Yuav ua li cas yog kaw kaw nyob rau hauv lub system txoj kev xav?
Ib daim ntawv xyoo 1993, General Systems Theory los ntawm David S. Walonick, Ph. D., hais hauv ib feem, 'Lub kaw lus kaw yog ib qho uas muaj kev cuam tshuam tshwm sim ntawm cov kab ke thiab tsis yog nrog ib puag ncig. Lub kaw lus qhib yog ib qho uas tau txais cov tswv yim los ntawm ib puag ncig thiab / lossis tso tawm cov khoom tawm mus rau ib puag ncig
Puas muaj cov kaw lus kaw?
Lub kaw lus kaw tsis muaj nyob hauv qhov xwm txheej Hauv qhov kev txiav txim siab nruj ntawm 'kaw' systems, lawv muaj nyob tsuas yog thaum lawv yog cov txheej txheem tsim, vim tias txhua qhov 'qhov system tiag' lossis 'systems hauv xwm' qhib
Dab tsi yog qhov txawv ntawm qhov kaw kaw thiab qhib qhov system hauv chemistry?
Ib puag ncig yog txhua yam tsis nyob hauv qhov system, uas txhais tau tias tag nrho ntawm lub ntiaj teb. Qhov no yog hu ua qhib qhov system. Yog tias tsuas muaj kev sib pauv cua sov tshwm sim ntawm qhov system thiab nws qhov chaw nyob ib puag ncig nws yog hu ua kaw kaw. Tsis muaj teeb meem tuaj yeem nkag lossis tawm hauv qhov kaw
Nws siv sijhawm ntev npaum li cas rau cov kua qab zib kom tsim tau?
2 rau 4h Raws li txoj cai, nws siv sijhawm ntev npaum li cas rau qab zib kom crystallize? cav 7d Ib yam li ntawd, dab tsi ua rau qab zib crystals tsim? Super-saturated daws tsis ruaj khov, yog li thaum koj nplawm khoom qab zib, qab zib crystals yuav tawm los ntawm kev daws thiab txuas mus rau txoj hlua los yog lo rau hauv lub thawv.
Nws siv sijhawm ntev npaum li cas los tsim lub foob pob atomic?
Lub Laboratory tau tsim nyob rau hauv 1943 raws li qhov chaw Y ntawm Manhattan Project rau ib lub hom phiaj: tsim thiab tsim lub foob pob atomic. Nws tsuas siv 27 lub hlis xwb.
