Cov txheej txheem no yog li pab xaiv qhov zoo tshaj plaws khoom uas augments koj tsim durability, kev ua tau zoo thiab tso zis. Zoo tshaj xaiv cov khoom siv Nws yog ib qho tseem ceeb los xyuas kom meej tias cov khoom tsis succumb rau huab cua thiab ua tau zoo nyob rau hauv unpredictable tej yam kev mob.
Hauv qhov no, kev tsim qauv cuam tshuam rau xaiv cov khoom li cas?
Hauv cov ntsiab lus ntawm cov khoom tsim , lub hom phiaj tseem ceeb ntawm xaiv cov khoom siv yog kom txo tus nqi thaum ua tau raws li cov hom phiaj kev ua tau zoo ntawm cov khoom. Txheej txheem xaiv ntawm qhov zoo tshaj plaws khoom rau daim ntawv thov muab pib nrog cov khoom thiab tus nqi ntawm tus neeg sib tw khoom siv.
Ib yam nkaus, vim li cas kev lag luam thiab xaiv cov khoom ua lub luag haujlwm tseem ceeb hauv kev txiav txim siab tsim qauv txheej txheem? Kev lag luam yam thiab cov khoom xaiv yog ib txwm ua lub luag haujlwm tseem ceeb hauv engineering tsim kev txiav txim siab ua txheej txheem , vim hais tias cov khoom yog manufactured nrog ib tug kim khoom , lawv yuav tsis muag ntawm tus nqi uas tus neeg siv khoom tuaj yeem them taus
Tom qab ntawd, lo lus nug yog, dab tsi yog cov txheej txheem rau kev xaiv cov khoom siv?
Qee tus yam ntxwv tseem ceeb ntawm khoom siv yog: lub zog, durability, yooj, hnyav, tsis kam mus rau tshav kub thiab corrosion, muaj peev xwm cam khwb cia, welded los yog hardened, machinability, hluav taws xob conductivity, thiab lwm yam.
Vim li cas cov khoom tseem ceeb?
Los ntawm pob zeb thiab tooj liab mus rau hlau thiab pob zeb ua ke, khoom siv muaj txiaj ntsig zoo rau lub hom phiaj tshwj xeeb vim tias lawv coj tus cwj pwm hauv qee yam kev mob: lawv muaj cov yam ntxwv tshwj xeeb, uas peb hu ua lawv cov khoom. Nkag siab txog cov khoom no yog dab tsi khoom siv science yog txhua yam hais txog.

Vim li cas kev tsim khoom hauv kev kho mob tseem ceeb?
Productivity - qhov kev ntsuas ntawm cov zis (kev kho mob zoo) ib chav tsev ntawm cov tswv yim (kev noj qab haus huv duas) - yog ib qho kev ntsuas ntawm economic efficiency. Txhawm rau txhim kho cov khoom tsim tau, peb tuaj yeem txo cov nqi thiab tswj qhov ntim lossis nce ntim (piv txwv li, tsim ntau) thiab tswj cov nqi
Vim li cas thiaj tseem ceeb rau qhov tseem ceeb ntawm cov kev cai?
Kev xav tau qhov tseem ceeb yog siv hauv Software tswj cov khoom lag luam los txiav txim siab tus neeg sib tw cov cai ntawm cov khoom lag luam software yuav tsum suav nrog hauv qee qhov kev tso tawm. Cov kev cai tseem ceeb tseem ceeb kom txo qis kev pheej hmoo thaum lub sij hawm kev loj hlob kom cov kev cai tseem ceeb tshaj plaws los yog muaj kev pheej hmoo siab tau ua ntej
Vim li cas nws tseem ceeb los txheeb xyuas cov kev hloov pauv hauv cov neeg siv khoom nyiam?
Nws yog ib qho tseem ceeb rau ID hloov cov neeg siv khoom nyiam vim nws yuav muaj txiaj ntsig zoo rau koj los hloov koj lub lag luam cov khoom / kev pabcuam rau cov kev hloov pauv. Tej zaum koj yuav xav tau sijhawm los npaj los qhia lossis txhawb koj cov neeg siv khoom kom muaj kev sib raug zoo
Dab tsi yog tus tsim khoom tseem ceeb hauv cov khoom noj khoom haus?
Cov neeg tsim khoom tseem ceeb (cov kab mob uas ua rau lawv tus kheej noj los ntawm lub hnub ci thiab / lossis tshuaj lom neeg los ntawm cov seavents sib sib zog nqus) yog lub hauv paus ntawm txhua cov khoom noj - cov kab mob no hu ua autotrophs. Cov neeg siv khoom tseem ceeb yog cov tsiaj uas noj thawj cov neeg tsim khoom; lawv tseem hu ua herbivores (nroog noj)
Tus neeg twg tau soj ntsuam kev mloog lus ntawm kev sib raug zoo los ntawm kev ua ib qho kev sim uas yuav tsum muaj cov tub ntxhais kawm cov ntsiab lus los tswj cov kev mob siab rau cov ntsiab lus hauv kev tshuaj xyuas kev kawm?
Milgram Shock Experiment Ib qho ntawm cov kev tshawb fawb nto moo tshaj plaws ntawm kev mloog lus hauv kev puas siab puas ntsws tau ua los ntawm Stanley Milgram, tus kws kho mob hlwb ntawm Yale University. Nws tau ua ib qho kev sim qhia txog qhov tsis sib haum xeeb ntawm kev mloog lus rau txoj cai thiab lub siab ntawm tus kheej
