thiab ncaj qha los ntawm Latin symmetria, los ntawm Greek symmetria "kev pom zoo nyob rau hauv qhov ntev, kev faib ua feem, kev npaj," los ntawm symmetros "muaj ib qho kev ntsuas, txawm, proportionate," los ntawm assimilated daim ntawv ntawm syn- "ua ke" (saib syn-) + metron " ntsuas" (los ntawm PIE hauv paus *me- (2) "raug ntsuas").
Kuj nug, lo lus Greek hauv paus rau symmetry yog dab tsi?
Cov Greek lub hauv paus lo lus rau symmetry ua ke (D). Cov lus symmetry los ntawm lus Greek "symmetria", uas yog tsim los ntawm "syn" (= ua ke) thiab "metron" (= meter). Transcendentalism (A) suav nrog lus root uas txhais tau tias "mus-mus-tshaj".
Ib yam li ntawd, lo lus symmetry yog dab tsi? 1: balanced proportions kuj: kev zoo nkauj ntawm daim ntawv tshwm sim los ntawm balanced proportions. 2: cov cuab yeej ntawm ua symmetrical tshwj xeeb tshaj yog: kev sib txuas lus hauv qhov loj, zoo li, thiab qhov txheeb ze ntawm qhov chaw ntawm qhov sib txawv ntawm txoj kab sib faib lossis nruab nrab dav hlau lossis txog qhov chaw lossis axis - piv ob sab symmetry , cov radial symmetry.
Kuj tseem paub, dab tsi yog Symetrical txhais tau tias?
Txhais ntawm asymmetrical . 1: muaj ob sab los yog ib nrab uas yog tsis zoo ib yam: tsis yog symmetrical ib asymmetrical tsim asymmetrical cov duab. 2 feem ntau asymmetric, ntawm cov pa roj carbon atom: bonded rau plaub txawv atoms los yog pawg. Lwm cov lus los ntawm asymmetrical Ntau Cov Lus Qhia Ntxiv Kawm Ntxiv txog asymmetrical.
Leej twg yog tus tsim ntawm symmetry?
Ib kauj ruam tseem ceeb ntawm no tau ua los ntawm Arthur Cayley, tus kws lej Victorian uas tau pom tias qhov symmetries ntawm tej yam khoom yuav piav los ntawm ib tug lej qauv hu ua a symmetry pab pawg. Qhov no yog qhov pib ntawm kev tshawb nrhiav lej tseem ceeb: kom nkag siab thiab faib txhua yam ua tau symmetry.

Lub luag haujlwm ntawm CDK yog dab tsi hauv lub cev ua haujlwm ntawm tes tshwj xeeb hauv lub voj voog ntawm tes?
Los ntawm phosphorylation, Cdks teeb liab lub xov tooj ntawm tes uas nws tau npaj kom dhau mus rau theem tom ntej ntawm lub voj voog ntawm tes. Raws li lawv lub npe qhia, Cyclin-Dependent Protein Kinases yog nyob ntawm cyclins, lwm chav kawm ntawm kev tswj hwm cov protein. Cyclins khi rau Cdks, ua kom cov Cdks rau phosphorylate lwm cov molecules
Koj puas ntxiv cov kua qaub rau hauv lub hauv paus lossis lub hauv paus rau cov kua qaub?
Ntxiv cov kua qaub ua kom cov concentration ntawm H3O + ions hauv cov tshuaj. Ntxiv ib lub hauv paus txo cov concentration ntawm H3O + ions hauv cov tshuaj. Cov kua qaub thiab lub hauv paus zoo li cov tshuaj tiv thaiv. Yog hais tias lub hauv paus yog ntxiv rau cov kua qaub, cov tshuaj yuav tsis acidic thiab txav mus rau nruab nrab ntawm pH nplai
Koj puas tuaj yeem muab lub voos xwmfab hauv paus los ntawm lub hauv paus square?
Cov Khoom Muag tau nce mus rau Txoj Cai Fais Fab yog qhov tseem ceeb vim tias koj tuaj yeem siv nws los faib cov lus qhia radical. Nco ntsoov tias cov hauv paus hniav zoo ib yam - koj tuaj yeem muab cov hauv paus plaub hau nrog cov hauv paus plaub hau, lossis cov hauv paus hniav nrog lub voos xwmfab, piv txwv li. Tab sis koj tsis tuaj yeem muab lub hauv paus square thiab lub voos xwmfab hauv paus siv txoj cai no
Dab tsi yog tsib lub hauv paus Circuit Court Cheebtsam lawv lub tsev yog dab tsi?
Cov no yog cov feem ntau siv: resistors. Capacitors. LEDs. Transistors. Inductors. Integrated Circuits
Dab tsi yog qhov flux los ntawm lub voos xwmfab ntawm sab yog tias tus nqi ntawm Q yog ntawm ib qho ntawm nws lub ces kaum?
Raws li peb paub tias, tag nrho cov flux los ntawm tus nqi q yog q / ε 0 (Gauss txoj cai). Yog hais tias tus nqi yog nyob rau ntawm lub ces kaum ntawm lub voos xwmfab, ib co ntawm cov flux nkag mus rau hauv lub voos xwmfab thiab tawm los ntawm ib co ntawm nws lub ntsej muag. Tab sis qee qhov flux tsis nkag mus rau hauv lub voos xwmfab. Qhov 1/8th no yuav muab faib ua 3 ntu dua
