Diffusion - yog ...

Diffusion - yog (lus), dispersion, kis, kis tau. Lub cev, qhov no lub sij hawm piav lub zog hloov lwm lub tsev los yog teeb meem ntawm siab concentration cheeb tsam mus rau ib tug tsawg concentration. Feem ntau, uas yog kev cob cog rua nrog lub diffusion - qhov no nws roj molecules (e.g., thaum lub naj hoom yog faib nyob rau hauv cov huab cua) los yog kua. Cov tib cov txheej txheem yuav tsum tau cai nyob rau hauv khib nyiab. Piv txwv li, yog hais tias tus kawg ntawm tus pas nrig yog electrically them los yog thaum tshav kub kub, lub tshav kub (los yog them nyiaj) yuav maj mam kis los ntawm cov kub xaus rau tus mob khaub thuas. Nyob rau hauv cov ntaub ntawv no, yog hais tias peb coj lub daim hlau, lub cua sov yuav kis tau sai heev, thiab cov hluav taws xob tam sim no - instantly. Yog hais tias tus pas nrig yog ua los ntawm cov khoom cua khoom, lub thermal faib yuav qeeb thiab lub electric - txawm qeeb qeeb. Diffusion ntawm cov khib nyiab no tshwm sim rau ib tug tseem qis ceev.

Nws yuav tsum tau muab sau tseg hais tias lub sij hawm (zoo li ntau lwm tus neeg) yog siv niaj hnub no, tsis yog nyob rau hauv physics.

Muaj yog, piv txwv li, ib lub tswvyim xws li cov diffusion ntawm innovation. Nws yog ib tug txheej txheem los ntawm cov uas kis tau tus mob yog ua nyob rau hauv lub sij hawm nrhav ua lag ua luam chaw ntawm kev sib txuas lus raws. Nyob rau hauv cov ntaub ntawv no, diffusion - ib lub tsev ntaub ntawv, tshaj tawm thiab kev zoo yog nyob ntawm seb siv kev sib txuas lus raws. Yog tseem ceeb heev thiab tshwj xeeb tshaj yog cov xaav ntawm cov ntaub ntawv chaw ua lag ua luam kev ua ub no raws li tau zoo raws li lawv muaj peev xwm ua daim ntawv thov ntawm cov uas nrhiav. Thaum lub diffusion ntawm innovation, tau ib zaug mastered thiab thov nyob rau hauv lwm qhov chaw, nyob rau hauv qhov chaw tshiab thiab tej yam kev mob ntawm ib tug zuj zus pes tsawg tus neeg thiab producers. Lub laaj ntawm tus txheej txheem ntawm txoj kev ua ib thaj tsam ntawm daim ntawv thiab nthuav tawm ntawm nrhav nyob rau hauv kev ua lag luam khwv nyiaj txiag.

Kws txawj taw tes kom paub tias nyob rau hauv lub chav kawm ntawm lub lag luam muaj ib tug diffusion cim cyclical. Nyob rau tib lub sij hawm qhov kev siv ntawm qhov kev siv cov txheej txheem, cov kis ntawm kev nrhav muab faib ua tej theem: yooj yim thiab thov kev tshawb fawb, kev loj hlob thiab tsim, kev tsim kho, kev loj hlob, thiab manufacturing, muag thiab marketing.

Kev cai diffusion - ib lub tswvyim uas yog siv nyob rau hauv cov kev sib raug kheej. Nws characterizes no txhais txheej txheem ntawm kev sib nrig sib allergic ntawm ib co yam ntxwv ntawm ib tug kev sib raug zoo pab pawg neeg mus rau lwm rau kev sib cuag. Nyob rau hauv cov ntaub ntawv no, diffusion yuav tsis tawm tej yam imprint rau tej yam ntawm interacting haiv neeg. Nws yuav, txawm li cas los, kuj tshwm sim hais tias qhov no allergic yuav ntxias ib tug muaj zog thiab sib npaug zos (los yog unilateral) cawv. Lub raws los ntawm kev uas lub diffusion yuav siv sij hawm qhov chaw - nws yog mas tourism, pejxeem tsiv teb tsaws, kev tsov kev rog, luam, kev sib tham, fairs thiab miv, pauv ntawm cov kws tshwj xeeb thiab cov tub ntxhais kawm.

Tawm ntawm innovation nyob rau hauv cov kev sib raug sector yuav nqa tawm nyob rau hauv ob cov lus qhia: horizontally los mas.

Kab rov tav allergic (diffusion intergroup) cai cov tib neeg, pab pawg muaj sib npaug zos raws li txoj cai.

Vertical loj hlob yuav siv sij hawm qhov chaw ntawm kev kawm muaj tsis zoo tib raws li txoj cai. Qhov no yog hu ua stratification diffusion.

Tsoos haiv neeg yog yus muaj los ntawm ib tug qhia leb polarization ntawm cov pejxeem. Raws li ib tug xov tooj ntawm kev coj noj coj, ib qho piv txwv ntawm txoj kev ua neej thiab style ntawm hnub no (rau ob qho tib si ntau dua thiab txo chav kawm ntawv) yog suav tias yog nruab nrab hauv chav kawm ntawv.

Kev cai diffusion coj mus rau lub neej, ob leeg zoo thiab tsis zoo nta. Yog li, cov kis ntawm siab conception ntawm lub neej nyob rau hauv qhov nruab nrab thiab (tshwj xeeb tshaj yog) lub sab strata ntawm lub ntsiab lus, nyob rau hauv ib tes, lub democratization ntawm kev kawm ntawv thiab cov neeg. Nyob rau lwm cov tes, siab kab lis kev cai nyob rau hauv cov ntaub ntawv no muaj peev xwm yuav ntaus nqi txheej thaum ub thiab ploj mus.
