1 Njira yopaka ndi njira yopangira filimu yomwe imakwirira zida pa agalasi slide. Zida zopaka utoto zimaphatikizapo zamoyo zokhala ndi cell imodzi, algae ang'onoang'ono, magazi, madzi amtundu wa bakiteriya, minofu yotayirira ya nyama ndi zomera, testis, anthers, ndi zina.
Samalani popaka mafuta:
(1) Galasi slide iyenera kukhalawoyera.
(2) Galasi yotsetsereka ikhale yosalala.
(3) Chophimbacho chiyenera kukhala chofanana. Madzi opaka amatsitsidwa kumanja kwapakati pa slide, ndikufalikira mofanana ndi tsamba la scalpel kapena chotokosera mano.
(4) Chophimbacho chikhale chopyapyala. Gwiritsani ntchito slide ina ngati chopondera, ndikukankhira pang'onopang'ono kuchokera kumanja kupita kumanzere pamwamba pa slide pomwe njira yopaka imadonthozera (mbali yapakati pa zithunzizi ikhale 30 ° -45 °), ndipo ikani wosanjikiza woonda molingana.
(5) Zokhazikika. Pokonzekera, mankhwala opangira mankhwala kapena njira youma (mabakiteriya) angagwiritsidwe ntchito kukonza.
(6) Kudaya. Methylene buluu amagwiritsidwa ntchito pa mabakiteriya, banga la Wright limagwiritsidwa ntchito ngati magazi, ndipo nthawi zina ayodini amatha kugwiritsidwa ntchito. Njira yothetsera utoto iyenera kuphimba malo onse opaka utoto.
(7) Sambani. Zilowerereni zowuma ndi pepala lowuma kapena tositi youma.
(8) Tsekani filimuyo. Kuti musunge nthawi yayitali, sindikizani zithunzizo ndi chingamu cha ku Canada.
2. Njira yopangira mapiritsi ndi njira yopangira mapepala poyika zinthu zamoyo pakati pa galasi lagalasi ndi slide yophimba ndikugwiritsira ntchito mphamvu inayake kuti iphatikize maselo a minofu.
3. Njira yokwera ndi njira yomwe zida zamoyo zimasindikizidwa zonse kuti zipange zowonera. Njirayi ingagwiritsidwe ntchito kupanga mapiri osakhalitsa kapena okhazikika. Zida zopatsira magawo ndi: tinthu tating'onoting'ono monga Chlamydomonas, Spirogyra, Amoeba, ndi nematodes; Hydra, epidermis ya masamba a zomera; mapiko, mapazi, pakamwa pa tizilombo, ma cell amkamwa a epithelial, etc.
Chidwi chiyenera kuperekedwa pakukonzekera njira ya slide:
(1) Pogwira siladiyo, iyenera kukhala yafulati kapena kuyiika papulatifomu. Pothira madzi, kuchuluka kwa madzi kuyenera kukhala koyenera, kotero kuti kumangophimbidwa ndi galasi lophimba.
(2) Zinthuzo ziyenera kuwululidwa ndi singano yochotseratu kapena ma tweezers popanda kuphatikizika, ndikuphwanyidwa pa ndege yomweyo.
(3) Poyika galasi lophimba, phimbani pang'onopang'ono dontho lamadzi kuchokera kumbali imodzi kuti muteteze kuti mpweya usawonekere.
(4) Pamene kudetsa, ikani dontho la madontho mbali imodzi yakuphimba galasi, ndi kuyamwa kuchokera mbali ina ndi pepala loyamwa kuti apange chitsanzo pansi pa galasi lophimba kuti likhale lofanana. Mukapaka utoto, gwiritsani ntchito njira imodzimodziyo, ponyani dontho la madzi, yamwani njira yothimbirira, ndikuyang'ana pa maikulosikopu.
