Ko te FDR te tikanga whakatinanatanga motuhake o te hangarau ine makuku oneone tino rongonui o nāianei. Mā te ine i te pūmau dielectric (pānga capacitance) o te oneone ka taea te tiki tere, ā-korekore hoki i te nui o te wai o te oneone. Ko te kaupapa matua he tuku i tētahi tohu ngaru hikohiko o tētahi auau motuhake (te nuinga o te wā 70-150 MHz) ki roto i te irahiko (tirotiro) kua whakaurua ki roto i te oneone, ā, ka ine i te auau resonant, i te huringa aukati rānei e whakatauhia ana e ngā āhuatanga dielectric o te oneone, kia tātaihia ai te pūmau dielectric me te nui o te makuku.
Ko ngā āhuatanga taipitopito o te pūoko oneone FDR ēnei e whai ake nei:
Ngā kaha me ngā painga matua
He tere, he tonu, he aunoa hoki te ine
Ka taea e ia te whakatutuki i te ine tonu i te taumata tuarua, i te tere ake rānei, kia tino pai ai mō ngā horopaki e hiahia ana ki te tuhi raraunga taumira teitei, te whakahaere whakamakuku aunoa, me te rangahau tukanga hihiri.
He utu nui te mahi, he ngāwari hoki te rongonui
Ki te whakaritea ki ngā pūoko TDR (Time Domain Reflectometry) he tika ake, he utu nui ake hoki, he māmā ake te hoahoa me te hanga o te ara iahiko FDR, ā, he tino iti ake te utu, he mea pai rawa atu mō te whakatinanatanga nui i roto i ngā mara pēnei i te ahuwhenua atamai me te whakapaipai whenua.
He iti rawa te whakamahinga hiko
He iti rawa te hiko e whakamahia ana e te ara iahiko ine, ko te iahiko taumata-miliampere anake te tikanga e hiahiatia ana, nō reira he tino pai mō ngā teihana aroturuki parae me ngā pūnaha Ipurangi o ngā Mea e whakakahangia ana e ngā pākahiko me ngā panera rā mō te wā roa.
He ngāwari te hoahoa o te pūwero, ā, he ngāwari hoki te tāuta
He maha ngā āhua o ngā taputapu tātari (pēnei i te momo tokotoko, te momo poka, te momo kōtaha maha-hohonu, me ētahi atu), ā, me whakauru noa ki roto i te oneone. He iti noa te kino o te hanganga oneone, ā, he tino ngāwari te tāuta.
He pai tōna pumau, ā, he teitei hoki te haumarutanga
Kāore he matū irahiko i roto (he rerekē i ngā mita niutron), he haumaru te whakamahi, ā, he pumau te mahi a ōna wāhanga hiko, e āhei ai te mahi mō te wā roa.
He ngāwari ki te whakauru me te whatunga
He hototahi ā-tūturu ki te hoahoanga Ipurangi o ngā Mea hou, ā, ka taea te whakauru ngāwari i ngā waeine tuhi raraunga me te tuku ahokore hei hanga i tētahi whatunga aroturuki makuku oneone tauine nui.
Ngā herenga me ngā wero matua
Ka pāngia te tika o te ine e ngā āhuatanga oneone (ngā herenga matua)
Kakano oneone me te mātotoru papatipu: Ka rerekē te whanaungatanga (te pihi whakatikatika) i waenga i te pūmau dielectric me te nui o te wai i waenga i ngā oneone he rerekē te nui o te uku, te onepu, me te mea rauropi. Ka taea e ngā tātai whakatikatika whānui te arahi ki ngā hapa.
Te kawe hiko o te oneone (te tote): Koinei tētahi o ngā mea tino nui e pā ana ki te tika o te FDR. Ka taea e ngā katote kawe hiko i roto i te otinga oneone te whakararu i te kaha tohu, ka hua ake he uara ine pūmau dielectric kua piki ake, ā, ka nui rawa te whakatau i te nui o te wai. I roto i te whenua tote-kawakore, tera pea he tino nui tēnei hapa.
Pāmahana: Ka pāngia te pūmau dielectric o te oneone e te pāmahana. Kei ngā tauira papai ngā pūoko pāmahana kua hangaia hei utu, engari kāore e taea te whakakore katoa i tēnei.
Te pā o te pūwero me te oneone: Mena he āputa kei te toe, he kore rānei te pā e mārō i te wā e tāuta ana, ka tino whakararuraru i te ine.
Me whakahaere te whakatikatika i te papaanga kia tika ai te mahi
Ko te whakatikatika wheketere e ahu mai ana i tētahi momo paerewa (pērā i te onepu me te oneone). Hei whiwhi i ngā uara tino pono, me mahi te whakatikatika i te papaanga i roto i te oneone ūnga (arā, mā te whakatairite ki ngā uara i inehia o te tikanga whakamaroke me te whakatū i tētahi whārite whakatikatika ā-rohe). He taahiraa nui tēnei hei whakarite i te kounga o te rangahau pūtaiao me te whakahaere raraunga tika, engari ka piki ake hoki te utu whakamahinga me te paepae hangarau.
Ko te awhe ine he mōhiohio "ira" ā-rohe
Ko te wāhi tairongo o te pūoko he iti noa iho i te torutoru henimita kūpiko o te rōrahi oneone huri noa i te taputapu tirotiro. Hei whakaahua i te rerekētanga ā-wāhi o ngā whenua nui, me whakahaere he tahora maha-ira whaitake.
Te pumau me te nekenekehanga mō te wā roa
I muri i te tanumanga mō te wā roa, ka rerekē pea ngā āhuatanga ine mai i te whakarewa o te ine nā te waikura hikohiko, te poke rānei, ā, me tirotiro me whakatikatika anō i ia wā.
Ngā horopaki e tika ana kua tūtohutia
Ngā horopaki tino tika
Te ahuwhenua tika me te whakamakuku atamai: Te aroturuki i ngā whanaketanga makuku oneone, te arotau i ngā whakataunga whakamakuku, me te whakatutuki i te tiaki wai me te whakapai ake i te whai huatanga.
Rangahau ā-taiao me te wai: Te aroturukitanga pūmau mō ngā huringa o te makuku o te oneone mō te wā roa.
Te tiaki i te māra me te papa korowha: Ngā pūoko matua o ngā pūnaha whakamakuku aunoa.
Aroturukitanga ā-pāpāho whenua: Whakamahia hei whakatūpato wawe i te nui o te wai i roto i te aroturukitanga o te pumau o te pari.
Ngā āhuatanga e tika ana kia tūpato, kia tangohia rānei he mahi ārai:
Mō te oneone tote, te oneone kawe wai nui rānei: Me whiriwhiri ngā tauira me ngā mahi whakatikatika tote, ā, me whakahaere i te whakatikatika tino tika i runga i te papaanga.
I ngā āhuatanga e hiahiatia ana te tika tuturu e te ture, e te taumata rangahau rānei: Me whakarite me te whakatikatika ki ngā tikanga TDR, ki ngā tikanga whakamaroke rānei, ā, me whakahaere hoki i ngā arowhai auau.
Whakarāpopototanga
Nā te utu pai rawa atu, te iti o te whakapaunga hiko me te ngāwari o te whakamahi, kua noho ko ngā pūoko oneone FDR te hangarau ine makuku oneone e whakamahia whānuitia ana i roto i ngā mahi ahuwhenua hou me te aroturuki taiao. Ko te tikanga he "tirotiro whai hua i runga i te papa".
Ka taea te whakarāpopoto i ngā āhuatanga matua penei:
Ngā Painga: Tere, tonu, iti te utu, iti te whakapaunga hiko, me te ngāwari ki te whatunga.
Ngā Here: Ka pāngia ngāwari te tika e te tote o te oneone, te kakano me te pāmahana, ā, me whakatikatika i te wāhi e tika ai.
Mā te mārama tika ki ōna āhuatanga me te whakahaere i ōna hapa mā te whakatakotoranga pūwāhi pūtaiao me te whakatikatika e tika ana, ka taea e ngā pūoko FDR te whakarato i ngā mōhiohio hihiri tino whai hua mō te makuku oneone, ā, he taputapu matua hoki mō te whakahaere rauemi wai tika me te whanaketanga o te ahuwhenua matihiko.
