定义：在平面内，将一个图形绕一点按某个方向转动一个角度，这样的运动叫做图形的旋转。这个定点叫做旋转中心，转动的角度叫做旋转角。图形的旋转是图形上的每一点在平面上绕着某个固定点旋转固定角度的位置移动，其中对应点到旋转中心的距离相等，对应线段的长度、对应角的大小相等，旋转前后图形的大小和形状没有改变。图形旋转性质：（1）对应点到旋转中心的距离相等。（2）对应点与旋转中心所连线段的夹角等于旋转角。旋转对称中心把一个图形绕着一个点旋转一定的角度后，与原来的图形相吻合，这种图形叫做 旋转对称图形，这个定点叫做 旋转对称中心，旋转的角度叫做 旋转角。（旋转角大于0°小于360°）

Background: Recent studies indicate a strong functional relevance of the canonical inflammatory interleukin 6 signaling pathway in coronary artery disease (CAD). A genetic association of this signaling pathway with CAD has not been shown yet. We aimed to assess novel single nucleotide polymorphisms (SNPs) from genes of the Interleukin 6 signaling pathway. Results: To identify novel SNPs that are relevant for CAD, we employed a large-scale population-based case-control association study of 2199 cases and 1715 controls and assessed 73 SNPs from 12 genes out of the IL-6 signaling pathway. Results were adjusted to the CAD-related risk factors diabetes, hypertension, Body Mass Index, smoking and sex by logistic regression analysis. In a primary explorative study, we identified 5 SNPs that were significantly associated with CAD (MAPK1_rs6928, MAPK1_rs9340, MAPK1_ rs, MAPK14_rs7757672, JAK1_rs310236). After adjustment to CAD-risk factors, MAPK1_ rs6928 showed the strongest association with CAD (P 0.0217, Odds Ratio 1.36, Confidence Interval 1.05 - 1.77). To reproduce this result, we performed a replication study employing independent patient and control panels. In this study we could not approve the association of rs6928 with CAD. Conclusion: In conclusion, we did not detect significant associations of SNPs from the IL-6 signaling pathway with CAD. Our investigation demonstrates the importance of independent replication studies to verify results from candidate-gene association studies in the quest to discover the underlying pathomechanism of CAD.文章引用说明

近年来，由于二硫化钼(MoS2)纳米片具有优异的半导体性能，有可能成为硅的替代者而引起了纳米电子学领域的广泛关注。本文评述了几种制备MoS2纳米片的方法，介绍了MoS2纳米片的表征方法和光电性质，总结了MoS2纳米片在几种光电子器件上的应用，并对MoS2纳米片的发展趋势作了展望。
In recent years, molybdenum disulfide (MoS2) nanosheets have attracted extensive interest in the field of nanoscale electronics and are likely to be an alternative choice for silicon because of its excellent semiconductor performance. In this paper, we review the several methods for preparing MoS2 nanosheets and discuss its optical and electrical properties and other characteristics of the MoS2 nanosheets. The application of MoS2 nanosheets in various optoelectronic devices is introduced. Finally, we also prospect the future development trend about the investigation of MoS2 nanosheets.
