I te 23 o Oketopa, 2019, i karangatia tā mātou kamupene me Beijing Electric Albert Electronics Co., Ltd. e Duan Yuning, te hēkeretari o te rōpū me te Perehitini Tuarua o te National Institute of Metrology, Haina, kia toro atu ki te turanga whakamātautau o Changping hei whakawhitiwhiti.
I whakatūria i te tau 1955, ko te National Institute of Metrology, Haina he apiti nō te State Administration for Market Regulation, ā, koia te pokapū rangahau pūtaiao metara teitei rawa atu i Haina, he whare hangarau metara ture taumata-ā-rohe hoki. Ko te turanga whakamātautau a Changping e aro ana ki te rangahau matatau o te metara, he turanga mō te auahatanga pūtaiao me te hangarau, te mahi tahi o te ao me te whakangungu taranata.
Ko ngā tāngata i tae atu ki te hui ko: Duan Yuning, te hēkeretari o te rōpū me te Perehitini Tuarua o te National Institute of Metrology, Haina; Yang Ping, te kaiwhakahaere o te tari kounga pakihi o te National Institute of Metrology, Haina; Yu Lianchao, te kaiawhina o te Strategic Research Institute; Yuan Zundong, te kaiwhakahaere matua; Wang Tiejun, te kaiwhakahaere tuarua o te Thermal Engineering Institute; Tākuta Zhang Jintao, te kaiwhakahaere o te National Science and Technology Progress Award; Jin Zhijun, te Hēkeretari Matua o te Komiti Ngaio Ine Mahana; Sun Jianping me Hao Xiaopeng, te Dr. Thermal Engineering Institute.
I whakaurua e Duan Yuning te rangahau pūtaiao me te whanaketanga ōhanga me te pāpori o te ratonga ine ine o te National Institute of Metrology, Haina, ā, i mātaki hoki i te ataata whakatairanga a te National Institute of Metrology, Haina.
I a mātou e toro atu ana ki te taiwhanga, i whakarongo tuatahi mātou ki te whakamārama a Mr. Duan mō te "rākau aporo Newton" rongonui, i tukuna ki te National Institute of Metrology, Haina e te British National Institute of Physics.
I raro i te arataki a Mr. Duan, i toro atu mātou ki te taiwhanga pūmau boltzmann, te taiwhanga irahiko tino tika, te taiwhanga ine irahiko, te taiwhanga pupuri wā, te taiwhanga tohutoro pāmahana waenga, te taiwhanga pūoko mamao infrared, te taiwhanga tohutoro pāmahana teitei, me ētahi atu taiwhanga. Mā te whakamārama a ia kaiārahi taiwhanga i te papaanga, kua mārama ake tā mātou kamupene ki ngā hua whanaketanga matatau me te taumata hangarau matatau o te National Institute of Metrology, Haina.
I homai e Mr. Duan he whakataki motuhake ki te taiwhanga pupuri wā, tae atu ki te karaka puna atomika cesium i whakawhanakehia e te National Institute of Metrology, Haina. Hei rauemi rautaki a te whenua, he tohu auau-wā tika e pā ana ki te haumarutanga ā-motu, te ōhanga ā-motu me te oranga o te tangata. Ko te karaka puna atomika cesium, hei tohutoro auau wā o nāianei, te pūtake o te pūnaha auau wā, e whakatakoto ana i te turanga hangarau mō te hanganga o tētahi pūnaha auau wā tika me te motuhake i Haina.
I te arotahi ki te whakamāramatanga anō o te waeine pāmahana — Kelvin, i whakauru mai a Tākuta Zhang Jintao, he kairangahau nō te Institute of Thermal Engineering, i te taiwhanga tirotiro pūmau me te tika o Boltzmann. Kua oti i te taiwhanga te kaupapa "rangahau hangarau matua mō te whakahoutanga nui o te waeine pāmahana" ā, kua toa i te tohu tuatahi o te ahunga whakamua pūtaiao me te hangarau ā-motu.
Nā roto i te raupapa o ngā tikanga me ngā hangarau auaha, i whiwhi te kaupapa i ngā hua ine o te pūmau Boltzmann o te koretake 2.0×10-6 me 2.7×10-6, koinei ngā tikanga pai rawa atu o te ao. I tētahi taha, i whakaurua ngā hua ine o ngā tikanga e rua ki roto i ngā uara e taunakitia ana o ngā pūmau ā-tinana taketake o te ao o te komihana o te ao mō ngā raraunga pūtaiao me te hangarau (CODATA), ā, e whakamahia ana hei whakatau whakamutunga mō te pūmau Boltzmann. I tētahi atu taha, koinei te whakatutukitanga tuatahi o te ao ki te tango i ngā tikanga motuhake e rua hei whakatutuki i te whakamāramatanga anō, ka waiho ko te takoha nui tuatahi a Haina ki te whakamāramatanga o ngā waeine taketake o te pūnaha waeine o te ao (SI).
Mā te hangarau auaha i whakawhanakehia e te kaupapa nei ka whakaratohia he otinga mō te ine tika i te pāmahana matua o te tauhohenga karihi o te whakatupuranga tuawhā i roto i te kaupapa nui ā-motu, ka whakapai ake i te taumata tuku uara pāmahana i Haina, ā, ka tautoko i te whai i te pāmahana mō ngā mara nui pēnei i te tiaki whenua me te rererangi. I taua wā anō, he mea nui rawa atu mō te whakatinanatanga o ngā huarahi hangarau maha, te mekameka whai kore, te ine tuatahi i te pāmahana me ētahi atu rahinga wera-tinana.
I muri i te haerenga mai, i kōrero a Mr. Duan me ētahi atu ki ngā māngai o tā mātou kamupene i roto i te rūma hui. I kī a Mr. Duan, hei mema mō te wāhanga hangarau ine teitei rawa atu o te motu, e hiahia ana rātou ki te āwhina i te tipu o ngā umanga hangarau teitei ā-motu. I whakapuaki a Xu Jun, Tiamana o te Poari, a Zhang Jun, Kaiwhakahaere Matua, me He Baojun, kaiwhakahaere matua tuarua o te hangarau i ō rātou mihi ki te iwi o te National Institute of Metrology, Haina mō tā rātou manaaki. I te hiahia ki te whakapakari i te mahi tahi me te iwi o te National Institute of Metrology, Haina, i whakapuaki hoki rātou ka whakakotahi i ō rātou painga hoahoa me te hanga me ngā painga hangarau o te National Institute of Metrology, Haina, kia taea ai te whai wāhi tika ki te umanga ine me te whanaketanga hapori.
