Wu Erjing, yug hauv 1933 hauv Baoding, Hebei Xeev, yog tus kws tshawb fawb koom nrog hauv Central South University. Nws qhov kev tshawb fawb tseem ceeb yog cov ntaub ntawv tsis tshua muaj hlau tshiab. Tau txais 19 invention patents, 2 cov qauv siv hluav taws xob, koom nrog cov ntaub ntawv tshiab ntsig txog thev naus laus zis thiab kev tswj hwm rau ntau tshaj 40 xyoo, muaj kev nplua nuj ntawm kev tswj hwm kev lag luam, kev tsim kho qhov project;
Xyoo 1998, thawj pawg ntawm cov khoom siv dav hlau tsim los ntawm xibfwb Wu tau ua haujlwm hauv Central South University. Xib Fwb Wu tau ua ib tug tswv cuab ntawm Tuam Tshoj Tungsten Association Committee. Xyoo 1991, Xib Fwb Wu tau tsim Tuam Tshoj thawj APT (ammonium metatungstate) cog cog hauv Xiamen Chunbao Group, tso lub hauv paus rau kev lag luam ntawm Tuam Tshoj txoj kev lag luam tungsten. Xibfwb Wu hwm kev paub, ntseeg txog kev tshawb fawb thiab thev naus laus zis, muab qhov tseem ceeb rau kev tshawb fawb tshawb fawb, thiab tau tsim kev lag luam-tsev kawm ntawv-kev tshawb fawb kev koom tes nrog Central South University, Hunan University, Lanzhou Institute of Chemical Physics, Suav Academy ntawm Sciences thiab lwm lub tsev kawm ntawv qib siab. Hwa Jing tau cog lus rau lub tuam txhab lub zeem muag ntawm kev ua tus xa khoom tseem ceeb ntawm cov khoom siv hluav taws xob semiconductor rau lub ntiaj teb, thiab yuav ua rau muaj txiaj ntsig zoo rau kev lag luam semiconductor thoob ntiaj teb.
