Khoom siv rau Basic Physics Laboratory Instruments

Hauv kev xaiv cov khoom siv rau kev sim physics yooj yim, cov tuam txhab lag luam feem ntau muab qhov tseem ceeb ntawm qhov sib npaug ntawm kev ruaj ntseg, ruaj khov, thiab ntsuas qhov tseeb. Cov khoom sib xyaw ua ke feem ntau yog tsim los ntawm cov khoom siv hlau-xws li aluminium alloys lossis stainless hlau- uas muaj lub zog tensile siab thiab zoo heev corrosion kuj. Cov khoom no ua kom ntseeg tau tias cov khoom siv tswj hwm lawv cov qauv kev ncaj ncees thiab tiv thaiv deformation, txawm tias tom qab siv ntev. Tsis tas li ntawd, cov khoom siv hlau muaj qhov cuam tshuam rau kev cuam tshuam sab nraud, yog li pab txo qis qhov cuam tshuam ntawm ib puag ncig ntawm cov txiaj ntsig kev sim.

Rau cov khoom uas xav tau kev rwb thaiv tsev zoo tshaj plaws los yog lub teeb yuag, engineering plastics lossis cov ntaub ntawv sib xyaw feem ntau yog ua haujlwm. Cov ntaub ntawv no yog lub teeb yuag, yooj yim rau kev tsim, thiab muaj peev xwm ua kom muaj hluav taws xob zoo heev, ua rau lawv zoo tagnrho rau kev sim hluav taws xob lossis kev siv uas tiv thaiv luv luv Circuit Court yog qhov tseem ceeb. Hauv cov cuab yeej nrog cov kev ua haujlwm nruj dua, cov khoom siv tshwj xeeb kuj tau siv. Piv txwv li, tooj liab-nrov npe rau nws qhov tshwj xeeb conductivity- yog siv rau kev sib txuas hluav taws xob hauv hluav taws xob, thaum cov ceramics - tau sau tseg rau lawv cov thermal stability zoo tshaj - yog ua haujlwm nyob rau hauv cov khoom raug kub los yog xav tau siab - ntsuas qhov tseeb. Los ntawm kev txiav txim siab ua ke ntawm cov khoom sib txawv no, cov cuab yeej sim tau tsim los tsis tsuas yog ua kom tiav cov kev xav tau ntawm kev ua haujlwm, tab sis kuj tseem tswj tau qhov kev ua tau zoo thoob plaws ntau yam kev sim.
