A fiber ntau optic cable yog a network kab uas muaj cov iav iav fibers nyob rau hauv ib tug insulated casing. Lawv tau tsim los rau kev deb, cov ntaub ntawv ua tau zoo kev sib tham , thiab kev sib txuas lus. Fiber optic cables nqa cov teeb liab kev sib txuas lus siv pulses ntawm lub teeb tsim los ntawm me me lasers los yog lub teeb-emitting diodes.
Tom qab ntawd, Dab tsi yog Fiber optic cable siv rau?
Optical fibers yog siv feem ntau yog txhais tau tias xa lub teeb nruab nrab ntawm ob qho kawg ntawm lub fiber ntau thiab nrhiav dav kev siv nyob rau hauv fiber ntau - qhov muag kev sib txuas lus, qhov uas lawv tso cai xa mus ntev dua thiab nyob ntawm qhov bandwidths siab dua (cov ntaub ntawv tus nqi) tshaj li hluav taws xob kab.
Kuj Paub, dab tsi yog kho qhov muag Fiber thiab nws hom? Cov core tuaj yeem yog Yas (siv rau qhov deb heev) tab sis feem ntau yog ua los ntawm iav. Muaj peb leeg hom ntawm fiber ntau optic cable feem ntau siv: ib hom, multimode thiab yas optical fiber ntau (POB). Pob tshab iav los yog yas fibers uas tso cai rau lub teeb coj los ntawm ib kawg mus rau cov lwm yam nrog tsawg tsawg.
Tom qab ntawd, ib tus kuj tseem tuaj yeem nug, qhov Fiber Optic yog dab tsi thiab nws ua haujlwm li cas?
Fiber optics ( optical fibers ) yog ntev, nyias strands ntawm cov iav ntshiab heev txog txoj kab uas hla ntawm tib neeg cov plaub hau. Lawv tau teem rau hauv pob khoom hu ua kho qhov muag cables thiab siv los xa cov teeb pom kev zoo nyob deb deb. Pua pua lossis txhiab tus ntawm cov no optical fibers yog teem nyob rau hauv bundles nyob rau hauv kho qhov muag cov kab.
Dab tsi yog fiber cable ua los ntawm?
A fiber ntau optic cable yog ua los ntawm iav lossis yas tub ntxhais uas nqa lub teeb nyob ib puag ncig los ntawm iav cladding uas (vim nws qhov qis dua qhov ntsuas qhov ntsuas) qhia "khiav tawm" lub teeb rov qab mus rau hauv cov tub ntxhais, ua rau lub teeb raug coj ua raws cov fiber.

Yuav ua li cas cov leeg sib zog tshwm sim ntawm ib leeg cov qib fiber ntau?
Kev Sib Cais ntawm Cov Nqaij Nqaij. Tus ntoo khaub lig sib txuas ntawm cov actin thiab lub taub hau myosin ua rau muaj kev sib zog. Tsuav ntev li Ca ++ ions nyob hauv sarcoplasm los khi rau troponin, thiab tsuav yog ATP muaj, cov leeg nqaij yuav txuas ntxiv kom luv
Ntev npaum li cas yuav tsum muaj daim ntawv pov thawj kev nyab xeeb rau cov khoom phom sij raug khaws cia tom qab cov ntaub ntawv siv tsis siv lawm?
Thaum tsis siv tshuaj lossis khoom siv lawm, SDS raug tshem tawm los ntawm phau ntawv tuav pov tseg thiab pov tseg. Koj qhia nrog Human Resources Manager tias SDS rau tshuaj tsis siv lawm koj tseem yuav tsum khaws cov ntaub ntawv pov thawj kev nyab xeeb thiab lawv yuav tsum khaws cia tsawg kawg 30 xyoo
Kuv yuav ua li cas thiaj paub tias yuav noj cov tshuaj insulin ntau npaum li cas?
Basal / Background thiab Bolus Insulin Doses Basal / keeb kwm yav dhau Insulin Dose. = 40-50% ntawm tag nrho cov tshuaj insulin txhua hnub. 500 ÷ Tag Nrho Cov Tshuaj Txhua Hnub Insulin. = 1 units insulin npog ntau grams carbohydrate. Kev kho qhov tseem ceeb = 1800 ÷ Tag Nrho Cov Tshuaj Insulin Txhua Hnub = 1 units ntawm insulin yuav txo cov ntshav qab zib kom ntau mg / dl
Yuav ua li cas ntau npaum li cas yog umbilical hernias nyob rau hauv cov me nyuam?
Qhov quav no tshwm sim thaum ib feem ntawm lub plab hauv plab, ib feem ntawm txoj hnyuv, thiab / lossis kua los ntawm lub plab, los ntawm cov leeg nqaij ntawm phab ntsa plab. Kev phais mob hauv plab feem ntau tshwm sim hauv 10 feem pua txog 20 feem pua ntawm txhua tus menyuam
Lub hauv paus ntsiab lus ntawm fiber ntau optic cable poob li cas OTDR siv rau kev ntsuas?
Hauv fiber ntau, lub teeb tau tawg mus rau txhua qhov chaw, suav nrog qee qhov tawg rov qab mus rau qhov chaw raws li qhia ntawm no. OTDR siv qhov no 'lub teeb nraub qaum rov qab' los ntsuas nrog rau lub teeb pom kev los ntawm cov khoom sib txuas lossis cov fiber ntau kaw
