Thaum Lub Kaum Hli 23, 2019, peb lub tuam txhab thiab Beijing Electric Albert Electronics Co., Ltd. tau raug caw los ntawm Duan Yuning, tus tuav ntaub ntawv tog thiab tus lwm thawj ntawm National Institute of Metrology, Tuam Tshoj mus xyuas Changping sim puag rau kev sib pauv.
Founded hauv 1955, National Institute of Metrology, Tuam Tshoj yog ib lub koom haum ntawm Lub Xeev Kev Tswj Xyuas Kev Tswj Xyuas Kev Lag Luam thiab yog qhov chaw tshawb fawb txog kev tshawb fawb siab tshaj plaws hauv Suav teb thiab lub xeev-theem kev cai lij choj metrological lub koom haum.Changping sim puag tsom rau kev tshawb fawb qib siab ntawm metrology, yog lub hauv paus rau kev tshawb fawb thiab thev naus laus zis tshiab, kev koom tes thoob ntiaj teb thiab kev cob qhia txuj ci.
Cov neeg tuaj koom lub rooj sib tham feem ntau suav nrog: Duan Yuning, tus tuav ntaub ntawv tog thiab tus lwm thawj ntawm National Institute of Metrology, Tuam Tshoj;Yang Ping, tus thawj coj ntawm kev lag luam zoo department ntawm National Institute of Metrology, Tuam Tshoj; Yu Lianchao, tus pab ntawm lub koom haum tshawb fawb Strategic;Yuan Zundong, tus thawj ntsuas;Wang Tiejun, tus lwm thawj coj ntawm Thermal Engineering Institute; Dr.Zhang Jintao, tus thawj coj ntawm National Science thiab Technology Progress Award; Jin Zhijun, Tus Tuav Ntaub Ntawv ntawm Pawg Kws Tshaj Lij Kub Kub;Sun Jianping thiab Hao Xiaopeng, Dr. Thermal Engineering Institute.
Duan Yuning tau qhia txog kev tshawb fawb txog kev tshawb fawb thiab kev lag luam thiab kev loj hlob ntawm kev pabcuam metrology ntawm National Institute of Metrology, Tuam Tshoj, thiab saib cov yeeb yaj kiab tshaj tawm ntawm National Institute of Metrology, Suav.
Thaum mus xyuas lub chaw kuaj mob, peb xub mloog Mr. Duan cov lus piav qhia ntawm lub npe nrov "Newton apple tree", uas tau nthuav tawm rau National Institute of Metrology, Tuam Tshoj los ntawm British National Institute of Physics.
Raws li kev taw qhia ntawm Mr. Duan, peb tau mus xyuas lub boltzmann tas li, precision spectroscopy laboratory, quantum metrology laboratory, time-keeping laboratory, medium temperature reference laboratory, infrared remote sensing laboratory, high temperature reference laboratory, and other laboratories.Nyob rau hauv- site piav qhia ntawm txhua tus thawj coj hauv chav kuaj, peb lub tuam txhab muaj kev nkag siab ntxiv txog kev txhim kho cov txiaj ntsig thiab qib siab thev naus laus zis ntawm National Institute of Metrology, Suav.
Mr. Duan tau muab peb cov lus qhia tshwj xeeb rau lub sijhawm ntsuas lub sijhawm, uas suav nrog lub moos cesium atomic fountain moos tsim los ntawm National Institute of Metrology, Tuam Tshoj.Raws li lub teb chaws cov peev txheej, muaj tseeb lub sijhawm-zaus teeb liab ntsig txog kev ruaj ntseg hauv tebchaws, kev lag luam hauv tebchaws. thiab tib neeg txoj kev ua neej nyob.Cesium atom fountain moos, raws li lub sij hawm tam sim no siv zaus, yog lub hauv paus ntawm lub sij hawm zaus, uas lays ib tug technical foundation rau kev tsim kho ntawm ib tug raug thiab ywj siab lub sij hawm zaus system nyob rau hauv Tuam Tshoj.
Tsom ntsoov rau qhov kev hloov pauv ntawm chav ntsuas kub - kelvin, Dr. Zhang jintao, tus kws tshawb fawb ntawm Lub Tsev Haujlwm Thermal Engineering, tau qhia rau peb lub boltzmann tas li thiab precision spectroscopy kuaj.Lub chaw soj nstuam tau ua tiav txoj haujlwm ntawm "kev tshawb fawb thev naus laus zis tseem ceeb ntawm kev hloov pauv loj ntawm chav ntsuas kub" thiab tau yeej thawj qhov khoom plig ntawm lub teb chaws kev tshawb fawb thiab thev naus laus zis.
Los ntawm cov txheej txheem tshiab ntawm cov txheej txheem thiab thev naus laus zis, qhov project tau txais kev ntsuas cov txiaj ntsig ntawm boltzmann tsis tu ncua ntawm qhov tsis paub tseeb 2.0 × 10-6 thiab 2.7 × 10-6 feem, uas yog txoj hauv kev zoo tshaj plaws hauv ntiaj teb.Ntawm qhov tod tes, kev ntsuas cov txiaj ntsig ntawm ob txoj hauv kev tau suav nrog cov txiaj ntsig pom zoo ntawm thoob ntiaj teb lub cev lub cev tsis tu ncua ntawm International Commission ntawm cov ntaub ntawv tshawb fawb thiab thev naus laus zis (CODATA), thiab siv los ua qhov kev txiav txim zaum kawg ntawm boltzmann qhov tsis tu ncua.Ntawm qhov tod tes, lawv yog thawj qhov kev ua tiav hauv ntiaj teb los txais yuav ob txoj hauv kev ywj pheej kom tau raws li qhov kev hloov kho tshiab, ua rau Tuam Tshoj thawj qhov tseem ceeb hauv kev txhais cov ntsiab lus ntawm cov txheej txheem thoob ntiaj teb ntawm units (SI).
Cov thev naus laus zis tshiab tsim los ntawm qhov project muab cov kev daws teeb meem rau kev ntsuas ncaj qha ntawm cov tub ntxhais kub ntawm qhov thib plaub-tiam nuclear reactor nyob rau hauv lub teb chaws loj qhov project, txhim kho cov theem ntawm kub tus nqi kis tau tus mob nyob rau hauv Tuam Tshoj, thiab muab kub traceability kev them nyiaj yug rau cov hauj lwm tseem ceeb xws li. raws li lub teb chaws tiv thaiv thiab aerospace.Nyob rau tib lub sijhawm, nws tseem ceeb heev rau kev ua tiav ntawm ntau txoj hauv kev, xoom traceability saw, thawj qhov ntsuas kub thiab lwm yam thermophysical ntau.
Tom qab tuaj xyuas, Mr. Duan thiab lwm tus tau sib tham nrog cov neeg sawv cev ntawm peb lub tuam txhab hauv chav sib tham.Mr. Duan tau hais tias raws li cov tswv cuab ntawm chav ntsuas thev naus laus zis siab tshaj plaws hauv lub tebchaws, lawv txaus siab los pab kev loj hlob ntawm lub teb chaws high-tech lag luam.Xu Jun, Thawj Tswj Hwm ntawm Pawg Thawj Coj, Zhang Jun, Tus Thawj Coj General, thiab He Baojun, tus lwm thawj tswj hwm ntawm thev naus laus zis tau qhia lawv ua tsaug rau cov neeg ntawm National Institute of Metrology, Tuam Tshoj rau lawv txais tos.Nrog rau kev txaus siab los txhawb kev koom tes nrog cov neeg ntawm National Institute of Metrology, Tuam Tshoj, lawv kuj tau hais tias lawv yuav muab lawv cov qauv tsim thiab kev tsim khoom zoo nrog cov txiaj ntsig zoo ntawm National Institute of Metrology, Tuam Tshoj, txhawm rau ua kom muaj txiaj ntsig zoo rau kev lag luam metrology thiab kev loj hlob ntawm kev sib raug zoo.
