Kev tsov rog ntawm lub xyoo pua nees nkaum tau yuam cov tuam txhab ua caj npab thiab hlau rov ntsuas qhov muaj peev xwm ntawm cov kev lag luam no. Tom qab tag nrho, kev nce qib tsis nyob twj ywm, thiab cov neeg siv khoom xav tau ntau thiab ntau dua cov qauv tshiab ntawm cov khoom. Rau cov neeg uas feem ntau ntsib cov ntsiab lus kev lag luam, lo lus "dawb" tsis yog tshiab. Yog li dab tsi yog qhov khoob?

Vaj ntawm Metallurgy

Txhua lub lauj kaub, lauj kaub tais diav, lub tsheb ncej yog cov hlau uas tau ua tiav hauv txoj kev tshwj xeeb, muab cov duab xav tau. Txhawm rau ua kom cov khoom xa tuaj ntawm lub hauv paus ntau "nyiam", hlau yog tsim nyob rau hauv ib txoj kev tshwj xeeb mus rau hauv ntom monolithic ingots ntawm ntau qhov ntau thiab tsawg. Lub ingot no yog ib qho khoob.

Hlau dov yog paub rau feem ntau ntawm cov pej xeem hauv nroog tsuas yog los ntawm cov yeeb yaj kiab. Tsawg tus neeg paub tias qhov no yog cov txheej txheem txuas ntxiv uas yuav tsum tau txais kev saib xyuas ntau tshaj plaws thiab kev txawj ntse los ntawm cov kws tsim khoom steel. Txhawm rau tiv thaiv cov neeg ua haujlwm ntawm lub khw kub thaum ua haujlwm, lawv tau sim txo lub sijhawm ntawm kev sib cuam tshuam nrog cov xim liab-kub. Cov hlau kub yog nchuav rau hauv pwm tshwj xeeb, tsim cov khoom muag muag.

Nyob hauv kev lag luam khoom siv tes ua, qhov khoob yog hu ua cov qauv lossis cov khoob uas siv rau kev ua haujlwm ntxiv. Nws tsis yog rau tsis muaj dab tsi uas nyob rau hauv cov hnub qub kev npaj tau ua los ntawm cov tub ntxhais kawm lossis cov tub ntxhais kawm uas tau txais lawv txhais tes ntawm kev lag luam xaiv. Ntoo diav, lauj kaub av nplaum yog ib qho piv txwv tiag tiag ntawm qhov no. Nrog lub advent ntawm computer technology, nws tau dhau los ua tus qauv hu rau drives los yog disks blanks. Qhov no tsis siv rau txhua tus, tab sis tsuas yog huv, npaj sau.

tub rog

Ntau qhov kev tsim muaj txiaj ntsig tsuas yog tshwm sim vim tias cov tub rog tab tom nrhiav txoj hauv kev kom nrawm nrawm lossis ua kom lub neej yooj yim rau cov tub rog nyob rau pem hauv ntej. Artillery shells sib pauv ntawm cov neeg sib tw muaj cov duab ntawm lub tog raj kheej elongated, taw tes rau ntawm ib sab. Qhov thib ob ntug yog tiaj tus, uas ua rau nws ua tau rau cov hmoov gases accumulating nyob rau hauv rab phom los thawb nws tawm ntawm lub muzzle.

Cov thooj voos kheej kheej tuaj yeem muaj qhov sib txawv, qhov hnyav, thiab txawm tias hollow sab hauv. Lawv tau siv los nqa cov mines los tiv thaiv cov neeg ua haujlwm, cov ntawv ntawv, shrapnel lossis lwm yam khoom ua kom tuag taus.

Lub sijhawm dhau mus, cov kws tua phom tau paub yuav ua li cas rau kev deb tsis tsuas yog tawg, tab sis kuj tseem ua haujlwm rau cov ntsiab lus no rau qee yam kev ua (lub sijhawm tawg, lub hom phiaj tshawb nrhiav). Rau lawv, qhov khoob yog ib txoj hauv kev kom ua tiav qhov muabcov hom phiaj.
