A yadawa coefficient - inda kuma nawa

Summer! Sun, zafi, iska, wari da freshly yanke ciyawa. Grass yadda nisa, da kuma wari ne ji. Wannan ne kimiyyar lissafi, wannan sabon abu ne ake kira yadawa. Kuma shi ne m da shigar azzakari cikin farji na barbashi abubuwa a lamba tare da juna. Alal misali, kamar yadda na yanzu, da ciyawa zo a cikin lamba tare da iska, da kuma wari na yanke ciyawa shimfidawa ta hanyar iska da nisa daga mowing. A irin wannan tsari ne yawanci halin da irin wannan girma da yadawa coefficient.

Za mu iya cewa duk abin da ya faru a kusa da mu ne sun fi mayar saboda da matakai na interpenetration. Saboda wannan sabon abu, mun ko da rayuwa. Menene haka mamaki game da wannan? shigar azzakari cikin farji na oxygen ko gina jiki a cikin jini - wannan shi ne hakikanin yadawa na daya abu da ke shiga more. Tartsatsi yadawa a cikin yanayi ne da yawa mafi fadi fiye da mu zaton. Irin wannan sabon abu ne ba da wani abu m, amma a maimakon haka, aka yadu wakilci a duniya. Ko da cewa da iska exhaled da mutum ba ya tara a kusa da kuma tarwatsa a sarari, kuma saboda yadawa.

Interpenetration iya faruwa a wani iri-iri jikin - ruwa, gaseous kuma m. Its dalili ne m motsi na abu kwayoyin. Af, sabon abu na yadawa aka dauke a cikin kwayoyin-sanadin motsi ka'idar daya daga cikin goyon bayan dalilai na shi. Yanzu, ya dawo zuwa jiki na tari: da permeation kudi na wani abu dogara a kan ta Jihar tari da kuma irin wannan girma a matsayin yadawa coefficient.

Menene wannan m ra'ayi? Don haka ya kira gwada yawa halayyar da canja wurin kudi na kwayoyin abubuwa a wani. A yadawa coefficient, wanda shi ne quite musamman dabara, damar kima daga cikin adadin abu ratsa naúrar yankin (murabba'in mita) da naúrar lokaci (na biyu).

A yi, shi ya gano cewa, a cikin gas interpenetration auku mafi hanzari, da kuma kudi na shigar azzakari cikin farji ne kadan a cikin daskararru. A cikin yadawa coefficient na da tasiri na jiki zafin jiki da kuma natsuwa daga abubuwa juna kusa. Tare da kara yawan zafin jiki interpenetration kudi ƙaruwa tare da kara maida hankali ga abu - ma.

Kamar wancan interpenetration sabon abu ne saboda abin da ake kira taro dan tudu ko zazzabi dan tudu. By irin yadawa ne zuwa kashi free kuma tilasta. Tilasta taso a ƙarƙashin rinjayar waje tsaro. Dangane da irin tilasta yadawa aka bayyana a matsayin wani thermal, lantarki, da kuma Baro zuwa gaba.

Yadawa ne yadu amfani a cikin art. Daya daga cikin mafi hankula misalai - yadawa waldi. Jigon wannan fasaha ne sauki: a haɗa biyu daban-daban jikuna (bari kawai biyu ƙarfe), sa'an nan azabtar da su da matsa lamba da kuma yawan zafin jiki. Karshe a girma kasa da narkewa zafin jiki na abu.

A sakamakon haka ne da shiga na biyu jũna kayan. Irin wannan fasahar da aka yi amfani da ko'ina a cikin wutar lantarki da kuma lantarki masana'antu, a yi da manyan aka gyara na hadaddun siffar, da kuma a cikin gwaji kananan-sikelin samar. Irin wannan waldi iya za'ayi a karkashin yadu sãɓãwar launukansa yanayi, har zuwa injin yanayi, duk ƙaddara da takamaiman bukatun ga ƙãre samfurin.

Wani daidai da na kowa, yin amfani da sabon abu na yadawa ne ta yin amfani da samar da semiconductor Tsarin. Daya daga cikin fasahar domin samar da p-n mararraba dogara ne a kan sabon abu na interpenetration. Lokacin da fallasa su high yanayin zafi, gabatowa da narkewa zafin jiki, da wani crystal tsarin da aka samu tare da so yanki taro na impurities.

Da la'akari da manufar "yadawa coefficient" yarda tabbatar musamman tartsatsi interpenetration abubuwa a yanayi, kazalika da a daban-daban embodiments na ta yin amfani a cikin art.
