Indlela ulinganise kwabantu ezibonakalayo? I kwabantu of izinto ezahlukene

Ezindaweni eziningi ukukhiqizwa yezimboni, kanye nokwakhiwa kanye nezolimo isebenzisa umcabango "kwabantu impahla." Lokhu value ngekhompyutha, okuyinto isilinganiso nenqwaba yezinto ezibonakalayo yenqwaba elalihlala kuzo. Ukwazi lokhu ipharamitha, isibonelo, ukhonkolo, abakhi ziyadingeka ukubala inani ke ngokuthulula ezakhiwe ahlukahlukene ukhonkolo: amabhlogo wokwakha, slabs, izindonga eziqinile, amakholomu, sarcophagus zokuzivikela, amachibi, kuphuma, nezinye izinto.

Indlela ukucacisa ukuminyana

Kubalulekile ukuqaphela ukuthi, nangokunquma ukuminyana zokwakha, kungenzeka ukusebenzisa ekhethekile inkomba amatafula, lapho lezi zimiso yanikezwa izinto ezahlukene. izindlela kubala algorithm Kuye asethuthukile, okukuvumela ukuthola ukwaziswa okunjengalokhu kunoma iyiphi umkhuba, uma kungekho ukufinyelela izinto eziyisethenjwa.

I kwabantu kunqunywa kusuka:

• emizimbeni ketshezi kudivayisi hydrometer (isib zonke ezaziwayo inqubo ukulinganiswa kwemigomo a electrolyte imoto ibhetri);
• izinto okuqinile kanye nama-liquid ngosizo ifomula nge kokuqala isisindo futhi ivolumu idatha aziwayo.

Zonke ukubala ezimele, yebo, uyoba efanele, ngoba kunzima thembeke anqume inani, uma umzimba ine ijamo okungajwayelekile.

Amaphutha nesilinganiso ukuminyana

Ukuze abale ngokunembile kwabantu impahla, kufanele ucabange ngalokhu okulandelayo:

• Iphutha izinhlelo. Kubonakala unomphela noma kungashintshwa umthetho othile ngokuhamba izilinganiso eziningana ipharamitha efanayo. Iphathelene isiphambeko ithuluzi esikalini, inkomba ongaphakeme kudivayisi ukuzwela noma ukunemba amafomula ukubala. Ngokwesibonelo, sokunquma isisindo usebenzisa izinsimbi kanye indiva imithelela buoyancy, idatha etholwe eseduze.
• Iphutha okungahleliwe. It kubangelwa izizathu angenayo ngokwanele kunemiphumela ehlukile ezinganeni ku ukunemba idatha uzimisele. Izinguquko in ezingeni lokushisa elifanele, umfutho womoya, vibration egumbini, emisebeni okungabonakali iyehla iyenyuka emoyeni - lokhu kubonakala yonke izinhlangothi. Gwema thonya akunakwenzeka ngokuphelele.

• Iphutha ukubopha amagugu. Phezu kokuthola amafomula idatha Lesisemkhatsini based ngokuvamile abe sebuningini kwamadijithi emva iphuzu zamadesimali. Isidingo zinciphise isibalo zezinhlamvu ezingu-abese eqala ukubonakala nephutha. Kancane ukunciphisa lezo zinto ezinganembile ngangokunokwenzeka, kokushiya izibalo Lesisemkhatsini by oda eziningana izinombolo ezingaphezu kuka kudingwa umphumela wokugcina.
• Iphutha Ukunganaki (amaphutha) zenzeka ngenxa AMANGA sibalo misincorporated nesilinganiso imikhawulo noma idivayisi iyonke, illegibility of amarekhodi wokuhlolwa. Idatha ngaleyo ndlela etholwe kungahluka kakhulu kulezo izibalo. Ngakho-ke, kufanele basuswe futhi kabusha akhiphe umsebenzi.

Ukumeda density kweqiniso

Uma ucabangela ukuminyana ngeziningi zezinto zokwakha, kubalulekile ukuba sicabangele sibalo kweqiniso. Okusho ukuthi, uma umthamo iyunithi okokusebenza isakhiwo ayiqukethe izimbobo emazinyweni, voids futhi inclusions angaphandle. Ekusebenteni, akukho ukufana ngokuphelele, lapho, isibonelo, ukhonkolo is batheleka isikhunta. Ukuze sithole amandla ayo real, okuyinto incike kwabantu nto eyenziwa imisebenzi elandelayo:

• Isakhiwo is phansi ukugaya a okucolekile. Kulesi sigaba, balahle kusukela ngaleso sikhathi.
• Omisiwe e kuhhavini at lokushisa phezu 100, kusukela isampula asele umswakama isusiwe.
• Selehlile ekamelweni lokushisa badabula ngesihlungo obuhle usayizi anezikhala of 0.20 x 0.20 mm, enika powder iyunifomu.
• Isampula wafakwa ukukalwa ngesikali i ibhalansi ukunemba electronic. Umqulu ibalwa umbhapathizo imitha piston ku isakhiwo ketshezi nezilinganiso okusamanzi dengwane (pycnometry ukuhlaziywa).

Ukubala wenziwa ngokuvumelana formula:

p = m / V

lapho m - mass isampula g;

V - nenani nomthamo cm ^3.

Ngokuvamile kusebenza nesilinganiso density kg / m ^3.

I kwabantu isilinganiso impahla

Ukuze ubone ukuthi ukuziphatha zokwakha ngaphansi kwezimo yokusebenza real lapho zihlatshwa umswakama, amazinga okushisa emihle nemibi, imithwalo mechanical, kubalulekile ukusebenzisa kwabantu isilinganiso. Uchaza isimo ngokomzimba material.

Uma kwabantu kweqiniso - ukubaluleka njalo futhi kuncike kuphela ukwakheka kwamakhemikhali kanye nesakhiwo eheleni crystal we ketshezi, kwabantu isilinganiso kunqunywa porosity isakhiwo. Kuyinto isilinganiso nenqwaba yezinto ezibonakalayo esimweni iyunifomu yenqwaba isikhala matasa vivo.

I kwabantu isilinganiso kunikeza umbono walokho unjiniyela wamandla mechanical, degree of umswakama ukumuncwa, conductivity ezishisayo nezinye izinto ezibalulekile asetshenziswa izakhi ukwakhiwa.

Umqondo density ngobuningi

Ibe sokuba ukuhlaziywa ngobuningi zokwakha (isihlabathi, amatshe, ubumba landiswa futhi abanye.). Isikhombisi esibalulekile ukubala isicelo engabizi izingxenye isakhiwo ezihlukahlukene ingxube. Ibonisa mass isilinganiso zomuthi yenqwaba ngalo anayo isimo isakhiwo okuxekethile.

Ngokwesibonelo, uma yaziwa ngobuningi ukuminyana indaba ka ukuma luyimbudumbudu futhi ngokwesilinganiso okusanhlamvu ukuminyana, kulula ukunquma ipharamitha wokulahlekelwa. Ngo womshini kunilungele ukhonkolo ukusebenzisa yamathebhu (amatshe itshe ochotshoziwe, isihlabathi), ukuba porosity ephansi ndaba ezomile, ngoba uyogcwalisa impahla base usimende, kuzokhuphula izindleko.

Izinkomba kwabantu kwezinye izinto

Uma uthatha amanye ibalwa idatha amatafula, lapho:

• I kwabantu of izinto zamatshe, zikhona ukubunjwa oxides-calcium, i-silicon kanye ne-aluminium amabanga kusuka 2400 kuya 3100 kg ^{m3 ngayinye.}
• Timbers nge phansi cellulose - 1550 kg m ^{3 ngayinye.}
• udaba eziphilayo (carbon, i-oksijini, i-hydrogen) - 800-1400 kg m ^{3 ngayinye.}
• Izinsimbi: steel - 7850 aluminium - 2700, phambili - 11300 kg m ^{3 ngayinye.}

Nge ubuchwepheshe besimanje, ukwakhiwa kwesakhiwo Inkomba kwabantu impahla kubalulekile ngokuya ngamandla umthwalo esindayo izakhiwo. Zonke nangokuvikela umsebenzi nokusebenzisa ungangenisi amanzi izinto kusukela ukuminyana ongaphakeme ivaliwe iseli isakhiwo.
