Cov kws tshuaj Lavxias zoo ib txwm muaj npe nrov rau lawv txoj kev koom tes rau qhov kev tshawb fawb tsis tu ncua. Tab sis, tej zaum, ib tug ntawm cov tseem ceeb tshaj plaws chemists xws li Alexander Mikhailovich Butlerov thiab Dmitry Ivanovich Mendeleev, uas los ua legendary kws tshawb fawb, thiab niaj hnub no paub tsis tau tsuas yog nyob rau hauv Russia, tab sis thoob plaws lub ntiaj teb no. Hauv peb tsab xov xwm peb yuav tham txog biography thiab kev tshawb fawb ntawm cov neeg zoo.
Alexander Mikhailovich Butlerov: biography
Alexander Butlerov yug hauv thawj ib nrab ntawm lub xyoo pua 19th hauv nroog Chistopol. Vim qhov tseeb tias nws tau tshwm sim hauv tsev neeg ntawm cov tswv av nplua nuj, tus tub hluas tau txais kev kawm zoo. Thaum xub thawj nws kawm hauv ib lub tsev kawm ntawv ntiav, tom qab ntawd hauv gymnasium, tom qab ntawd nws nkag mus hauv tsev kawm ntawv. Txij thaum pib ntawm nws txoj kev kawm hauv tsev kawm ntawv, nws tau xav txog zoology, chemistry thiab botany.
Kev tshawb fawb ntawm Alexander Mikhailovich
Cov kws tshuaj Lavxias zoo li Alexander Mikhailovich Butlerov tau ua haujlwm loj rau kev tshawb fawb. Tom qab kawm tiav hauv tsev kawm ntawv, tus tub hluas txiav txim siab rau nws tus kheej rau kev tshawb fawb thiab tom qab ob peb xyoos dhau los ua tus xibfwb.
Txawm li cas los xij, hauv nws cov hluas, vim nws txoj kev quav tshuaj rau chemistry, Alexander Mikhailovichua siab ntev rau txim. Nws nyiam ua sparklers nrog nws cov phooj ywg, thiab ib zaug txawm los ntawm nws qhov txhaum muaj qhov tawg hauv lub tsev nce. Qhov no yog qhov tshwm sim ntawm ib qho ntawm nws qhov kev sim. Alexander raug txim. Tau ob peb hnub nws sawv hauv chav noj mov kom pom tag nrho, thiab nyob ib ncig ntawm nws lub caj dab dai ib qho kos npe nrog cov yaj saub inscription - "Tus Kws Tshuaj Zoo"
Alexander Mikhailovich Butlerov, zoo li lwm cov kws tshuaj Lavxias teb sab, tau mob siab rau kev kawm txog cov organics. Ntawm nws qhov kev tshawb pom loj tshaj plaws yog kev tsim cov txheej txheem nto moo ntawm cov qauv tshuaj.
YDmitry Ivanovich Mendeleev: biography
Dmitry Mendeleev yug hauv Tobolsk. Txij li thaum yau, nws niam pib pom tias nws tus menyuam yau (thib kaum xya hauv kab), Dimitri, yog ib tug tub hluas uas muaj txiaj ntsig zoo kawg. Txawm li cas los xij, hauv tsev kawm ntawv, nws tsis nyiam chemistry ib zaug - nws nyiam ua lej thiab physics nkaus xwb.
Nyob rau xyoo 1855, Dmitry Ivanovich Mendeleev kawm tiav los ntawm St. Petersburg Main pedagogical lub koom haum, tom qab uas nws heev heev scientific tej hauj lwm, qhia thiab dissertations tam sim ntawd ua raws.
Kev tshawb fawb ntawm Dmitry Ivanovich
Dmitry Ivanovich Mendeleev yog ib tus kws tshawb fawb zoo hauv physics, lej, kev lag luam, huab cua, thiab lwm yam. Tab sis nws txoj kev koom tes rau chemistry tseem ceeb tshwj xeeb. Ntxiv nrog rau qhov tseeb tias tus kws tshawb fawb zoo tau ua ntau yam kev tshawb fawb thiab kev sim, tau sau ntau cov ntawv pov thawj thiab cov ntaub ntawv tshawb fawb, tshawb xyuas cov roj av, kev daws teeb meem, qhia cov tub ntxhais hluas, sau thawj phau ntawv hauv tebchaws Russia - "Fundamentals of Chemistry", nws kujua qhov kev tshawb pom tseem ceeb hauv cheeb tsam no. Nws yog lub sij hawm lub sij hawm ntawm tag nrho cov tshuaj, uas yog, lub npe nrov periodic table.
Ntau tus kws tshuaj Lavxias teb sab tau xav tsis thoob thiab xav tsis thoob los ntawm qhov kev tshawb pom no. Mendeleev tswj tsis tau tsuas yog nkag mus rau tag nrho cov paub cov ntsiab lus tshuaj rau hauv lub rooj, tab sis kuj los twv seb lub hav zoov ntawm cov uas tsis muaj leej twg tau pom. Ua tsaug rau lub sij hawm ntev, nws tau dhau los ua yooj yim dua rau cov menyuam kawm ntawv thiab cov tub ntxhais kawm kawm chemistry, thiab rau cov kws tshawb fawb lawv tus kheej nws yooj yim dua los tsim kev tshawb pom thiab sib piv cov ntaub ntawv.
Mendeleev, tom qab nws tuag, tshuav ntau dua 1500 cov haujlwm tshawb fawb rau tiam. Nyob rau hauv kev hwm ntawm Dmitry Ivanovich, lub 101st tshuaj keeb, mendelevium, tau lub npe.
Alexander Mikhailovich Butlerov thiab Dmitry Ivanovich Mendeleev yog ob tus neeg nyiam heev uas tau mob siab rau lawv lub neej rau kev tshawb fawb thiab ua ntau yam tseem ceeb nrhiav pom. Zoo li txhua tus kws tshuaj Lavxias teb sab zoo, lawv yog cov tshwj xeeb, thiab lawv txoj haujlwm tau kawm hauv tebchaws Lavxias thiab txawv tebchaws.
