Kodi miyendo itatu, tanthauzo lake chipangizo ndi

analangiza kuwerenga mafunso tikamakaona umagwirira phunziro miyendo itatu ndi chifukwa icho chiri. Izo ntchito kuthandiza wogwira mababu, zipangizo, ndi zipangizo zina. Zofunika pakuti osankhidwa ndi heavy pachithandara si waponya uwu pambuyo kukonza chidebe ndi madzi.

Chifukwa chikombole?

Mukamakambirana chomwe miyendo itatu ndi cholinga chachikulu cha ntchito - ndi malo amodzi ndi otetezeka nsinga za zinthu. Mbali Nchito pachithandara kwambiri. Kuwonjezera zasayansi akhoza kumwedwa kupanga.

Kutanthauza miyendo itatu wapeza ntchito kupanga zithunzi. miyendo itatu kapena osakwatiwa-pachithandara ntchito kuwayika pomwepo maso kapena kusefukira. Pali zitsanzo ndi ZOWONJEZERA angapo, nthawi zina wapadera. Zikomo kuti dongosolo limeneli, chithunzicho ndi wa njira zina, ndipo popanda blurring.

Mu umagwirira ndi mankhwala miyendo itatu amathandiza kuti apachike botololo Kutentha kwake. Nthawi zambiri malo anakonza machubu sangakhale vertically. A kuchuluka kwa mfundo detachable molondola anapereka udindo analakalaka danga.

mbali chipangizo

Ife kupereka tanthauzo la zomwe ndi miyendo itatu:

• The chipangizo zida wothandiza zasayansi kuti ntchito kugwira ziwiya ndi ziwiya.
• Mawu "States" amagwiritsidwa ntchito ponena kuti atithandize chonyamulira limene chinachake ananamizira ndi tatifupi kapena zikulumikizana.
• Miyendo itatu yodziwika ndi akhomere zinthu kwa malamulo a clamping chiombankhanga vertically ndi horizontally.
• Nthawi zambiri yopingasa ndi ofukula kamangidwe. Yoyamba zimagwiritsa ntchito kuti akomere machubu. Mu njira yotere facilitates ntchito ndi zipangizo zasayansi.

Ofukula Baibulo ndi zifukwa kulemera kwa mbale yaikulu zitsulo, limene pachithandara zitsulo. Kale Ufumuyo miyendo achepetsa.

Kodi chipangizo?

Kuti kumvetsa zomwe miyendo itatu, muyenera mutidziwe ndi zigawo zake. m'munsi zambiri zachitsulo chosungunula. N'lalikulu ndipo salola kugwa chikombole. Imatha kulemera kusintha kwa pazipita chidebe zotheka wodzazidwa ndi madzi. Posankha katundu zoipa kusiya mankhwala ndiponso kuti anatentha ndi mankhwala a.

Pakuti fasteners flasks, ma chubu oyesera ndi zina zipangizo zasayansi zosinthika yopingasa kuphedwa miyendo itatu angagwiritsidwe ntchito ndi zapansi ziwiri, zoongoka ndi toggle ndodo mu mawonekedwe a kalata P. Iwo likukhalira ku malo ambiri zipangizo chofunika tsiku.

Ntchito ndi chiwerengero chachikulu cha machubu anasankha tripods umodzi gawo kapena Anachotsa ndi maziko lolemera, kuchepetsa chiopsezo monyang'ama unsembe. Maselo onse ndi nambala yapadera kuti magawowa kulemba ndi Kupha chisokonezo pansi akasinja kwambiri kusintha.

kuzinthu

Zochitika za chipangizo ndi akuda ufa wokutira chinyezi kugonjetsedwa, amatha kupirira ndi yochepa mankhwala kuukira mwachisawawa kulephera zosayembekezereka. Nthawi zambiri, mbali zitsulo pamwamba ndi pulasitiki. njira Zimenezi zimathandiza kuti musadandaule kupeza reagents mbali kudzayima.

The kumtunda kwa miyendo itatu pa machubu zopangidwa pulasitiki kapena zitsulo ndi ❖ kuyanika silikoni osakhala zotakasika ndi reagents ndi mankhwala. Pamene awiri gawo ndi ndodo zitsulo, zopangidwa zosapanga dzimbiri ntchito kuumitsa kukonza.

N'zosavuta zitsulo gawo la zinthu yolusa ndi yopangidwa ndi zisulo sanali zikuwononga cha kuchuluka mphamvu zambiri anasankha dzimbiri zachipatala zitsulo.

fasteners

Kufunika yaikulu ya zasayansi miyendo itatu mu njira mankhwala ndi thupi - izo akukonzekera mitundu yonse ya zipangizo zachipatala. Choncho, cholinga chachikulu posankha chipangizo yabwino ndicho kukhala kusinthasintha ntchito. Pa pachithandara chomwecho nthawi zambiri anaika mitundu yoposa 3 tatifupi kuti zosiyanasiyana kwa nkhanizi.

Ogwiritsa zida akhoza zigwirizana zinthu zotsatirazi:

• Mpheto pansi pa tebulo mzimu nyale, babu, ndi mbali zina za zinachitikira.
• Zopalira couplings ali wokwera pa pachithandara kuti akukonzekera pa pamwamba.
• Yaikuluikulu mphete ndi tatifupi ntchito ngati zogwiriziza muli zosiyanasiyana: flasks, machubu mayeso.
• Phazi, clamping mbale pakhosi kapena chonyamulira gawo la chida china.
• Fixers kwa burettes.

msonkhano zinayendera

Mu masukulu makalasi umagwirira anayamba mukudziwa, chimene chiri tanthauzo la zasayansi miyendo itatu. Mokhudzana ndi kutsatira kumvetsetsa chipangizo oyamba kuchitidwa pa msonkhano wake.

Ndi bwino kutsatira sitepe akuyambira:

1. Pamwamba pa tebulo anapereka katundu m'munsi.
2. Front tili m'mavuto pawiri adzatsekeredwa atathana kiyi.
3. Choyamba pa pachithandara kuziluka phiri turntable.
4. The ndondomeko zina amusankha ngati choyezera kwa makamaka ntchito zawo.
5. Pamene kumanga fasteners ali osavomerezeka kugwiritsa ntchito mphamvu kwambiri. Kudalirika kwa pawiri chifukwa zifunike isanafike kuwayika kuthamanga adalira mankhwala dishwashing. Gwiritsani ntchito zinthu muyezo zolinga sinafike ndi Mlengi kumatanthauza mavuto angathe kulephera miyendo itatu. Upambana katundu anakhazikitsa komanso Sikuti, pachithandara sizidzachitidwa, ndipo dongosolo lonse anagwa pa mbali yake.

Akunena pamwamba pa maimidwe unsembe. Ziyenera kukhala lathyathyathya wachibale kwa yopingasa. Iwo ndikoletsedwa kwa zatsopano zasayansi pansi miyendo m'munsi enclose zinthu aliyense nyaze agwirizane kukonza. Tebulo pansi zatsopano ayenera stiffness wabwino ndi kukhala lathyathyathya pamwamba.

Zomwe chitsanzo kusankha?

Ngakhale kuonera zitsanzo alipo ofunitsitsa ndi mtengo wa zimene ndi miyendo itatu pa zimapangidwira. Chifukwa ntchito yapadera chofunika kusankha makhalidwe yoyenera: chiwerengero cha iyambitsa, kutalika ndi mtundu wa poyimitsa, m'munsi thupi, mtundu wa zinthu ❖ kuyanika. Ngati mayesero zina mukhala amodzi, ndalama zoonjezera pa kugula akonzedwa mtengo kukhala zopanda phindu.

Pamene pang'ono zakumwa zikuwononga amaloledwa kugwiritsa ntchito zitsulo poyimitsa wa kanasonkhezereka kapena zosapanga dzimbiri zitsulo. Ntchito ndi machubu mankhwala kufunika polypropylene. Phazi zopalira osankhidwa ❖ kuyanika silikoni, kuti kusokoneza flasks galasi pamwamba ndi achepetsa lapansi.

Zimafunika mankhwala

Kuwaona ku miyendo itatu iliyonse ayenera kulabadira makhalidwe zotsatirazi:

• Mphamvu ya pachithandara ndi nyengo lanu ayenera upambana kangapo kulemera kwa zipangizo ntchito tsiku ndi ziwiya.
• Kutalika kwa pachithandara osankhidwa pang'ono zofunika.
• Mphira zisindikizo ayenera kukonza mbale popanda mfundo zapadera kuphatikana.
• Mukachipinda iyenera kukambidwa ndi zilembo ndi manambala pamene ntchito miyendo itatu pa machubu. Mtengo wa gawo lino mayesero kuchita timatha inu mofulumira kupeza mphamvu anakhumba ndi kuti tisasokoneze ndi reagents ena.
• Pamaso pa mphete zosiyanasiyana, ubwenzi, fixings kwa mtundu wa zinachitikira.
• Atsogolereni kutentha kukana miyendo itatu.
• Mfundo disassembly ndi msonkhano, komanso womasuka yosungirako zinthu kapangidwe.

zitsanzo Universal tripods bwino zasayansi iliyonse. M'masukulu, ndikofunikira chifukwa cha mndandanda yaikulu zowachitikira zosiyana kalasi Chemistry, Biology, Physics. A ophunzira ambiri sasankha chitsanzo cha ofooka mphamvu tripods. Tiyenera chomasuka msonkhano popanda kugwiritsa ntchito makiyi zina.

tipewe ngozi pamene ntchito ndi maimidwe

Iwo akulangizidwa kuwerenga malangizo anapereka kwa kugwira bwino ntchito zipangizo zachipatala. fasteners onse a dongosolo amaloledwa unscrew pokhapokha reagents ndi kuchotsedwa m'dera ntchito. Madzi akatulutsidwa ngati nkotheka. Ngati ndi otentha, kenako mulole kuti mtima ukhale.

flasks The analimbikitsa kuwombera ndi miyendo kutsekedwa. Pamene clamping zinthu zosiyanasiyana, choyamba chapamwamba phazi unscrewed zina sequentially kuchotsa mphamvu otsalira. Musati muyesere kufooketsa ubwenzi tatifupi mwachindunji pachithandara. Choyamba tiyeni tipite phazi, atangodzigwira khosi la botolo yokha.
