Motlakase tšimo mela. selelekela

Khetholla scalar le tšimo vector (tabeng ena e tla ba ea motlakase tšimo vector). Ka lebaka leo, ba ile ba ba bopile mesebetsi scalar kapa vector ea okamelang le nako.

tšimo Scalar hlalosa mosebetsi oa mofuta o φ. masimo a joalo ka pono di behilwe sebelisa boemo tšoanang tsa bokaholimo: φ (: x, featswan, med) = mdlody, ka c = const.

Re ka hlalosa ho vector, eo e lebisitsoe ikutloeleng lebetsoeng le kgolo ya mosebetsi φ.

Boleng feletseng vector ena rerang tekanyo ea phetoho ea mosebetsi φ.

Ho hlakile hore, ea tšimo scalar chelete tšimo vector.

tšimo ena ea motlakase o bitsoa 'nang,' me mosebetsi φ o bitsoa hlahelang. boemo o tšoanang oa ho holim'a metsi bitsoa bokaholimo equipotential. Ka mohlala, nahana e ea tšimo motlakase.

Masimo a ditshwantsho tse bontshiweng haha thoeng motlakase tšimo mela. Leha ho le joalo ba ba bitsoa mela vector. Sena tangent mocheng oa ho ntlha eona e bontšang tataiso ea tšimo motlakase. palo ea mela e fete sebakeng se unit trust e tekanyo e lekanang ya ho boleng feletseng vector ho.

Re hlahisang kgopolo ya ho vector differential hammoho mola k. vector ena e lebisitsoe hammoho le tangent ho mola k le boleng ho feletseng e lekanang le differential legal dl.

Ha re re mohlomong fuoa itseng tšimo ea motlakase, e leng se ke ke ho hlokahala ho nahana kamoo mela ea tšimo. Ka mantsoe a mang, re fumana hore na coefficient la boela la atolosoa (khutsufatso) K vector ho tsamaisane le differential ena. Go lekantsha le differential dikarolo le vector, re fumana mokhoa oa ditekanyo. Mora nyalano e, o ka bopa e abel tsa mela e matla.

The and analysis vector tshebetsong tse fanang ka boitsebiso bo mabapi le eo mela la lebotho la tšimo ea motlakase etsahala taba e itseng. Re hlahisang kgopolo ya "ts'ebetsong vector" holim'a S. The tlhaloso ka molao phallo ea F e tjena: boleng e nkoa e le sehlahisoa sa ka tloaelehileng bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb differential ho unit trust e tloaelehileng vector ho holim 's. Orth e khethileng e le hore e hlalosang mantsoe e hlalosa ho bokantle holim'a ntho e tloaelehileng.

Papiso pakeng tsa khopolo phallo ea tšimo 'me phallo ea taba: ntho ka yuniti ya nako e ntse e feta ka holim'a metsi e le eena perpendicular ho ea tšimong ho phalla. Haeba mela la lebotho la tšimo electrostatic leng teng ntle ho tloha holim 'S, joale e ntan'o ba phallo e ntle,' me haeba ua hlokomoloha - mpe. Ka kakaretso, kemisong ka hakanya palo ea mela tšimo eo hlaha ho tswa ho holim'a metsi. Ka lehlakoreng le leng, ho ts'ebetsong ke tekanyo e lekanang ka palo ea mela ea matla a phunyeletse ka elements holim'a.

The fapoha tsa mosebetsi vector e balwa ka ntlha eo e e bofilwe bophahamo ba modumo ΔV. S - holim koahela bophahamo ba modumo ΔV. Sebelisa ho fapoha ntlha ka sebaka lumella ho khetholla ho ba teng ha ka ho eona ea mehloli ea tšimo. Nakong compression holim S ka nako P ea motlakase tšimo mela phunyeletsang holim, ba lule ka tsela e lekanang. Haeba sebaka ha se ntlha mohloding tsa naha (dutla kapa a tsoelang), joale e ntan'o ba holim compressive ka nako ena tekanyo ea mela matla, ho qala ka motsotso itseng lekanang lefela (palo ea mela ka hare ho holim S o lekana le palo ea mela tsoang holim'a ena).

The bohlokoa koetsoeng sekgoqetsane L ka beha tšebetso ea male rotor e bitsoa ajoa ya motlakase hammoho le ea moeli ea male rotor L. Sebelisa ho tsejoa ka tšimo ntlha ka sebaka. Tataiso ea male rotor ea etsang qeto ea boholo ba phallo ea tšimo koetsoeng pota ntlha e itseng (male rotor tšimo e tšoaeang vortex) le tataiso ea oona. E Thehiloe ho boikemisetso ba male rotor, ka lengths e bonolo ka balwa motlakase boqapi vector ka Cartesian hokahanya tsamaiso, le motlakase mela tšimo.
