Xyoob, feem ntau hu ua "cov hlau ntawm xwm," tab tom nrov zuj zus ua cov khoom siv hauv tsev uas ruaj khov. Nrog nws txoj kev loj hlob sai, kev phooj ywg rau ib puag ncig, thiab lub zog zoo kawg nkaus, xyoob yog lwm txoj hauv kev zoo rau cov khoom siv hauv tsev xws li pob zeb thiab hlau. Ib qho ntawm cov yam ntxwv tseem ceeb uas ua rau xyoob nyiam heev yog nws lub zog compressive, uas hais txog nws lub peev xwm los tiv taus cov khoom thauj yam tsis muaj kev tawg. Tsab xov xwm no delves rau hauv lub zog compressive ntawm xyoob thiab kev txhim kho tas mus li hauv nws cov txheej txheem uas txhim kho nws cov kev ua tau zoo hauv ntau yam kev siv.
Lub Zog Compressive ntawm Xyoob
Xyoob cov yam ntxwv ntawm cov qauv yog qhov tshwj xeeb, tshwj xeeb tshaj yog nws lub zog compressive. Kev tshawb fawb tau qhia tias xyoob muaj lub zog compressive zoo ib yam li cov pob zeb ua vaj tse, ua rau nws yog ib qho kev sib tw muaj zog rau kev siv hauv cov qauv thauj khoom. Piv txwv li, Phyllostachys edulis, feem ntau hu ua Moso xyoob, muaj lub zog compressive ntawm kwv yees li 40-50 MPa, uas ze rau lub zog compressive ntawm qee hom pob zeb ua vaj tse. Lub zog compressive siab no yog vim muaj cov khoom sib xyaw tshwj xeeb ntawm cov xyoob fibers, uas tau ntim thiab taw qhia rau hauv txoj hauv kev uas muab kev txhawb nqa zoo heev hauv qab kev nyuaj siab.
Txawm li cas los xij, lub zog ntawm xyoob tuaj yeem sib txawv nyob ntawm ntau yam, suav nrog hom xyoob, hnub nyoog, cov dej noo, thiab cov xwm txheej uas nws raug sau thiab ua tiav. Yog li ntawd, kev nkag siab thiab kev txhim kho cov yam no yog qhov tseem ceeb rau kev ua kom cov khoom siv ua tau zoo tshaj plaws hauv kev tsim kho thiab lwm yam kev siv.
Kev Txhim Kho Cov Txheej Txheem Hauv Kev Tsim Khoom Xyoob
Cov kev nce qib tsis ntev los no hauv kev ua cov xyoob tau txhim kho nws cov qauv zoo thiab nthuav dav nws daim ntawv thov hauv kev tsim kho. Ib qho tseem ceeb yog kev kho thiab khaws cia xyoob kom txhim kho nws lub zog compressive. Cov txheej txheem ib txwm muaj, xws li kev ziab thiab kev kho tshuaj, tau raug kho kom zoo kom ntseeg tau tias xyoob tseem muaj zog thiab ruaj khov dhau sijhawm.
Piv txwv li, cov kws tshawb fawb tau tsim cov txheej txheem los txo cov dej noo ntawm xyoob kom zoo dua, vim tias cov dej noo ntau dhau tuaj yeem ua rau nws lub zog compressive tsis muaj zog. Tsis tas li ntawd, kev tsim kho tshiab hauv lamination thiab cov khoom siv xyoob sib xyaw ua ke tau ua rau muaj cov khoom uas muab lub zog ntuj ntawm xyoob nrog kev tiv thaiv zoo dua rau cov yam ntxwv ib puag ncig.
Lwm qhov kev txhim kho tseem ceeb yog cov txheej txheem sib koom ua ke thiab kev sib txuas uas siv rau hauv kev tsim cov xyoob. Cov txheej txheem tsim kho niaj hnub no tau ua rau muaj kev txhim kho ntawm kev sib txuas muaj zog thiab txhim khu kev qha dua ntawm cov khoom xyoob, uas ua rau lub zog thiab kev ruaj khov ntawm cov qauv xyoob zoo dua.
Cov Ntawv Thov thiab Kev Cia Siab Yav Tom Ntej
Lub zog ntawm xyoob uas zoo dua qub, ua ke nrog cov txheej txheem tshiab, tau qhib ntau txoj hauv kev rau nws siv hauv kev tsim kho. Xyoob tam sim no tau siv rau txhua yam los ntawm cov tsev nyob mus rau cov haujlwm loj hauv kev tsim kho vaj tse. Piv txwv li, xyoob tau siv los tsim cov choj, pavilions, thiab txawm tias cov tsev ntau txheej hauv Es Xias, qhia txog nws lub peev xwm ua cov khoom siv tseem ceeb hauv kev tsim kho.
Raws li qhov kev thov rau cov ntaub ntawv ruaj khov txuas ntxiv mus, qhov kev tsom mus rau kev txhim kho xyoob lub zog compressive thiab cov txheej txheem tsim khoom yuav nce ntxiv. Kev tshawb fawb yav tom ntej yuav tshawb nrhiav kev siv nanotechnology, cov khoom sib xyaw ua ke, thiab lwm yam txheej txheem txiav tshiab los txhim kho xyoob cov khoom, ua rau nws yog qhov kev xaiv zoo dua rau kev tsim kho uas tsis muaj kuab paug rau ib puag ncig.
Xyoob lub zog compressive, ua ke nrog kev txhim kho cov txheej txheem tsis ntev los no, qhia txog nws lub peev xwm ua cov khoom siv hauv tsev uas ruaj khov. Nrog kev tshawb fawb thiab kev nce qib ntawm thev naus laus zis, cov khoom xyoob tau npaj los ua lub luag haujlwm tseem ceeb rau yav tom ntej ntawm kev tsim kho ntsuab. Los ntawm kev txuas ntxiv txhim kho cov txheej txheem uas txhim kho cov khoom siv ntawm xyoob, cov khoom siv tuaj yeem ua tau raws li qhov xav tau ntawm cov qauv niaj hnub thaum tswj hwm nws cov txiaj ntsig zoo rau ib puag ncig.
