简介：目的将在ICU与多重损害为病人调查外科的治疗。病人们从2006年1月承认了到我们的医院的ICU到2009年1月的163多重损害的方法临床的数据回顾地被学习，包括118男性和45女性，与36.2年的吝啬的年龄(范围，5-67年)。包括的损害区域出发，颈(29个案例)，脸(32个案例)，胸(89个案例)，腹部(77个案例)，骨盆和手足(91个案例)和身体出现(83个案例)。有57个案例，与吃惊相结合。ISS价值从10～54变化了，18.42平均。病人们分别地在在内的ICU接受了外科的治疗24个小时(10个案例)，24-48小时(8个案例)，3-7天(7个案例)和8-14天(23个案例)。为163个病人，结果ICU停留的持续时间从2～29天，与7.56天的平均价值。在他们之中，143被治好(87.73%)，11由于严重出血性的吃惊(6个盒子)在医院(6.75%)里死了，craniocerebral损害(3个盒子)和多重机关失败(2个盒子)，并且9在自愿地从医院(5.52%)排出以后死了。全部的死亡率是12.27%。当多重损害病人在ICU被复活时，损坏控制原则应该被跟随的结论。外科的治疗策略活跃地包括控制出血，对待以前错过的损害和相关创伤或外科的复杂并发症并且动计划阶段手术。

简介：社会风险分类是为社会风险感觉的一个基本、复杂的问题。进行社会风险分类，Tianya论坛帖子作为数据来源，和四种代表被选择：字符串表示，术语频率表示，TF-IDF表示和BBS帖子的分布式的表示被使用。用作为距离度量标准编辑距离或余弦类似，四个k近邻居(kNN)分类器基于不同代表被开发并且比较。由于词顺序的优先级和神经网络模型段向量的语义抽取，kNN为社会风险分类由段向量(kNN-PV)表演有效性基于分布式的表示产生了。而且，通过不同重量，kNN-PV作为一个整体模型与另外的三个kNN分类器被相结合改进社会风险分类的表演。通过蛮力格子搜索方法，最佳的重量被分到不同kNN分类器。与kNN-PV相比，试验性的结果表明整体方法的Macro-F显著地为社会风险分类被改进。

简介：这研究检验多重排的垂直slotted防波提的水动力学表演。我们基于一个特徵函数扩大方法和一种最少的广场技术开发了一个数学模型为司烧秒顺序波浪。为限制双排和三倍排的墙的格获得的数字结果在对以前的研究的结果和试验性的结果的好同意。有思考，传播，和驱散系数的试验性的大小的比较(为双排墙的CR,CT,和CE)证明建议数学模型足够地复制大多数重要特征。我们发现为双排墙，有增加的CR增加挥动数字，kd，并且与减少可渗透的墙部分，dm。CT跟随相反的趋势。CE慢慢地为更低的kd价值与增加的kd增加，到达最大值，然后再减少。另外，dm的一个增加的孔将显著地减少CR,当增加CT时。在kd的更低的价值，一个减少的孔要不是kd的高价值增加CE,，一个减少的孔减少CE。数字结果显示为三倍排的墙，水动力学特征上的房间宽度的安排的效果不是重要的，除了当时kd<0.5。双排slotted防波提可以在kd展出好吸收波浪的表演>0.5，在由水平波浪力量可能比一个单身者的小的地方，围。在另一方面，双排之间的差别和三倍排的垂直slotted防波提是边缘的。
