Zoo tias cov me nyuam niaj hnub no tsis xav tsis thoob li. Newfangled gadgets, cov khoom ua si uas muaj ntau lub zog sib txawv ntawm cov uas lawv niam lawv txiv muaj thaum yau, zoo li lub nkoj niaj hnub los ntawm lub nkoj ntoo.
Tab sis tsis ntev los no, cov niam txiv tau them nyiaj ntau dua rau qhov no lossis qhov kev ua si ntawd muab rau kev txhim kho. Ib txhia ntawm lawv tso cai rau koj los tshawb txog lub ntiaj teb, tsim cov me nyuam lub hlwb thiab lub cev.
Thiab yog tias, ntxiv rau, qhov kev ua si no tuaj yeem ua rau nws tus kheej nrog kev koom tes ntawm tus menyuam, ces qhov no yog qhov ntxiv. Hauv Internet, koj tuaj yeem pom ntau yam khoom ua si. Ib qho yooj yim thiab nthuav tshaj plaws yog cov kua uas tsis yog-Newtonian. Yog li cas koj ua cov kua dej tsis-Newtonian hauv tsev thiab koj xav tau dab tsi?
Dab tsi yog cov kua dej tsis-Newtonian
Ua ntej mus rau lo lus teb rau lo lus nug: "Yuav ua li cas ua kom cov kua dej tsis-Newtonian hauv tsev nrog koj tus kheej txhais tes?" - nws yuav tsis yog superfluous to taub nws yog dab tsi thiab nws ua haujlwm li cas.
Non-Newtonian kua yog ib yam khoom uas coj txawv txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm kev ua haujlwm ntawm nws. Yog hais tias qhov ceev ntawm sab nraud cuam tshuam rau nws me me, ces nws qhia tau hais tias ib tug zoo tib yam kua. Thiab yog tias nws tau ua raws li qhov nrawm dua, ces nws zoo ib yam hauv cov yam ntxwv rau lub cev muaj zog.
Qhov zoo ntawm qhov kev ua si lom zem xws li:
- Muaj peev xwm thiab yooj yim ntawm tus kheej tsim tawm.
- Tus nqi qis thiab muaj cov khoom xyaw.
- Kev paub txog lub sijhawm rau menyuam yaus.
- Sustainable (tsis zoo li qee qhov kev ua si yas, nws tsis muaj cov tshuaj phem, thiab muaj pes tsawg leeg paub rau koj ua ntej).
Fun & Education
Dab tsi yuav zoo dua li ua tej yam ntxim nyiam thiab txawv txawv rau koj tus menyuam? Ntxiv mus, zaj lus qhia no yuav muaj txiaj ntsig tiag tiag tsis yog rau cov menyuam yaus xwb, tab sis kuj rau cov neeg laus. Qhov yooj yim ntawm yuav ua li cas ua cov kua dej uas tsis yog Newtonian hauv tsev tso cai rau koj los tsim kev lom zem lom zem hauv ob peb feeb xwb. Qhov tshwm sim yog qhov kev ua si uas yuav txaus siab rau tag nrho tsev neeg. Tsis tas li ntawd, nws txhim kho kev txawj tsav tsheb hauv cov menyuam yaus.
Yog tias koj ntaus cov kua dej uas tsis yog Newtonian sai, nws yuav coj zoo li lub cev khov thiab koj yuav hnov nws elasticity. Yog tias koj maj mam txo koj txhais tes rau hauv nws, ces nws yuav tsis ntsib teeb meem, thiab yuav muaj kev xav tias nws yog dej.
Lwm qhov zoo yog kev txhim kho ntawm kev xav. Nrog rau ntau hom kev cuam tshuam rau cov kua, nws coj tau zoo heev. Yog tias koj muab lub thawv nrog rau ntawm qhov chaw vibrating lossis tsuas yog co nws sai sai, ces nws pib siv sijhawm ntev heev. Cov duab txawv txawv.
Tsis txhob hnov qab cov txiaj ntsig kev kawm thiab. Xws li cov kua tso cai rau hauv kev xyaum los kawm txog lub hauv paus yooj yim ntawm physics - cov khoom ntawm lub cev thiab kua.
Yuav ua li cas thiaj ua kua tsis-Newtonian hauv tsev: ob txoj hauv kev
Cov khoom sib xyaw ua ke ncaj qha cuam tshuam rau nws cov khoom. Yog li, ib tug yuav tsum paub yuav ua li cas ua ib tug tsis-Newtonian kua nyob rau hauv tsev. Daim ntawv qhia yog yooj yim heev. Nws tsuas muaj ob yam khoom xyaw tseem ceeb - dej thiab hmoov txhuv nplej siab. Cov khoom xyaw kawg tuaj yeem yog pob kws lossis qos yaj ywm. Cov dej yuav tsum txias. Txhua yam yog sib xyaw kom zoo. Txhua yam yog npaj txhij!
Y Rau ntau lub xeev ntawm cov dej sib tov, qhov feem ntawm dej thiab hmoov txhuv nplej siab yog noj 1: 1. Rau kev nyuaj - 1: 2. Yog xav tau, koj tuaj yeem ntxiv xim xim rau nws, ces qhov sib tov yuav ci.
Thiab yuav ua li cas thiaj ua kua tsis-Newtonian hauv tsev yam tsis muaj hmoov txhuv nplej siab? Daim ntawv qhia no yog qhov nyuaj me ntsis, tab sis tsuas yog siv tau zoo li yav dhau los. Ua ntej, dej thiab zoo tib yam PVA kua nplaum yog sib xyaw ua ke ntawm 0.75: 1. Cais, dej yog ua ke nrog me me ntawm borax. Tom qab ntawd, ob qho tib si sib xyaw thiab sib xyaw kom zoo.
Ob txoj hauv kev tsim cov kua dej tsis yog Newtonian, tab sis thawj zaug yog qhov yooj yim dua thiab nrov tshaj plaws.
Ntau dej thiab hmoov nplej…
Kev paub yuav ua li cas ua cov kua dej uas tsis yog-Newtonian hauv tsev, koj tuaj yeem, los ntawm kev nce cov proportions,ua kom ib tug txaus tus nqi ntawm xws li ib tug sib tov thiab sau nrog, piv txwv li, me me pas dej ua ke. Qhov tob ntawm 15-25 centimeters yuav txaus. Tom qab ntawd koj tuaj yeem dhia, khiav, seev cev ntawm cov kua dej no yam tsis tau poob. Tab sis yog tias koj nres, koj tam sim ntawd poob rau hauv nws. Qhov no lom zem heev rau cov laus thiab menyuam yaus.
Hauv Malaysia, tag nrho lub pas dej da dej tau ntim nrog cov kua dej uas tsis yog-Newtonian. Qhov chaw no tam sim ntawd tau nrov heev. Cov neeg muaj hnub nyoog muaj kev lom zem nyob ntawd.
