It is divided into three parts: In Part 1, based on mumerical simulations with the pseudo-spectral method, we introduced some new concepts such as the response speed of soliton interaction, the symbol correlation range, etc., and simplified the evolution problem of general soliton sequencies into the evolution problem of finite equivalent classes of words on a unoriented circle, and then gave out the count formula of the equivalent classes by Pó1ya theorem.
全文分三个部分:第一部分以利用拟谱方法所做的大量数值模拟为基础,分析光纤孤子通信系统中一般编码孤子序列的演化性质,提出孤子相互作用传递速度概念,通过考察通信系统的实际情况,引入码元关联长度K,把一般编码孤子序列的演化问题归结为无定向圆环上有限个不等价码字的演化问题,最后利用Pólya定理解决了不等价码字的计数问题。

Attenuation The trp operon is also controlled by attenuation A leader sequence in the polycistronic mRNA upsteam of the coding region of the trpE structural gene encodes a 14 amino acid leader peptide including two tryptophan residues The RNA leader sequence can for several possible stem-loop secondary structures,one of which can act as a transcription terminator whilst a different stem-loop can act as an anti-terminator.
弱化作用 trp 操纵子也受到弱化作用的调控。在trpE结构基因编码区上游的多顺反子mRAN上有一段前导序列,可以编码一个含有14个氨基酸的前导肽,此肽中含有两个色氨酸残基。

Results Mobiligy shifts of SSCP in exon 5 of presenilin-1 was detected in 4 cases with Alzheimer,s disease. Two missense mutation were found in the patients by DNA sequence analyse, one mutation was Leu 130 Met and the other was Vall 57 Leu.Another 11 patients showed one single strend shifted rapidly. But none mobility shifts of SSCP were found in patients with vascular dementia and normal controls. Conclusions It is shown that mutations in exon 5 of presenilin-1 also exist in the patients with sporadic Alzhemer?
结果 发现4名SAD患者的PCR产物SSCP分析发生泳动异常,DNA序列分析发现:这4名SAD患者的130号密码子发生了CTG→ATG错义突变(388位点发生C→A突变),使编码的氨基酸由亮氨酸变为蛋氨酸(Leu 130 Met);157号密码子发生了GTG→CTG错义突变(469位点发生G→C突变),使编码的氨基酸由缬氨酸变为亮氨酸(Val 157 Leu),另有11名患者SSCP表现为一条单链增快,其性质待定。
