Ngā Peera Hau o te Granite: Te Mahi a te Granite, ā, he aha te Granite te Rauemi Arataki Pai rawa atu

Ka tutuki i ngā peera hau te mea kāore e taea e te peera pā: te neke me te kore e pakaru, te kore e paheke, me te kore e whakahinuhinu, i ngā taumata tika iti iho i te maikorona. Engari ko te pai o te peera hau ko te mata e mānu ana. E whakamārama ana tēnei tuhinga i te ahupūngao o ngā kiriata hau, he aha te karāhe maori kikokore te rauemi pai mō te hononga, he aha te tika o te mata e hiahiatia ana e te arataki, me te wāhi e tino nui ai te uara o ngā papa peera hau karāhe - mai i ngā papa motuka raina ki ngā pūnaha tirotiro whatu.

1. Te Mahi a ngā Peera Hau: Te Eke i runga i te Kiriata Hau Makariri

Ka tautokona e te peera hau tōna kawenga i runga i tētahi kiriata angiangi pēhanga, he matotoru te nuinga o te wā, 3–15 µm. E rua ngā mātāpono tuku e tino kitea ana:

• Te utu mō te kōhao.Ka rere te hau mā roto i ngā kōhao i te rahi tika ki roto i tētahi pute papaku, i tētahi awaawa rānei; ka whakarerekē te pēhanga i a ia anō i te hurihanga o te āputa. He māmā noa iho, he pakari hoki, engari he taurite te kaha kawenga, ā, he tairongo te kiriata ki ngā hapa o te mata o te rohe.
• Whakautu pūwero.Ka rere ōrite te hau mā roto i tētahi rauemi pūangi (he waro te nuinga), ka puta he kiriata tino pumau, ātete-hohonu hoki me te whakaiti nui ake.

Ahakoa pēhea, he rite tonu te āhua o te ahupūngao matua: ko te pakari o te kiriata e whakawhirinaki ana ki te tapawhā o te ōritetanga o te āputa. Mena he rite te ngaru o te mata o te ara ārahi ki te matotoru o te kiriata, ka pāngia te atamira e te whakarerekētanga pēhanga — e kitea ana hei hapa tika, hei hurihuri, hei kino atu rānei, he hama hau (he oscillation whakaoho-ake).Ko te ara ārahi, ehara i te peera, e whakatakoto ana i te taumata kounga o te pūnaha.

2. He aha te Granite te Rauemi Arataki Pai rawa atu

I ētahi wā ka pātai ngā kaihangarau he aha te take e nui ai te whakamahi i ngā papa hau i runga i te karāhe, kaua i ngā reera maitai, uku rānei. Ko ngā take he ahupūngao rauemi, ehara i te tikanga tuku iho:

• He hanganga angiangi, ōrite.Ka totoka te kirikiri pango mura i te rewa kotahi; kāore he wehenga dendritic, he whakaurunga, he matrix ngohengohe rānei pērā i te rino maka. Mā te whakapiripiri ka kitea he mata ōrite, nō reira ka noho ōrite te āputa hau i te haerenga katoa - koinei te mea tino nui mō te pumau o te kiriata.
• He iti te horapa o te wera (≈5–8 µm/m·°C).He torutoru noa iho ngā maikorona o ngā āputa hau; ka taea e te haurua nekehanga o te huringa pāmahana te neke ake i te reera maitai i te āputa hau. Mā te pumau o te karāhe ka mau tonu te āhua o te kiriata i roto i ngā huringa awatea-pō.
• Kāore he waikura, kāore he hinu.Kāore e hiahiatia he paninga, he hinu whakahinuhinu rānei mō te karāhe tahanga — he mea nui tēnei i roto i ngā rūma ma, ina kore e taea te whakamahi i ngā reri hinu nā te mea ka puta he hau me te whakaputa matūriki.
• Te whakamākū teitei.Ka pehia e te whakakōkī ā-roto o te karāneti te tuku wiri mai i te papa me ngā puku, ka whakapai ake i te whanonga hihiri o te atamira mānu.
• Ka taea te whakamahi i te papatahi tae noa ki te taumata maikorano i runga i ngā mita.Ka taea te mirimiri ā-ringa i ngā reri karāhe roa, ā, ka taea te manatoko ki te torutoru maikoroni te rahi i roto i ētahi mita — he mea kāore e taea e te miihini anake te whakatutuki.

3. He aha te tika o te mata e hiahiatia ana mō te arataki whāriki hau?

Ko te whakatakotoranga e whakawhirinaki ana ki te momo peera me te kounga o te nekehanga ūnga, engari ko ngā whakaritenga noa mō te tikapeera hau karāhengā pūnaha ko:

Kāore e taea te wehe i te manatoko mai i ēnei tau: me ine i te tika i runga i te reriwe 2 mita te roa me te koretake o raro i te maikoroni me whai taumata hiko, autocollimators, laser interferometry rānei i roto i te rūma e whakahaeretia ana te pāmahana. Koia te take he rite te hiranga o te kaha ine a te kaiwhakarato ara ārahi ki ā rātou paepae papaki - ka whakaahuahia e mātou tā mātou huarahi i roto i tā mātoute tirotiro me te whakatikatika i te karāhetukanga

4. Ngā Whakamahinga Noa

• Ngā papaaho motuka raina.Ka tukuna e ngā motuka raina kore rino he kaha maeneene, kāore he whakakorikori; i te whakakotahitanga me ngā ara ārahi hau karāhe, ka eke ngā taumata ki te tika iti iho i te maikorona i te tere o te 1–2 m/s — te hoahoa paerewa mō te tirotiro i ngā papa me te matawai taiaho.
• Ngā wāhanga tika XY.Mā ngā atamira hau whakarārangi, papatahi rānei i runga i te turanga karāhe ka taea te whakahoki anō i te taumata-nanomita mō te ine ine e tata ana ki te ira, ngā kāri tirotiro me te tirotiro whakaaturanga.
• Ngā pūnaha tirotiro whatu.Me whai nekehanga matawai kore wiri, kore kakahu ngā pūnaha pūoko confocal, interferometric me te chromatic; kāore he matūriki, kāore hoki he hysteresis e tāpirihia ana e te kiriata kore-pa.
• Ngā taputapu whakataurite papatipu me ngā taiwhanga ine taumaha.Ko ngā kāreti hau i runga i ngā reera karāhe he mea e tika ana kia ma, kia tino tika hoki te āhua o te āhua.

I ēnei āhuatanga katoa, e rua ngā mahi a te karāhe i te wā kotahi: te turanga hanganga me te arataki tika. Mā te whakauru i ngā mea e rua ki roto i te rauemi kotahi — tētahi tukanga whakapiri, tētahi whanonga wera, tētahi tiwhikete — ka tangohia ngā atanga ka puta he hapa. He nui ake ngā taipitopito tono kei roto i tā mātoutaputapu haurua-irangā otinga.

5. Ngā Tuhipoka Hoahoa i mua i tō Tauwhāiti

1. Tautuhia te haere, te kawenga me te pokapū o te taumaha— ka inehia te pakari o te kiriata me te kawenga-mua o te peera huri noa i a rātou.
2. Tauwhāitihia te kounga o te hau— he hau ma, maroke te nuinga o te wā, me te tātari ki te 0.01 µm; ka rite te ma o te kiriata ki te puna tātari.
3. Whakatauhia te raraunga ine— nō wai te tohutoro tika: te kaihanga peera, te kaihanga turanga, te pūnaha kua huihui rānei?
4. Whakamaherehia te taiao— 20 ± 0.5 °C me te turanga motuhake-wiri e tiaki ana i te āhuahanga kua whakamanahia.
5. Tonoa te pūrongo tirotiro me te wāhanga— i ine i ngā uara tika/papatahi mā te tautuhi taputapu me te whai i ngā āhuatanga, kaua ko te reta tohu anake.

Whakamutunga

He takirua ōrite ngā peera hau me te karāneti: ka kore he nekehanga waku mā te peera, ā, ka puta he mata pumau āhuahanga, marino wera, kore matūriki mā te karāneti e āwhina ana i te kiriata kia mahi. Ina hangaia ngātahitia, ina manatokohia ngātahitia ngā mea e rua, ko te hua he kounga nekehanga e kore e taea e ngā pūnaha pa te tae atu.

Kei te whakawhanake koe i tētahi atamira kawe hau, i tētahi papa nekehanga rānei? Tukuna mai ki a mātou te whānuitanga haere, te kawenga, te tika e hiahiatia ana me te tuhi atanga — mā ZHHIMG® e hanga me te whakamana ngā wāhanga ara ārahi karāhe mō tō pūnaha, me tētahi pūrongo tirotiro ka taea te whai.
