Kufufuza Zobisika za Zida Za Crystalline
Pazomwe zimachitika pamagetsi, ma frequency a crystal oscillator ndi ofunikira ngati kugunda kwa mtima. Kulondola ndi kukhazikika kwa zonsezi kumadalira zipangizo zamatsenga zamatsenga. Maonekedwe a zinthu za crystalline, monga zotanuka zotanuka, kachulukidwe, ndi kapangidwe ka atomiki, palimodzi zimatsimikizira ma frequency omaliza a crystal oscillator. Lero, tiyeni tiwulule chinsinsi cha momwe zinthu izi zimakhudzira ma frequency a crystal oscillator.
Zofunika Zakuthupi Zazida za Crystalline
1. Elastic Constants
Zosintha zotanuka za zida za crystalline zimatsimikizira momwe zinthuzo zimapunthira zikamakhudzidwa ndi mphamvu zakunja. Zikuluzikulu zotanuka mosalekeza, ndi ang'onoang'ono mapindikidwe a zinthu pansi pa kupsinjika komweko. Kwa makhiristo, zosinthika zotanuka zimagwirizana mwachindunji ndi ma frequency awo a vibration. Zotanuka zapamwamba nthawi zambiri zimagwirizana ndi kugwedezeka kwamphamvu, chifukwa zinthuzo zimafunikira mphamvu zambiri kuti zipange mapindikidwe omwewo pakugwedezeka.
2. Kuchulukana
Kuchuluka kwa zinthu za crystalline kumakhudzanso kugwedezeka kwawo. Zida zokhala ndi kachulukidwe kakang'ono zimakhala ndi kuchuluka kwakukulu pa voliyumu iliyonse, motero zimafunikira mphamvu zambiri kuti zigwedezeke. Izi nthawi zambiri zimabweretsa kutsika kwa ma frequency a vibration.
3. Kapangidwe ka Atomiki
Makonzedwe a maatomu ndi chikhalidwe cha ma bond mu makristasi amakhudzanso kugwedezeka kwafupipafupi. Mwachitsanzo, ma Si-O bond mu makristalo a quartz ali ndi mphamvu zokulirapo, zomwe zimathandiza kuti makristalo a quartz azigwedezeka kwambiri. Mosiyana ndi izi, mphamvu ya ma bond mu zida za ceramic nthawi zambiri imakhala yotsika, kotero kuti kugwedezeka kwawo kumakhalanso kotsika.
4. Coefficient of thermal Expansion
Coefficient of thermal expansion of crystalline materials ikufotokoza kusintha kwa zinthu pamene kutentha kumasintha. Zida zomwe zimakhala ndi coefficient yotsika ya kuwonjezereka kwa kutentha zimakhala ndi mapindikidwe ochepa pamene kutentha kumasintha, zomwe zimathandiza kuti pakhale kukhazikika kwa kugwedezeka ndipo motero zimakhudza kugwedezeka kwafupipafupi.
5. Dielectric Constant
Dielectric constant ndi kuchuluka kwakuthupi komwe kumafotokoza kuyankha kwazinthu mugawo lamagetsi. Zida zokhala ndi dielectric pafupipafupi nthawi zambiri zimakhala ndi ma frequency apamwamba kwambiri, chifukwa kupindika kwawo mu gawo lamagetsi kumakhala kokulirapo ndipo pamafunika mphamvu zambiri kuti zisungidwe.
6. Kupsyinjika Kwamkati
Kupsinjika kwamkati kumatha kupangidwa panthawi yakukula kwa makhiristo, ndipo kupsinjika kumeneku kumakhudza kapangidwe kawo ndi mawonekedwe ake. Kupsinjika kwamkati kungayambitse kusintha kwa kugwedezeka kwa kristalo.
Chidule
Mwachidule, zinthu zosiyanasiyana zakuthupi za zida za crystalline, kuphatikiza zotanuka, kachulukidwe, kapangidwe ka atomiki, kuchuluka kwa matenthedwe, kukhazikika kwa dielectric, komanso kupsinjika kwamkati, palimodzi zimapanga zinthu zofunika kwambiri zomwe zimakhudza pafupipafupi crystal oscillator. Amalumikizana ndipo amagwira ntchito limodzi kuti adziwe kuchuluka kwa ma frequency ndi kukhazikika kwa crystal oscillator. Kumvetsetsa mgwirizano pakati pa zinthuzi n'kofunika kwambiri popanga ndi kusankha zipangizo zoyenera zamakristali kuti mupeze zizindikiro zolondola komanso zokhazikika.
