Zizindikiro zomwe zimawonjezera nthawi ya zolemba ndi kupuma

M'magawo oyambilira, tidalemba zolemba zoyambira komanso kutalika kwake. Koma pali mitundu yosiyanasiyana ya rhythms mu nyimbo kotero kuti nthawi zina njira zopatsirana izi sizokwanira. Lero tisanthula njira zingapo zomwe zimathandizira kujambula mawu ndi kupuma kwaukulu wosagwirizana.

Poyamba, tiyeni tibwereze nthawi zonse zazikulu: pali zolemba zonse ndi kupuma, theka, kotala, chisanu ndi chitatu, chakhumi ndi chisanu ndi chimodzi ndi ena, ang'onoang'ono. Chithunzi chili pansipa chikuwonetsa momwe amawonekera.

Komanso, kuti titithandize, tiyeni tigwirizanenso pamisonkhanoyi kwa nthawi yaitali m’masekondi. Mumadziwa kale kuti nthawi yeniyeni ya cholemba kapena kupuma nthawi zonse imakhala yamtengo wapatali, osati nthawi zonse. Zimatengera kuthamanga komwe kugunda kwa nyimbo kumagunda. Koma pazolinga zamaphunziro, tikukulimbikitsani kuti muvomereze kuti cholemba cha kotala ndi 1 sekondi, theka lachidziwitso ndi masekondi 2, cholemba chonse ndi masekondi 4, ndipo zomwe zili zosakwana kotala - zisanu ndi zitatu ndi khumi ndi zisanu ndi chimodzi zidzatero, motsatana. zoperekedwa kwa ife ngati theka (0,5 .1) ndi 4/0,25 ya sekondi (XNUMX).

Kodi madontho angawonjezere bwanji nthawi ya cholemba?

MFUNDO - kadontho kamene kaima pafupi ndi cholembacho, kumanja kumawonjezera nthawi ndi theka ndendende, ndiko kuti, nthawi imodzi ndi theka.

Tiyeni titembenuzire ku zitsanzo. Cholemba cha kotala chokhala ndi kadontho ndi chiŵerengero cha nthawi ya kotala yeniyeniyo ndi cholemba china chomwe chiri chachifupi kuwirikiza kawiri kuposa kotala, ndiko kuti, chachisanu ndi chitatu. Ndipo chimachitika ndi chiyani? Ngati tili ndi kotala, monga momwe tinavomerezera, kumatenga mphindi imodzi, ndipo yachisanu ndi chitatu imakhala theka lachiwiri, ndiye kotala ndi dontho: 1 s + 1 s = 0,5 s - masekondi ndi theka. Ndizosavuta kuwerengera kuti theka lomwe lili ndi dontho ndi theka lokha kuphatikiza kotala la nthawi ("theka la theka"): 1,5 s + 2 s = 1 s. Khalani omasuka kuyesa ndi utali wonsewo.

Monga mukuonera, kuwonjezeka kwa nthawi ndi kwenikweni pano, choncho dontho ndilothandiza kwambiri komanso lofunika kwambiri ndi chizindikiro.

MFUNDO ZIWIRI - ngati sitiwona chimodzi, koma mfundo ziwiri zonse pafupi ndi cholembacho, ndiye kuti zochita zawo zidzakhala zotsatirazi. Mfundo imodzi imatalika ndi theka, ndipo mfundo yachiwiri - ndi gawo lina ("theka theka"). Zonse: cholemba chokhala ndi madontho awiri chimawonjezeka nthawi ndi 75% nthawi imodzi, ndiko kuti, ndi magawo atatu.

Chitsanzo. Cholemba chonse chokhala ndi timadontho tiwiri: chilemba chonsecho (4 s), kadontho kamodzi kamene kamaimira kuwonjezera theka (2 s) ndipo kadontho kachiwiri kamasonyeza kuwonjezeredwa kwa nthawi ya kotala (sek 1). Ponseponse, zidamveka masekondi 7, ndiye kuti, mpaka makota 7 munthawi imeneyi. Kapena chitsanzo china: theka, nalonso, lili ndi madontho awiri: theka lokha kuphatikiza kotala, kuphatikiza lachisanu ndi chitatu (2 + 1 + 0,5) palimodzi masekondi 3,5 omaliza, ndiye kuti, pafupifupi ngati cholemba chonse.

Inde, n’zomveka kuganiza kuti mfundo zitatu ndi zinayi zingagwiritsidwe ntchito mofanana mu nyimbo. Izi ndizowona, kuchuluka kwa gawo lililonse latsopanoli kudzasungidwa mumayendedwe a geometric (theka la gawo lapitalo). Koma muzochita, madontho atatu ndizosatheka kukumana, kotero ngati mukufuna, mutha kuchita nawo masamu, koma simuyenera kudandaula nawo.

Fermata ndi chiyani?

FERMATA - ichi ndi chizindikiro chapadera chomwe chimayikidwa pamwamba kapena pansi pa cholembera (mungathenso pa kupuma). Ndi arc yopindika mu semicircle (mapeto amawoneka pansi ngati nsapato ya akavalo), mkati mwa semicircle iyi muli mfundo yolimba mtima.

Tanthauzo la fermata likhoza kusiyana. Pali njira ziwiri:

1. Mu nyimbo zachikale, fermata imachulukitsa nthawi ya cholemba kapena kupuma ndi theka ndendende, ndiko kuti, zochita zake zidzakhala zofanana ndi zomwe mfundo.
2. Mu nyimbo zachikondi ndi zamakono, fermata amatanthauza kuchedwa kwaulere, kosawerengeka kwa nthawi. Wosewera aliyense, atakumana ndi fermata, ayenera kusankha yekha kutalika kwa cholembacho kapena kuyimitsa, komanso kuti asunge nthawi yayitali bwanji. Inde, zambiri pankhaniyi zimadalira mtundu wa nyimbo ndi mmene woimbayo akumvera.

Mwinamwake, mutatha kuwerenga, mukuzunzidwa ndi funso: chifukwa chiyani timafunikira fermata, ngati pali mfundo ndipo pali kusiyana kotani pakati pawo? Mfundo ndi yakuti nthawi zonse madontho amathera nthawi yaikulu muyeso (ndiko kuti, amatenga nthawi yomwe timawerengera pa CHIMODZI-NDI, CHIWIRI-NDI, ndi zina zotero), koma fermats satero. Fermatas nthawi zonse amakhala okalamba ndi zowonjezera, "nthawi ya bonasi". Choncho, mwachitsanzo, mu miyeso inayi (kuwerengera ma pulses mpaka anayi), fermata pa noti yonse idzawerengedwa mpaka sikisi: 1i, 2i, 3i, 4i, 5i, 6i.

Plus League

LIGI - mu nyimbo, iyi ndi zolemba zolumikizira arc. Ndipo ngati zolemba ziwiri za msinkhu womwewo zimagwirizanitsidwa ndi mgwirizano, womwe, kuwonjezera apo, umayima motsatira mzere, ndiye kuti apa cholemba chachiwiri sichikugwedezekanso, koma chimangogwirizanitsa choyamba "chopanda phokoso" . Mwanjira ina, ligi, titero, ilowa m'malo mwa chizindikiro chowonjezera, amangophatikizira ndipo ndi momwemo.

Ndikuwoneratu mafunso anu amtunduwu: chifukwa chiyani osewera amafunikira ngati mutha kungolemba nthawi yayitali nthawi imodzi? Mwachitsanzo, magawo awiri amalumikizana ndi ligi, bwanji osalemba hafu imodzi m'malo mwake?

Ndikuyankha. Mgwirizanowu umagwiritsidwa ntchito nthawi zomwe sizingatheke kulemba "zambiri" zolemba. Zimachitika liti? Tinene kuti cholemba chachitali chikuwoneka pamalire a miyeso iwiri, ndipo sichikukwanira muyeso woyamba. Zoyenera kuchita? Zikatero, cholembacho chimangogawanika (kugawidwa m'zigawo ziwiri): gawo limodzi limakhalabe muyeso umodzi, ndipo gawo lachiwiri, kupitiriza kwa zolembazo, zimayikidwa kumayambiriro kwa muyeso wotsatira. Ndiyeno zomwe zidagawanika zimasokedwa pamodzi ndi chithandizo cha mgwirizano, ndiyeno ndondomeko ya rhythmic sichisokonezedwa. Chifukwa chake nthawi zina simungathe kuchita popanda ligi.

Liga ndiye chomaliza mwa zida zotalikitsa zomwe timafuna kukuuzani lero. Mwa njira, ngati madontho ndi fermatas amagwiritsidwa ntchito ndi zolemba zonse ndi kupumandiye nthawi zolembera zokha ndizolumikizidwa ndi ligi. Kuyimitsa sikulumikizidwa ndi osewera, koma mophweka, ngati kuli kofunikira, kumatsatana motsatizana kapena kumakulitsidwa nthawi yomweyo ndikupuma kwinanso "kwamafuta".

Tiyeni tifotokoze mwachidule. Choncho, tinayang'ana zizindikiro zinayi zomwe zimawonjezera nthawi ya zolemba. Awa ndi madontho, madontho awiri, minda ndi ligi. Tiyeni tifotokoze mwachidule za zomwe achita mu tebulo wamba:

M'nkhani zam'tsogolo tidzapitiriza kulankhula za nyimbo za nyimbo, kuphunzira za katatu, quartoles ndi nthawi zina zachilendo, komanso kusanthula bwino mfundo za bar, mita ndi siginecha ya nthawi. Tiwonana posachedwa!

Okondedwa, mukhoza kusiya mafunso anu mu ndemanga za nkhaniyi. Ngati mumakonda zomwe zaperekedwa, nenani za izi pamasamba ochezera, mabatani apadera omwe muwona pansipa adzakuthandizani pa izi. Zikomo chifukwa chakumvetsera!
