Ebholeni, usayizi webhola unomthelela omkhulu ngomthelela omuhle womdlalo kanye nokuba khona komdlali. Phakathi kokucaciswa okuningi kwebhola, inombolo yebhola le-5 yibhola le-quasi-match, futhi ubukhulu bayo, isisindo kanye ne-circumference kulawulwa ngokuqinile. I-quasi-circumference yebhola lebhola lezinyawo le-No. 5 kanye nohlu lwayo olujwayelekile luzochazwa ngokuningiliziwe ukukusiza uqonde kangcono le ndawo.

, Ukucaciswa kwebhola kanye nezinhlobo zebhola

ubukhulu obuhlukahlukene nemizila, zingahlukaniswa zibe yizinhlobonhlobo zokucaciswa okuhlukile. Phakathi kwabo, ibhola le-No. 5 liyibhola le-quasi-match, okufanele lisetshenziswe kabanzi emincintiswaneni ehlukahlukene esemthethweni kanye nezikhathi zokuqeqesha. Ngaphezu kwalokho, kukhona namabhola ebhola lezinyawo osayizi abahlukene njengeNombolo 1, No. 2 noNombolo 3, asetshenziswa kakhulu yintsha nezingane zeminyaka ehlukene namazinga okuqeqesha.

2. I-quasi-circumference

yomncintiswano webhola lezinyawo wamazwe omhlaba we-No. 5 ibeka ukuthi i-quasi-circumference yebhola le-No. 5 kufanele ibe phakathi kuka-68 cm no-70 cm. Guqula kumamilimitha, okungukuthi i-680 mm kuya ku-700 mm. Le parameter iqinisekisa ukuzinza okufanele nokusebenza kwezemidlalo kwebhola uma lisemoyeni.

3. Indlela yokulinganisa

i-Perimeter Ukulinganisa ukuzungeza kwebhola akuyona inkimbinkimbi, futhi kungaba yithuluzi lokulinganisa lochwepheshe noma isilinganiso esilula se-tape. Lapho ulinganisa, isilinganiso se-tape kufanele senziwe ngokuzungeza i-equator yebhola (okungukuthi, phakathi kwebhola) ukuqinisekisa ukuthi isikhundla sokulinganisa sinembile futhi ukugwema ukusonteka kwebhola okubangelwa amandla angaphandle ngesikhathi senqubo yokulinganisa. Izithelo ezilinganisiwe kufanele zihlangabezane nobubanzi obujwayelekile ukuze kubhekwe njengokujwayelekile.

Okwesine, umngcele webhola

uthinteka yizinto ezihlukahlukene ezifana nezinto, izinqubo zokukhiqiza kanye nomfutho womoya. Phakathi kwabo, ukukhethwa kwezinto ezibonakalayo kuthinta ngqo isisindo nokuqina kwebhola; Inqubo yokukhiqiza ithinta ukuma nokunemba kwebhola; Umfutho womoya ushintsha ubulukhuni nokusebenza kwendiza yebhola ngokulungisa ivolumu yomoya webhola. Ngakho-ke, lezi zinto zidinga ukulawulwa ngokuqinile ngesikhathi senqubo yokukhiqiza ukuqinisekisa ukuthi ukuzungeza kwebhola kungaphakathi kwebanga elijwayelekile.

5. Umthelela ongajwayelekile womngcele webhola

wukuthi ukuzungeza kwebhola kuphambuka kakhulu ebangeni elijwayelekile, okuzothinta ukukhiqizwa komdlalo. , ukuzungeza ngokweqile kungabangela ukuthi ibhola linciphise lapho lindiza emoyeni, lithinta ukubukeka komdlali; Uma i-circumference incane kakhulu, ibhola lingase libe nzima kakhulu ukugxuma futhi kunzima ukulawula. Ngaphezu kwalokho, ubukhulu obuhlukahlukene bamabhola ebhola emdlalweni ofanayo nakho kungaholela ekudwebeni. Ngakho-ke, ukuqinisekisa ukunemba kwe-circumference yebhola kubaluleke kakhulu kokubili okuhle nabasubathi.

I-quasi-perimeter yebhola le-No. 5 kanye nobubanzi bayo benani elijwayelekile, kanye nendlela yokulinganisa, izici ezithinta kanye nemiphumela engavamile yethulwa ngokuningiliziwe. Ukuze kuqinisekiswe ubuqotho bomdlalo kanye nokuba khona kwabasubathi, kunconywa ukuthi lapho ukhetha futhi udlala ibhola, imithetho eqinile nemigomo kufanele isetshenziselwe ukukhetha nokufaneleka kwebhola. Ngaphezu kwalokho, kufanele kuqashelwe ukuvikela ibhola ngesikhathi senqubo ukugwema ukugqoka ngokweqile nokulimala okungaholela ekushintsheni komngcele. Ekugcineni, kufanelekile ukuhlola njalo nokulinganisa ukuzungeza kanye neminye imingcele yebhola ukuqinisekisa ukuthi bahlangabezana nobubanzi obujwayelekile.

Ngokuqaliswa, nginokuqonda okujulile kwe-quasi-perimeter yebhola le-No. 5. Emincintiswaneni yesikhathi esizayo nokuqeqeshwa, sicela uqiniseke ukuthi unake ukucaciswa kanye nekhwalithi yebhola ukuqinisekisa ukuncintisana okuhle nokuphepha kwabadlali. Uma unemibuzo mayelana nosizo, sicela ukhululeke ukubonisana nolwazi noma uthintane nochwepheshe.
