  1. Second, as currently study of hot point, back ? emf, it will discuss the principle of the sub - position examination in detail. based on the principle, it put forward a kind of improving back - emf method of crossing - zero checking turns position. but this did n ' t resolve to the root problem that the speed scope is very narrow and it need an in expiation of speed error and so on. thus it put forward a new improvement method at next chapter

    其次,就目前所研究的熱點? ?反勢法,詳細討論了其轉子檢測的原理,在此基礎上提出了一種改進的反勢過點檢測方法,其可直接從機端部得出反勢對地的,而不是通過機中心點來得到反勢。
  2. 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石英基片上製作出損耗小於5db 、有載品因素( ql)超過1000的一系列低損耗、高q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,精心設計路,優化設計布印製路板,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處的單邊帶相噪聲近- 120dbc / hz 、雜波抑制達80db以上的低相噪聲聲表面波振蕩器。
