  3. After the students graduate from junior middle school, they only mast the ordinary knowledge and some of them ca n ' t even read newspapers well, still less mastering the technology of production and the knowledge of management. therefore, it is quite necessary to develop and do some research about the pattern of exbracurricular biology and scientific education for the peasants " service in the middle school in the countryside. secondly, this thesis sets forth the basis, current situation and aim about the pattern research of biology scientific education for the peasants " service

    論文首先論述了在農村初中課程和教材中呈現的大一統形式,與城市學校課程及教材相差無幾,缺乏地方性和特色性,由於片面追求升學率,很少涉及農村農業和農民問題,導致絕大分學生不能成為優秀學生而白白浪費,造成學生不能學以致用,畢業,只具備最基本的文化知識,甚至有的學生連報紙都念不下,更談不上掌握生產技術、管理知識,因此在國際基礎教育課程改革的大背景下,發展農村初中課外生物科技教育為農服務模式的研究是完可行和可能的,也是十分必要的。
  4. At last, in the circumstances of a wide - band radar is used for target detection, the length of received signal is much longer than that of the transmitted pulse signal. because the traditional matched filter collects only a small part of the energy of received signal, it is not good for detection. the generalized matched filter is obtained by improving the traditional matched filter and can collect all energy of received signal, which is good for detection

    最後,在寬帶條件下,雷達發射脈沖信號,雷達的目標波的長度要遠遠大於發射信號的長度,傳統的匹配濾波只能收集一波信號的能量,這對于檢測電磁散射比較弱的目標是不利的,而廣義匹配濾波對傳統的匹配濾波進行改進,可以將目標波的能量收集起以提高檢測性能。
