Umgubo wobisi olusemathinini kunye nomgubo wobisi olusebhokisini, yintoni engcono?
Intshayelelo: Ngokubanzi, umgubo wobisi olungumgubo weentsana upakishwa ikakhulu ezinkonkxeni, kodwa kukho neepakethe ezininzi zomgubo wobisi ezibhokisini (okanye ezingxoweni). Ngokwexabiso lobisi, iitoti zibiza kakhulu kunebhokisi. Yintoni umahluko? Ndiyakholelwa ukuba abathengi abaninzi kunye nabathengi ba...Funda ngokugqithisileyo -
Yintoni Inkqubo yokuPakisha umgubo wobisi?
Yintoni inkqubo yokupakisha umgubo wobisi? Njengoko iteknoloji iguquka, iye yalula kakhulu, ifuna kuphela amanyathelo alandelayo. Inkqubo yokupakisha umgubo wobisi: Ukugqiba iinkonkxa → imbiza yokujika, ukuvuthela kunye nokuhlamba, umatshini wokucoca umgubo → umatshini wokuzalisa umgubo → ibhanti lokuhambisa ipleyiti yetsheyini →umthungo → c...Funda ngokugqithisileyo -
Luluphi uhlobo lokupakisha olufaneleke ngakumbi ukugcinwa komgubo wobisi wosana?
Okokuqala, indima kunye nokubaluleka kokupakishwa kwe-powder yobisi lwentsana Kwinkqubo yokucubungula, ukugcinwa kunye nokuphathwa, ubisi olungumgubo lweentsana luya kuba nemiphumo engathandekiyo kwizondlo kwiiqondo ezahlukeneyo. Ukupakishwa kwahlula ubisi olungumgubo lweentsana kwindawo engqongileyo, ngaloo ndlela kuphelisa...Funda ngokugqithisileyo -

Imodeli elula yemathematika yokuhamba kwamanzi kuhlobo oluqhelekileyo lwe-scraped-surface exchanger ubushushu apho izikhewu phakathi kweencakuba kunye neendonga zesixhobo zimxinwa, ukuze inkcazo yethiyori ye-lubrication yokuhamba isebenze, ibonakaliswe. Ngokukodwa, i-isotherma ezinzileyo ...Funda ngokugqithisileyo -
Intshayelelo yeNkqubo yeMargarine
Imajarini: Sisitofu esisetyenziselwa ukusasaza, ukubhaka nokupheka. Ekuqaleni yayiyilwe endaweni yebhotolo ngo-1869 eFransi nguHippolyte Mège-Mouriès. I-margarine yenziwa ikakhulu nge-hydrogenated okanye i-oyile yezityalo ezisulungekileyo kunye namanzi. Ngelixa ibhotolo yenziwe ngamafutha ...Funda ngokugqithisileyo -

Yintoni umahluko phakathi kwebhotolo kunye nemargarine?
Imargarine iyafana kwincasa kunye nokubonakala kwebhotolo kodwa inomahluko ohlukeneyo. Kwenziwa imajarini endaweni yebhotolo. Ngenkulungwane ye-19, ibhotolo yaba yinto eqhelekileyo ekutyeni kwabantu ababephila ngaphandle komhlaba, kodwa yayibiza kakhulu kwabo bangenayo. Louis...Funda ngokugqithisileyo -
