简介：离开云南漾濞县城,车开向大浪坝。公路一边,晨光还没投射到的小河,像一条充满警惕的乌鱼,偶尔才闪动一下。顺着小河没开多久,车向右一拐,就开始上山了。随着视线的逐渐抬高,我的视野越来越广阔。山路托着车,托着我们,盘旋上升。刚开始的时候,多数树林在我们的头上,被朝阳照得很好看。山路下面,是幽暗的,田野和小河都像刚刚醒来,有点迷糊地在雾气中发呆。而头顶上,树林是新鲜的,透过树林。

简介：作者提出应用土工膜衬护,直接在淤地坝坝面设置溢洪道的坝面过水技术方案,并以宋家沟试验淤地坝为依托工程,进行了现场大型试验.试验研究了平底式与阶梯式两种过水方案.试验结果表明：同等条件下,平底式方案末端最高流速达10.7m/s,而阶梯式方案则为3.1m/s,说明阶梯式方案具有较好的消能作用;在上述流速下,两种方案的结构整体稳定,说明土工膜的铺设结构形式与固定方法是合适的;从耐磨抗冲刷性能看,土工膜抗碎石的耐磨性尚待进一步研究;从施工难度、土工膜用量和成本等方面比较,平底方案具有较大的优越性.

简介：随机的地震倒置是geostatistics和从地震记录，井木头，和geostatistics把信息集成到表面下的模型的以后的概率密度功能(PDF)的地震倒置技术的联合。Markov链蒙特卡罗(MCMC)方法被用来取样以后的PDF，表面下的模型特征能被分析推断一套以后的PDF样品。在这份报纸，我们首先介绍随机的地震倒置理论，讨论并且分析四个关键参数：地震数据signal-to-noise比率(S/N)，variogram，以后的PDF样品数字，和井密度，并且建议这些参数的最佳选择。分析结果证明地震数据S/N调整在地震数据的影响之间的妥协，倒置上的geostatistics结果，variogram控制倒置结果的光滑，以后的PDF样品数字决定统计特征的可靠性源于样品，并且很好，密度影响倒置无常。最后，在随机的地震倒置之间的比较和确定的模型基于地震倒置显示随机的地震倒置能提供表面下的特性的更可靠的信息。

简介：AbstractMandibular condylar fractures are among the most common facial fractures and some of the most difficult to manage. Opinions about the management of mandibular condylar fractures differ among surgeons. With the implementation of new technology, an increased understanding of fracture management, and better functional and morphological outcomes reported in the literature, open reduction and internal fixation is becoming many surgeons’ preferred choice for the treatment of condylar fractures. Because surgical treatment of such fractures is complex, certain factors must be considered to achieve satisfactory outcomes. In this article, we summarise six key points in the management of mandibular condylar fractures: virtual evaluation of condylar fracture, a suitable surgical approach, good reduction, stable internal fixation, repair of the articular disc, and restoration of the mandibular arch width. We believe that these points will help to improve the prognosis of mandibular condyle fractures.
