Taw qhia rau kev faib tawm ntawm kis tau Electron 1.0
1. Loj kis Electron tsom iav tsom iav:
Loj kis tau hluav taws xob tsom iav (cov pa hluav taws xob) feem xyuam} kv, nrog cov qauv sib txawv sib xws nrog cov hluav taws xob sib txawv voltages. Nws cov kev daws teeb meem yog cuam tshuam nrog lub electron Beam nrawm voltage thiab tuaj yeem ncav cuag 0. {}. 1nm. Cov qauv siab kawg tuaj yeem ua tiav qib atomic daws teeb meem.
2. Lub Voltage qis dua hluav taws xob hauv electron tsom iav:
Lub hauv hluav taws xob nqaj ceev voltage (5kv) siv hauv kev sib tw me me (lvem) yog qhov qis dua li ntawm kev xa hluav taws xob loj. Qhov qis dua qhov hluav taws xob voltage yuav ua kom muaj zog sib cuam tshuam ntawm lub teeb hluav taws xob thiab qhov piv txwv, tshwj xeeb yog tsim nyog rau kev kuaj xws li cov polymers thiab muaj sia; Lub caij no, qis-siab xa hluav taws xob electron hub tsom iav ua rau muaj kev puas tsuaj tsawg rau cov qauv.
Kev daws teeb meem yog qis dua li ntawm hluav taws xob loj tsom iav, 1-2 nm. Vim tias siv cov hluav taws xob qis, xa hluav taws xob electron me me, thiab scaning hluav taws xob electron tsom iav tsom iav tuaj yeem sib xyaw rau ntawm ib lub cuab yeej.
3. Khov Kev Xa Khoom Hluav Taws Xob Hluav Taws Xob:
Cryo tsom me me feem ntau yog koom nrog cov qauv ua kom txias rau cov khoom siv hluav taws xob ua kua rau cov khoom siv tsis tu ncua xws li cov protein thiab cov protein. Los ntawm khov cov qauv, kev puas tsuaj tshwm sim los ntawm hluav taws xob nqaj mus rau cov qauv tuaj yeem txo tau tsawg, thiab muaj qhov tseeb tiag tiag piv txwv morphology tuaj yeem tau txais.
