Ma ʻOkakopa 23, 2019, ua kono ʻia kā mākou hui a me Beijing Electric Albert Electronics Co., Ltd. e Duan Yuning, ke kākau ʻōlelo pāʻina a me ka Hope Pelekikena o National Institute of Metrology, Kina e kipa aku i Changping hoʻokolohua kumu no ka hoʻololi.
ʻIke ʻia i ka makahiki 1955, ʻo ka National Institute of Metrology, Kina he lālā o ka State Administration for Market Regulation a ʻo ia ke kikowaena noiʻi ʻepekema metrological kiʻekiʻe loa ma Kina a me kahi keʻena ʻenehana metrological kānāwai kiʻekiʻe.ʻO Changping hoʻokolohua kumu e kālele ana i ka noiʻi kiʻekiʻe o ka metrology, he kumu ia no ka ʻepekema a me ka ʻenehana hou, ka hui honua a me ka hoʻomaʻamaʻa talena.
ʻO ka poʻe e hele ana i ka hālāwai, ʻo ia hoʻi: Duan Yuning, ke kākau ʻōlelo a me ka hope Pelekikena o ka National Institute of Metrology, Kina;ʻO Yang Ping, ke alakaʻi o ka ʻoihana ʻoihana maikaʻi o ka National Institute of Metrology, Kina; Yu Lianchao, ke kōkua o ka Strategic Research Institute;Yuan Zundong, ka Luna Nui;ʻO Wang Tiejun, ka luna hoʻomalu o ka Thermal Engineering Institute; Dr.ʻO Zhang Jintao, ka mea nāna e mālama i ka makana ʻepekema a me ʻenehana no ka holomua ʻana;ʻO Sun Jianping lāua ʻo Hao Xiaopeng, ka Dr. Thermal Engineering Institute.
Ua hoʻolauna ʻo Duan Yuning i ka noiʻi ʻepekema a me ka hoʻomohala waiwai a me ka hoʻomohala ʻana o ka lawelawe metrology o National Institute of Metrology, Kina, a nānā i ka wikiō propaganda o National Institute of Metrology, Kina.
I ko mākou kipa ʻana i ka hale hana, ua hoʻolohe mua mākou i ka wehewehe ʻana a Mr. Duan no ka "Newton apple tree" kaulana, i hōʻike ʻia i ka National Institute of Metrology, Kina e ka British National Institute of Physics.
Ma lalo o ke alakaʻi ʻana a Mr. Duan, ua kipa mākou i ka boltzmann mau, precision spectroscopy laboratory, quantum metrology laboratory, time-keeping laboratory, medium temperature reference laboratory, infrared remote sensing laboratory, high temperature reference laboratory, a me nā laboratories.Through the on- ʻO ka wehewehe ʻana o ka paena o kēlā me kēia alakaʻi ʻoihana, ua ʻike hou kā mākou hui i nā hopena hoʻomohala holomua a me ka pae ʻenehana kiʻekiʻe o National Institute of Metrology, Kina.
Ua hāʻawi mai ʻo Mr. Duan iā mākou i kahi hoʻolauna kūikawā i ke keʻena mālama manawa, ʻo ia hoʻi ka uaki puna cesium atomic i hoʻomohala ʻia e ka National Institute of Metrology, Kina. Ma ke ʻano he kumu waiwai o ka ʻāina, ka hōʻailona manawa manawa kūpono e pili ana i ka palekana aupuni, ka hoʻokele waiwai aupuni. a me ke ola o kanaka.Cesium atom punawai clock, e like me ka manawa o ka manawa pinepine kuhikuhi, i ke kumu o ka manawa pinepine nenoaiu, e waiho ana i ke kumu oaoieei no ke kukulu ana i ka pololei a me ke kūʻokoʻa manawa pinepine nenoaiu ma Kina.
Ke kālele 'ana ma luna o ka redefinition o ke ana wela - kelvin, Dr. Zhang jintao, he mea noiʻi o ka Institute of Thermal 'enekinia, i hoʻolauna mai iā mākou i ka boltzmann mau a me ka precision spectroscopy hale hana.Ua hoʻopau ke keʻena hana i ka papahana o "ka noiʻi ʻenehana nui ma ka hoʻoponopono nui o ka ʻāpana wela" a ua lanakila i ka makana mua o ka holomua ʻepekema a me ka ʻenehana.
Ma o nā ʻano hana hou o nā ʻano a me nā ʻenehana, ua loaʻa i ka papahana nā hopena ana o ka boltzmann mau o ka maopopo ʻole 2.0 × 10-6 a me 2.7 × 10-6, ʻo ia nā ala maikaʻi loa o ka honua.Ma kekahi ʻaoʻao, ua hoʻokomo ʻia nā hopena ana ʻana o nā ʻano ʻelua i loko o nā waiwai i manaʻo ʻia o nā ʻano kūlohelohe kumu honua o ke komisina honua no ka ʻikepili ʻepekema a me ka ʻenehana (CODATA), a ua hoʻohana ʻia ʻo ia ka hoʻoholo hope loa o ka mau o boltzmann.Ma ka ʻaoʻao ʻē aʻe, ʻo lākou ka mea mua i hoʻokō i ka honua e lawe i ʻelua mau ala kūʻokoʻa e hoʻokō ai i ka wehewehe hou ʻana, e hana ana i ka hāʻawi nui mua o Kina i ka wehewehe ʻana i nā ʻāpana kumu o ka ʻōnaehana honua o nā ʻāpana (SI).
ʻO ka ʻenehana hou i hoʻomohala ʻia e ka papahana e hāʻawi i kahi hopena no ke ana pololei ʻana i ke ana wela o ka reactor nuklea eha-hanauna ma ka papahana nui aupuni, hoʻomaikaʻi i ke kiʻekiʻe o ka lawe ʻana i ka waiwai wela ma Kina, a hāʻawi i ke kākoʻo traceability wela no nā māla koʻikoʻi. e like me ka pale aupuni a me ka aerospace.Ma ka manawa like, he mea koʻikoʻi ia no ka hoʻokō ʻana i nā ala ʻenehana he nui, ke kaulahao traceability zero, ke ana mua o ka mahana a me nā nui thermophysical ʻē aʻe.
Ma hope o ka mākaʻikaʻi ʻana, ua kamaʻilio ʻo Mr. Duan a me nā mea ʻē aʻe me nā ʻelele o kā mākou hui ma ka lumi hālāwai.Ua ʻōlelo ʻo Mr. Duan, ma ke ʻano he lālā o ka ʻenehana ana ʻenehana kiʻekiʻe loa ma ka ʻāina, ua mākaukau lākou e kōkua i ka ulu ʻana o nā ʻoihana ʻenehana kiʻekiʻe.Ua hōʻike aku ʻo Xu Jun, Luna Hoʻomalu o ka Papa, ʻo Zhang Jun, Luna Nui, a me He Baojun, hope manakia o ka ʻenehana i ko lākou mahalo i ka poʻe o ka National Institute of Metrology, Kina no ko lākou hoʻokipa ʻana.Me ka makemake e hoʻoikaika i ka launa pū ʻana me ka poʻe o ka National Institute of Metrology, Kina, ua hōʻike pū lākou e hui pū lākou i kā lākou hoʻolālā a me nā pono hana hana me nā pono ʻenehana o ka National Institute of Metrology, Kina, i mea e hāʻawi ai i nā haʻawina kūpono i ka ʻoihana metrology a me ka hoʻomohala pilikanaka.
Ka manawa hoʻouna: Sep-21-2022
