Lachitsanzo zopezera deta m'malo mwa masanjidwe wosavuta kumva. Pakati pake penipeni, chitsanzo maukonde ndi zofanana kwambiri ndi utsogoleri wolowezana, alinso zigawo, kuti ndi chinthu mizu yomwe awasungira Chofunika kwambiri. Pakati pa mfundo amaphatikizidwa kudzera kulumikizana. Ndi mfundo yomwe ili pa mtunda wofanana ku mfundo muzu kupanga, monga chitsanzo masanjidwe, misinkhu. The peculiarity wa chitsanzo masanjidwe chinali ku mchitidwe wina ndi mzake zitha kukhala njira imodzi, ndipo maukonde si choncho, pali maulendo angapo. Lachitsanzo zopezera deta amapereka mwayi kumanga nyumba zambiri zovuta kwa deta. Izi ndi Chachikulu kusiyana pakati pa zitsanzo ziwirizi.

Kuti akonze chitsanzo deta anazindikira ubale "ambiri ambiri" ndi kukonzedwa munthawi yomweyo zolakwa wogwila mu chitsanzo masanjidwe, omwe kuzindikiridwa pa nthawi. Maukonde deta chitsanzo zachokera ntchito chiphunzitso Zithunzi. Kuyambira mfundo imeneyi, iwo limafanana ndi Zithunzi umasinthasintha. Mu pempheroli, mbadwa akhoza kukhala chiwerengero cha makolo. Network Nawonso achichepere imakhala ya mbiri, nati anapereka mgwilizano omwe alipo pakati pa zolembedwa deta. Awiri mitundu ya mbiri, kuti ndi kholo ndi mbeu, kudziwa mitundu ya kugwirizana. mtundu kulankhulana Mwachitsanzo ambiri akuimira Mwachitsanzo mmodzi wa kholo kujambula ndi kulolerana wa anatilamula ya zinthu za thupi mtundu kulowa mwana. Pansi pa mndandanda wa anthu ambiri amadziwira ngati akonzedwa dzina lake kulembamo komwe mbiri mtundu analengeza mwini akonzedwa, ndi kulembamo ena - imeneyi ya anthu.

Lachitsanzo deta maukonde ali ndi peculiarities. mitundu yonse ya kugwirizana ntchito ayenera kukhala zinchito, kuti ndi "anthu ambiri chimodzi", "limodzi ndi khamu" kapena "munthu mmodzi". Lachitsanzo okha internally anafotokoza mfundo yoti mtundu wa kugwirizana ndi mtundu winawake wa mbiri kholo ndi mbeu ya mtundu wa kujambula zinthu kwenikweni ena anakumana. Pofuna kudziwa ubwenzi "ambiri ambiri" mtundu wapadera kulembamo wakhala anayambitsa, komanso nsapato zinchito ulalo wa mawonekedwe "limodzi ndi kuchuluka" ndi "ambiri ndi munthu." Ngati ndi kotheka, mfundo zina akhoza kuwonjezeredwa ku kujambula, kuchita ntchito ya Mitsemphayi.

Maukonde chitsanzo asapita gulu zambiri kufotokoza mtundu ubale wa "wina ndi akonzedwa", ndiye mwini wake wa mmodzi, koma iye ali zambiri atumiki. Munthu angathe tchulani chitsanzo cha mkhalidwe umenewu monga "ntchito." Apa zikutanthauza kuti pa wantchito ntchito mu dipatimenti iliyonse, koma aliyense dipatimenti mwina ntchito ndi ogwira ntchito ochepa. Maukonde chitsanzo mtundu "umodzi ndi kuchuluka" ubale mabungwe osiyanasiyana akuyendera mwa ubale gulu.

Maukonde chitsanzo Nawonso achichepere zimaphatikizapo kugwiritsa ntchito ntchito zotsatirazi pa deta:

- Kumbukirani, inu ndi kulowa mfundo Nawonso achichepere wathu;

- kuti monga mu mtima gulu, amene anaika pakati pa kulankhulana zimenezi;

- lophimba, ndiko kuti kusintha kwa chimodzi membala kwa mwini ina;

- pomwe, ndiye, kuti kusinthidwa aliyense deta;

- Tingafinye, kutanthauza kuti agwire ntchito pa kuwerenga deta;

- kuchotsa, ndiye kuti nkhani kapena thupi kuchotsa deta;

- akatsimikizire mbiri ubale gulu, ndiye kuchita kuswa kugwirizana pakati deta.

Chonchi chitsanzo deta ndi zinthu zapadera kwa deta mpheto panyanja pakati pawo. The navigation wagawo mu chitsanzo Zithunzi kukhazikitsidwa kwa timva zimene mukufuna kugwiritsa ntchito ina mpheto deta. zochitika zimachititsa panopa. Lachitsanzo maukonde akhoza kupezeka kwa kusintha panopa kwa Mwachitsanzo wotsatira wa mfundo panopa ndi mzake umasinthasintha vertex kugwirizana panopa umene anazindikira ndi ubale gulu. Navigation angayambe ndi kujambula umasinthasintha.
