90In this paper, the 10kDa sulfur-rich prolamin gene was amplified by PCR, cloned and sequenced from Chi-nese rice. The sequence analysis showed that the amplified fragment was 380bp long, 94. 5 % homologousto the nucleic acid sequence reported by Masumura et al.

对扩增产物的核苷酸序列分析表明：本扩增产物长 380bp；与 Masumura等人[1] 发表的序列相比，有94.5％的同源性，与我们以前发表的中花10号水稻10kDa富硫醇溶蛋白基因的序列相比，有99.5％的同源性。

In order to clone the VIP gene in the gastrointestinal tract from beijing duck, one pair of specific primers to VIP gene was designed and synthesized according to the chick sequence (X80906). Encoding VIP cDNA fragments were amplified by RT-PCR from the total RNA in the Proventriculus, the Duodenum and the Jejunum of Beijing duck. Their PCR products were ligated into pGEM-T easy vector, which was transformed into E. coil JM109. Positive bacteria clones were screened and identified by PCR method and digested with the double restriction enzyme EcoRⅠ. The sequence of VIP gene fragment was also determined and analyzed.

The key problems of software radio and direct sequence spread spectrum range used in high range radio fuze are discussed. The effects of doppler frequency and carrier's initial random phase are analyzed. A new direct sequence spread spectrum algorithm based on software radio is proposed, by using differential encoding and quadrature demodulating, the effects of doppler frequency and carrier's initial phase on the output of inference filter are eliminated successfully.

A fast extraction method of beer bottle rasied character is introduced in this paper. It is the technique combination of moving target tracking based on dynamic image sequence with edge detection algorithm for speeding up the processing of character extraction to meet the demand of on-line detection in industry. First dynamic image sequence is obtained with an area CCD camera, and the background frames are detected based on the coherence between the background and character image from the video and inevitability of background frames emergence.

运用基于动态图像序列的运动目标跟踪技术，结合图像边缘提取理论中的检测算子模板，提出了一种快速提取啤酒瓶凸性字符的方法：首先采用单个面阵CCD得到啤酒瓶字符的运动图像序列，然后利用背景在运动图像序列中的镜头突变性和出现的必然性，检测视频流中的背景帧，最后采用基于边缘检测的背景配准方法，得到运动图像和校正背景图像的差分图像，恢复出真正的运动物体。
