解釋
反壓電路-
Planning and designing a microinjection controller on its structure, parameters and circuit tolerance analysis, etc. aspects. based on the primitive electrical microinjection volume controller driven by air - pressure, an improved one with the pressure - keeping function is fabricated. the new controller prevents the dna - fluid from drawing - back by providing a keeping - pressure to it before or after the microinjection
( 2 )對微注射量控制器進行了系統、參數及容差等方面的方案設計,並在原有的基礎上進行了改進,構建了帶保壓裝置的氣壓電控式微注射量控制器,克服了原控制器在注射前或完成後易產生的dna液倒吸現象。
