The results showed that RSAP used two primers of 18 nucleotides in which starting at the 3' end of each primer were restriction site sequences (4-6 bases),followed 12-14 bases of arbitary sequence, the differences between two primers were restriction sites and filler sequence; PCR am-plification was run for the first 5 cycles with an annealing temperature of 35℃, followed by 35 cycles with an annealing temperature of 48℃; the PCR reaction of 25 μL included 20ng DNA templates, 2.5mmol/L of Mg(superscript 2+), 0.2 mmol/L of dNTP, 1.5U of Taq DNA polymerase, 600nmol/L of each primers. RSAP is a new maker technique with simplicity, moderate throughput ratio and reliability. RSAP is of good reprodicibity and broad application.

结果显示，RSAP技术的引物为2条长度均为18bp的引物，引物的3'端为4~6个碱基的限制性酶切位点序列，接着是12~14个碱基的随机序列，2条引物的限制性位点和随机序列不同：PCR扩增的前5个循环采用35℃的退火温度，随后的35个循环采用48℃的退火温度；在25μL反应体系中，模板DNA用量为20ng，Mg(上标 2+)浓度为2.5mmol/L dNIPs浓度为0.2 mmol/L，Tap DNA聚合酶用碳为1.5U，2条引物浓度均为600mmol/L；RSAP技术重复性好，适用性广泛，是一种操作简便、产率中等、稳定可靠的DNA标记技术。

Firstly based on the theory of Semantic Element and the characteristics of phrases and sentences with prepositions,the Semantic Pattern Bases of English prepositions(special Semantic Element Representation Bases for prepositions) were presented.Then the translation process of prepositions was in two steps.One was getting English complete semantic pattern by semantic analysis based on Semantic Pattern Base,the other was deploying into Chinese complete semantic pattern and Chinese representation.
