Nafwaayay Kinematic. Farsamoyaqaan dheecaan

nafwaayay Kinematic waa dabeecadda aasaasiga ah jirka ah ee gaaska oo dhan iyo warbaahinta dareeraha ah. tiradaasi Tani waa muhiim in la go'aaminayo jiita oo ka mid ah cunnooyinka adkaha dhaqaaqin iyo load, iyagoo ku kulmaan. Sida aad ogtahay, in dunida uu jiro dhaqdhaqaaq kasta oo hawada ama bay'adda biyaha. Sayidka on jidhka ka dhaqaaqin mar walba saamayn dulinka ciidan taas oo ka soo horjeeda in ay jihada ee dhaqdhaqaaqa isu alaabta. Iyadoo la raacayo, sare ku nafwaayay ku kinematic ee dhexdhexaad ah, ayaa in ka badan load ku soo maray by adag ka. Waa maxay nooca ka mid ah guryaha oo cabitaanno ah iyo gaasaska?

nafwaayay Kinematic, qeexaa khilaaf gudaha waxaa sabab u taagoo wakiilka kala iibsiga dardar dadab iyo in ay jihada ee mooshinka of layers ay isagoo xawaare kala duwan. Tusaale ahaan, in cabitaanno kasta oo ka mid ah unugyada dhismaha (Britain) waxa ku wareegsan on dhinacyada oo dhan by dariska dhow ku yaalaan qiyaastii meel fog ka siman yahay si ay dhexroor. Britain kasta oo u dhaxeysa agagaarka booska hoganaya ee loo yaqaan, laakiin garaaca wadnaha ka dariska, waxa ay taasi boodi af xagga xarunta cusub ee oscillation. A unit labaad dhismaha, walax kasta oo sida uu leeyahay waqti in la beddelo meesha isaga joogitaanka qiyaastii boqol milyan oo jeer, samaynta dhexeeya bootin ka mid boqolaal kun oo kala duwan. Dabcan, ka weyn yahay xidhiidhka ka kelli, yar socodka ah ee unug kasta iyo dhisme, sidaas awgeed, walax dheeraad ah ku nafwaayay kinematic.

Haddii mid ka mid ah awoodo dibadda joogta Britain u dhaqmaan on qayb ka mid ah layers xiga, markaas jihada of walxaha Oo Qaliin barakac weyn cutubkan la siiyo waqti badan dhinaca ka soo horjeeda. Sidaa darteed, waxaa lagu beddelay dhaqdhaqaaq qasan gafkii habsami leh xawaare gaar ah, taas oo ku xidhan ciidamada simaha it on. nafwaayay jireenka noocan oo kale ah, tus, saliidaha motor. Waxa kale oo jira oo muhiim ah xaqiiqada ah in ku lifaaqan walxaha hoostiisa tixgelin ciidamada dibadda shaqada on hanti gooni ah layers iyada oo loo marayo taas oo deysa Britain fulinaya. gaadhista noocan oo kale ah ugu dambeyntii waxay kordhisaa heerka of mooshin kaamerada random ah qayb, kaas oo aan isbeddelin waqti. In si kale loo dhigo, marinka biyaha lagu gartaa uniform inkastoo gaadhista joogto ah awoodo dibadda ah in jiho oo kala duwan sababtoo ah waxaa lagu dheelitiri by gudaha caabiga wax layers in si hufan qeexayaa nafwaayay ku kinematic.

Sida heerkulka kordhiyaa dhaqdhaqaaqa ee u taagoo bilaabaa in uu kordhiyo, taas oo horseedaysa hoos u dhac qaar ka mid ah caabiga wax layers, sida walax kasta preheated xaaladaha wanaagsan dheeraad ah dhaqdhaqaaqa xorta ah ee qayb ka ah jihada ciidamada la dabaqay. Tani waxay la barbar dhigi karaa sida uu qofku u fududdahay in ay tuujin iyada oo dadkii badnaa aan kala sooc lahayn u dhaqaaqin badan go'an yahay. tilmaan A weyn oo ku nafwaayay ku kinematic, qiyaasay in Pascals ama Stokes-ilbiriqsi leeyihiin xal polymer. Tan waxa u sabab ay joogaan in ay qaab-dhismeedka ka mid ah silsilado kelli dheer waxaa dhab ah ku xiran. Laakiin la sii kordhaya heerka kulka ah ee ay ku nafwaayay si degdeg ah hoos. Marka adiga oo riixaya ee filamentary caag iyada u taagoo markiiba rigoore isku maran si qasab ah qaado meel cusub.

nafwaayay ee gaaska at heerkul ah 20 ° C iyo cadaadiska Hawada ee 101,3 Pa waa amarka of 10 ^-5 Pa * s. Tusaale ahaan, ku nafwaayay ku kinematic hawada, helium, ogsijiin iyo hydrogen xaaladaha sida uu noqon doonaa siman siday u kala horreeyaan in 1.82 * 10 ^-5; 1,96 * 10 ^-5; 2,02 * 10 ^-5; 0.88 * 10 ^-5 Pa s. A helium dareere ah guud ahaan leeyahay guryaha superfluid la yaab leh. Tani waxay ifafaale, helay by Academician PL Kapitsa been in xaqiiqda ah in biraha firfircoon ee sida gobolka wadar ahaan labada lug ku leeyahay ku dhowaad ma ku nafwaayay. Waayo, isaga, tiradaasi shiidaa eber yahay.
