Ko ngā whirihoranga taura tungsten tino noa i roto i ngā karetao pokanga ko te 8×19, 7×37, me te 19×19. Ko te taura miihini me te waea tungsten 8×19 kei roto ko ngā waea tungsten 201, ko te 7×37 kei roto ko ngā waea 259, ā, ko te 19×19 kei roto ko ngā waea aho porowhita 361. Ahakoa e whakamahia ana te maitai kore waikura i roto i ngā momo tono, tae atu ki ngā taputapu hauora me ngā taputapu pokanga maha, kāore he mea hei whakakapi i ngā taura tungsten i roto i ngā karetao pokanga.
Engari he aha te take e iti haere ai te rongonui o te kowiri tira, he rauemi rongonui mō ngā taura mīhini, i roto i ngā puku karetao pokanga? Nā te mea, he maha ngā taura kowiri tira, inā koa ngā taura iti-diameter, i roto i ngā mahi hōia, rererangi, me te mea nui, te tini o ngā mahi pokanga.
Āe, ko te take e whakakapia ai e ngā taura tungsten te maitai kore waikura i roto i te whakahaere nekehanga karetao pokanga ehara i te mea ngaro e ai ki te whakaaro: he mea e pā ana ki te pakari. Engari i te mea ko te kaha o tēnei taura miihini ehara i te mea ka inehia e tōna kaha kume raina anake, me whakamātautau tātou i te kaha hei ine i te mahi mā te kohikohi raraunga mai i ngā āhuatanga maha e tika ana mō ngā āhuatanga o te mara.
Hei tauira, me tango te hanganga 8×19. Hei tētahi o ngā hoahoa taura miihini e whakamahia whānuitia ana hei whakatutuki i te piko me te yaw i roto i ngā karetao pokanga, he nui ake te pai o te mahi a te 8×19 i te taura kowiri tira ina piki haere te kawenga.
Kia mōhio koe i piki ake te wā huringa me te kaha kume o te taura tungsten i te pikinga o te kawenga, i te mea i heke nui te kaha o te taura kowiri tira rerekē ki te whakataurite ki te kaha o te tungsten i te kawenga kotahi.
Ko te taura maitai kore waikura he 10 pauna te taumaha, ā, ko te whānui tata ki te 0.018 inihi te whānui, e 45.73% noa iho o ngā huringa e tutukihia ana e te tungsten me te hoahoa 8×19 me te whānui waea rite tonu.
Ina hoki, i whakaatu tonu tēnei rangahau ahakoa te 10 pauna (44.5 N), he rua ngā wā e mahi ai te taura tungsten i te taura kowiri tira. I te mea, pērā i ngā wāhanga katoa, me tutuki, me hipa rānei ngā taura moroiti i roto i te karetao pokanga i ngā whakaritenga ture pakari, me kaha te taura ki te tu atu i ngā mea katoa e whiua ana ki a ia, tika? Nō reira, e whakaatu ana te tātaritanga he painga kaha ā-roto te whakamahi i te taura tungsten 8×19 te diameter rite ki te taura kowiri tira, ā, ka whakarite kia whakakahangia te karetao e te rauemi taura kaha ake, pakari ake hoki o ngā kōwhiringa e rua.
Hei tāpiritanga, mō te hoahoa 8×19, ko te maha o ngā huringa o te taura waea tungsten he 1.94 ngā wā neke atu i te taura waea kowiri tira he rite te whānui me te kawenga. I tua atu, kua whakaatuhia e ngā rangahau kāore e taea e ngā taura kowiri tira te rite ki te ngāwari o te tungsten, ahakoa ka piki haere te kawenga i tukuna mai i te 10 ki te 30 pauna. Inaa, kei te piki haere te āputa i waenga i ngā rauemi taura e rua. Mē te kawenga ōrite o te 30 pauna, ka piki ake te maha o ngā huringa ki te 3.13 ngā wā. Ko te kitenga nui ake ko te korenga o ngā tawhā i heke (ki te 30 ngā tohu) puta noa i te rangahau. He nui ake te maha o ngā huringa o te tungsten, ko te toharite he 39.54%.
Ahakoa i tirotirohia e tēnei rangahau ngā waea o ngā diameter motuhake me ngā hoahoa taura i roto i tētahi taiao e tino whakahaerehia ana, i whakaatuhia e ia he kaha ake te tungsten, ā, he maha ake ngā huringa e whakaratohia ana me ngā ahotea tika, ngā kawenga kume, me ngā whirihoranga pūrakau.
He mea tino nui te mahi tahi me tētahi miihini hanga tungsten hei whakatutuki i te maha o ngā huringa e hiahiatia ana mō tāu tono karetao pokanga.
Ahakoa he kowiri tira, he tungsten, he momo taura mīhini rānei, kāore e rua ngā taura e whakamahi ana i te takai tuatahi kotahi. Hei tauira, ko ngā taura iti te tikanga kāore e hiahiatia ngā aho, me ngā taunga piri o ngā hononga e pā ana ki te taura.
I ngā wā maha, he ngāwari te whiriwhiri i te roa me te rahi o te taura tonu, tae atu ki te wāhi me te rahi o ngā taputapu. Ko ēnei ine te mea e whakamana ana i te huihuinga taura. Mena ka taea e tō kaihanga taura miihini te whakatinana i ngā huihuinga taura e tutuki ana i ngā whakamana o te tono, ka taea anake te whakamahi i ēnei huihuinga i roto i tō rātou taiao tūturu.
Mō ngā karetao pokanga, kei reira ngā oranga e tūpono ana, ko te whakatutuki i ngā paerewa hoahoa anake te hua e whakaaetia ana. Nō reira, he tika ki te kī ko ngā taura miihini tino angiangi e whai ana i ia nekehanga a te taote pokanga ka waiho ēnei taura hei ētahi o ngā taura tino matatau o te ao.
He iti, he whāiti hoki ngā wāhi e nohoia ana e ngā taura mīhini e uru ana ki roto i ēnei karetao pokanga. He mea whakamiharo te uru pai o ēnei taura tungsten ki roto i ngā awaawa whaiti rawa, i runga i ngā pūreirei kāore e nui ake i te pito o te pene a te tamaiti, ā, ka taea e rātou te mahi i ngā mahi e rua me te pupuri tonu i te nekehanga i te maha o ngā huringa e taea te matapae.
He mea nui anō hoki kia mōhio koe ka taea e tō kaihanga taura te tuku tohutohu i mua i te wā, ka penapena pea i te wā, i ngā rauemi, tae atu ki ngā utu, he mea nui ēnei hei whakarite i tētahi rautaki hokohoko pai mō tō karetao.
I te tere tipu haere o te mākete karetao pokanga, kāore e whakaaetia ana te whakarato noa i ngā taura miihini hei āwhina i te nekehanga. Ko te tere me te tūranga e kawe mai ai ngā kaihanga karetao pokanga i ā rātou mahi whakamiharo ki te mākete ka whakawhirinaki ki te ngāwari o te whakarite i ngā hua mō te kai nui. Koia te mea nui kia mōhio koe me rangahau, me whakapai ake, me hanga hoki e ō kaihanga miihini ēnei huihuinga taura i ia rā, i ia rā.
Hei tauira, he maha ngā wā ka puta ko ngā kaupapa karetao pokanga ka tīmata me te kaha, te ngāwari, me te kaha ki te tatau huringa o te maitai kore waikura, engari ka whakamahia tonu te tungsten i tētahi wāhanga o muri mai o te whanaketanga o te karetao.
I te tīmatanga o te hoahoanga o te karetao, i whakamahia e ngā kaihanga karetao pokanga te maitai kore waikura, engari i muri mai ka whiriwhiria te tungsten nā te mea he pai ake te mahi. Ahakoa te āhua nei he panoni ohorere tēnei i roto i te huarahi whakahaere nekehanga, he whakaahua noa iho. Ko te panoni rauemi he hua o te mahi tahi a te kaihanga karetao me ngā miihini miihini i utua hei hanga i ngā taura.
Kei te noho tonu ngā taura kowiri tira hei mea nui i roto i te mākete taputapu pokanga, inā koa i roto i te mara o ngā taputapu endoscopic. Heoi, ahakoa ka taea e te kowiri tira te tautoko i te nekehanga i roto i ngā tikanga endoscopic/laparoscopic, kāore i te rite te kaha kume ki tōna hoa pakarukaru engari he kikī ake, ā, he kaha ake (e kiia nei ko te tungsten). Ko te hua o te kaha kume.
Ahakoa he pai rawa te tungsten hei whakakapi i te maitai kore waikura hei rauemi taura pai mō ngā karetao pokanga, kāore e taea te mārama ki te hiranga o te mahi tahi pai i waenga i ngā kaihanga taura. Mā te mahi tahi me tētahi miihini taura tino angiangi, ehara i te mea ka whakarite kia hangaia ō taura e ngā kaitohutohu me ngā kaihanga o te ao. Ko te whiriwhiri i te kaihanga taura tika he huarahi tino pono hoki hei whakarite kia whakatairangahia e koe te pūtaiao me te tere o te whakapai ake i te mahere hanga, ka āwhina i a koe ki te whakatutuki i ō whāinga whakahaere nekehanga kia tere ake i ngā kaiwhakataetae e ngana ana ki te whakatutuki i taua mea.
