Abstract: 在工作中,笔者遇到一例症状自发好转的羊水栓塞存活病例。这促使笔者对羊水栓塞的发生机制进行了新的探讨。发现羊水栓塞的临床表现应该用过敏性休克和弥散性血管内凝血的相互作用来解释。笔者对传统的羊水栓塞治疗方法进行了改进,并尝试性地提出了中医治疗弥散性血管内凝血的方法。
Clinically, I fell across a surviving case of amniotic fluid embolism whose symptoms improvedspontaneously. This case impelled me to investigate further the pathogenesis of amniotic fluid embolism. I found that thesymptoms of amniotic fluid embolism should be explained by the reciprocity of anaphylactic shock and disseminatedintravascular coagulation (DIC). Then I ameliorated the traditional therapies of amniotic fluid embolism and tentativelyadvanced the therapies with traditional Chinese medicine for DIC

Abstract: 为了了解应激性溃疡的病因,笔者分析了应激和应激性溃疡的关系、幽门螺杆菌(Hp)感染和应激性溃疡的关系。从分析结果可以发现:应激不能解释应激性溃疡的临床表现;Hp感染可以较好地解释应激性溃疡的临床表现。由此提出假说:Hp感染是应激性溃疡的主要病因。应激性溃疡的治疗应该以抗Hp治疗为主。
To understand the pathogeny of stress ulcer, the author analyzed the relationships between stress ulcerand stress as well as Helicobacter pylori infection. It was found that stress can not be the explanation for the clinicalmanifestations of stress ulcer, while Helicobacter pylori infection can be. So this paper proposed a hypothesis: Helicobacterpylori infection is the primary pathogeny of stress ulcer. The treatment of stress ulcer should focus on suppressingHelicobacter pylori

Abstract: 为探究不同地表覆盖措施在半干旱地区旱作农业生产中的适宜性,在宁夏盐池县进行随机小区试验,设置了4种不同地表覆盖措施(地膜覆盖、砾石覆盖、牲畜粪便覆盖、秸秆覆盖)和对照(无覆盖)对土壤含水量与土壤温度的影响,并比较了玉米的出苗率以及生长状况的差异。试验结果表明:1)地膜覆盖和砾石覆盖具有较好的增温效果,有利于提高玉米的出苗率和促进玉米拔节,并有利于延长作物的生长期;2)4种不同覆盖措施均有一定的保持土壤水分效应,其中牲畜粪便覆盖效果显著;3)4种不同覆盖措施都显著增加了不同生育期玉米的株高、茎粗和叶面积值;4)与对照相比,4种覆盖措施均显著提高了玉米的产量,其中以牲畜粪便覆盖最高,砾石覆盖和地膜覆盖产量次之,秸秆覆盖玉米产量最低。因此,本研究认为当地最适宜的地表覆盖措施为牲畜粪便覆盖,其次为砾石覆盖。
In order to determine the appropriate surface mulching measures in semi-arid areas,an experiment with randomized block design was conducted.The effects of four different soil surface mulching measures (including plastic film mulching,gravel mulching,animal manure mulching,straw mulching) and CK on soil water,temperature,the rate of emergence and maize growth in Yanchi County were investigated.The results showed that:1) Plastic film mulching and gravel mulching displayed good effects of increasing soil temperature which was conducive to the emerging,jointing and prolonging stages of crop development;2) Four soil surface mulching measures preserved the soil moisture,but the effect of animal manure mulching on soil water retention was the most significant;3) Four soil surface mulching measures increased plant height,stem diameter values,leaf area of maize at emergence,jointing,trumpet and heading stages of crop development;4) Four soil surface mulching measures increased the yield of maize,and the yield in the treatment of animal manure mulching was the highest,which followed by gravel mulching and the plastic film mulching compared to the CK.In conclusion,the appropriate surface mulching measure of maize is animal manure mulching followed by gravel mulching under the experiment condition.

Abstract: 通过改变进水碱度、光照条件和溶解氧,对以陶粒为填料的常温低基质上向流厌氧氨氧化生物滤柱的脱氮性能进行了研究.借助克隆测序技术对滤柱内的微生物菌群进行了分析.结果表明,水温为20℃±2℃,水力停留时间为3h条件下,当进水碱度在44~350mg·L-1时,随着碱度的降低,氨氮去除率从97.2%降至75.6%,总氮去除率从89.7%降至75.1%,而亚硝氮去除率稳定在99.7%,进水碱度为0mg·L-1时,出水亚硝氮浓度突跃至4.9mg·L-1.当进水碱度恢复至350mg·L-1,存在自然光照情况下,氨氮去除率较没有光照时的氨氮去除率降低12.3%.水力停留时间为1.5h条件下,当进水DO小于3mg·L-1时,平均氨氮去除率和亚硝氮去除率分别为99.7%和100%,平均总氮去除负荷为1.0kg·(m3·d)-1.16SrRNA克隆测序鉴定结果表明,滤柱下部的厌氧氨氧化菌种类为CandidatusJetteniaasiatica和CandidatusBrocadiasp.,这两种菌对20℃±2℃水温有很好的适应性.

Abstract: 以GPS为辅助,在保安湖主体湖和桥墩湖进行沉水植物调查。将野外调查数据构建GIS数据库,基于GIS软件平台,运用Kringing插值法对保安湖沉水植物分布进行模拟。模拟结果清楚地显示出调查时保安湖沉水植物及4优势种(金鱼藻Ceratophyllum demersum L.、穗状狐尾藻Myriophyllum spicatum L.、微齿眼子菜Potamogeton maackianus A.Benn.及苦草Vallisneria spiralis L.)分别在湖中的分布情况。统计后结果表明沉水植物覆盖面积占全湖面积的92.9%,总生物量(湿重)为143682.4t。比较历史数据,发现湖中水生植被组成特征已由微齿眼子菜绝对优势转变为4种植物的共同优势。

Abstract: 摘要 针对集群系统的多节点多GPU环境,提出一种新型虚拟化GPU计算平台。该平台实现对集群系统所有节点上GPU资源的统一抽象与管理,构建公共GPU资源池。原有GPU应用程序可以不经任何修改而迁移到虚拟化GPU计算平台,并具备访问资源池内任何GPU的能力,编程人员无需显式针对多节点多GPU应用展开MPI编程。应用程序摆脱了单个节点上GPU资源的限制,并具备无差别地访问集群系统中任何可用GPU资源的能力,能有效提高系统总体资源利用率以及吞吐量。采用流水化通信技术,实现对虚拟化GPU计算平台的运行时开销以及节点间数据传输延迟的隐藏。实验表明:与非流水化通信相比,系统总体数据传输延迟降低了50%~70%,具备与节点机本地数据传输等同的通信性能。
Abstract:A virtualized GPU computing platform is proposed for clustered systems, which are often equipped with GPUs in some nodes. All GPUs in system are uniformly abstracted as virtualized ones in a commonly accessed resource pool. Legacy GPU programs can execute on the virtualized GPU computing platform without any modification and any free virtualized GPU in the common resource pool is available to it, which relieves the burden of MPI programming. The platform frees programs with the limit of GPUs in local node and makes it possible for them to access any available GPU in distributed nodes, leading to higher system utilization and throughput. Based on pipelined communication, the run-time overhead and inter-node transmitting latency in virtualized GPU computing platform are hidden by intra-node memory copying and GPU computing. Compared with the non-pipelined communication, the total transmission latency is decreased by approximately 50%-70%. It results in a comparable performance with intra-node local data transmission.

Abstract: 根据复合材料三维黏弹性本构关系,建立了纤维增强复合材料层板高速倾斜冲击损伤的数值分析模型。该模型在复合材料层间引入界面单元模拟层间分层,结合三维Hashin失效准则进行单层板面内损伤识别,引入材料刚度折减方案,采用非线性有限元方法,研究高速倾斜冲击下复合材料层板的破坏过程和损伤特性。研究结果表明:层板的主要损伤形式是层间分层、基体微裂纹和纤维断裂;冲击速度不变而入射角度增大时,剩余速度减小,层板损伤面积在一定入射角度范围内有明显变化;入射角度不变而冲击速度增大时,剩余速度增大,层板损伤面积在一定速度范围内也有明显变化。
