The dielectric kuramba dzedenga somunhu wenyama uwandu

Sezvo chikazozikamwa, mhepo yakatipota kunosanganisira magasi akawanda, saka ndiko insulator akanaka. Zvikurukuru, nekuti izvi, kakawanda kacho zvinoita kudzivisa kudiwa mamwe insulating akaturikidzana chero zvinhu akapoteredza kondakita. Nhasi tichataura pamusoro chii dielectric permeability mhepo. Asi kutanga, zvichida, kutanga tsanangudzo chii chinorehwa nemashoko okuti "dielectric".

zvinhu zvose zvichienderana kukwanisa kuitisa Magetsi conditionally mapoka mapoka matatu guru: conductors, semiconductors uye insulators. Kutanga risingamboshandisi kurwisa kuti kumhanya nenzira mhosva nezvimedu pamusoro pavo. The zvikuru boka - resimbi (aruminiyamu, mhangura, simbi). Chechipiri conductive pasi zvimwe zvinhu (nesilicon negermanium). Zvakanaka, zvemagetsi kurwisa kuti wechitatu saka guru kuti magetsi asingadi kupfuura navo. A muenzaniso unoshamisa - mhepo.

Chii chinoitika kana fuma opinda Zvakaitwa yemagetsi munda mapazi? Nokuti conductors kupindura chinhu pachena - magetsi (Chokwadi, kana pane namahwindo loop iyo inopa "nzira" kuti inoramba). Izvi zvinoitika nokuti nzira dzakasiyana-siyana mutariri kudyidzana. Zvakakwana pezvakaitwa siyana anowanikwa pamusoro pakunzwisisa munda pamusoro dielectric zvinhu. Ndichiverenga nesungano pakati nezvimedu pamwe yemagetsi nokuchengeta, zvakaonekwa kuti simba nekuita hakubvi chete pamusoro kusanganiswa tsika mhosva, asi nokubva kwezvakatipoteredza dzakaparadzana navo. Ichi chinhu chinokosha anonzi "dielectric kuramba mashoko." Kutaura zvazviri, ndiye munhu kururamiswa chinhu, sezvo risina divi. Inonzi nhamba simba nekuita mu vacuüm it kuti ukoshi chero zvakatipoteredza. Zvinoreva shoko rokuti panyama "dielectric dzose" zvinotevera: ukoshi Izvi zvinoratidza ukuru attenuation electric munda dielectric zvinhu sezvo zvichienzaniswa Vacuum. Chinokonzera Fani iyi iri ndechokuti mamorekuru kwemashoko haana kushandisa simba yeminda conductivity iri inoramba, uye polarization.

Zvinozivikanwa kuti ari dielectric kuramba kuti mhepo iri kubatana. A mugove kana zvishoma? Ngatimbotaurei zvazviri. Zvino hapana chikonzero kuvimba kwavo kusanganiswa kukosha pachedu permeability nokuda rakajairika zvinhu sezvo mashoko aya kupiwa nhengo pamatafura. Zviya, chaiyo nokuda tafura akadaro anotorwa kunze kukosha chete. The dielectric kuramba mhepo iri kusvika 8 nguva kuvatumwa, somuenzaniso, Micarta. Kuziva nhamba iyi, uye kukosha kupomerwa uye daro pakati pavo inogona vakaverenga pamusaka nekuita kwavo proviso mhepo kuparadzana svikiro kana aiise Micarta.

The yemaitiro simba:

F = (Q1 * Q2) / (4 * 3,1416 * E0 * Es * (R * R)),

apo Q1 uye Q2 - nokuchengeta mutengo; E0 - permittivity mu Vacuum (a chenguva akaenzana 8,86 muna -12 dhigirii); Es - permittivity mhepo ( "1" kana kukosha mimwe zvokunyama, Table); R - kure pakati kupomerwa. miganhu All vanobviswa sezvakatenderanwa SI maitiro.

Regai kunyonganisa mbiri pfungwa dzakasiyana - "permeability mhepo" uye dielectric chenguva. Magnetic ndechimwe hunhu chero fuma, uyewo rinomiririra coefficient, asi ayo dzimwe pfungwa - ukama dzesango zvakanyanya uye kukosha rinobva induction mune imwe fuma. Munguva Masvomhu vaishandisa chiero - rinobva permeability kuti vacuum. rokutanga uye rechipiri mashoko Vose anoshandiswa kuita Masvomhu-siyana magetsi mano.
