Nge-23 ka-Okthobha, 2019, inkampani yethu kunye neBeijing Electric Albert Electronics Co., Ltd. bamenywe nguDuan Yuning, unobhala weqela kunye nosekela Mongameli weZiko leSizwe leMetrology, eChina ukuba batyelele isiseko sovavanyo lweChangping ukuze batshintshiselane.
Yasekwa ngo-1955, iZiko leSizwe leMetrology, iTshayina licandelo loLawulo lweLizwe loLawulo lweMarike kwaye lelona ziko liphezulu lophando lwenzululwazi yemetroloji e-China kunye neziko letekhnoloji ye-metrological esemthethweni.Ukutshintsha isiseko sovavanyo kugxininise kuphando oluphambili lwe-metrology, sisiseko senzululwazi neteknoloji entsha, intsebenziswano yamazwe ngamazwe kunye noqeqesho lwetalente.
Abantu abeze kule ntlanganiso ubukhulu becala baquka: uDuan Yuning, unobhala weqela kunye nosekela Mongameli weZiko leSizwe leMetrology, eChina;UYang Ping, umlawuli wesebe lomgangatho weshishini weZiko leSizwe leMetrology, eTshayina; uYu Lianchao, umncedisi weZiko loPhando loBuchule;uYuan Zundong, uMlinganisi oyiNtloko;Wang Tiejun, usekela mlawuli we-Thermal Engineering Institute; uGqr.UZhang Jintao, umntu ophethe iMbasa yeNkqubela yeNzululwazi kunye neTekhnoloji yeSizwe; uJin Zhijun, uNobhala Jikelele weKomiti yoBuchule boMlinganiselo woBuqondo;Sun Jianping kunye noHao Xiaopeng, iGqirha Thermal Engineering Institute.
UDuan Yuning wazisa uphando lwezenzululwazi kunye nophuhliso loqoqosho nentlalo yenkonzo ye-metrology yeZiko leSizwe leMetrology, eTshayina, kwaye wabukela ividiyo yepropaganda yeZiko leSizwe leMetrology, eTshayina.
Ngethuba sityelele ibhubhoratri, saqala ukuphulaphula inkcazo kaMnu. Duan yegama elidumileyo elithi "Newton apple tree", elathi lanikezelwa kwiNational Institute of Metrology, eTshayina yiBritish National Institute of Physics.
Phantsi kwesikhokelo sikaMnu. Duan, sityelele i-boltzmann engaguqukiyo, ilebhu ye-spectroscopy echanekileyo, ilebhu ye-quantum metrology, ilebhu yokugcina ixesha, ilebhu yesalathiso sobushushu obuphakathi, ilebhu ye-infrared evalela kude, ilebhu yereferensi yobushushu obuphezulu, kunye nezinye iilabhoratri. Inkcazo yendawo yenkokeli nganye yelabhoratri, inkampani yethu inokuqonda ngakumbi ngeziphumo zophuhliso oluphezulu kunye nenqanaba letekhnoloji yeZiko leSizwe leMetrology, eChina.
UMnu Duan usinike intshayelelo ekhethekileyo kwilabhoratri yokugcina ixesha, ebandakanya iwotshi yomthombo we-athom ye-cesium ephuhliswe yiNational Institute of Metrology, China.Njengobutyebi bobuchule belizwe, uphawu oluchanekileyo lwexesha-frequency enxulumene nokhuseleko lwesizwe, uqoqosho lwelizwe. kunye nokuphila kwabantu.Iwotshi ye-athomu yeCesium, njengesalathiso sexesha langoku, ngumthombo wenkqubo yefrikhwensi yexesha, ebeka isiseko sobugcisa sokwakhiwa kwenkqubo echanekileyo nezimeleyo yexesha lexesha e-China.
Ugxininise ekuchazeni ngokutsha iyunithi yeqondo lokushisa - kelvin, uDkt Zhang jintao, umphandi we-Institute of thermal Engineering, wazisa kuthi i-boltzmann rhoqo kunye ne-precision spectroscopy laboratory.Ilabhoratri igqibe iprojekthi "yophando lweteknoloji engundoqo kuhlaziyo olukhulu lweyunithi yobushushu" kwaye iphumelele ibhaso lokuqala lenkqubela phambili yesizwe yezenzululwazi kunye nobuchwepheshe.
Ngokusebenzisa uthotho lweendlela ezintsha kunye nobuchwepheshe, iprojekthi ifumene iziphumo zokulinganisa i-boltzmann engaguqukiyo yokungaqiniseki 2.0 × 10-6 kunye ne-2.7 × 10-6 ngokulandelelanayo, ezona ndlela zibalaseleyo kwihlabathi.Kwelinye icala, iziphumo zokulinganisa ezi ndlela zimbini zibandakanyiwe kumaxabiso acetyiswayo ezinto ezisisiseko zezizwe ngezizwe zekhomishini yezizwe ngezizwe yedatha yesayensi nethekhnoloji (CODATA), kwaye isetyenziswa njengesigqibo sokugqibela se-boltzmann's constant.Ngakolunye uhlangothi, ziyimpumelelo yokuqala kwihlabathi ukwamkela iindlela ezimbini ezizimeleyo ukuhlangabezana nokuchazwa ngokutsha, okwenza i-China ibe negalelo elibalulekileyo lokuqala kwinkcazo yeeyunithi ezisisiseko zenkqubo yamazwe ngamazwe yeeyunithi (SI).
Ubugcisa obutsha obuphuhliswe yiprojekthi bubonelela ngesisombululo somlinganiselo othe ngqo wobushushu obungundoqo besizukulwana sesine sesixhobo senyukliya kwiprojekthi enkulu yesizwe, buphucula umgangatho wokudluliselwa kwexabiso lobushushu eTshayina, kwaye lubonelela ngenkxaso yokulandeleka kobushushu kwiinkalo ezibalulekileyo ezifana nezi. njengokhuselo lwesizwe kunye ne-aerospace.Kwangaxeshanye, kubaluleke kakhulu ukufezekiswa kweendlela ezininzi zobugcisa, ikhonkco lokulandela umkhondo elingu-zero, umlinganiselo wokuqala wobushushu kunye nobunye ubuninzi be-thermophysical.
Emva kotyelelo, uMnu. Duan nabanye banxibelelana nabameli benkampani yethu kwigumbi lenkomfa.UMnu. Duan uthe njengamalungu elona candelo liphezulu lobuchwephesha kweli lizwe, bazimisele ukunceda ukukhula kwamashishini kazwelonke akumgangatho ophezulu.UXu Jun, uSihlalo weBhodi, uZhang Jun, uMphathi Jikelele, kunye noHe Baojun, usekela-manejala jikelele wezobuchwepheshe bavakalise umbulelo wabo kubantu beZiko leSizwe leMetrology, eChina ngolwamkelo lwabo.Ngokuzimisela ukomeleza intsebenziswano nabantu beZiko leSizwe leMetrology, eTshayina, bakwavakalise ukuba baya kudibanisa ukuyila kwabo kunye nokuvelisa inzuzo kunye nezibonelelo zobugcisa zeZiko leSizwe leMetrology, eChina, ukuze benze igalelo elifanelekileyo ishishini lemetroloji nophuhliso lwentlalo.
