Neeg kho tshuab kev nyuaj siab lub cev - txhais thiab mis khoom ntawm Khoom tawv

Nyob rau hauv cov tshuaj tiv thaiv ntawm cov khib nyiab uas txawv tej yam, kev hloov tej zaum yuav tshwm sim - ob sab hauv thiab sab nraud. Ib tug piv txwv yog lub hom tshwm nyob rau hauv lub cev sab hauv. Nws txiav txim cov neeg kawm ntawv uas tau hloov nyob rau hauv cov ntaub ntawv ntawm kev puas tsuaj.

Basic ntsiab nyob rau hauv physics

Neeg kho tshuab kev nyuaj siab - ib qho kev ntsuas ntawm lub sab hauv lub zog ntawm tus kwv, uas tshwm sim nyob rau hauv tus ntawm ntau yam. Piv txwv li, thaum ib tug deformation thaum lub sij hawm uas tus sab nraud rog yog sim hloov cov txheeb ze txoj hauj lwm ntawm tus hais, thiab nrog - tabkaum txoj kev no, limiting nws mus rau tej qho nqi. Yog li, peb yuav hais tias cov neeg kho tshuab kev nyuaj siab - nws yog ib tug ncaj qhov tsim nyog tau kev nyuaj siab nyob rau hauv lub cev.

Ob hom kev nyuaj siab yuav tsum tau qhia:

1. Qhov - yog thov mus rau lub chav tsev cheeb tsam ntawm tus ntoo khaub lig seem ib txwm mus rau nws.
2. Tangent - yog thov mus rau lub ncoo seem ntawm ib tug tangent rau nws.

Lub totality ntawm cov txhawj xeeb sawv ntawm ib tug taw tes, hu ua txoj kev nyuaj siab lub xeev nyob rau ntawm no point.

Ntsuas nyob rau hauv pascals (Pa) hom: muab xam mis yog sawv cev hauv qab no

Q = F / S,

Qhov twg Q -Mechanical kev nyuaj siab (Pa), F - quab yuam generated los ntawm cov deformation hauv lub cev (H), S - cheeb tsam (hli).

Thaj chaw ntawm Khoom tawv

Khib nyiab, ib yam li tag nrho cov lwm tus neeg, xws li atoms, tab sis lawv muaj ib tug heev muaj zog qauv uas tsis yog undergoes deformation, i.e. ntim thiab zoo nyob twj ywm qhov. Tej khoom muaj ib tug xov tooj ntawm txawv thaj chaw uas muaj peev xwm yuav muab faib ua ob yam loj xws li:

1. Lub cev.
2. Tshuaj.

Rau cov tib neeg muaj xws li cov nram qab no:

1. Neeg kho tshuab - kawm nrog cov coj los rau ntawm lub cev. resilience yuav tsum tau ntaus nqi rau cov zog, lub fragility, lub dag lub zog, piv txwv li, tag nrho cov uas muaj feem xyuam rau cov muaj peev xwm mus tiv thaiv deformation tshwm sim los ntawm lwm yam tseem ceeb.
2. Thaum tshav kub kub - mus kawm tus ntawm txawv kub rau tus kwv. Cov muaj xws li cov expansion rau cua sov, thermal conductivity, Thaum tshav kub kub muaj peev xwm.
3. Hluav taws xob cov - cov khoom no txuam nrog rau electron tsab ntawv tsa suab sab hauv lub cev thiab nws muaj peev xwm mus sib sau ua ke rau hauv ib qho kom kwj thaum raug lwm yam. Piv txwv li - fais conductivity.
4. Kho qhov muag - kawm siv lub teeb fluxes. Cov zog muaj xws li lub teeb rog xav txog, haum ntawm lub teeb diffraction.
5. Sib Nqus - txiav txim los ntawm qhov kuaj ntawm magnetic moments nyob rau hauv ib tug khoom lub cev Cheebtsam. Rau lawv, raws li tau zoo raws li rau hluav taws xob thiab teb cov lus tsis zoo them hais vim nws cov qauv thiab tej taw.

Cov tshuaj zog muaj xws li txhua yam muaj feem xyuam rau cov tshuaj tiv thaiv rau effect tsim nyog tshuaj thiab cov txheej txheem uas tshwm sim thaum lub sij hawm no. Piv txwv li - oxidation degradation. Tus qauv ntawm tus siv lead ua ntxaij ntoo kuj koom rau cov khoom zog.

Nws yog tseem tau mus faib ib tug me me pab pawg neeg ntawm physicochemical zog. Qhov no muaj xws li cov neeg uas raug ua ob nyob rau hauv lub neeg kho tshuab thiab nyob rau hauv lub tshuaj. Piv txwv li - combustion, thaum lub sij hawm uas hloov tshwm sim rau ob tug yam ntxwv saum toj no.
