Capacitance sojntsuam . Capacitance siv cov sensors (los yog Dielectric sensors) siv capacitance ntsuas qhov dielectric permittivity ntawm ib puag ncig nruab nrab. Cov capacitor thiab oscillator tsim ib lub voj voog, thiab cov kev hloov hauv dielectric tas li ntawm cov xov xwm ib puag ncig raug kuaj pom los ntawm kev hloov pauv hauv kev ua haujlwm zaus.
Ib yam li ntawd, nws raug nug, capacitance siv los ntsuas qib li cas?
Lub hauv paus ntsiab lus ntawm Kev ntsuas qib capacitive yog nyob ntawm qhov capacitance pauv a capacitor . Kev sojntsuam thiab lub tank phab ntsa tsim a capacitor nws capacitance yog nyob ntawm tus nqi ntawm cov khoom nyob rau hauv lub tank: Ib lub tank khoob muaj qis dua, lub tank puv siab dua capacitance.
Tom qab, lo lus nug yog, capacitive siab sensors ua haujlwm li cas? Capacitive siab sensors Feem ntau siv cov diaphragm nyias ua ib phaj ntawm lub capacitor. Siv tau siab ua rau lub diaphragm deflect thiab cov capacitance hloov. Qhov kev hloov hauv capacitance tej zaum yuav raug siv los tswj qhov zaus ntawm lub oscillator lossis sib txawv ntawm qhov sib txuas ntawm AC teeb liab los ntawm lub network.
Ib yam li ntawd, ua li cas cov kev ntsuas ntsuas ntsuas ua haujlwm?
Sensor siv conductivity nruab nrab ntawm cov electrode thiab hauv av rau ntes a qib . Cov sensor muaj ib khub ntawm electrodes, thiab siv alternating tam sim no rau lawv. Thaum cov kua npog cov electrodes, nws tsim ib feem ntawm ib qho hluav taws xob Circuit Court, ua rau tam sim no rau ntws.
Dab tsi yog capacitance sensor?
Capacitive qib sensors yog ua los ntawm ob lub electrodes ua ib capacitor , feem ntau nyob rau hauv daim ntawv ntawm ob parallel hlau daim hlau nrog insulating (tsis yog-conductive los yog "dielectric") cov khoom sib cais lawv. Hauv qhov kev nkag siab yooj yim tshaj plaws, capacitors khaws cov hluav taws xob hluav taws xob hauv hluav taws xob.

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
Lub organelle twg yog lub luag haujlwm rau lub zog tshuaj uas xav tau rau lub cell ua haujlwm?
Mitochondria Function Mitochondria feem ntau hu ua "powerhouses" lossis "zog factories" ntawm lub xovtooj vim tias lawv yog lub luag haujlwm rau kev ua adenosine triphosphate (ATP), lub xovtooj ntawm lub zog nqa lub cev
Lub zog zoo li cas yog lub teeb lub zog hloov dua siab tshiab kom lub tshuab xam zauv ua haujlwm?
Kab nyob rau sab saum toj ntawm lub tshuab xam zauv. Ua li cas lub zog yog lub teeb lub zog hloov dua siab tshiab kom lub tshuab xam zauv ua haujlwm? Lawv hloov lub teeb lub zog rau hauv hluav taws xob hluav taws xob. zaub mov
Dab tsi yog qhov haujlwm ntawm kev sojntsuam hauv Southern blot?
Cov daim nyias nyias tau kho nrog ib qho me me ntawm DNA lossis RNA hu ua kev sojntsuam, uas tau tsim los kom muaj cov kab ke uas ua tiav rau ib qho DNA ib ntus hauv cov qauv; Qhov no tso cai rau kev sojntsuam kom hybridize, lossis khi, rau ib qho DNA tshwj xeeb ntawm daim nyias nyias
Cov txheej txheem dab tsi yog lub luag haujlwm rau txoj haujlwm ua haujlwm sib txawv?
Position-effect variegation (PEV) tshwm sim thaum cov noob ib txwm nyob hauv euchromatin yog sib xyaw nrog heterochromatin los ntawm kev hloov kho lossis hloov pauv. Thaum lub ntim ntim heterochromatin kis thoob plaws heterochromatin / euchromatin ciam teb, nws ua rau kev hloov pauv ntawm kev ntsiag to hauv tus qauv stochastic
