MAVJI ZARBATI

MAVJI ZARBATI, sohai guzarishi tangbar (hangomi yakbora afzudani fishor, harorat, surat va zichii modda), ki nisbat ba muhit bo surati favqussado pahn meshavad. Mavji zarbati hangomi tarkish (nig. rasm), harakati jismho bo surathoi favqussado, razryadhoi elektrii puriqtidor va g. ba vujud meoyad. Mavji zarbatiro dar laboratoriya dar gulbahoi zarbati, ki az kamerahoi balandfishor (puri gazi kori) va pastfishor (puri gazi tadqiqshavanda)-i az yakdirap bo diaframma judokardashuda iboratand, hosil mekunand. Hangomi pora shudani diaframma gazi kori vase meshavad va dar kamerai shafat Mavji zarbati ba vujud meoyad. Qonuniyathoi paydoish va pahnshavii Mavji zarbatiro gidrodinamika va dinamikai gaz meomuzad.

Mavji zarbatii tarkishi yadroii havoi.

Dar nazariyai tarkishho Mavji zarbati gufta hamai on massai muhit (odatan havo)-ro mefahmand, ki fishurda va ba harakat ovarda shudaast; sathi hududi bayni muhiti fishurda va muhiti noangekhtaro (ki dar harakat ast) boshad, fronti Mavji zarbati menomand. Dar mavridi tarkishhoi yadroi baroi dar muhit (havo, ob, zamin) hosil shudani Mavji zarbati qarib 50% energiyai tarkish sarf meshavad.

Mavji zarbati dar fizika, khimiya, tekhnika baroi omukhtani holatho va tabadduloti modda hangomi fishor va harorathoi baland, ba amal ovardani guzarishhoi fazavii gunogun (mas., az grafit hosil kardani almosi suni), tagyir dodani rafti reaksiyahoi khimiyavi dar muhithoi gunogun va g. istifoda meshavad.
