为了了解中国气候条件对沥青路面水损害的影响情况,对沥青路面水损害研究成果进行了回顾与分析,认为影响沥青路面水损害的主要气候因素为:降水、高温以及冻融循环过程。降水与高温过程组合以及降水与冻融循环过程组合是影响沥青路面水损害的两个主要气候过程。针对这两个主要气候过程,构建了降水气温指数和降水冰冻指数,用于评价上述气候过程对沥青路面水损害的影响。分析结果表明:利用降水气温指数和降水冰冻指数划分中国公路沥青路面水损害气候影响分区是合理可行的;根据各个气候指数的工程意义和等概率原则,确定了分区界限,拟定了包含14个区的分区方案。

本文就缺口对于两种环氧树脂、聚甲基丙烯酸甲酯和聚碳酸酯的静拉伸强度、低频疲劳强度和蠕变断裂强度的影响进行了研究。结果表明:一种环氧树脂已获得很好的缺口敏感性,而另一种环氧树脂在拉伸负载下显示明显的缺口加强作用。Pcrspex和聚碳酸酯在最小和中等大小缺口时显示小的缺口敏感度,而在最大的缺口时显示缺口加强作用。对于显示缺口加强作用的环氧树脂,亦用不同硬化剂的百分含量进行了研究。有最大的和中等大于缺口的有缺口加强效应;无缺口同有缺口的拉伸强度一样,在14%硬化剂附近显示一峰值。在拉伸负载中,将显示缺口加强作用的环氧树脂在低频疲劳和蠕变负载下进行下面试验。在低频疲劳和长蠕变负载中,其行为明显地相似:对于这种聚合物已发现在最小的和中等缺口时,缺口敏感度是小的,而在最大缺口时有显著的缺口加强效应。将缺口加强行为作为选择复合材料母材的附加标准,是值得推荐的。

Corollary of Marine Eco-system Sustainability by Addressing the Issues of Bycatches

Bipolar radiofrequency ablation of tibialchondroblastomas: A report of three cases

引用

World Journal of Radiology 2012年第7期4卷 335-340页

作者： Prathiba Rajalakshmi Deep N Srivastava Shivanand Gamanagatti pramod kumar Julka Sushma Bhatnagar Shishir Rastogi Department of Radiodiagnosis All India Institute of Medical Sciences New Delhi 110029 India Department of Radiotherapy All India Institute of Medical Sciences New Delhi 110029 India Department of Anaesthesiology All India Institute of Medical Sciences New Delhi 110029 India Department of Orthopedics All India Institute of Medical Sciences New Delhi 110029 India

Chondroblastoma is a rare benign cartilaginous neoplasm of bone. The recurrence rate is high and complications are frequent following open curettage with bone grafting which is the standard treatment forchondroblastomas. We performed radiofrequency ablation in three cases of tibialchondroblastoma using the bipolar system. One patient experienced residual pain for which repeat ablation was performed. No other complications were observed during follow-up. Radiofrequency ablation may offer an effective alternative for the treatment of selected cases of chondroblastoma. The lesion characteristics which are likely to influence treatment outcome and the advantages offered by the bipolar system are discussed.
