Izibonelo Jet Propulsion: isithombe

Reactivity kanye nokunyakaza nale - ngempela into okwandile ngokwemvelo. Nokho, izazi zesayensi kanye abaqambi "ababebuthene" futhi alisebenzisela ekuthuthukisweni kwabo lobuchwepheshe. Izibonelo le Jet Propulsion kungabonwa yonke indawo. Ngokuvamile singazi banake yokuthi lokhu noma lokhuya into - isidalwa esiphilayo, indlela lobuchwepheshe - ihamba ngosizo lesi simanga.

Uyini ngamandla jet?

Ngo izilwane zasendle reactivity - inkolo kungenzeka kwenzeka sokuhlukaniswa umzimba ke yimuphi izinhlayiya ngesivinini ethile. Ngo ubunjiniyela jet injini isebenzisa isimiso esifanayo - umthetho ukulondolozwa umfutho. Izibonelo jet ngamandla imishini e rocket, ehlanganisa igobolondo (okuyinto sihlanganisa injini, amadivaysi control, endaweni Ayisebenziswa ezihambayo wezimpahla) nophethiloli nge oxidant, uphethiloli usha, kuphenduke igesi, okuyinto jet ezinamandla wadonsa nibonakala ngokusebenzisa umlomo wombhobho, banikele ngayo yonke isakhiwo isivinini reverse.

Izibonelo ukunyakaza esisheshayo ngokwemvelo

Shiya izidalwa ambalwa zisebenzisa isimiso ukunyakaza ngokukhululekile. Kuyinto sici izibungu Ezinye izinhlobo ojekamanzi, jellyfish, izimbaza - scallop, cuttlefish, ingwane, squid. Futhi emhlabeni isitshalo - flora Zomhlaba - futhi kukhona izinhlobo zisebenzisa lesi simanga ngoba insemination.

"Ikhukhamba Crazy"

Izibonelo jet ngamandla usinikeza flora. Kuphela ukubukeka isitshalo nge isidlaliso ongaziwa iyafana ukhukhamba evamile. Futhi lo epithet "zasendle" usezuze ngenxa hhayi ngempela ngendlela evamile ukuze kusakazeka imbewu. Yokuvuthwa izitshalo nezithelo bounce off the umoba. Imiphumela iba yinhlanganisela yokukhandleka imbobo okuyothi ngalo ikhukhamba Kuphendula uketshezi olune imbewu efanelekayo zokugaya, usebenzisa reactance. Kepha isithelo kanjalo ngimuke kuya ibanga 12 metres esesayidini ingacaci.

Njengoba uhamba cuttlefish?

Izibonelo jet ngamandla is kabanzi amelwe nezilwane. Cuttlefish - cephalopod kokuba uphondo ekhethekile okuyinto ibekwe phambi esifubeni. Therethrough (futhi ngokusebenzisa ezengeziwe umqhewu lateral), amanzi agelezela umzimba isilwane ingaphakathi gill. Lolu ketshezi bese zenyuka ngokushesha kukhishelwa ngokusebenzisa uphondo, futhi cuttlefish tube angaqondisa ecaleni noma emuva. I retroactive okuholela inikeza ukunyakaza bacondze etindzaweni letehlukene.

salpa

Lezi zilwane bavela ozala tunicates - izibonelo ezicacile motion esisheshayo ngokwemvelo. Banezinhliziyo isilinda usayizi encane ayevumela lomzimba bahlala amanzi ebusweni olwandle. Lapho esilwaneni esihambayo adonsa amanzi ngokusebenzisa imbobo elise phambi esifubeni. Lolu ketshezi ibekwa umgodi obanzi zomzimba wayo, okuyinto ahlelwe ngokuphambeneyo zokuphefumula. Salpa kuthatha phuza amanzi, futhi ngesikhathi esifanayo, kuvulwa ivaliwe uvalwe, kanti nemisipha yomzimba - the transverse kanye longitudinal - ukusika. Kuzo zonke umzimba salpa onomfutho, futhi amanzi bephushelwa ngokucijile kude ukuvulwa labaqaphi elingemuva. Ngakho salpa ukusebenzisa isimiso reactivity e ukuhamba kwayo ku-elementi amanzi.

Jellyfish, izimbaza, plankton

Ngo kolwandle kukhona neziboshwa ukuhamba ngale ndlela. Zonke okungenani kanye ngokuqinisekile, uhlezi ogwini, emanzini wahlangana tinhlobo letehlukene jellyfish. Kodwa futhi siqhubekele besebenzisa reactivity. plankton Marine, noma kunalokho, ukuthi eminye imibono yakhe, clams kanye scallop - Basebegcwaliswa bonke ngakho wathutha.

Izibonelo jet ngamandla emizimbeni. squid

Isakhiwo eziyingqayizivele umzimba has a squid. Eqinisweni ngokwesimo oyiyo iqukethe jet injini enamandla, elithatha kahle kakhulu. Lokhu nezilwane omele wezilwandle nasolwandle, ngezinye izikhathi uhlala ekujuleni okukhulu futhi ifinyelela ngezabelo ezinkulu. Ngisho komzimba wesilwane sifana rocket abobunjwa yayo. Okuningi ngokunembile, ke yasungulwa ososayensi yesimanje rocket kulingisa ifomu squid, wadala ngokwemvelo. Futhi a ukunyakaza okuphumuzayo ku zasemanzini imvelo fin isetshenziswa, kodwa uma udinga intuthuko, isimiso reactivity!

Uma ucelwa ukuba: ukunikeza izibonelo jet ngamandla ngokwemvelo, into yokuqala ungasho mayelana lesi silwanyana. isiphuku sakhe kwemisipha ozungezayo umgodi elise emzimbeni. Amanzi ukusivumela ukuba ngaphandle, bese uphonswa ngaphandle kunalokho ngokucijile ngokusebenzisa umlomo wombhobho ewumngcingo (sifana rocket). Umphumela: uhamba squid e jerks kolunye uhlangothi. Lesi sici sivumela isilwane ukuhambisa nge speed kahle eliphezulu, kuyomfica inyamazane yalo, noma ingahlanganyeli nokubajaha. Angaba ukuthuthukisa isivinini ukufanisa kahle umkhumbi yesimanje: kufika amakhilomitha 70 ngehora. Futhi abanye ososayensi liphenya lomkhuba ngokuningiliziwe, ukhuluma ngani isivinini esiphindwe izikhathi ezingu-150 km / h! Ngaphandle kwalokho, ummeleli ocean inekhono ezinhle ngenxa tentacles ugongolo eligoqiwe uzimisele lapho ezihambayo endaweni efanele.
