Kev hloov pauv hloov pauv yog qhov tib lub cev tshwm sim raws li kev hloov pauv ntawm lub zog ntxiv. Nyob rau hauv ob qho tib si, cov hlau quab yuam yog pauv mus rau lub pob zeb los ntawm kev sib zog ua haujlwm uas tau qhib los ntawm cov ntawv hlais ntawm qhov sib cuam tshuam.
Dab tsi yog hloov pauv hauv cov pob zeb ua kom muaj zog?
Nyob rau hauv cov tswvcuab pretensioned lub prestressing quab yuam yog hloov los ntawm cov xov hlau los yog cov hlua mus rau ib puag ncig pob zeb ntawm daim ntawv cog lus stresses. Pretensioning tso cai rau tus nqi-zoo thiab cov tswv cuab precast.
Prestress hloov mus ntev yog dab tsi?
Qhov ntev hloov (Lt) ntawm lub zog ua kom muaj zog yog txhais raws li qhov ntev los ntawm qhov kawg ntawm txoj hlua mus rau qhov chaw uas qhov kev ntxhov siab zoo (fse) yog tsim(saib Daim duab 2-2). Tom qab tso tawm lossis txiav cov hlua khi, kev ntxhov siab maj mam hloov mus rau cov pob zeb ib puag ncig los ntawm kev sib cog lus ncaj qha.
Prestress tendon yog dab tsi?
Prestressing tendons (feem ntau ntawm cov high tensile steel cables los yog rods) yog siv los muab cov clamping load, uas ua rau muaj kev ntxhov siab los tawm tsam qhov kev ntxhov siab uas cov tswvcuab compression. yuav txwv tsis pub dhau vim muaj kev khoov load (saib daim duab 2).
kev poob siab yog dab tsi?
Qhov kev poob qis yog txhais raws li qhov poob ntawm tensile kev nyuaj siab nyob rau hauv lub prestress steel uas ua rau lub pob zeb ntawm lub prestressed qhob seemHauv pretensioned qhob, plaub qhov loj ntawm prestress poob yog elastic shortening (ES), creep (CR), shrinkage (SH) thiab so (RE).

Dab tsi yog qhov hloov pauv hloov pauv tau?
Subscripted Variable. Subscripted variables yog siv los khaws cov txiaj ntsig ntawm tib hom hauv ib qho array. Nws kuj tseem pab peb khaws cov txiaj ntsig ntau dua hauv ib lub npe sib txawv. Subscripted variables tau tshaj tawm los ntawm kev muab lub npe sib txawv nrog rau cov ntawv sau npe .
Dab tsi yog qhov hloov pauv hloov pauv hauv siab transmitter?
Kev sib piv - qhov piv ntawm qhov siab tshaj plaws thiab qis tshaj qhov ua tau ncua sij hawm rau lub transmitter. (Piv txwv li, yog 1, 000 psi transmitter muaj qhov sib piv ntawm 5: 1, ces qhov siab tshaj plaws tau ncua yog 0 mus rau 1, 000 psi thiab qhov qis tshaj plaws tau ncua yog 0 txog 200 psi.
Dab tsi yog kev hloov pauv hloov pauv?
Kev hloov pauv hloov pauv yog hom tshwj xeeb ntawm kev sib raug zoo rau kev ua kom muaj kev hloov pauv. Charles Tilly txhais nws tias "kev sib raug zoo txhawb nqa kev sib tw tshwj xeeb rau kev tswj hwm lub xeev, lossis qee ntu ntawm nws.
Dab tsi yog qhov kev hloov pauv hloov pauv?
Nyob rau hauv molecular biology thiab noob caj noob ces, transcriptional regulation yog cov txhais tau tias los ntawm lub cell tswj kev hloov ntawm DNA rau RNA, yog li orchestrating noob kev ua si. Tus tswj hwm kev hloov pauv ua dab tsi?
Qhov txawv ntawm kev hloov pauv thiab hloov pauv yog dab tsi?
Raws li verbs qhov txawv ntawm kev hloov pauv thiab hloov yog tias hloov pauv yog siv rau qhov chaw ntawm lwm yam, nrog tib txoj haujlwm thaum hloov yog rov qab mus rau qhov qub, txoj haujlwm, condition, or the like . Qhov txawv ntawm kev hloov pauv thiab hloov pauv hauv Excel yog dab tsi?
