Dab tsi yog cov ntau hom kev siv hluav taws xob ? Muaj peev xwm (khaws cia) thiab kinetic (hauv kev txav). Nyob rau hauv cov nqe lus ntawm kinetic zog , muaj tiag tiag tsuas yog ob yam: linear thiab rotational. Txhua nrog peb qib ntawm kev ywj pheej sawv cev rau txhua qhov loj ntawm lub cev.
Yog li ntawd, dab tsi yog 3 hom mechanical zog?
Nws tau qhia los ntawm William Rankine, tus kws tshaj lij xyoo 19th, thiab tus kws kho lub cev. Muaj peev xwm zog los nyob rau hauv peb daim ntawv - lub peev xwm gravitational zog , hluav taws xob muaj peev xwm zog , thiab elastic muaj peev xwm zog . Gravitational peev xwm zog hais txog cov zog uas yog khaws cia rau hauv cov khoom vim lawv txoj hauj lwm ntsug.
Ib tug kuj yuav nug, dab tsi yog mechanical zog muab piv txwv? Lub ntsiab txhais ntawm mechanical zog yog lub zog uas ib yam khoom tau txais los ntawm nws txoj haujlwm thiab kev txav mus los. Ib piv txwv ntawm mechanical zog yog lub zog ntawm kev ncaws pob ya saum huab cua. Ib piv txwv ntawm mechanical zog yog ib lub pob tawg uas swung rov qab deb ntawm lub tsev.
Ib tug kuj yuav nug, dab tsi yog qhov txawv ntawm txhua yam zog?
Mechanical zog ** Muaj ob lub ntsiab hom mechanical zog . Lawv yog motion zog thiab khaws cia mechanical zog . Tsab ntawv tsa suab zog : Qhov no yog zog ib yam dab tsi muaj vim nws txav mus (xws li lub pob ci ci nrawm nrawm).
Qhov twg yog qhov piv txwv zoo tshaj ntawm kev siv tshuab hluav taws xob?
Daim ntawv thov ntawm Mechanical Zog Lub tshuab demolition yog qhov zoo heev piv txwv ntawm ob lub peev xwm thiab kinetic mechanical zog . Lub pob wrecking muaj peev xwm mechanical zog thaum nws raug tsa mus rau ib txoj hauj lwm ntsug saum av. Lub pob muaj peev xwm ua haujlwm vim nws txoj haujlwm ntsug.

Dab tsi yog qhov txawv ntawm kev txuag hluav taws xob thiab lub hauv paus ntsiab lus ntawm kev txuag hluav taws xob?
Lub caloric txoj kev xav tau khaws cia tias cov cua sov tsis tuaj yeem tsim los yog rhuav tshem, qhov kev txuag ntawm lub zog ua rau lub hauv paus ntsiab lus tsis sib xws uas cov cua sov thiab cov tshuab ua haujlwm sib hloov tau
Dab tsi yog hom hluav taws xob hluav taws xob sib txawv?
Qhov sib txawv ntawm cov hluav taws xob hluav taws xob muaj nyob hauv cov hluav taws xob hluav taws xob muaj xws li xov tooj cua tsis muaj zog, microwaves, infrared tsis, pom lub teeb, ultraviolet hluav taws xob, X-rays, thiab gamma rays. Ib feem ntawm cov electromagnetic spectrum uas peb tuaj yeem pom yog qhov pom lub teeb spectrum
Dab tsi yog cov yam ntxwv ua siab hloov hluav taws xob hloov hluav taws xob LET muaj thaum piv nrog LET hluav taws xob tsawg?
Dab tsi yog cov yam ntxwv ua kom muaj hluav taws xob hloov hluav taws xob siab (LET) hluav taws xob muaj thaum piv nrog cov hluav taws xob qis-LET? Cov huab hwm coj ntau ntxiv, txo qhov nkag mus. (Vim lawv cov nqi hluav taws xob thiab cov khoom loj heev, lawv ua rau ntau ionizations hauv cov ntaub so ntswg, sai sai poob lub zog
Puas yog hluav taws xob them nqi hluav taws xob tsuas yog hluav taws xob lossis yog tus nqi ntawm tag nrho cov atoms?
Tus nqi zoo attracts tus nqi tsis zoo thiab ua rau lwm tus nqi zoo. Puas yog hluav taws xob them nqi hluav taws xob tsuas yog hluav taws xob lossis yog tus nqi ntawm tag nrho cov atoms? Cov nqi hluav taws xob yog cov cuab yeej ntawm tag nrho cov atoms
Dab tsi yog qhov zoo ntawm kev siv lub tshuab hluav taws xob hloov hluav taws xob hauv atomic absorption?
Qhia qhov zoo thiab qhov tsis zoo ntawm lub cub tawg piv nrog kev siv cov nplaim taws hauv atomic absorption spectroscopy. Cov txiaj ntsig tseem ceeb yog ntau dua rhiab heev (concentration thiab tshwj xeeb tshaj yog loj). Lub ntsiab tsis zoo yog cov cuab yeej cuab tam ntau dua thiab cov nqi ntsuas
