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 coj ntawm National Institute of Metrology, Suav teb mus xyuas Changping lub hauv paus sim rau kev sib pauv.
Lub Koom Haum National Institute of Metrology, Suav teb tau tsim tsa xyoo 1955, yog ib lub koom haum ntawm Lub Xeev Administration for Market Regulation thiab yog lub chaw tshawb fawb txog kev ntsuas siab tshaj plaws hauv Suav teb thiab yog lub koom haum thev naus laus zis kev cai lij choj hauv xeev. Changping lub hauv paus sim uas tsom mus rau kev tshawb fawb siab heev ntawm kev ntsuas, yog lub hauv paus rau kev tsim kho tshiab ntawm kev tshawb fawb thiab thev naus laus zis, 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 ntawm tog thiab tus lwm thawj coj ntawm Lub Tsev Kawm Ntawv Qib Siab Hauv Tebchaws, Suav teb; Yang Ping, tus thawj coj ntawm lub chaw haujlwm zoo ntawm Lub Tsev Kawm Ntawv Qib Siab Hauv Tebchaws, Suav teb; Yu Lianchao, tus pab cuam ntawm Lub Tsev Kawm Ntawv Tshawb Fawb Txog Kev Npaj Tswv Yim; Yuan Zundong, tus thawj coj ntsuas; Wang Tiejun, tus lwm thawj coj ntawm Lub Tsev Kawm Ntawv Thermal Engineering; Dr. Zhang Jintao, tus neeg saib xyuas National Science thiab Technology Progress Award; Jin Zhijun, tus Tuav Ntaub Ntawv ntawm Pawg Neeg Saib Xyuas Kev Ntsuas Kub; Sun Jianping thiab Hao Xiaopeng, Dr. Thermal Engineering Institute.
Duan Yuning tau qhia txog kev tshawb fawb thiab kev txhim kho kev lag luam thiab kev sib raug zoo ntawm kev pabcuam ntsuas ntawm National Institute of Metrology, Suav teb, thiab tau saib cov yeeb yaj kiab tshaj tawm ntawm National Institute of Metrology, Suav teb.
Thaum peb mus xyuas lub chaw kuaj mob, peb xub mloog Mr. Duan cov lus piav qhia txog "Newton apple tree" nto moo, uas tau nthuav tawm rau National Institute of Metrology, Suav teb los ntawm British National Institute of Physics.
Nyob rau hauv kev coj ntawm Mr. Duan, peb tau mus xyuas boltzmann constant, precision spectroscopy laboratory, quantum metrology laboratory, time-keeping laboratory, medium temperature reference laboratory, infrared remote sensing laboratory, high temperature reference laboratory, thiab lwm yam laboratory. Los ntawm kev piav qhia ntawm txhua tus thawj coj ntawm lub chaw kuaj mob, peb lub tuam txhab muaj kev nkag siab ntxiv txog cov txiaj ntsig kev txhim kho thiab qib thev naus laus zis siab heev ntawm National Institute of Metrology, Suav teb.
Mr. Duan tau qhia peb txog lub chaw kuaj xyuas lub sijhawm, uas suav nrog lub moos cesium atomic fountain uas tsim los ntawm National Institute of Metrology, Suav teb. Raws li lub teb chaws cov peev txheej tseem ceeb, lub sijhawm raug thiab zaus teeb liab cuam tshuam nrog kev ruaj ntseg hauv tebchaws, kev lag luam hauv tebchaws thiab tib neeg txoj kev ua neej. Lub moos Cesium atom fountain, ua lub sijhawm zaus siv tam sim no, yog qhov chaw ntawm lub sijhawm zaus system, uas tso lub hauv paus rau kev tsim lub sijhawm zaus system raug thiab ywj pheej hauv Suav teb.
Thaum tsom mus rau kev txhais dua tshiab ntawm chav ntsuas kub - kelvin, Dr. Zhang jintao, tus kws tshawb fawb ntawm Lub Tsev Kawm Ntawv Thermal Engineering, tau qhia rau peb txog boltzmann constant thiab precision spectroscopy laboratory. Lub chaw kuaj mob tau ua tiav qhov project ntawm "kev tshawb fawb tseem ceeb ntawm kev hloov pauv loj ntawm chav ntsuas kub" thiab tau yeej qhov khoom plig thawj zaug ntawm kev nce qib hauv tebchaws.
Los ntawm kev tsim kho tshiab ntawm cov txheej txheem thiab thev naus laus zis, qhov project tau txais cov txiaj ntsig ntsuas ntawm boltzmann tas li ntawm qhov tsis paub meej 2.0 × 10-6 thiab 2.7 × 10-6, feem, uas yog cov txheej txheem zoo tshaj plaws hauv ntiaj teb. Ntawm ib sab tes, cov txiaj ntsig ntsuas ntawm ob txoj kev tau suav nrog cov nqi pom zoo ntawm cov txheej txheem thoob ntiaj teb ntawm pawg neeg saib xyuas kev tshawb fawb thiab thev naus laus zis (CODATA), thiab siv ua qhov kev txiav txim siab kawg ntawm boltzmann tas li. Ntawm qhov tod tes, lawv yog thawj qhov kev ua tiav hauv ntiaj teb los txais yuav ob txoj hauv kev ywj pheej los ua kom tau raws li kev txhais dua tshiab, ua rau Tuam Tshoj thawj qhov kev koom tes tseem ceeb rau kev txhais cov chav nyob yooj yim ntawm lub kaw lus thoob ntiaj teb ntawm cov chav nyob (SI).
Cov thev naus laus zis tshiab uas tsim los ntawm qhov project no muab kev daws teeb meem rau kev ntsuas qhov kub ntawm lub hauv paus plaub tiam nuclear reactor hauv lub tebchaws qhov project loj, txhim kho qib kev sib kis kub hauv Suav teb, thiab muab kev txhawb nqa kev taug qab kub rau cov teb tseem ceeb xws li kev tiv thaiv tebchaws thiab aerospace. Tib lub sijhawm, nws tseem ceeb heev rau kev paub txog ntau txoj hauv kev siv tshuab, xoom traceability saw, kev ntsuas kub thawj zaug thiab lwm yam thermophysical ntau.
Tom qab kev mus xyuas, Mr. Duan thiab lwm tus tau sib txuas lus nrog cov neeg sawv cev ntawm peb lub tuam txhab hauv chav sib tham. Mr. Duan tau hais tias ua cov tswv cuab ntawm chav ntsuas thev naus laus zis siab tshaj plaws hauv lub tebchaws, lawv txaus siab pab txhawb kev loj hlob ntawm cov tuam txhab thev naus laus zis hauv tebchaws. Xu Jun, Tus Thawj Coj ntawm Pawg Thawj Coj, Zhang Jun, Tus Thawj Coj, thiab He Baojun, tus lwm thawj coj ntawm thev naus laus zis tau hais lawv cov lus ua tsaug rau cov neeg ntawm Lub Tsev Kawm Ntawv Qib Siab Hauv Tebchaws Suav rau lawv qhov kev txais tos. Nrog rau kev txaus siab los txhawb kev koom tes nrog cov neeg ntawm Lub Tsev Kawm Ntawv Qib Siab Hauv Tebchaws Suav, lawv kuj tau hais tias lawv yuav muab lawv cov txiaj ntsig tsim thiab kev tsim khoom sib xyaw nrog cov txiaj ntsig kev siv tshuab ntawm Lub Tsev Kawm Ntawv Qib Siab Hauv Tebchaws Suav, kom ua rau muaj kev pab txhawb rau kev lag luam ntsuas thiab kev txhim kho hauv zej zog.
