Cov duab khov yog peb-dimensional cov duab uas muaj qhov ntev, dav thiab qhov siab. Saib qee qhov piv txwv ntawm peb-dimensional cov duab hauv qab no. Lub prism yog ib tug polyhedron nrog raws nraim ob lub ntsej muag uas yog congruent thiab parallel. Cov ntsej muag no hu ua lub hauv paus. Lwm lub ntsej muag hu ua lateral faces.
Ib yam li ntawd, cov piv txwv ntawm cov duab zoo li cas?
Qee qhov piv txwv ntawm cov duab zoo : Lub khob hliav qab, Cuboid, Sphere, Lub tog raj kheej, lub voos xwmfab. Lub voos xwmfab muaj 6 lub ntsej muag uas sib npaug squares, 12 cov npoo sib npaug thiab 8 vertices. Cuboid muaj 6 lub ntsej muag lub ntsej muag uas lub ntsej muag sib npaug sib npaug.
Ib tug kuj yuav nug, qhov txawv ntawm lub dav hlau cov duab thiab cov duab khoom yog dab tsi? A dav hlau daim duab yog ob-dimensional, thiab a daim duab yog peb-dimensional. Cov qhov sib txawv ntawm lub dav hlau thiab cov duab khov yog nyob rau hauv lawv qhov ntev. Qhov twg ib square yog a dav hlau daim duab , nws 3D counterpart, lub voos xwmfab, yog a daim duab.
Ib yam li ntawd, muaj pes tsawg hom ntawm cov khoom muaj nqis?
yam chaw uas peb nyob
- Peb Dimensions. Nws yog hu ua peb-dimensional,
- Tej yam yooj yim. Cia peb pib nrog qee cov duab yooj yim tshaj plaws:
- Cov khoom. Cov khoom muaj cov khoom (tshwj xeeb txog lawv), xws li:
- Polyhedra thiab Non-Polyhedra. Muaj ob lub ntsiab ntawm cov khib nyiab, "Polyhedra", thiab "Non-Polyhedra":
Cov khoom yog dab tsi?
A khov kho yog tus yam ntxwv los ntawm cov qauv rigidity thiab tsis kam mus rau lub zog siv rau saum npoo. Tsis zoo li kua, a khoom khoom tsis ntws mus rau hauv cov duab ntawm nws lub thawv, thiab nws tsis nthuav mus sau tag nrho cov ntim muaj xws li roj.

Dab tsi yog cov cim siv hauv daim duab kos duab?
Schematic Symbols Wires (Txuas Txuas) Cov cim no sawv cev rau kev sib koom hluav taws xob sib txuas ntawm ob yam khoom. Hlau (tsis txuas) DC Supply Voltage. Hauv av. Tsis muaj kev sib txuas (nc) Resistor. Capacitor, Polarized (Electrolytic) Lub teeb-Emitting Diode (LED)
Dab tsi yog cov khoom node hauv daim duab kos duab?
Cov khoom node yog ib qho kev ua haujlwm tsis txaus ntseeg uas yog siv los txhais cov khoom ntws hauv ib qho kev ua si. Cov khoom nodes muaj xws li tus pin, central buffer, parameter, expansion nodes. Nws yog qhov txawv me ntsis tias txawm hais tias cov khoom node yog qhov kev ua haujlwm tsis txaus ntseeg, nws tau siv ncaj qha rau hauv cov khoom ntws siv nws tus kheej cov cim (saib hauv qab)
Cov kws kos duab hu li cas cov duab thiab cov duab siv los sawv cev rau cov yam ntxwv ntawm lub ntiaj teb nto?
Ntiaj Teb Kev Tshawb Fawb - Daim Ntawv Qhia Lub Ntiaj Teb Qhov Nto A B GLOBE Ib puag ncig uas sawv cev rau lub ntiaj teb nto. SCALE Siv los sib piv qhov deb ntawm daim ntawv qhia lossis lub ntiaj teb mus deb ntawm lub ntiaj teb nto. SYMBOLS Ntawm daim duab qhia chaw, cov duab siv los ntawm mapmakers sawv ntsug rau cov yam ntxwv ntawm lub ntiaj teb nto. TSEEM CEEB Ib daim ntawv teev cov cim siv rau ntawm daim ntawv qhia
Dab tsi yog qhov txawv ntawm lub xeev daim duab kos duab thiab daim duab ua haujlwm?
Lub xeev daim duab qauv yog siv los qhia qhov sib lawv liag ntawm lub xeev uas ib yam khoom mus dhau, qhov ua rau kev hloov ntawm ib lub xeev mus rau lwm qhov thiab qhov kev txiav txim uas tshwm sim los ntawm lub xeev hloov. Daim duab ua haujlwm yog ntws ntawm kev ua haujlwm yam tsis muaj qhov tshwm sim (kev tshwm sim) mechanism, lub xeev tshuab yog suav nrog lub xeev triggered
Dab tsi yog qhov zoo thiab qhov tsis zoo hauv daim duab?
Cov duab zoo yog cov duab ntawm cov khoom tiag tiag (xws li lub qhov rais ncej). Cov duab tsis zoo yog qhov chaw nyob nruab nrab ntawm cov khoom (xws li qhov chaw nyob hauv lub qhov rais ncej)
