The Voronoi structural evolution of silicon upon melting is investigated using a molecular dynamics *** temperatures below the melting point,the solid state system is identified to have a four-fold coordination structure(4,0,0,0).As the temperature increases,the five−fold coordination(2,3,0,0)and six−fold coordination structures(2,2,2,0)and(0,6,0,0)are *** is explained in terms of increasing atomic displacement due to thermal motion and the trapping of the moving atoms by *** temperatures above the melting point,nearly all of the four-fold coordination structures grows into multiple-fold coordination ones.

Evolution of modes in double-clad Raman fiber amplifier

引用

Chinese Physics B 2014年第2期23卷 307-311页

作者：王文亮黄良金冷进勇郭少锋姜宗福 College of Optoelectric Science and Engineering National University of Defense Technology

Stimulated Raman scattering in a double cladding optical fiber is studied with a continuous wave laser used as a pump source. Under various launch conditions, pump modes are differently excited. Considering the mode coupling effect among the pump modes, the evolution of the power in the Stokes modes is studied. The results show that the scattered waves （the Stokes waves） in the fiber core with 9%tm diameter and 0.14 NA could propagate predominantly in the fundamental mode of the fiber by carefully adjusting the pump light launching conditions.

茶叶末釉古瓷作为最早出现的结晶釉之一,开展深入研究可明确其矿物晶体特征、呈色机理以及古代烧制工艺,丰富古陶瓷数据库。目前相关研究多来源于二十世纪末,样本稀少且囊括的年代和窑口严重不足,所用科学仪器多已淘汰,亟需更多实验分析与数据支撑。本文采用光学显微镜(OM)、激光剥蚀电感耦合等离子体质谱(LA-ICP-MS)、扫描电镜-能谱(SEM-EDS)、激光共聚焦拉曼光谱(LRS)、飞行时间二次离子质谱(ToF-SIMS)等现代科学仪器对北宋定窑茶叶末釉样本中矿物晶体开展了分析和表征。结果表明,釉中主晶相与辽金龙泉务窑一致,为钙长石和辉石;釉面整体表现为酱-黑色釉基质富铁(Fe2O3含量均值9.73%)和矿物结晶富铁(Fe2O3含量均值11.33%),除α-Fe2O3和Fe3O4晶体等熔后重结晶矿物,还有铁镁尖晶石、残余高岭石等未融熔矿物,反演出制釉原料中有镁的加入以及烧成温度可能低于1200℃,异于前人高温烧制的观点。SIMS离子成像揭示了胎釉交界处为厚约20~80μm的钙长石晶体层,而非化妆土或玻璃态的致密反应层。研究揭示了茶叶末古瓷中Fe元素不均匀富集,部分区域过饱和而析出含铁矿物晶体,釉面颜色则主要由黄褐色的矿物晶体斑点和酱-黑色玻璃基质共同组成,同时ToF-SIMS在古瓷微区原位的形貌结构和元素分析上效果显著,能够辨别钙长石、碱性长石等微米级矿物。

A 5 kW CW CO2 gas laser was used to produce NiCrBSi superalloy coatings. Powders were preplaced by plasma-spraying. The microstructure and chemical composition of the coating have been studied by SEM, XRD and HREM. The results show the coating microstructure is fine dendrites, composed of gamma matrix, gamma' and boride (NiB) eutectic, the lattice parameter of the gamma matrix is 0.3572 nm and there is a metallurgical bonding in interface.

为保障弹性停车激励机制运营效益,引入排队论中的多级库存管理模式,将多个停车场的停车泊位共享过程转化为竞价有效权在不同停车场间的周转传递过程,本文提出基于Jackson网络的泊位共享竞价有效权分配算法,通过将竞价有效权在各区域停车场的路由选择决策表征为初步判定与二次调整两个阶段,推导其分配过程中有效泊位数稳态分布解及其约束条件,并以美国加州大学伯克利分校为例,探究外部停车需求演化下各子区域停车场的最优分配结果。研究表明:基于Jackson网络的竞价有效权分配算法能使不同子区域停车场在联动运营共享停车政策时,根据外部停车需求与自有共享泊位计算最优的竞价有效权分配数。若各子区域共享泊位配置充足,竞价有效权将按照需求优先级分配予中心区域的停车场,使整体泊位占有率维持在[0.65,0.80]区间;随着泊位不断消耗,当各子区域停车场有效泊位数低于设定阈值时,竞价有效权在路由选择决策下将得到应急补充,使停车场的泊位占有率维持在[0.90,1.00]的高位区间,实现在避免共享泊位出现过饱和状态的同时,减少停车场因空置多余泊位所支付的额外成本。

BACKGROUND:Hepatic veno-occlusive disease(HVOD)is a severe complication of chemotherapy before hematopoietic stem cell transplantation and dietary ingestion of pyrrolizidine *** experimental models were established to study its mechanisms or therapy,but few are *** work aimed at evaluating a rat model of HVOD induced by monocrotaline to help advance research into this disease. METHODS:Thirty-two male rats were randomly classified into 5 groups,and PBS or monocrotaline was administered (100 mg/kg or 160 mg/kg).They were sacrificed on day 7(groups A,B and D)or day 10(groups C and E).Blood samples were collected to determine liver enzyme *** weight of the liver and body and the amount of ascites were *** changes of liver tissue on light microscopy were assessed by a modified Deleve scoring *** positivity of proliferating cell nuclear antigen(PCNA)was estimated. RESULTS:The rats that were treated with 160 mg/kg monocrotaline presented with severe clinical symptoms (including two deaths)and the histopathological picture of *** the other hand,the rats that were fed with 100 mg/kg monocrotaline had milder and reversible *** of the rats sacrificed on day 10 with those sacrificed on day 7 showed that the positivity of PCNA increased,especially that of ***:Monocrotaline induces acute,dose- dependent HVOD in *** model is potentially reversible with a low dose,but reliable and irreversible with a higher *** modified scoring system seems to be more accurate than the traditional one in reflecting the histopathology of *** enhancement of PCNA positivity may be associated with hepatic tissue undergoing recovery.
