  1. It has made the strong basis for further studying mechanism of replication, virulence and determinant, attenuation, pathogenesis, functions of genetic products, specific diagnosis, cell and host tropism, development of dna vaccine and marker vaccine of csfv, and provided an excellent tool for molecular virology. main research contents include : based on published nucleotide sequences of csfv and by the help of computer analysis software, high conservative regions and single restriction enzyme sites of genome were selected. utilizing rt - pcr and nested - pcr techniques, 7 overlapping cdna fragments covering the full genome of csfv c - strain were successfully amplified

    中國豬瘟兔化毒（脾淋毒）基因組cdna文庫的構建、序列分析：根據已發表的豬瘟病毒（ csfv ）核苷酸序列，藉助計算機軟體分析，選擇高保守區段和基因組中的單一限制性酶切位點，利用rt - pcr及nested - pcr和helf - nestedpcr技術，成功地擴增出了覆蓋c -株全基因組的7個cdna重疊片段f1 f7 ，分別克隆到pmd - 18t或pgem - teasy載體進行測序后，拼接出了其核苷酸序列。
  2. System scheme of speech coding plus spread spectrum communication was presented based on a full analysis of noise characteristic, attenuation characteristic and impedance characteristic of low - voltage power line. spread spectrum carrier ( abbreviated as ssc ) technology is adopted to overcome problems existing in signal transmission over power line. high quality, low rate mbe compression algorithm was used to complete speech encoding and decoding

    在對低壓電力線路的噪聲特性、衰減特性和阻抗特性三個方面充分分析的基礎上，本文提出一種語音編碼+擴頻傳輸的系統總體方案，採用擴頻載波（ spreadspectrumcarrier ，縮寫為ssc ）技術克服電力線傳輸信號存在的問題，採用語音合成質量高並具有較低碼率的mbe壓縮演算法完成語音信號的編解碼。
  3. This novel transmit diversity technique, which combines channel coding, modulation and signal processing at receive terminal, can make full use of the fading multi - path in the wireless communication systems so as to mitigate the signal attenuation. this technique is mainly designed to combat channel fading in downlink transmission by combining the technique of channel coding and that of array diversity, hence increasing the capacity of wireless communications systems and giving diversity gain and coding gain to them

    基於多輸入輸出（ mimo ）的空時編碼技術是實現未來帶寬資源日益緊張的高速無線數據通信系統的重要技術，它結合了通道編碼、調制和接收端的信號處理，能夠充分利用無線通信通道中多散射體環境所造成的多徑，從而提供信號的抗衰落性能。
