Kev lag luam muaj pes tsawg leeg yog lub peev xwm rau ib leeg kev lag luam los sau e-kev pabcuam (tejzaum nws muaj los ntawm qhov sib txawv cov tuam txhab ) los muab cov kev pabcuam muaj nqis ntxiv rau nws cov neeg siv khoom. Kev sib xyaw ntawm e-kev pabcuam muaj ntau yam zoo sib xws nrog kev lag luam txheej txheem (workflow) automation.
Nyob rau hauv no, qhov composition txhais li cas?
Kev sib xyaw yog lwm lo lus rau kev sau ntawv - kev ua ntawm kev sau ntawv lossis daim ntawv sau uas tau txais. Nws kuj hais txog dab tsi yog ua los ntawm. Lo lus muaj pes tsawg leeg los ntawm Latin componere, lub ntsiab lus "ua ke" thiab nws lub ntsiab lus tseem nyob ze rau qhov no. Txhua qhov sib xyaw ntawm cov khoom xyaw tuaj yeem hu ua a muaj pes tsawg leeg.
Ib tug kuj yuav nug, dab tsi yog lub ntsiab lus ntawm muaj pes tsawg leeg hauv chemistry? Tshuaj muaj pes tsawg leeg yog kev npaj, hom, thiab piv ntawm atoms nyob rau hauv molecules ntawm tshuaj tshuaj. Qhov no txhais tau tias tias txoj kev atoms muab tso ua ke hauv ib yam dab tsi txiav txim siab xim, ntom, lub zog, kev ntxhib los mos thiab lwm yam khoom ntawm qhov khoom.
Ib tug kuj yuav nug, dab tsi yog qhov muaj pes tsawg leeg thiab piv txwv?
Lub ntsiab txhais ntawm muaj pes tsawg leeg yog kev ua ntawm muab ib yam dab tsi ua ke, los yog kev sib xyaw ntawm cov ntsiab lus lossis cov khoom zoo. Ib piv txwv ntawm a muaj pes tsawg leeg yog kev ua paj. Ib piv txwv ntawm a muaj pes tsawg leeg yog ib phau ntawv. Ib piv txwv ntawm a muaj pes tsawg leeg yog li cas cov paj thiab vase tau teeb tsa hauv Van Gogh's painting Sunflowers.
Yuav ua li cas koj pib ib tug muaj pes tsawg leeg?
5 Txoj hauv kev los pib lub tsev kawm ntawv theem pib
- Pib Nrog Kab Sib Tham. Qhov no yog ib txoj hauv kev zoo los sim tawm vim tias nws haum rau yuav luag txhua lub ntsiab lus muab.
- Pib Nrog Kev Xav. Qhov no zoo ib yam li ib kab ntawm kev sib tham, tab sis qhov txawv li cas?
- Pib Nrog Kev Ua.
- Pib Nrog Lub Suab.
- Piav txog Daim Duab Siv.

Dab tsi yog cov khoom lag luam hauv kev sib npaug molecular rau kev ua tiav cov tshuaj tiv thaiv ntawm aqueous barium hydroxide thiab nitric acid?
Ba(OH)2 + 2HNO3 → Ba(NO3)2 + 2H2O. Barium hydroxide react nrog nitric acid los tsim barium nitrate thiab dej
Vim li cas kev lag luam tshuaj suav hais tias yog kev lag luam yooj yim?
Kev lag luam tshuaj siv cov khoom siv raw los tsim cov khoom lag luam qhia cov kua qaub, hauv paus, alkali thiab ntsev. Cov khoom siv feem ntau yog siv rau hauv kev tsim khoom ntawm lwm cov khoom lag luam xws li iav, chiv, roj hmab, tawv, ntawv thiab textiles. Yog li, peb tuaj yeem hais tias kev lag luam tshuaj lom neeg yog kev lag luam yooj yim
Dab tsi yog lub ntsiab lus ntawm kev hloov pauv lom neeg hauv cov ntsiab lus ntawm allele zaus?
Microevolution, los yog evolution ntawm ib tug me me, yog txhais raws li ib tug kev hloov nyob rau hauv lub zaus ntawm noob variants, alleles, nyob rau hauv ib tug pej xeem ntau tiam. Lub teb ntawm biology uas kawm txog allele frequencies nyob rau hauv cov pejxeem thiab yuav ua li cas lawv hloov lub sij hawm yog hu ua pej xeem noob caj noob ces
Dab tsi yog txoj cai ntawm kev sib xyaw rau cov khoom sib xyaw?
Rule of Mixtures yog ib txoj hauv kev rau kev kwv yees kwv yees ntawm cov khoom siv sib xyaw, raws li kev xav tias cov khoom sib xyaw yog qhov ntim hnyav nruab nrab ntawm cov theem (matrix thiab dispersed theem) cov khoom
Vim li cas thiaj muaj kev lag luam thiab kev ua lag luam?
Ua thiab lagging strands coli, DNA polymerase uas tswj feem ntau ntawm cov synthesis yog DNA polymerase III. Cov strand no yog ua tsis tu ncua, vim hais tias DNA polymerase yog txav mus rau tib qho kev taw qhia raws li cov diav rawg replication. Qhov no tsis tu ncua synthesized strand yog hu ua tus thawj strand
