Physics hauv tshuaj thiab nws cov luag hauj lwm

Physics nyob rau hauv cov tshuaj, raws li nyob rau hauv lwm yam science, yog ib qho tseem ceeb. Nyob rau hauv no tsab xov xwm peb yuav saib ntau cov piv txwv ntawm yuav ua li cas qhov kev kawm muaj feem xyuam rau cov kev kho mob thiab lub neej ntawm cov neeg. Tam sim ntawd peb pom zoo tias mus rau hauv lub complex scientific thiab kev txhawb yuav tsis, thiaj li tsis txhob nkag leej twg yuam kev lawm. Peb npaj mus yuav tau xav txog cov piv txwv.

Yuav ua li cas yog koj kub, mem tes thiab ntshav siab

Tshuaj yuav tsis ua li cas tsis peb tseem ceeb tsis, uas yog lub hauv paus rau kev ntsuag rau cov tib neeg noj qab haus huv: kub, siab, thiab tej zaum kuj txawm mem tes.

Raws li yog lub npe hu, qhov kub thiab txias ntsuas nrog ib tug pas ntsuas kub (nyob rau hauv ntau yog hu ua "tus pas ntsuas kub"). Yuav ua li cas hom ntawm indicators yuav tsum? Cai rau cov tib neeg yog T = 36.6 ⁰ C. Muaj tsis muaj tsis ntseeg, nws yog permissible, piv txwv li, 36.3 ⁰ C thiab 36.8 ⁰ C. Tab sis yog hais tias tus lub cev kub yog siab tshaj 36.9 ⁰ C, peb yuav xyuam xim hais tias ib tug neeg yog unwell.

Yuav ua li cas yog lub luag hauj lwm ntawm physics nyob rau hauv cov tshuaj? Leej twg tau mus kawm lub 7 th rau 11 th (los yog tsawg kawg nyob rau hauv lub 9) qib, lawv paub zoo kawg nkaus zoo hais tias cov kub - nws yog ib lub cev muaj nuj nqis. Ntsuas nyob rau hauv ob peb chav nyob. Tab sis nyob rau hauv Russia yog feem ntau ntsuas nyob rau hauv Celsius. Tus ntsuas kev kub yog mercury, hluav taws xob (nrog ib tug tshwj xeeb sensor).

Siab tseem yog ib qho tseem ceeb heev parameter, tab sis muaj nuances. Tsis yog txhua txhua lub siab ntawm 120 dua 80 yog pab tau. Ib tug neeg ua hauj lwm siab ntawm 110 rau 70, uas yog tseem cai. Ntsuas siv ib tug tonometer (cuff, ib tug huab cua twj tso kua mis pear, gauge). Tseem muaj hluav taws xob, computer sphygmomanometers. Raws li ib tug txoj cai, niaj hnub siv tshuab ib txhij ntsuas siab thiab mem tes. Raws li rau cov chav nyob ntawm kev ntsuas ntawm siab, cov physics uas muaj ntau ntau. Nyob rau hauv cov tshuaj, lub siab yog ntsuas nyob rau hauv millimeters mercury (mm Hg). Mem tes yog yooj yim los mus ntsuas koj tus kheej thiab ntau txhim khu kev qha, vim nws yog tsim nyog los suav yuav ua li cas muaj ntau yam yeej ib feeb tiav.

diagnostic khoom

Kev siv cov physics nyob rau hauv cov tshuaj - nws yog ib tug yuav tsum nyob rau hauv lub ntiaj teb no. Tsis muaj, txawm lub poorest lub chaw tu neeg tsis ua yam uas tsis muaj diagnostic khoom. Txhua qhov txhia chaw yog cov feem ntau nrov ntawm lawv yog:

• X-ray;
• electrocardiographs.

Tsis muaj tsawg thov rau ultrasound pab kiag li lawm, gastroscopy, ophthalmic khoom.

Ntawm cov hoob kawm, los mus tsim cov no los yog lwm yam pab kiag li lawm, koj yuav tau pab nrog ntau zaum. Ntau tshaj ib xyoo yog siv rau nws los tsim txoj cai khoom. Khoom vaj khoom tsev yuav tsum tau nrog ib tug sia tsis tas yuav ua tej kev tsim txom. Tu siab, tsis yog txhua tus ntaus ntawv muaj peev xwm ntawm nws, li ntawd, cov kws kho mob pom zoo kom mus nruj me ntsis soj ntsuam cov koob tshuaj thiab lub sij hawm ntawm qhov kev xeem los yog kev kho mob.

Miracle kawm ntawv: ultrasound

Cov ntaub ntawv kawm muaj xws li physics "oscillations thiab tsis" seem - lub ntsiab ntawm "Suab." Muaj nws peb hom: infrasound (16 mus rau 20 Hz) suab (21 19999 Hertz), ultrasound (los ntawm 20,000 Hertz thiab saum toj no). Yuav ua li cas yog lub "Hertz"? Qhov no oscillation zaus tshwm sim nyob rau hauv cia li ib ob. Peb yuav tau tham txog lub suab yoj, uas nkag mus rau los ntawm ib tug nruab nrab mus rau lwm lub nrog ib tug tej zaus. Lub luag hauj lwm ntawm physics nyob rau hauv txoj kev loj hlob ntawm cov tshuaj nyob rau hauv cov ntaub ntawv no yog raws li nram no: Biophysics zaum, designers invented thiab tseem mus txua ib lub cuab tam haib rau kev kawm cov hauv nruab nrog cev.

Rau hnub tim, ultrasound diagnostics yog ib tug ntawm cov ceev tshaj plaws, tsis mob thiab kev nyab xeeb kev ntawm kev tshawb fawb. Tab sis muaj ib tug drawback: koj tsuas xyuas cov hauv nruab nrog cev ntawm lub plab mog, plab mog, lub raum, cov thyroid. Yog xav paub seb ib tug pob txha lov yog los yog ua li cas rau phem qhov muag los yog hniav, yuav tsis ua hauj lwm.

Sib Nqus resonance imaging thiab computer tomography

Lwm txuj ci tseem ceeb ntawm kev kho mob niaj hnub khoom - ib tug sib nqus resonance imaging (MRI). Qhov no daim ntawv ntsuam xyuas muab ib tug dlaim phaj daim duab ntawm dab tsi tshwm sim nyob rau hauv ib qho kev hloov khoom nruab nrog. Koj yuav qhia tau tam sim ntawd uas MRI ntawm nws hom yog ib tug hloov rau ib tug ultrasound. Yog vim li cas? Raws li peb hais saum toj no, cov ultrasound yuav muaj tseeb tsuas yog tus mob plab nruab nrog cev, lub plab mog thiab thyroid. Pob Txha noj qab haus huv, cov hlab ntsha tsis mus soj ntsuam. Qhov no yuav ua rau cov MRI. Ib tug lwm txoj rau cov ob hom kev kawm (ultrasound thiab MRI) tej zaum yuav ib tug xoo tomography (i).

Nco ntsoov hais tias ultrasound thiab CT soj yuav tsum tau siv ntxiv cov tshuaj los muab ib tug zoo daim ntawv ntsuam xyuas.

physiotherapy

Physiotherapy plays ib qho tseem ceeb luag hauj lwm nyob rau hauv tib neeg lub noj qab haus huv: sov, ultraviolet hluav taws xob, electrophoresis, thiab hais txog.

Yuav ua li cas ntxiv pab ua physics? Nyob rau hauv cov tshuaj, muaj yog ib tug loj tus naj npawb ntawm cov hom ntawm cov khoom, pab kiag li lawm tsis tau tsuas yog rau cov chaw kho mob thiab tsev kho mob. Tam sim no, cov nroj tsuag ua ib co pab kiag li lawm rau lub tsev siv. Piv txwv li, ntau hom tshuaj txau rau ua pa txoj kev kho. Qhov no tej zaum kuj muaj xws li, ultrasound, infrared, electromagnetic pab kiag li lawm.

txuag lub neej

Thaum muaj xwm ceev kho mob loj tej yam kev mob nws yuav ua rau kev txiav txim zoo qhov twg muaj kev cov khoom rov qab. Yog hais tias ib tug neeg mam li nco dheev nres ua tsis taus pa, lub plawv dhia lawm, ces, raws li ib tug txoj cai, nws los mus rov qab mus rau lub neej. Nqa tawm nias lub hauv siab yog tsis ib txwm yooj yim, tab sis kuj txaus ntshai.

Nws yuav pab cov kws kho mob xws li ib tug ntaus ntawv, uas muaj lub npe "defibrillator". Ntawm no yog lwm cov ntaub ntawv ntawm physics nyob rau hauv cov tshuaj. Lub creators ntawm lub ntaus ntawv yog xam, uas tam sim no yuav tsum kis tau los ntawm tib neeg lub siab, khiav nws. Ib qho tseem ceeb yog cov khoom, zoo siv ntawm cov kev cai. Devices ntawm cov khoom cua cua ntawm lub ntsws (ALV) - kuj yog tus nqis nyob rau ntawm physics.

Cov ceg ntawm physics: "Optics thiab teeb"

Txhua tus neeg thib ob nyob rau hauv lub niaj hnub ntiaj teb no ris tsom iav los yog iav. Yuav kom nrhiav tau qhov tseeb yam diopter, koj yuav tsum siv ib tug ntau lub sij hawm. Optics siv nyob rau hauv rub kom pom loj.

Tus nqi ntawm physics nyob rau hauv cov tshuaj yog heev loj, txawm seemingly me me. Optics pib yuav tsum tau siv ib tug ob peb centuries dhau los. Qhov no yog ib tug heev science. Raws li koj paub, muaj sau thiab dispersing lo ntsiab muag. Thiab lawv chaw yuav pom rau ib ntev lub sij hawm. lub nruab nrab tus neeg yuav tsum tau paub qhov txawv ntawm "-1,0" diopter los ntawm, piv txwv li, "1.5"? Rau tus neeg mob myopia nws yog ib qho tseem ceeb heev los xaiv tus txoj cai tsom iav.

Laser pom kev kho, thiab nyob rau hauv Feem ntau laser phais yog heev thiab hauj lwm yooj yim. Zaum no yuam ua hauj lwm nqa tawm cov feem ntau muaj tseeb suav nyob rau hauv thiaj li yuav tau ib tug zoo tshwm sim, thiab tsis yog tus tragic sij hawm.

Kws khomob thiab radiotherapy

Nws yog ib qho tseem ceeb rau cov neeg mob cancer xaiv qhov yog kev kho mob. Nws tsis txaj muag deb ntawm yuav luag txhua tus neeg mob cov kws khomob. Muaj tsis muaj tsis ntseeg tias muaj ntau tshaj xav tau Science News for KIDS paub. Cuaj kaum, tus kws kho mob yuav tsum tau paub yog hais tias ib tug neeg mob yuav tsum tau irradiated.

Nuclear thiab moj physics nyob rau hauv cov tshuaj rau cov neeg mob nrog rau mob cancer yuav ua tau ib txoj kev los cawm lub neej, tsis yog hais tias kom thov nyob rau hauv kev xyaum, tab sis kuj yuav tsim ib tug heev leej cov khoom thiab pab kiag li lawm.

rau cov neeg

Muaj coob tus neeg muaj kev txhawj xeeb txog koj tus kheej noj qab haus huv thiab cov kev kho mob uas peb hlub. Cov niaj hnub ntiaj teb no yog tej uas muaj ib tug ntau yam uas pab tau cov hom kev kawm. Nws yog muag nyob, piv txwv li, nitrates meters nyob rau hauv txiv hmab txiv ntoo thiab zaub, tawg saib, hluav taws xob ntshav qab zib meters (apparatus ntsuas ntshav qab zib ntau ntau), hluav taws xob ntshav siab saib, tsev huab cua noj, thiab li ntawm. Ntawm cov hoob kawm, ib co ntawm cov pab kiag li lawm tsis yog ib tug kev kho mob, tab sis lawv pab tau cov neeg muaj kev noj qab nyob.

Pab ib tug neeg to taub qhov sib txawv readings ntawm lub twj paj nruag yuav tsis tau tsuas yog kev qhia, tab sis kuj lub tsev kawm ntawv physics. Nyob rau hauv cov tshuaj, nws muaj tib txoj cai, units ntawm kev ntsuas, raws li nyob rau hauv lwm yam spheres ntawm lub neej.

Yuav ua li cas npaj koj sau ntawv

Yog hais tias koj lub tsev kawm ntawv, kawm ntawv qib siab los yog lub tsev kawm ntawv yuav tau sau rau ntawm lub npe "Tus luag hauj lwm ntawm Physics hauv tshuaj" sau ntawv (qhia), uas yog, nyob rau hauv no hwm yog ib tug ob peb lub tswv yim:

• sau ib luv luv taw qhia nyob rau hauv cov kev kawm;
• tsim ib lub hom phiaj rau kev sau ntawv hauv cov ntawv nyeem (nws yog ib qho tseem ceeb mus ua txhaum tag nrho cov zajlus kom lo lus no, paragraphs);
• Cia cov ntaub ntawv qhov chaw yuav tsum tau raws li ntau li ntau tau.

Nws yog qhov zoo tshaj plaws tsuas yog sau txog dab tsi koj paub. Nws yog undesirable embed nyob rau hauv kev sau ntawv / daim ntawv qhia tias koj tsis to taub, piv txwv li, ib tug heev scientific piav qhia ntawm yuav ua li cas lub ultrasound los yog apparatus ECG.

Yog hais tias kev sau ntawv / daim ntawv qhia nug nyob rau hauv physics, ces noj xwb lub npe uas koj tau kawm thiab paub zoo. Piv txwv li, lub optics. Yog hais tias koj tseem tsis tau paub nyob rau hauv xov tooj cua physics, nws yog zoo dua tsis mus sau txog tus seev rau cov kev kho mob ntawm cov neeg mob cancer.

Cia lub ntsiab yuav nthuav feem rau koj tus kheej, raws li zoo raws li qhov tseeb. Tom qab tag nrho cov lus nug ntxiv tau qhia kom meej tsis tau tsuas yog cov xib fwb qhia ntawv, tab sis kuj kawm ntawv ua ke / lwm tus menyuam kawm.
