1. Nlekọta okpomọkụ nke ọma

Site na nhazi oven{{0} oyi akwa okpukpu abụọ, a na-eme ka okpomoku kristal guzosie ike n'ebe mgbanwe okpomọkụ ya (nke a na-emekarị ogo 75-85), na-ebelata mmetụta ngbanwe ọnọdụ okpomọkụ ruo ihe na-erughị 1/100 nke ọkwa mbụ. Usoro njikwa ọnọdụ okpomọkụ a na-egbochi nke ọma n'ụzọ ọgbọ nke mkpọtụ oge na-ebute okpomọkụ.

2. Optimization nke Crystal Materials

6. Ngosipụta akara ngosi mmepụta

A na-ejikọta eriri nkwụsịtụ - nkwusioru n'ime ọkwa mmepụta, na-enye ihe karịrị 40 dB nke nkpuchi maka nke abụọ na 3rd harmonics. Netwọk ndakọrịta impedance na-eme ka ọ dị ọcha nke mgbaama mmepụta n'ofe oke okpomọkụ na-arụ ọrụ.

Ihe ngosi arụmọrụ igodo

Na ngwa bara uru, ngwaahịa OCXO na-agbaso teknụzụ ndị a nwere ike nweta:
