Alfred Nobel qhov kev tsim tawm ntawm lub tshuab hluav taws xob tau ua kom muaj kev tswj xyuas kev tawg ntawm nitroglycerine thiab ua rau nws muaj peev xwm ua kom paub qhov tawg tau zoo dua ntawm kev ua lag luam foob pob hluav taws. Nws thib ob tseem ceeb kev tsim kho, dynamite , txhawb kev thauj thiab tuav ntawm nitroglycerine.
Tsuas yog li ntawd, lub hom phiaj ntawm dynamite yog dab tsi?
Nws tau tsim los ntawm Swedish chemist thiab engineer Alfred Nobel nyob rau hauv Geesthacht thiab patented nyob rau hauv 1867. Nws tau txais kev siv dav dav raws li lwm txoj hauv kev rau cov hmoov dub. Hnub no, dynamite yog siv nyob rau hauv mining, quarrying, tsim, thiab demolition industries.

Ib sab ntawm no, Dynamite ua li cas kom lub neej yooj yim dua?
Xyoo 1867, Nobel tau tsim dynamite , uas stabilized lub siab tawg heev nitroglycerin los ntawm nws mus rau hauv ntxeem tau diatomaceous ntiaj teb. Tam sim no Nobel tuaj yeem tsis yog tsuas yog thauj cov nqi them nyiaj nyab xeeb xwb, tab sis kuj tseem txhim kho lub zog ntawm lub foob pob loj. Qhov kev nce qib ntawm ntau ko taw ib hnub tau tam sim no ua tau.
Vim li cas dynamite muaj kev nyab xeeb dua li nitroglycerin?
Dynamite , blasting explosive, patented nyob rau hauv 1867 los ntawm Swedish physicist Alfred Nobel. Dynamite yog nyob ntawm nitroglycerin tab sis yog ntau nyab xeeb dua tuav tshaj nitroglycerin ib leeg. Tom qab ntawd, ntoo pulp tau hloov pauv raws li qhov nqus, thiab sodium nitrate tau ntxiv los ua tus neeg sawv cev oxidizing kom muaj zog ntawm qhov tawg.

Vim li cas San Andreas Fault tseem ceeb heev?
Kev txhaum San Andreas yog qhov tseem ceeb rau ntau qhov laj thawj, tab sis qhov tseem ceeb yog ua nrog keeb kwm ntawm geology. Thaum California tau los ua ib lub xeev, feem ntau yog vim yog kub kub, uas nyiam ntau tus kws tshawb fawb thiab mining engineers
Vim li cas qhov tseem ceeb ntawm qhov tseem ceeb?
Thaum koj pom tus nqi kiag li hauv qhov teeb meem lossis qhov sib npaug, nws txhais tau hais tias txhua yam nyob hauv tus nqi tiag tiag yog qhov zoo. Cov txiaj ntsig tsis zoo feem ntau siv rau hauv cov teeb meem cuam tshuam nrog kev nyob deb thiab qee zaum siv nrog qhov tsis sib xws. Qhov ntawd yog qhov tseem ceeb uas yuav tsum nco ntsoov nws zoo li qhov deb ntawm xoom
Vim li cas cov nuj nqis tseem ceeb tseem ceeb thaum qhia txog kev ntsuas?
Cov duab tseem ceeb yog qhov tseem ceeb los qhia qhov tseeb ntawm koj cov lus teb. Qhov no yog qhov tseem ceeb hauv kev tshawb fawb thiab engineering vim tias tsis muaj cov cuab yeej ntsuas tuaj yeem ua qhov ntsuas nrog 100% precision. Siv cov nuj nqis tseem ceeb tso cai rau tus kws tshawb fawb paub tias cov lus teb meej npaum li cas, lossis qhov tsis paub meej npaum li cas
Yuav ua li cas yog vim li cas tus qauv ntawm ib qho enzyme tseem ceeb heev rau nws txoj haujlwm hauv cov khoom muaj sia?
Enzymes ua kom cov tshuaj tiv thaiv uas tshwm sim hauv cov hlwb. Qhov kev ua haujlwm no cuam tshuam ncaj qha rau lawv cov qauv, nrog rau txhua qhov enzyme tau tshwj xeeb zoo li tus ua kom muaj zog rau ib qho tshuaj tiv thaiv. Kev poob ntawm cov qauv ua rau poob haujlwm. - Kub, pH, thiab kev tswj cov molecules tuaj yeem cuam tshuam rau kev ua haujlwm ntawm cov enzymes
