Ib qho piv txwv ntawm lub tsev kawm ntawv project

Peb muaj ib tug yam ntxwv tsim ntawm lub tsev kawm ntawv project hauj lwm hauv lub quantitative kev txiav txim ntawm ascorbic acid (vitamin C) nyob rau hauv lub tshuaj yej. Cov kev taw qhia tshuaj xyuas qhov tseem ceeb ntawm lub ntsiab lus, yog cov keeb kwm tseeb ntawm txoj kev tshawb kwv.

Ntau Rus siv Txoj kev lis ntshav ntawm rose-tshuaj yej haus thiab raws li cov tshuaj rau ntau yam kab mob. Pom ntawm cov khoom nws ntawm no tshuaj yej yuav muaj nyob rau hauv tej hauj lwm ntawm Lavxias teb sab explorer Peter Alexandrovich Badmaeva. Nws nyob ntau tshaj ib puas xyoo, ua tsaug nyob rau hauv ib feem siv lub Txoj kev lis ntshav ntawm no amazing nroj tsuag.

Ivan-tshuaj yej muaj ib tug tshwj xeeb tshuaj nyob tus yeees, uas yuav pab tau rightly hu ua "pantry xwm." European cov neeg menyuam lub merits ntawm Ivan-tshuaj yej, uas muaj 6.5 lub sij hawm ntau ascorbic acid (vitamin C) tshaj txiv qaub.

By pib ntawm lub XIX xyoo pua, cov khoom no yog tus thib ob nyob rau hauv daim ntawv teev cov xa khoom los ntawm Russia rau teb chaws Europe (tom qab rhubarb). Tom qab lub capture ntawm lub British nyob rau hauv Is Nrias teb nyob rau hauv lub colonized territories tshwm plantations ntawm dub tshuaj yej, ib tug phooj ywg rau koj liking tag nrho cov niaj hnub Russians. Lub British, nrhiav kom tau cov ntaub ntawv uas nreg, "yeej" Russia thiab "kom" ib yam khoom tshiab rau nws cov pej xeem. Maj mam, kev lig kev cai ntawm kev siv ntawm willow-tshuaj ntsuab poob, thiab qhov no pab tau cov khoom tsis ncaj ncees overlooked.

Qhov nyuaj nyiaj txiag teeb meem, lub hom mob kev sib raug zoo nrog European lub teb chaws, tau ua qhov teeb meem ntawm reviving kab lig kev cai ntawm classical Lavxias teb sab tshuaj yej haus txuam nrog rau kev siv ntawm willow-tshuaj ntsuab, qhov tseem ceeb rau lub economic thiab kev nom kev tswv taw tes ntawm view.

Muab cov num ntawm qhov teeb meem, nyob rau hauv cov kev tshawb fawb, peb txiav txim siab los coj ib lub comparative tsom xam ntawm organoleptic thiab tshuaj thaj chaw ntawm willow-tshuaj ntsuab, thiab classic Indian tshuaj yej, qhia lawv zoo sib xws thiab txawv chaw.

Hom phiaj: Yuav kom txiav txim quantitatively cov ntsiab lus ntawm ascorbic acid nyob rau hauv lub pib tshuaj yej kuaj.

Cov hom phiaj ntawm kev ua hauj lwm:

• tshawb lub organoleptic yam ntxwv ntawm qhov kev kuaj npaum li cas los lub tasting;
• ib tug ntau tsom xam ntawm cov ntsiab lus ntawm vitamin C nyob rau hauv qhov kev kuaj los ntawm titration.

Subject ntawm kev tshawb fawb: quantitative cov ntsiab lus ntawm vitamin C nyob rau hauv tus thawj tshuaj yej kuaj.

Lub homphiaj ntawm txoj kev tshawb no: willow-tshuaj ntsuab thiab classic Indian tshuaj yej.

Txoj kev:

• ntaub ntawv kev soj ntsuam;
• iodometry (titrimetric tsom xam);
• Statistical tsom xam ntawm cov kev tshwm sim.

Hypothesis: quantitative cov ntsiab lus ntawm ascorbic acid thiab organoleptic classic Indian tshuaj yej ho ua tsis tau zoo willow-tshuaj yej.

Tom ntej no yog ib tug piav qhia txog qhov tseem ceeb ntawm ascorbic acid yog xaiv cov txheej txheem rau nqa tawm lub xyaum ua tej yam.

Tom qab kawm tiav ntawm txoj kev tshawb tsim cov lus xaus hais txog qhov tseeb thiab feasibility ntawm willow-tshuaj ntsuab raws li ib tug lwm txoj rau lub classic dub tshuaj yej.

xaus

Tsim technology tau ua ib feem ntawm cov niaj hnub kawm ntawv. Lawv yog siv tsis tau tsuas yog nyob rau hauv lub qaum kev kawm ntawv, tab sis kuj nyob rau hauv preschool.

Yuav kom txhua txhua Lavxias teb sab schoolboy muaj lub sij hawm los siv lawv cov tswv yim peev xwm, kis tau txuj ci tshiab, lawv yuav tsum tau muab kev koom tes nyob rau hauv lub tsim thiab kev tshawb fawb kev ua ub no. Yuav ua li cas zoo ntawm peb tes num yog tsis tsim, nyob rau hauv txhua rooj plaub, yuav tsum tau kom xaiv nws kawm, muab lub hom phiaj ntawm txoj kev tshawb, nrhiav tau qhov teeb meem, hypothesis. Txawm nyob rau hauv lub rooj plaub thaum nyob rau hauv lub lag luam nws yuav refuted los yog paub tseeb hais tias nyob rau hauv ib feem, qhov no tsis ploj zuj zus mus qhov tseeb thiab qhov tseem ceeb ntawm cov tsim project. Nyob rau hauv lub nyob ze yav tom ntej yuav ua kom paub kev qauv rau cov xib fwb ntawm Lavxias teb sab. Ib tug ntawm cov khoom nyob rau hauv nws yuav tau nqa tawm kev tshawb fawb nrog cov tub ntxhais kawm, raws li tau zoo raws li kev koom tes ntawm cov hluas tiam nyob rau hauv peb tes num kev ua si.
