It was also found base transversion had a extremely high ocurrence frequency in the single base substitution mutants when the plasmid was replicated in FL-FEN-1〓 cell or MNNG pretreated FL-FEN-1〓 cell, while in all mutants with multiple base substitution there were at least one transversion mutation taken place.

分析还发现，在FL-FEN-1〓细胞自发突变和非定标突变含有单碱基替换突变的突变子中，碱基颠换的发生率极高，而在FL-FEN-1〓细胞自发突变和非定标突变的多碱基替换突变子中，每个突变子均至少含有一个碱基颠换突变。

A frameshift mutation at base position 217 of exon 1 and a T/C missense mutation at base position 59 of exon 3 were found in Yingjing angora rabbit with a high frequency; a T/C same-sense mutation at base position 3 of exon 3 was found with similar frequency in three rabbit breeds.

在外显子1的217位检测到由TCT三碱基插入引起的移码突变，在外显子3的59位和3位分别发生了错义突变由T→C和同义突变由T→C。通过计算发现各位点不同的基因型和等位基因频率在3个兔品种中存在较大的差异，位点A、B在长毛兔和肉兔中均有各自的优势基因型和等位基因。

Optimal mixing ratio of SRA as delay forming agent in cement treated base is 0.05%-0.06%; the influence of compacting delay on strength and dry density of road base may be reduced by SRA additive, forming time may be delayed to 9h; after the forming time is delayed to 4h, 6h and 9h, the strength and dry density shrinkage of cement-treated base with SRA admixture are much less than that of those without SRA.

SRA用作水泥稳定粒料路面基层的延迟成型剂的最佳掺量在0.05％～0.06％：用SRA可降低因延迟压实对水泥稳定粒料基层的强度和干密度的影响，可把延迟成型时间延长到9h；在成型延迟4h，6h，9h后，掺入SRA的水泥稳定粒料的强度和干容度损失明显小于未掺外加剂的混合料在相同延迟成型务件下的强度损失。

In addition, in-situ infrared spectroscopy provides the information about the nature of the surface acid and base sites. For example, Lewis acid and base sites on metal oxides are coordinatively unsaturated metal cations and oxygen anions, respectively, while Brinsted acid and base sites are the hydroxyl groups on the surface.

Three diagnostic criteria for diagnosing AMI were designed, namely cTnⅠ+Myo, cTnⅠ+ H-FABP, and cTnⅠ+H-FABP+Myo. Diagnostic accuracy rating of the three criteria was then calculated and compared. Results Accord- ing to the ROC curves, the cut-off values of the three biochemical markers for diagnosing AMI were defined as follows: Cut-off cTnⅠ 0.5ng/ ml, Cut-off Myo 90ng/ml, and Cut-off H-FABP 5.7ng/ml.
