Khadadka Perfect - dhabanada axial nolosha

Tan iyo wakhtiyadii hore, nin ayaa sameeyay fikrado quruxda. All curiyay quruxda badan ee dabiiciga ah. In ay jidka u gaar ah dadka la jecel yahay, xayawaanka qurxoon iyo dhirta. Joy daawasho isha dhagaxa qaaliga ah ama cusbo crystal ah, waa ay adag tahay in aan u bogi balanbaalis ama snowflake. Laakiin maxay tahay sababta this dhacdo? Waxa ay u muuqataa inoo view sax ah oo dhamaystiran oo alaabta, qeybtii midig iyo bidix oo u muuqdo mid ah sida in image muraayad.

Sida muuqata, ugu horeysay fikirka ah nuxurka quruxda fanaaniinta. sculptors Baydka wax ku bartay qaab-dhismeedka jidhka bini'aadamka, ee BC qarnigii V ee Waxaan bilaabay si aad u dalbato fikirka ah "dhabanada". ereygaas waa ka soo jeedo Greek iyo waxay ka dhigan tahay wada noolaanshaha, saamiga iyo is-shabbaha qaybo ka qayb goobta. Faylasuuf Giriigga ee hore Plato ku dooday in ganaax noqon karaa oo kaliya in symmetrical iyo qalanta.

In xisaabta, joomateri iyo dhabanada loo arkaa saddex nooc: dhabanada axial (qaraabo ilaa laynka toosan), dhexe (qaraabo u barta) iyo muraayadda (qaraabo in diyaarada).

Haddii kasta oo ka mid dhibcood shayga dhexdeeda leeyahay khariidaynta saxda ah ka xarunteedii - heysta dhabanada dhexe. Its tusaale ahaan waa jidhka joomateri sida dhululubo, gudbikaraa, askunmay midig, iwm

dhibcood dhabanada Axial of a xad toosan dhigayaa in line this gudbo dhexe ee qeybta biiray dhibic iyo dadab iyo in ay. Tusaalooyinka ka dhidibka dhabanada, bisector undeployed xagal of labaale Saddexagal, wax kasta oo si toos ah khadka barbaro iyada oo xarun ka mid ah goobada, iwm Haddii tiradaasi joomatari sifo dhabanada axial, go'aan ka soo baxay dhibcood specular la visualized karo si fudud iyadoo biish ay dhidibka iyo ku daray toortaha siman "fool ka fool". dhibcood la doonayo la taabto.

Marka dhabanada muraayad dhibcaha shayga ku yaalaan identically qaraabo in diyaarad in maraa ay xarunta.

Nature waa xigmad leh oo caqligal ah, si ku dhowaad dhammaan of curiyay ay leeyihiin qaab habboonaanta. Tani waxay khusaysaa labada dadkuba ku nool iyo waxyaabaha walax. Waayo, qaab dhismeedka of noocyo badan oo nolosha lagu gartaa mid ka mid ah saddex nooc oo dhabanada: laba dhinac, radial ama spherical.

Inta badan, ka axial dhabanada ee dabiiciga ah oo laga dheehan karo in dhirta in dadab iyo horumarinta si ay dusha sare ee ciidda. Xaaladdan oo kale dhabanada ku keentey ka wareeg ah xubno isku mid ah oo ku saabsan dhidibka caadi ah xarunta. Xaglaha iyo inta jeer ee ay heshiis noqon kartaa kala duwan. Tusaale ahaan waa geedaha: gran, Maple iyo kuwa kale. In xoolaha qaar ka mid ah, dhabanada ka axial sidoo kale waa wax caadi ah, laakiin ay dhacdo dhif ah. Dabcan, dabeecadda waa dhif lagu gartaa sax xisaabeed, laakiin isku mid ah oo ay xubno ka mid ah jirka oo weli duwanyihiin.

Bayoolajiga sii kordheysa arkay ma dhabanada axial, iyo laba dhinac (laba geesood ah). Her tusaale ahaan waa baalasha balanbaalis ama baalkaa-biyood ah, caleemaha dhirta, Tent ubax, iwm Xaalad kasta, qaybaha midig iyo bidix ee wax nool waa u siman yihiin oo waa image muraayad ah oo midba midka kale ah.

dabeecad dhabanada goobaabin midhaha dhirta badan, kalluunka qaar ka mid ah, molluscs iyo fiiruska. A tusaalooyin dhabanada radial waa kalluun, noocyo ka mid ah gooryaan, echinoderms.

In indhaha aadanaha kaqabto waxaa inta badan la xidhiidha aan sax ahayn ama cuuryaanimada. Sidaa darteed, in inta badan shuqullada gacmahaaga aadanaha ogan dhabanada iyo wada noolaanshaha.
