Dynamite Qee zaum siv los ua tus pib lossis txhawb rau AN thiab ANFO explosive tsub nqi.
Ib yam li ntawd, vim li cas dynamite xav tau?
Alfred Nobel qhov kev tsim tawm ntawm lub tshuab tua hluav taws tau ua kom muaj kev tswj xyuas kev tawg ntawm nitroglycerine thiab ua rau nws muaj peev xwm ua kom paub qhov tawg tau muaj zog dua ntawm kev ua lag luam tawg. Nws thib ob tseem ceeb kev tsim kho, dynamite , txhawb kev thauj thiab tuav ntawm nitroglycerine.
Ib yam li ntawd, 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.
Ua raws li qhov no hauv kev txiav txim siab, Dynamite ua li cas kom lub neej yooj yim dua?
Xyoo 1867, Nobel tau tsim dynamite , uas stabilized lub siab heev tawg 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 taw ib hnub tam sim no ua tau.

Vim li cas nws tseem ceeb kom paub tias koj txhais li cas ntxiv?
Txhais qhov seem. Kev txhais cov lus tseem ceeb yog qhov tseem ceeb thaum koj faib ua lej vim tias koj tuaj yeem tau txais qhov teeb meem tsis raug yog tias koj tsis txhais cov seem kom raug. Piv txwv li, nyob rau hauv ib lo lus teeb meem koj yuav tsum tau faib thiab faib tawm rau koj nrog ib tug seem thiab koj yuav tsum tau muab sau tseg
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
Puas tseem ceeb tseem lees txais raws li kev xav hauv chemistry?
Biologists tam sim no xav txog qhov tseem ceeb hauv qhov kev nkag siab no kom tau lees paub los ntawm cov pov thawj empirical, thiab vim li no suav tias nws yog qhov kev tshawb nrhiav kev tshawb fawb superseded
Vim li cas dynamite tseem ceeb heev?
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 qhov thib ob tseem ceeb invention, dynamite, yooj yim thauj thiab tuav ntawm nitroglycerine
