At present the manufacture of surface acoustic wave use the technology of the final submicron. a series of the devices of low insertion loss, high q saw rayleigh surface acoustic wave resonators or stws that insertion loss has less than 5db, load quality factor ( ql ) is more than 1000 on the quartz piezoelectric with zero of first temperature factor in the research. these difference frequencies are 60mhz, 280mhz, 739mhz and 1ghz of normal frequency and at also surface acoustic wave. using 1. 25db noise factor amplifier, careful design curcuit, good setting printed curcuit board, and using the 1ghz surface transverse wave resonator as frequency element, researching the low phase noise surface acoustic wave with sideband phase noise near ? 120dbc / hz deviating 1khz on carrier, spurious suppress with 80db
本研究採用一階溫度系數為零的壓電石英基片上製作出損耗小於5db 、有載品值因素（ ql值）超過1000的一系列低損耗、高q值聲表面波rayleigh波或stw諧振器，頻率分別為60mhz 、 280mhz 、 739mhz和1ghz等不同頻率的高性能聲表面波諧振器。並採用噪聲系數為1 . 25db的低噪聲系數放大器，精心設計電路，優化設計布置印製電路板，用標稱頻率為1ghz的聲表面波諧振器為頻率控制元件，製作出在偏離載頻1khz處的單邊帶相位噪聲近- 120dbc / hz 、雜波抑制達80db以上的低相位噪聲聲表面波振蕩器。This complex network is highly subject to producing ultrasonic oscillations which can overload the input circuitry of the device at the receiving end ( preamp, amp, etc. )
這個復雜電路通常會產生超聲波震蕩，這能使接收端器材（前級，后級放大器等）的輸入電路過載。The on - board instrument make it possible to study the relationship between ignition parameters and exhaust gas emission. it can also monitor the emission related system and components ( e. g. catalyzer ) in order to keep the the amount of exhaust gas under the permitted limit during the whole life cycle of the automobile
車載廢氣檢測儀不僅為研究點火參數與廢氣排放的關系提供了很大的方便，而且可監測與排放有關的系統和部件（如催化凈化器） ，以保證汽車在整個壽命期限內不超過排放限值。
