Booqashada Saldhigga Tijaabada ee Chang Ping ee Machadka Qaranka ee Cilmiga Cilmiga, Shiinaha

Oktoobar 23, 2019, shirkadeena iyo Beijing Electric Albert Electronics Co., Ltd. waxaa lagu martiqaaday Duan Yung, xoghayaha xisbiga iyo kuxigeenka Machadka Qaranka ee Metrology, Shiinaha si ay u booqdaan saldhigga tijaabada Changping ee beddelka.

Waxaa la aasaasay 1955, Machadka Qaranka ee Metrology, Shiinaha waa qayb ka mid ah Maamulka Gobolka ee Xeerarka Suuqa waana xarunta ugu sareysa cilmi-baarista sayniska ee Shiinaha iyo machad tignoolajiyada heer-goboleed ee sharciga ah.Beddelidda saldhigga tijaabada ah ee diiradda saaraya cilmi-baarista sare ee metrology, waa saldhigga hal-abuurka sayniska iyo tignoolajiyada, iskaashiga caalamiga ah iyo tababarka kartida.

Dadka ka soo qayb galay kulanka ayaa waxaa ka mid ahaa: Duan Yuning, xoghayaha xisbiga iyo madaxweyne ku xigeenka machadka qaran ee metrology, Shiinaha;Yang Ping, oo ah agaasimaha waaxda tayada ganacsiga ee Machadka Qaranka ee Cilmi-baarista, Shiinaha, Yu Lianchao, kaaliyaha Machadka Cilmi-baarista Istaraatiijiga;Yuan Zundong, madaxa cabbiraadaha;Wang Tiejun, agaasime ku xigeenka Machadka Thermal Engineering; Dr.Zhang Jintao, qofka mas'uulka ka ah Abaalmarinta Horumarka Sayniska iyo Tignoolajiyada Qaranka;Jin Zhijun, Xoghayaha Guud ee Guddiga Xirfadlayaasha Qiyaasta Heerkulka;Sun Jianping iyo Hao Xiaopeng, Dr. Thermal Engineering Institute.

Duan Yuning wuxuu soo bandhigay cilmi-baarista sayniska iyo horumarinta dhaqaalaha iyo bulshada ee adeegga metrology ee Machadka Qaranka ee Metrology, Shiinaha, wuxuuna daawaday fiidiyowga dacaayadda ee Machadka Qaranka ee Metrology, Shiinaha.

Markii aan booqanay shaybaarka, waxaan ugu horeyn dhageysanay sharaxaadda Mr. Duan ee ku saabsan geedka tufaaxa ee caanka ah ee Newton, kaas oo uu u soo bandhigay Machadka Qaranka ee Metrology, Shiinaha Machadka Qaranka ee Fiisigiska ee Ingiriiska.

Iyada oo uu hagayo Mr. Duan, waxaanu booqanay boltzmann joogto ah, shaybaadhka spectroscopy saxda ah, shaybaadhka metrology quantum, shaybaadhka ilaalinta wakhtiga, shaybaadhka tixraaca heerkulka dhexdhexaadka ah, shaybaadhka dareenka fog ee infrared, shaybaadhka tixraaca heerkulka sare, iyo shaybaadhka kale. Sharaxaada goobta ee hogaamiye shaybaadhka kasta, shirkadeena waxay leedahay faham faahfaahsan oo dheeraad ah oo ku saabsan natiijooyinka horumarka horumarsan iyo heerka tignoolajiyada horumarsan ee Machadka Qaranka ee Metrology, Shiinaha.

Mr. Duan wuxuu na siiyay horudhac gaar ah oo ku saabsan shaybaarka ilaalinta waqtiga, kaas oo ay ku jiraan saacada cesium atomic fountain clock oo uu sameeyay Machadka Qaranka ee Metrology, Shiinaha. Sida ilaha istiraatijiyadeed ee waddan, calaamad sax ah waqti-soo noqnoqoshada oo la xidhiidha amniga qaranka, dhaqaalaha qaranka. iyo hab-nololeedka dadka.Cesium atamka isha, oo ah tixraaca soo noqnoqda wakhtiga hadda, waa isha nidaamka soo noqnoqda wakhtiga, kaas oo dhigaya aasaas farsamo oo loogu talagalay dhismaha nidaamka soo noqnoqda wakhtiga saxda ah oo madaxbannaan ee Shiinaha.

Diirada saarida dib-u-qeexinta cutubka heerkulka - kelvin, Dr. Zhang jintao, oo ah cilmi-baare ka tirsan Machadka Thermal Engineering, ayaa noo soo bandhigay boltzmann joogto ah iyo shaybaarka spectroscopy saxda ah.Shaybaadhka ayaa dhamaystiray mashruuca "cilmi baarista tignoolajiyada muhiimka ah ee dib u habaynta weyn ee unugga heerkulka" wuxuuna ku guuleystay abaal-marintii ugu horreysay ee horumarka sayniska iyo tignoolajiyada qaranka.

Iyada oo taxane ah oo hal-abuurnimo hababka iyo teknoolajiyada, mashruuca helay natiijada cabbiraadda boltzmann joogto ah hubin la'aanta 2.0 × 10-6 iyo 2.7 × 10-6, siday u kala horreeyaan, kuwaas oo ahaa hababka ugu fiican adduunka.Dhinaca kale, natiijooyinka cabbirka ee labada hab ayaa lagu daray qiyamka lagu taliyey ee joogtada ah ee asaasiga ah ee caalamiga ah ee guddiga caalamiga ah ee xogta sayniska iyo tignoolajiyada (CODATA), waxaana loo isticmaalaa go'aaminta kama dambaysta ah ee joogtada ah ee boltzmann.Dhanka kale, waa guushii ugu horreysay ee adduunka si ay u qaataan laba hab oo madaxbannaan si ay u daboolaan dib-u-qeexinta, taas oo ka dhigaysa kaalintii ugu horreysay ee Shiinaha ee qeexidda unugyada aasaasiga ah ee nidaamka caalamiga ah ee unugyada (SI).

Tiknoolajiyada hal-abuurka leh ee uu sameeyay mashruucu wuxuu bixiyaa xal loogu talagalay cabbirka tooska ah ee heerkulka asaasiga ah ee jiilka afraad ee nukliyeerka mashruuca weyn ee qaranka, wuxuu hagaajiyaa heerka gudbinta qiimaha heerkulka Shiinaha, wuxuuna bixiyaa taageerada raadinta heerkulka ee meelaha muhiimka ah sida sida difaaca qaranka iyo hawada sare.Isla mar ahaantaana, waxay muhiimad weyn u leedahay xaqiijinta habab badan oo farsamo, silsiladda raadraaca eber, cabbirka aasaasiga ah ee heerkulka iyo cabbirrada kale ee heerkulbeegga.

Booqashada ka dib, Mr. Duan iyo kuwa kale waxay la xiriireen wakiilada shirkadeena ee qolka shirarka.Mr. Duan waxa uu sheegay in iyaga oo ah xubnaha qaybta ugu saraysa tignoolajiyada cabbiraadda ee dalka ay diyaar u yihiin in ay gacan ka geystaan ​​kobaca shirkadaha teknoolajiyada sare ee qaranka.Xu Jun, Guddoomiyaha Guddiga, Zhang Jun, Maareeyaha Guud, iyo He Baojun, maareeyaha guud ee tiknoolajiyada ayaa muujiyay sida ay ugu mahadcelinayaan dadka Machadka Qaranka ee Metrology, Shiinaha soo dhawayntooda.Iyadoo rabitaanka lagu xoojinayo wadashaqeynta dadka ku nool Machadka Qaranka ee Metrology, Shiinaha, waxay sidoo kale muujiyeen inay isku dari doonaan faa'iidooyinka naqshadeynta iyo wax soo saarka iyo faa'iidooyinka farsamada ee Machadka Qaranka ee Metrology, Shiinaha, si ay u sameeyaan tabarucaad ku habboon warshadaha metrology iyo horumarinta bulshada.
