Using the estimates of character sums over Galois rings and the trace de scription of primitive sequences over Zpe, we obtain an estimate for the frequency of the occurrences of any element in Zpe in one period of a primitive sequence, which is better than Kuzmin's results[1] if n ＞ 4e, where n is the degree of the generating polynomial of the primitive sequence.

范淑琴 ，韩文报文研究了Zpe上本原序列的元素分布。利用Ga，lois环上的指数和估计和本原序列的迹表示，得到了Zpe中各元素在本原序列的一个周期中出现频率的一个估计。当n＞4e时(n为本原序列生成多项式的次数)。我们的估计优于Kuzmin的结果[1]。

Sequence analysis showed that the full-length cDNA sequence of Sc-SAMDC (GenBank Accession number: GQ246459) was 1 968 bp, with three open reading frames, tiny ORF, upstream ORF and main ORF. The mORF was 1200 bp encoding 399 amino acid residues with a molecular mass of 43.6 kD, and the deduced protein had two highly conserved function domains (proenzyme cleavage site and PEST domain).

序列分析显示，甘蔗Sc-SAMDC基因(GenBank Accession number： GQ246459) cDNA全长1968 bp，存在3个读码框（袖珍读码框tORF、上游读码框uORF和主读码框mORF），mORF长1200 bp，编码399个氨基酸的SAMDC酶原，预测分子量为43.6 kD，该酶原含有两个高度保守的功能结构域（酶原剪切位点和PEST结构域）。

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.

为从北京鸭胃肠道中扩增血管活性肠肽基因，根据鸡VIP基因（GenBank登录号X80906），设计了一对简并引物，从北京鸭腺胃、十二指肠和空肠提取总RNA，通过反转录－聚合酶链反应扩增，将从腺胃、十二指肠和空肠中扩增出的产物克隆到pGEM-Teasy载体上，导入大肠杆菌JM109，阳性克隆经双酶切鉴定后测序，将测序结果与鸡和鹅（GenBank登录号为DQ023161）的VIP基因进行同源性比较。

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.
