugqwala noma ukungcola kwe-electrochemical, futhi ukuhlolwa nokulungiswa kabusha okuvamile kuyadingeka.
Izimo eziphakanyisiwe ezisebenzayo
Izimo ezifanele kakhulu
Ezolimo ezinembile kanye nokunisela okuhlakaniphile: Ukuqapha ukuguquguquka komswakama wenhlabathi, ukwenza izinqumo zokunisela zibe ngcono, kanye nokufeza ukongiwa kwamanzi kanye nokuthuthukiswa kokusebenza kahle.
Ucwaningo lwezemvelo kanye nolwamanzi: Ukuqapha isikhathi eside izinguquko zephrofayili yomswakama wenhlabathi.
Ukugcinwa kwengadi nenkundla yegalofu: Izinzwa eziyinhloko zezinhlelo zokunisela ezizenzakalelayo.
Ukuqapha izinhlekelele ze-geology: Kusetshenziselwa isexwayiso sangaphambi kwesikhathi sokuqukethwe kwamanzi ekuqapheni ukuzinza kwemithambeka.
Izimo lapho kudingeka khona ukuqaphela noma izinyathelo zokuzivikela kufanele zithathwe:
Enhlabathini enosawoti noma eqhuba kahle: Amamodeli anemisebenzi yokunciphisa usawoti kumele akhethwe futhi kufanele kwenziwe ukulinganisa okuqinile endaweni.
Ezimweni lapho kunezidingo zomthetho noma ezingeni locwaningo zokunemba okuphelele: Kuyadingeka ukuqhathanisa nokulinganisa nge-TDR noma izindlela zokomisa, futhi kufanele kwenziwe ukuhlolwa okuvamile.
Isifinyezo
Izinzwa zenhlabathi ze-FDR, ngokusebenza kwazo okuhle kakhulu kwezindleko, ukusetshenziswa kwamandla aphansi kanye nokulula kokusetshenziswa, sezibe ubuchwepheshe bokulinganisa umswakama wenhlabathi obusetshenziswa kakhulu kwezolimo zanamuhla kanye nokuqapha imvelo. Empeleni "iyindlela yokuhlola esebenza kahle endaweni".
Izici eziyinhloko zingafingqwa kanje:
Izinzuzo: Iyashesha, iyaqhubeka, ishibhile, isebenzisa amandla aphansi, futhi kulula ukuyixhumanisa.
Imikhawulo: Ukunemba kuthinteka kalula usawoti wenhlabathi, ukuthungwa kanye nokushisa, futhi kudingeka ukulinganiswa endaweni ukuqinisekisa ukunemba.
Ngokuqonda kahle izici zayo nokuphatha amaphutha ayo ngokuhlelwa kwamaphuzu esayensi kanye nokulinganiswa okudingekayo, izinzwa ze-FDR zinganikeza ulwazi oluwusizo kakhulu oluguquguqukayo mayelana nomswakama wenhlabathi futhi zingamathuluzi abalulekile okuphathwa kwemithombo yamanzi okunembile kanye nokuthuthukiswa kwezolimo zedijithali.
