Tib neeg tsis tau xav txog lub neej yam tsis muaj watches rau ntau pua xyoo thiab tab tom txhim kho cov txheej txheem no tas li. Nws muaj peev xwm ua tiav qhov tseeb tsis txaus ntseeg ntawm chav kawm - +/- 5 vib nas this ib hnub. Xws li cov khoom siv nyuaj yog kim heev, tab sis nyob rau hauv lub neej niaj hnub qhov tseeb muab los ntawm quartz watches txaus txaus, tshwj xeeb tshaj yog vim lawv muaj rau txhua tus neeg.

Hnub no, feem ntau ntawm cov kev txav saib ua hauv ntiaj teb yog quartz. Qee lub sij hawm, saib ntawm tes los yog vib nas this flashing ntawm cov qhab nia, koj ntes koj tus kheej xav: "Kuv xav tias lawv ua haujlwm li cas?" Thiab yog tias tsab xov xwm no ntes tau koj lub qhov muag, cia peb nres ib pliag thiab thaum kawg nrhiav seb lub moos quartz yog dab tsi.

Qhia txog yam tseem ceeb

Lub ntsiab tseem ceeb hauv kev saib xyuas yog lub cev muaj zog thiab lub tshuab hluav taws xob. Ib zaug ib ob, lub thaiv xa hluav taws xob teeb liab rau lub cev muaj zog, thiab nws tig cov xub. Lub cav thiab thaiv yog siv los ntawm microbattery, uas yog tsim rau ntau xyoo. Wind up quartz watch Notsim nyog.

Lub tshuab hluav taws xob muaj lub tshuab hluav taws xob ntawm hluav taws xob oscillations thiab ib qho kev faib uas hloov lawv. Lub tshuab hluav taws xob muaj cov quartz siv lead ua, uas yog lub hauv paus ntawm cov pulses periodic. Lawv kis tau zoo heev vim yog cov nyhuv piezoelectric ntawm crystal.

Qhov peculiarity ntawm quartz oscillator yog tias cov pulses generated los ntawm nws muaj ntau zaus - 32768 oscillations ib ob. Yog li ntawd, lub divider hloov lawv mus rau hauv oscillations nrog ib tug zaus ntawm 1 hertz thiab hloov lawv mus rau lub winding ntawm lub stepper lub cev muaj zog. Thaum dhau los ntawm lub kauj, ib qho hluav taws xob impulse excites ib magnetic teb nyob rau hauv nws, uas ua rau lub rotor txav ib nrab tig. Uas, nyob rau hauv lem, rotates tus xub. Qhov no yog li cas lub moos quartz ua haujlwm.

Lawv cov txheej txheem tuaj yeem suav tias yog lub khoos phis tawj me me, vim tias lub khoos phis tawj microcircuit tuaj yeem hloov lawv mus rau hauv cov khoom siv ntau yam, suav nrog lub sijhawm nres, chronograph, lub tswb moos, lub ntsuas phoo, thiab lwm yam. Qee zaum lawv siv cov duab digital es tsis txhob siv lub xov tooj.. Nyob rau hauv cov ntaub ntawv no, lub sij hawm cov ntaub ntawv yog tso tawm nyob rau hauv daim ntawv ntawm cov zauv, tab sis lawv tseem yog raws li ib tug crystal oscillator.

Kev tsim ntawm lub zog ntawm cov muaju yog qhov yooj yim heev. Nws yog ib qho tseem ceeb uas quartz watches tsis muaj cov khoom ua haujlwm nyob rau hauv lub xeev ntawm nro. Yog vim li ntawd lawv thiaj li ruaj khov. Lawv mechanism yog tas li raug txhim kho. Tsis xav tias quartz watches tau dhau los ua neeg nyiam.

Peb tsis txawm xav txog qhov tseeb tias cov txheej txheemRaws li cov khoom siv hluav taws xob quartz thaiv, lawv kuj ua haujlwm hauv txhua yam khoom siv hluav taws xob paub uas muaj lub sijhawm kho: khoos phis tawj, xov tooj ntawm tes, navigation systems, ntsuas lub plawv dhia, thiab lwm yam.

Peb tuaj yeem hais tias los ntawm kev xaiv quartz watches, peb them se rau tam sim no, vim lawv tau tsim dhau 40 xyoo dhau los. Cov neeg txhawb nqa ntawm cov tshuab saib xyuas tam sim no tsis muaj tsawg dua li cov neeg kho tshuab. Lub moos peb hnav ntawm peb lub dab teg ua rau peb zoo ib yam li peb cov ntawv nyiam, tsheb lossis khaub ncaws.

Nws ntseeg tau tias cov qauv quartz raug xaiv los ntawm cov neeg muaj zog uas muaj nuj nqis rau lawv qhov tseeb thiab tsis muaj kev cia siab hauv cov watches. Ntxiv nrog rau lub dab teg saib, quartz phab ntsa, rooj, thiab qhov cub saib yog tsim. Yuav luag txhua lub tsev thiab chaw ua haujlwm muaj cov neeg saib xyuas uas tsis nkees ntawm peb lub sijhawm. Ntau haiv neeg hauv kev tsim thiab kev ua haujlwm, thawj thiab yooj yim, lawv ib txwm nrog peb. Lawv xav tau thiab hloov tsis tau.
