研究方法：采用随机对照的研究方法，将筛选合格的中风后记忆障碍患者按简单随机法分为：痴复康口服液结合无错性学习组，无错性学习组，阴性对照组。

Five of fifty random primers amplified DNA polymorphism hands in RAPD analysis of seed-derived seedlings and of in vitro regenerated plantlets taken at random. One primer eyen amplified the difference between the regenerated plants. This suggested that there was some variation in DNA in plants of M. sativa regenerated in vitro.

随机选取实生苗和下胚轴愈伤组织再生苗进行RAPD分析，结果表明，所用的50个随机引物中有5个扩增出差异性条带，甚至再生植株之间也有1条引物扩增的条带有差异，这说明经组织培养所得到的再生植株与实生苗相比，在DNA水平上发生了一定程度变异，并且这种变异也存在于再生植株之间。

As the complexity of random fatigue, maney mechanism is not yet clear, the method to use the concept of stochastic process in fatigue is now one of the tendency of random fatigue field.

由于随机疲劳问题的复杂性，许多机理性的问题尚需进一步探讨，但是把随机过程的概念应用于疲劳问题的研究乃是目前随机疲劳课题的发展趋势之一。

The two methods had accurate results in forecasting Cricetulus barabansis, but not in Meriones unguiculatus. It was mainly because Meriones unguiculatus population was affected by environment factors at random, and the dynamic tendency was not obvious. It meant that the two time series methods were accurate for the populations which were little affected by environment factors at random.

两种方法对黑线仓鼠捕获率的预测都比较准确，对长爪沙鼠捕获率的预测结果不准确，主要是因为长爪沙鼠种群数量受周围环境因素的影响随机性较大，趋势不太明显，说明此两种时间序列分析方法适用于受随机因素的影响较小，去掉随机因素的影响后有较好的趋势变化的种群。

The third chapter talked about two different treatments of quantum decoherence in V〓 system. For one the decoherence factor is been expressed in the form of a random external field. And the mean density matrix is calculated to signal the decoherence by showing its nondiagonal elements to approach to zero. In another numerical work done by us, random interaction between system and environment is imposed to mimic the decoherence factor.

第三章讨论了V〓体系中量子相干性研究的两个工作，一个用随机外场来代表消相干因素，采用对系统的密度矩阵进行随机平均的解析方法得到一些结果，一个是我们用数值计算方法的处理，其中消相干因素考虑成系统和环境的相互作用。

A negotiable document having enhanced security for deterring the generation of counterfeit photocopies of the negotiable document, said negotiable document comprising: a front face; a signature area located on the front face; a first pantographic background design creating a seemingly random background covering a first area of the negotiable document; and a second pantographic design creating a seemingly random background covering the signature area of the negotiable document; and a warning clause, located in the signature area, having a background and print that is visible prior to and after any photocopying of the negotiable document and describing the second pantographic design of the signature area.

可协商文档由于加强了安全性可以防止产生影印的赝品可协商文档。这种可协商文档通常由一个封面，封面上的签名区，一个覆盖可协商文档首部的可缩放的背景设计产生一个表面上随机的背景和一个位于签名区的警告条款，这一条款的背景对于影印的可协商文档是可见的并且在影印文档的前面描绘签名区的第二种缩放设计。

The genetic relationships of 11 cultivars and lines in Pennisetum were analyzed using random amplified polymorphic DNA markers. A total of 82 reproducible RAPD fragments were produced using 8 random primers.

利用RAPD分子标记技术分析狼尾草属11个品种12份材料间的遗传关系，结果发现7个引物共扩增出82条带，其中多态性条带为60条，多态位点达73.2%，表明在这11个品种间具有较高的遗传多样性。
